These must navigate and adapt to ever-shifting external and internal factors while ensuring robustness against process variabilities and unforeseen events. This has a pronounced impact on production control, which serves as the operational intersection between production planning and the shop- floor resources, and necessitates the capability to manage intricate process interdependencies effectively. Considering the increasing dynamics and product diversification, alongside the need to maintain constant production performances, the implementation of innovative control strategies becomes crucial. In recent years, the integration of Industry 4.0 technologies and machine learning methods has gained prominence in addressing emerging challenges in production applications. Within this context, this cumulative thesis analyzes deep learning based production systems based on five publications. Particular attention is paid to the applications of deep reinforcement learning, aiming to explore its potential in dynamic control contexts. Analysis reveal that deep reinforcement learning excels in various applications, especially in dynamic production control tasks. Its efficacy can be attributed to its interactive learning and real-time operational model. However, despite its evident utility, there are notable structural, organizational, and algorithmic gaps in the prevailing research. A predominant portion of deep reinforcement learning based approaches is limited to specific job shop scenarios and often overlooks the potential synergies in combined resources. Furthermore, it highlights the rare implementation of multi-agent systems and semi-heterarchical systems in practical settings. A notable gap remains in the integration of deep reinforcement learning into a hyper-heuristic. To bridge these research gaps, this thesis introduces a deep reinforcement learning based hyper- heuristic for the control of modular production systems, developed in accordance with the design science research methodology. Implemented within a semi-heterarchical multi-agent framework, this approach achieves a threefold reduction in control and optimisation complexity while ensuring high scalability, adaptability, and robustness of the system. In comparative benchmarks, this control methodology outperforms rule-based heuristics, reducing throughput times and tardiness, and effectively incorporates customer and order-centric metrics. The control artifact facilitates a rapid scenario generation, motivating for further research efforts and bridging the gap to real-world applications. The overarching goal is to foster a synergy between theoretical insights and practical solutions, thereby enriching scientific discourse and addressing current industrial challenges.}, language = {en} } @phdthesis{Koehler2024, author = {K{\"o}hler, Wolfgang}, title = {Challenges of efficient and compliant data processing}, doi = {10.25932/publishup-62784}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-627843}, school = {Universit{\"a}t Potsdam}, pages = {195}, year = {2024}, abstract = {Die fortschreitende Digitalisierung ver{\"a}ndert die Gesellschaft und hat weitreichende Auswirkungen auf Menschen und Unternehmen.

Work processes, services, or products must be sensibly adapted to changing times. To be able to analyze and, if necessary, adapt creativity in work processes, a precise understanding of these creative activities is necessary. Process modeling techniques are often used to capture business processes, represent them graphically and analyze them for adaptation possibilities. This has been very limited for creative work. An accurate understanding of creative work is subject to the challenge that, on the one hand, it is usually very complex and iterative. On the other hand, it is at least partially unpredictable as new things emerge. How can the complexity of creative business processes be adequately addressed and simultaneously manageable? This dissertation attempts to answer this question by first developing a precise process understanding of creative work. In an interdisciplinary approach, the literature on the process description of creativity-intensive work is analyzed from the perspective of psychology, organizational studies, and business informatics. In addition, a digital ethnographic study in the context of software development is used to analyze creative work. A model is developed based on which four elementary process components can be analyzed: Intention of the creative activity, Creation to develop the new, Evaluation to assess its meaningfulness, and Planning of the activities arising in the process - in short, the ICEP model. These four process elements are then translated into the Knockledge Modeling Description Language (KMDL), which was developed to capture and represent knowledge-intensive business processes. The modeling extension based on the ICEP model enables creative business processes to be identified and specified without the need for extensive modeling of all process details. The modeling extension proposed here was developed using ethnographic data and then applied to other organizational process contexts. The modeling method was applied to other business contexts and evaluated by external parties as part of two expert studies. The developed ICEP model provides an analytical framework for complex creative work processes. It can be comprehensively integrated into process models by transforming it into a modeling method, thus expanding the understanding of existing creative work in as-is process analyses.}, language = {en} } @phdthesis{Boeken2022, author = {B{\"o}ken, Bj{\"o}rn}, title = {Improving prediction accuracy using dynamic information}, doi = {10.25932/publishup-58512}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-585125}, school = {Universit{\"a}t Potsdam}, pages = {xii, 160}, year = {2022}, abstract = {Accurately solving classification problems nowadays is likely to be the most relevant machine learning task. Binary classification separating two classes only is algorithmically simpler but has fewer potential applications as many real-world problems are multi-class. On the reverse, separating only a subset of classes simplifies the classification task. Even though existing multi-class machine learning algorithms are very flexible regarding the number of classes, they assume that the target set Y is fixed and cannot be restricted once the training is finished. On the other hand, existing state-of-the-art production environments are becoming increasingly interconnected with the advance of Industry 4.0 and related technologies such that additional information can simplify the respective classification problems. In light of this, the main aim of this thesis is to introduce dynamic classification that generalizes multi-class classification such that the target class set can be restricted arbitrarily to a non-empty class subset M of Y at any time between two consecutive predictions. This task is solved by a combination of two algorithmic approaches. First, classifier calibration, which transforms predictions into posterior probability estimates that are intended to be well calibrated. The analysis provided focuses on monotonic calibration and in particular corrects wrong statements that appeared in the literature. It also reveals that bin-based evaluation metrics, which became popular in recent years, are unjustified and should not be used at all. Next, the validity of Platt scaling, which is the most relevant parametric calibration approach, is analyzed in depth. In particular, its optimality for classifier predictions distributed according to four different families of probability distributions as well its equivalence with Beta calibration up to a sigmoidal preprocessing are proven. For non-monotonic calibration, extended variants on kernel density estimation and the ensemble method EKDE are introduced. Finally, the calibration techniques are evaluated using a simulation study with complete information as well as on a selection of 46 real-world data sets. Building on this, classifier calibration is applied as part of decomposition-based classification that aims to reduce multi-class problems to simpler (usually binary) prediction tasks. For the involved fusing step performed at prediction time, a new approach based on evidence theory is presented that uses classifier calibration to model mass functions. This allows the analysis of decomposition-based classification against a strictly formal background and to prove closed-form equations for the overall combinations. Furthermore, the same formalism leads to a consistent integration of dynamic class information, yielding a theoretically justified and computationally tractable dynamic classification model. The insights gained from this modeling are combined with pairwise coupling, which is one of the most relevant reduction-based classification approaches, such that all individual predictions are combined with a weight. This not only generalizes existing works on pairwise coupling but also enables the integration of dynamic class information. Lastly, a thorough empirical study is performed that compares all newly introduced approaches to existing state-of-the-art techniques. For this, evaluation metrics for dynamic classification are introduced that depend on corresponding sampling strategies. Thereafter, these are applied during a three-part evaluation. First, support vector machines and random forests are applied on 26 data sets from the UCI Machine Learning Repository. Second, two state-of-the-art deep neural networks are evaluated on five benchmark data sets from a relatively recent reference work. Here, computationally feasible strategies to apply the presented algorithms in combination with large-scale models are particularly relevant because a naive application is computationally intractable. Finally, reference data from a real-world process allowing the inclusion of dynamic class information are collected and evaluated. The results show that in combination with support vector machines and random forests, pairwise coupling approaches yield the best results, while in combination with deep neural networks, differences between the different approaches are mostly small to negligible. Most importantly, all results empirically confirm that dynamic classification succeeds in improving the respective prediction accuracies. Therefore, it is crucial to pass dynamic class information in respective applications, which requires an appropriate digital infrastructure.}, language = {en} } @phdthesis{Baum2023, author = {Baum, Katharina}, title = {Social networking sites}, school = {Universit{\"a}t Potsdam}, pages = {281}, year = {2023}, language = {en} } @phdthesis{Dannenmann2023, author = {Dannenmann, Barbara}, title = {K{\"o}nnen technologiegest{\"u}tzte Verhandlungstrainings unter Einsatz von K{\"u}nstlicher Intelligenz und Virtueller Realit{\"a}t das Vertriebstraining verbessern?}, doi = {10.25932/publishup-57737}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-577378}, school = {Universit{\"a}t Potsdam}, pages = {245}, year = {2023}, abstract = {Digitale und gesellschaftliche Entwicklungen fordern kontinuierliche Weiterbildung f{\"u}r Mitarbeiter im Vertrieb.

This study aims to determine the effect of visionary leadership on employees' perceived job satisfaction. Specifically, it investigates whether the mediators meaningfulness at work and commitment to the leader impact the relationship. I take support from job demand resource theory to explain the overarching model used in this study and broaden-and-build theory to leverage the use of mediators. To test the hypotheses, evidence was collected in a multi-source, time-lagged design field study of 95 leader-follower dyads. The data was collected in a three-wave study, each survey appearing after one month. Data on employee perception of visionary leadership was collected in T1, data for both mediators were collected in T2, and employee perception of job satisfaction was collected in T3. The findings display that meaningfulness at work and commitment to the leader play positive intervening roles (in the form of a chain) in the indirect influence of visionary leadership on employee perceptions regarding job satisfaction. This research offers contributions to literature and theory by first broadening the existing knowledge on the effects of visionary leadership on employees. Second, it contributes to the literature on constructs meaningfulness at work, commitment to the leader, and job satisfaction. Third, it sheds light on the mediation mechanism dealing with study variables in line with the proposed model.

Their functionalities allow users to connect and interact with others and weave complex social networks in which social information is continuously disseminated between users. Besides the social value SNSs are generating, they likewise attract companies and allow for new forms of marketing, thereby creating considerable economic value alike. However, as SNSs grew in popularity, so did concerns about the impact of their use on social interactions in general and the well-being of individual users in particular. While existing scientific evidence points to both risk as well as benefits of SNS use, research still lacks a profound understanding of which aspects of SNSs enable an impact on well-being and which psychological processes on the part of the users underly and explain this relationship. Therefore, this thesis is dedicated to an in-depth exploration of the relationship between SNS use and well-being and aims to answer how SNS use can impact well-being. Primarily, it focuses on the unique technological features that characterize SNSs and enable potential well- being alterations and on specific psychological processes on the part of the users, underlying and explaining the relationship. For this purpose, the thesis first introduces the concept of well- being. It continues by presenting SNSs' unique technological features, divided into specifics of the content disseminated on SNSs and the network structure of SNSs. Further, the thesis introduces three classes of psychological processes assumed most relevant for the relationship between SNSs and well-being: other-focused, self-focused, and contrastive processes.. It is assumed that the course and quality of these common processes change in the SNS context and that a complex interplay between the unique features of SNSs and these processes determines how SNSs may ultimately affect users' well-being - both in positive and negative ways. The dissertation comprises seven research articles, each of which focusses on a particular set of SNS characteristics, their interplay with one or more of the proposed psychological processes, and ultimately the resulting effects on user well-being or its key resilience and risk factors. The seven articles investigate this relationship using different methodological approaches. Three articles are based on either systematic or narrative literature reviews, one applies an empirical cross-sectional research design, and three articles present an experimental investigation. Thematically, two articles revolve around SNS use's effect on self-esteem. Three articles examine the specific role of the emotion of envy and its potential to establish and perpetuate a well-being-damaging social climate on SNSs. The two last articles of this thesis revolve around the established assumption that active and passive SNS use, as different modalities of SNS use, cause differential effects on users' well-being due to the involvement of different psychological processes. The results of this thesis illustrate different ways how SNSs can affect users' well-being. The results suggest that especially contrastive processes play a decisive role in explaining potential well-being risks for SNS users. Their interplay with certain SNS features seems to foster upward social comparisons and feelings of envy, potentially leading to a complex set of deleterious effects on users' well-being. At the same time, the findings illuminate ways in which SNSs can benefit users and their self-esteem - especially when SNS use promotes self- focused and social-feedback-based other-focused processes. The thesis and their findings illustrate that the relationship between SNSs and well-being is complex. Therefore, a nuanced perspective, taking into consideration both the technological uniqueness of SNSs and the psychological processes they are enabling, is crucial to understand how these technologies affect their users in good and potentially harmful ways. On the one hand, the gathered insights contribute to research, providing novel insights into the complex relationship between SNS use and well-being. On the other hand, the results enable a focused and action-oriented derivation of recommendations for stakeholders such as individual users, policymakers, and platform providers. The findings of this thesis can help them to better combat SNS-related risks and ultimately ensure a healthy and sustainable environment for users - and thus also the economic values of SNSs - in the long term.}, language = {en} } @phdthesis{Brinkmann2022, author = {Brinkmann, Maik}, title = {Towards a joint public service delivery?

By developing joint public service delivery with other stakeholders, public administrations can respond to these challenges. This increases the importance of inter-organizational governance—a development often referred to as New Public Governance, which to date has not been realized because public administrations focus on intra-organizational practices and follow the traditional "governmental chain." E-government initiatives, which can lead to high levels of interconnected public services, are currently perceived as insufficient to meet this goal. They are not designed holistically and merely affect the interactions of public and non-public stakeholders. A fundamental shift toward a joint public service delivery would require scrutiny of established processes, roles, and interactions between stakeholders. Various scientists and practitioners within the public sector assume that the use of blockchain institutional technology could fundamentally change the relationship between public and non-public stakeholders. At first glance, inter-organizational, joint public service delivery could benefit from the use of blockchain. This dissertation aims to shed light on this widespread assumption. Hence, the objective of this dissertation is to substantiate the effect of blockchain on the relationship between public administrations and non-public stakeholders. This objective is pursued by defining three major areas of interest. First, this dissertation strives to answer the question of whether or not blockchain is suited to enable New Public Governance and to identify instances where blockchain may not be the proper solution. The second area aims to understand empirically the status quo of existing blockchain implementations in the public sector and whether they comply with the major theoretical conclusions. The third area investigates the changing role of public administrations, as the blockchain ecosystem can significantly increase the number of stakeholders. Corresponding research is conducted to provide insights into these areas, for example, combining theoretical concepts with empirical actualities, conducting interviews with subject matter experts and key stakeholders of leading blockchain implementations, and performing a comprehensive stakeholder analysis, followed by visualization of its results. The results of this dissertation demonstrate that blockchain can support New Public Governance in many ways while having a minor impact on certain aspects (e.g., decentralized control), which account for this public service paradigm. Furthermore, the existing projects indicate changes to relationships between public administrations and non-public stakeholders, although not necessarily the fundamental shift proposed by New Public Governance. Lastly, the results suggest that power relations are shifting, including the decreasing influence of public administrations within the blockchain ecosystem. The results raise questions about the governance models and regulations required to support mature solutions and the further diffusion of blockchain for public service delivery.}, language = {en} } @phdthesis{Brenner2022, author = {Brenner, Andri Caspar}, title = {Sustainable urban growth}, doi = {10.25932/publishup-55522}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-555223}, school = {Universit{\"a}t Potsdam}, pages = {231}, year = {2022}, abstract = {This dissertation explores the determinants for sustainable and socially optimalgrowth in a city.

On the one hand, digital technologies have emerged, diffusing and determining our private and professional lives. On the other hand, digital platforms have leveraged the potentials of digital technologies to provide new business models. These dynamics have a massive effect on individuals, companies, and entire ecosystems. Digital technologies and platforms have changed the way persons consume or interact with each other. Moreover, they offer companies new opportunities to conduct their business in terms of value creation (e.g., business processes), value proposition (e.g., business models), or customer interaction (e.g., communication channels), i.e., the three dimensions of DT. However, they also can become a threat for a company's competitiveness or even survival. Eventually, the emergence, diffusion, and employment of digital technologies and platforms bear the potential to transform entire markets and ecosystems. Against this background, IS research has explored and theorized the phenomena in the context of DT in the past decade, but not to its full extent. This is not surprising, given the complexity and pervasiveness of DT, which still requires far more research to further understand DT with its interdependencies in its entirety and in greater detail, particularly through the IS perspective at the confluence of technology, economy, and society. Consequently, the IS research discipline has determined and emphasized several relevant research gaps for exploring and understanding DT, including empirical data, theories as well as knowledge of the dynamic and transformative capabilities of digital technologies and platforms for both organizations and entire industries. Hence, this thesis aims to address these research gaps on the IS research agenda and consists of two streams. The first stream of this thesis includes four papers that investigate the impact of digital technologies on organizations. In particular, these papers study the effects of new technologies on firms (paper II.1) and their innovative capabilities (II.2), the nature and characteristics of data-driven business models (II.3), and current developments in research and practice regarding on-demand healthcare (II.4). Consequently, the papers provide novel insights on the dynamic capabilities of digital technologies along the three dimensions of DT. Furthermore, they offer companies some opportunities to systematically explore, employ, and evaluate digital technologies to modify or redesign their organizations or business models. The second stream comprises three papers that explore and theorize the impact of digital platforms on traditional companies, markets, and the economy and society at large. At this, paper III.1 examines the implications for the business of traditional insurance companies through the emergence and diffusion of multi-sided platforms, particularly in terms of value creation, value proposition, and customer interaction. Paper III.2 approaches the platform impact more holistically and investigates how the ongoing digital transformation and "platformization" in healthcare lastingly transform value creation in the healthcare market. Paper III.3 moves on from the level of single businesses or markets to the regulatory problems that result from the platform economy for economy and society, and proposes appropriate regulatory approaches for addressing these problems. Hence, these papers bring new insights on the table about the transformative capabilities of digital platforms for incumbent companies in particular and entire ecosystems in general. Altogether, this thesis contributes to the understanding of the impact of DT on organizations and markets through the conduction of multiple-case study analyses that are systematically reflected with the current state of the art in research.

Incumbents are particularly exposed to the field of tension between maintaining and renewing their business model. Banking is one of the industries most affected by digitalization, with a large stream of digital innovations around Fintech. Most research contributions focus on digital innovations, such as Fintech, but there are only a few studies on the related challenges and perspectives of incumbent organizations, such as traditional banks. Against this background, this dissertation examines the specific causes, effects and solutions for traditional banks in digital transformation - an underrepresented research area so far. The first part of the thesis examines how digitalization has changed the latent customer expectations in banking and studies the underlying technological drivers of evolving business-to-consumer (B2C) business models. Online consumer reviews are systematized to identify latent concepts of customer behavior and future decision paths as strategic digitalization effects. Furthermore, the service attribute preferences, the impact of influencing factors and the underlying customer segments are uncovered for checking accounts in a discrete choice experiment. The dissertation contributes here to customer behavior research in digital transformation, moving beyond the technology acceptance model. In addition, the dissertation systematizes value proposition types in the evolving discourse around smart products and services as key drivers of business models and market power in the platform economy. The second part of the thesis focuses on the effects of digital transformation on the strategy development of financial service providers, which are classified along with their firm performance levels. Standard types are derived based on fuzzy-set qualitative comparative analysis (fsQCA), with facade digitalization as one typical standard type for low performing incumbent banks that lack a holistic strategic response to digital transformation. Based on this, the contradictory impact of digitalization measures on key business figures is examined for German savings banks, confirming that the shift towards digital customer interaction was not accompanied by new revenue models diminishing bank profitability. The dissertation further contributes to the discourse on digitalized work designs and the consequences for job perceptions in banking customer advisory. The threefold impact of the IT support perceived in customer interaction on the job satisfaction of customer advisors is disentangled. In the third part of the dissertation, solutions are developed design-oriented for core action areas of digitalized business models, i.e., data and platforms. A consolidated taxonomy for data-driven business models and a future reference model for digital banking have been developed. The impact of the platform economy is demonstrated here using the example of the market entry by Bigtech. The role-based e3-value modeling is extended by meta-roles and role segments and linked to value co-creation mapping in VDML.

Die Zielstellung der Dissertation wurde somit dahingehend spezifiziert, diejenigen Faktoren zu analysieren, die dazu beitragen k{\"o}nnen, dass die relative Repr{\"a}sentation von Frauen im Segment der zehn gr{\"o}ßten Wirtschaftspr{\"u}fungsge-sellschaften Deutschlands ab der Manager-Ebene (d. h. {\"u}blicherweise ab der Schwelle der examinierten Wirtschaftspr{\"u}fer/innen) sinkt. Der Fokus der Analyse liegt daher auf Ebene der erfahrenen Pr{\"u}fungsassistenten und Pr{\"u}fungsassistentin-nen (Senior), um diese Schwelle unmittelbar vor der Manager-Ebene detailliert zu beleuchten. Neben der Auswertung von Erkenntnissen aus der internationalen Pr{\"u}fungsfor-schung wurde eine empirische Studie unter den Senior von sechs der zehn gr{\"o}ßten Wirtschaftspr{\"u}fungsgesellschaften in Deutschland durchgef{\"u}hrt. Die empirischen Ergebnisse wurden mittels deskriptiver Datenanalyse ausgewertet und dahinge-hend analysiert, f{\"u}r welche der zuvor definierten Aspekte signifikante geschlechts-spezifische Unterschiede zu beobachten sind. F{\"u}r ausgew{\"a}hlte Aspekte wurde zu-dem analysiert, ob es Unterschiede zwischen weiblichen/m{\"a}nnlichen Senior mit Kind/ern und ohne Kind/er gibt. Insgesamt wurden f{\"u}r zahlreiche Aspekte ge-schlechtsspezifische Unterschiede und Unterschiede zwischen Senior mit Kind/ern und ohne Kind/er gefunden. Es zeigt sich außerdem, dass neben der beruflichen Situation auch die individuellen Eigenschaften und das private Umfeld von Bedeu-tung sind. Im Rahmen der beruflichen Situation spielen sowohl die Wahrnehmung der aktuellen beruflichen Situation eine Rolle als auch u. a. die Erwartungen der Senior an die m{\"o}gliche k{\"u}nftige Manager-Position, an das Wirtschaftspr{\"u}fungsexa-men und an weitere berufliche Perspektiven.}, language = {de} } @phdthesis{Schmidt2021, author = {Schmidt, Robert}, title = {Gr{\"u}ndungsf{\"o}rderung an Hochschulen}, doi = {10.25932/publishup-52520}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-525203}, school = {Universit{\"a}t Potsdam}, pages = {XIII, 270, ix}, year = {2021}, abstract = {F{\"o}rdermittelfinanzierte Gr{\"u}ndungsunterst{\"u}tzungsangebote waren in den EU-F{\"o}rderperioden 2007-2013 und 2014-2020 ein wichtiges Element der Hochschulgr{\"u}ndungsf{\"o}rderung im Land Brandenburg.

And as societies, we condemn inequalities that are rooted in immutable circumstances such as gender, race, and parental background. Consequently, policy makers are interested in measuring and understanding the causes of health inequalities rooted in circumstances. However, identifying causal estimates of these relationships is very ambitious for reasons such as the presence of confounders or measurement error in the data. This thesis contributes to this ambitious endeavour by addressing these challenges in four chapters. In the first Chapter, I use 25 years of rich health information to describe three features of intergenerational health mobility in Germany. First, we describe the joint permanent health distribution of the parents and their children. A ten percentile increase in parental permanent health is associated with a 2.3 percentile increase in their child's health. Second, a percentile point increase in permanent health ranks is associated with a 0.8\% to 1.4\% increase in permanent income for, both, children, and parents, respectively. Non-linearities in the association between permanent health and income create incentives to escape the bottom of the permanent health distribution. Third, upward mobility in permanent health varies with parental socio-economic status. In the second Chapter, we estimate the effect of maternal schooling on children's mental health in adulthood. Using the Socio-Economic Panel and the mental health measure based on the SF-12 questionnaire, we exploit a compulsory schooling law reform to identify the causal effect of maternal schooling on children's mental health. While the theoretical considerations are not clear, we do not find that the mother's schooling has an effect on the mental health of the children. However, we find a positive effect on children's physical health operating mainly through physical functioning. In addition, albeit with the absence of a reduced-form effect on mental health, we find evidence that the number of friends moderates the relationship between maternal schooling and their children's mental health. In the third Chapter, against a background of increasing violence against non-natives, we estimate the effect of hate crime on refugees' mental health in Germany. For this purpose, we combine two datasets: administrative records on xenophobic crime against refugee shelters by the Federal Criminal Office and the IAB-BAMF-SOEP Survey of Refugees. We apply a regression discontinuity design in time to estimate the effect of interest. Our results indicate that hate crime has a substantial negative effect on several mental health indicators, including the Mental Component Summary score and the Patient Health Questionnaire-4 score. The effects are stronger for refugees with closer geographic proximity to the focal hate crime and refugees with low country-specific human capital. While the estimated effect is only transitory, we argue that negative mental health shocks during the critical period after arrival have important long-term consequences. In the last Chapter of this thesis, we investigate how the economic consequences of the pandemic and the government-mandated measures to contain its spread affect the self-employed - particularly women- in Germany. For our analysis, we use representative, real-time survey data in which respondents were asked about their situation during the COVID-19 pandemic. Our findings indicate that among the self-employed, who generally face a higher likelihood of income losses due to COVID-19 than employees, women are 35\% more likely to experience income losses than their male counterparts. We do not find a comparable gender gap among employees. Our results further suggest that the gender gap among the self-employed is largely explained by the fact that women disproportionately work in industries that are more severely affected by the COVID-19 pandemic. Our analysis of potential mechanisms reveals that women are significantly more likely to be impacted by government-imposed restrictions, e.g., the regulation of opening hours. We conclude that future policy measures intending to mitigate the consequences of such shocks should account for this considerable variation in economic hardship.}, language = {en} } @phdthesis{Dressen2021, author = {Dreßen, Sebastian}, title = {Open innovation for manufacturing technologies}, doi = {10.25932/publishup-51438}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-514384}, school = {Universit{\"a}t Potsdam}, pages = {VIII, 141}, year = {2021}, abstract = {This paper-based dissertation aims to contribute to the open innovation (OI) and technology management (TM) research fields by investigating their mechanisms, and potentials at the operational level. The dissertation connects the well-known concept of technology management with OI formats and applies these on specific manufacturing technologies within a clearly defined setting. Technological breakthroughs force firms to continuously adapt and reinvent themselves. The pace of technological innovation and their impact on firms is constantly increasing due to more connected infrastructure and accessible resources (i.e. data, knowledge). Especially in the manufacturing sector it is one key element to leverage new technologies to stay competitive. These technological shifts call for new management practices. TM supports firms with various tools to manage these shifts at different levels in the firm. It is a multifunctional and multidisciplinary field as it deals with all aspects of integrating technological issues into business decision-making and is directly relevant to a number of core business processes. Thus, it makes sense to utilize this theory and their practices as a foundation of this dissertation. However, considering the increasing complexity and number of technologies it is not sufficient anymore for firms to only rely on previous internal R\&D and managerial practices. OI can expanse these practices by involving distributed innovation processes and accessing further external knowledge sources. This expansion can lead to an increasing innovation performance and thereby accelerate the time-to-market of technologies. Research in this dissertation was based on the expectations that OI formats will support the R\&D activities of manufacturing technologies on the operational level by providing access to resources, knowledge, and leading-edge technology. The dissertation represents uniqueness regarding the rich practical data sets (observations, internal documents, project reviews) drawn from a very large German high-tech firm. The researcher was embedded in an R\&D unit within the operational TM department for manufacturing technologies. The analyses include 1.) an exploratory in-depth analysis of a crowdsourcing initiative to elaborate the impact on specific manufacturing technologies, 2.) a deductive approach for developing a technology evaluation score model to create a common understanding of the value of selected manufacturing technologies at the operational level, and 3.) an abductive reasoning approach in form of a longitudinal case study to derive important indicator for the in-process activities of science-based partnership university-industry collaboration format. Thereby, the dissertation contributed to research and practice 1.) linkages of TM and OI practices to assimilate technologies at the operational level, 2.) insights about the impact of CS on manufacturing technologies and a related guideline to execute CS initiatives in this specific environment 3.) introduction of manufacturing readiness levels and further criteria into the TM and OI research field to support decision-makers in the firm in gaining a common understanding of the maturity of manufacturing technologies and, 4.) context-specific important indicators for science based university-industry collaboration projects and a holistic framework to connect TM with the university-industry collaboration approach The findings of this dissertation illustrate that OI formats can support the acceleration of time-to-market of manufacturing technologies and further improve the technical requirements of the product by leveraging external capabilities. The conclusions and implications made are intended to foster further research and improve managerial practices to evolve TM into an open collaborative context with interconnectivities between all internal and external involved technologies, individuals and organizational levels.}, language = {en} } @phdthesis{Eydam2021, author = {Eydam, Ulrich}, title = {Essays on Macroeconomics}, school = {Universit{\"a}t Potsdam}, pages = {161}, year = {2021}, abstract = {This dissertation consists of four self-contained papers. Each paper deals with a specific macroeconomic question. The first paper assesses the distributional implications of environmental policies from a general equilibrium macroeconomic perspective. I develop a New-Keynesian model with several types of uncertainties and frictions that incorporates liquidity constrained households. The model is calibrated to match the German economy and the numerical results show that climate policy instruments can be associated with regressive welfare effects. Furthermore, the analysis shows that these effects can be mitigated through an appropriate revenue recycling scheme. The second paper deals with short-run inequality dynamics within a real business cycle model. An empirical evaluation shows that the cyclical components of income inequality, the capital share and real GDP are correlated. We develop tractable representation of common inequality indicators in the general equilibrium model and show that the observed pattern is driven by innovations in the capital share. A Bayesian estimation of the model for the United States with data for the period 1948 to 2017 indicates that the model provides a reasonable fit for the data and successfully replicates the observed pattern of cyclical correlations. The third paper empirically examines the effects of banking regulation on the risk-relationship between sovereigns and banks. Based on a comprehensive data set of the European banking sector, we find that the implementation of the novel European banking regulation framework significantly contributed to a weakening of the risk-link between sovereigns and banks.The fourth paper empirically examines the role of institutional experience for institutional development in transition economies. To capture institutional experience, we develop a novel index, based on historical country records. The results of cross-sectional and panel estimations suggest that institutional experience helps to explain the divergent economic and institutional development in transition economies after the dissolution of the Soviet Union.}, language = {de} } @phdthesis{AbuJarour2021, author = {AbuJarour, Safa'a}, title = {Digital inclusion}, doi = {10.25932/publishup-51053}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-510535}, school = {Universit{\"a}t Potsdam}, pages = {217}, year = {2021}, abstract = {In this thesis, we tackle two social disruptions: recent refugee waves in Germany and the COVID-19 pandemic. We focus on the use of information and communication technology (ICT) as a key means of alleviating these disruptions and promoting social inclusion. As social disruptions typically lead to frustration and fragmentation, it is essential to ensure the social inclusion of individuals and societies during such times. In the context of the social inclusion of refugees, we focus on the Syrian refugees who arrived in Germany as of 2015, as they form a large and coherent refugee community. In particular, we address the role of ICTs in refugees' social inclusion and investigate how different ICTs (especially smartphones and social networks) can foster refugees' integration and social inclusion. In the context of the COVID-19 pandemic, we focus on the widespread unconventional working model of work from home (WFH). Our research here centers on the main constructs of WFH and the key differences in WFH experiences based on personal characteristics such as gender and parental status. We reveal novel insights through four well-established research methods: literature review, mixed methods, qualitative method, and quantitative method. The results of our research have been published in the form of eight articles in major information systems venues and journals. Key results from the refugee research stream include the following: Smartphones represent a central component of refugee ICT use; refugees view ICT as a source of information and power; the social connectedness of refugees is strongly correlated with their Internet use; refugees are not relying solely on traditional methods to learn the German language or pursue further education; the ability to use smartphones anytime and anywhere gives refugees an empowering feeling of global connectedness; and ICTs empower refugees on three levels (community participation, sense of control, and self-efficacy). Key insights from the COVID-19 WFH stream include: Gender and the presence of children under the age of 18 affect workers' control over their time, technology usefulness, and WFH conflicts, while not affecting their WFH attitudes; and both personal and technology-related factors affect an individual's attitude toward WFH and their productivity. Further insights are being gathered at the time of submitting this thesis. This thesis contributes to the discussion within the information systems community regarding how to use different ICT solutions to promote the social inclusion of refugees in their new communities and foster an inclusive society. It also adds to the growing body of research on COVID-19, in particular on the sudden workplace transformation to WFH.

Keine der bisher vorliegenden Arbeiten legt ihren Fokus auf die Zusammenarbeit von Wissenschaftler:innen in Forschungsteams, obwohl wissenschaftliche Zusammenarbeit ein weitgehend unerforschtes Gebiet ist. Dies verwundert insofern, da gerade innovative und komplexe Aufgaben, wie sie im Bereich der Forschung bestehen, das kreative Potenzial Einzelner sowie eine gut funktionierende Kooperation der einzelnen Individuen ben{\"o}tigen. Die Zusammenarbeit von Wissenschaftler:innen in den AUF findet in einem kompetitiven Umfeld statt. Einerseits stehen die AUF auf Organisationsebene im Wettbewerb zueinander und konkurrieren um Forschungsgelder und wissenschaftliches Personal. Andererseits ist die kompetitive Einwerbung von Drittmitteln f{\"u}r Wissenschaftler:innen essentiell, um Leistungen, gemessen an hochrangigen Publikationen und Drittmittelquoten, f{\"u}r die eigene Karriere zu erbringen. Ein zunehmender Anteil an Drittmittelfinanzierung in den Einrichtungen hat zudem Auswirkungen auf die Personalpolitik und die Anzahl befristeter Arbeitsverh{\"a}ltnisse. Gleichzeitig wird Forschungsf{\"o}rderung h{\"a}ufig an Kollaborationen von Wissenschaftler:innen gekn{\"u}pft und bei Publikationen und Forschungsergebnissen zeigen Studien, dass diese {\"u}berwiegend das Resultat von mehreren Personen sind. Dieses Spannungsfeld zwischen Zusammenarbeit und Wettbewerb wird verst{\"a}rkt durch die fehlenden M{\"o}glichkeiten f{\"u}r den wissenschaftlichen Nachwuchs in der Wissenschaft zu bleiben. Auch wenn die Bundesregierung auf diese Herausforderungen reagiert, muss der Einzelne seinen Weg zwischen Zusammenarbeit und Konkurrenz finden. Zielsetzung dieser Arbeit ist es, nachfolgende Forschungsfragen zu beantworten: 1. Wie k{\"o}nnen naturwissenschaftliche Forschungsteams in AUF charakterisiert werden? 2. Wie agiert die einzelne Forscherin/ der einzelne Forscher im Spannungsfeld zwischen Kooperation und Wettbewerb? 3. Welche Potentiale und Hemmnisse lassen sich auf Individual-, Team- und Umweltebene f{\"u}r eine erfolgreiche Arbeit von Forschungsteams in AUF ausmachen? Um die Forschungsfragen beantworten zu k{\"o}nnen, wurde eine empirische Untersuchung im Mixed Method Design, bestehend aus einer deutschlandweiten Onlinebefragung von 574 Naturwissenschaftler:innen in AUF und qualitativen Interviews mit 122 Teammitgliedern aus 20 naturwissenschaftlichen Forschungsteams in AUF, durchgef{\"u}hrt.

Dieser findet vielmehr in Form kleiner Untergruppen innerhalb der Arbeitsgruppe und vor allem in enger Abstimmung mit der Teamleitung (TL) statt. Als wettbewerbsversch{\"a}rfend werden vor allem organisationale Rahmenbedingungen, wie Befristungen und der Flaschenhals, thematisiert. Die TL nimmt die zentrale Rolle im Team ein, tr{\"a}gt die wissenschaftliche, finanzielle und personelle Verantwortung und muss den Forderungen der Organisation gerecht werden. Promovierende konzentrieren sich fast ausschließlich auf ihre Qualifizierungsarbeit. Bei Postdocs ist ein Spannungsfeld zu erkennen, da sie eigene Projekte und Ziele verfolgen, die neben den Anforderungen der TL bestehen.

Firms are facing an increasingly complex environment and highly complex product and service landscapes that often require multiple organizations to collaborate for innovation and offerings. Public-private partnerships that are targeted at supporting this have been introduced by policy-makers in the recent past. One example for such a partnership is the European Institute of Innovation and Technology (EIT) with multiple Knowledge and Innovation Communities (KICs). The EIT has been initiated by the European Commission in 2008 with the ambition of addressing grand societal challenges, driving innovativeness of European companies, and supporting systemic change. The resulting network organizations are managed similarly to corporations with managers, boards, and firm-like governance structures. EIT Digital as one of the EIT KICs are a central case of this work. Research in this dissertation was based on the expectation that corporate foresight activities will increasingly be embedded in such interorganizational settings and a) can draw on such settings for the benefit of themselves and b) may contribute to shared visions, trust building and planning in these network organizations. In this dissertation the EIT Digital (formerly EIT ICT Labs) is a central case, supplemented with insights from three additional cases. I draw on the rich theoretical understanding of the resource-based view, dynamic capabilities, and particularly the relational view to further the discussion in the field of corporate foresight—defined as foresight in organizations in contrast to foresight with a macro-economical perspective—towards a relational understanding. Further, I use and revisit Rohrbeck's Maturity Model for the Future Orientation of Firms as conceptual frame for corporate foresight in interorganizational settings. The analyses—available as four individual publications complemented by on additional chapter—are designed as exploratory case studies based on multiple data sources including an interview series with 49 persons, two surveys (N=54, n=20), three supplementary interviews, access to key documents and presentations, and observation through participation in meetings and activities of the EIT Digital. This research setting allowed me to contribute to corporate foresight research and practice by 1) integrating relational constructs primarily drawn from the relational view and dynamic capabilities research into the corporate foresight research stream, 2) exploring and understanding capabilities that are required for corporate foresight in interorganizational and networked organizations, 3) discussing and extending the Maturity Model for network organizations, and 4) to support individual organizations to tie their foresight systems effectively to networked foresight systems.}, language = {en} } @phdthesis{Doering2019, author = {D{\"o}ring, Matthias}, title = {The public encounter}, doi = {10.25932/publishup-50227}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-502276}, school = {Universit{\"a}t Potsdam}, pages = {xi, 115}, year = {2019}, abstract = {This thesis puts the citizen-state interaction at its center. Building on a comprehensive model incorporating various perspectives on this interaction, I derive selected research gaps. The three articles, comprising this thesis, tackle these gaps. A focal role plays the citizens' administrative literacy, the relevant competences and knowledge necessary to successfully interact with public organizations. The first article elaborates on the different dimensions of administrative literacy and develops a survey instrument to assess these. The second study shows that public employees change their behavior according to the competences that citizens display during public encounters. They treat citizens preferentially that are well prepared and able to persuade them of their application's potential. Thereby, they signal a higher success potential for bureaucratic success criteria which leads to the employees' cream-skimming behavior. The third article examines the dynamics of employees' communication strategies when recovering from a service failure. The study finds that different explanation strategies yield different effects on the client's frustration. While accepting the responsibility and explaining the reasons for a failure alleviates the frustration and anger, refusing the responsibility leads to no or even reinforcing effects on the client's frustration. The results emphasize the different dynamics that characterize the nature of citizen-state interactions and how they establish their short- and long-term outcomes.}, language = {en} } @phdthesis{Tuebbicke2020, author = {T{\"u}bbicke, Stefan}, title = {Essays on start-up subsidies for the unemployed and methods for causal inference}, doi = {10.25932/publishup-47793}, school = {Universit{\"a}t Potsdam}, pages = {191}, year = {2020}, abstract = {This thesis offers new insights on the effects of Start-Up Subsidies (SUS) for unemployed individuals as a special kind of active labor market program (ALMP) that aims to re-integrate individuals into the labor market via the route of self-employment.

PSM aims to achieve balance in terms of observed characteristics by matching participants with at least one comparable non-participant in terms of their probability to receive the treatment. This estimation strategy is valid as long as all relevant characteristics that explain selection patterns into treatment are observed and included in the estimation of the propensity score. To make our analysis as credible as possible, we control for a large vector of characteristics as observed through the combination of rich administrative data from the Federal Employment Agency as well as through survey data. Chapters two to four of this thesis puts special emphasis on aspects regarding (the evaluation of) SUS programs that have received no or only limited attention thus far. The first aspect relates to the interplay of institutional details of the program and its effectiveness. So far, relatively little is known about the importance of SUS program features such as the duration of support. Second, there is no experimental benchmark evaluation of SUS available and thus, the reliability of non-experimental estimation techniques such as PSM is of crucial importance as estimates are biased when relevant confounders are omitted from the analysis. Third, there may be potentially detrimental effects of transitioning into (relatively risky) self-employment on subjective well-being among subsidized founders out of unemployment. These were to remain undetected if the analysis would focus exclusively on labor market outcomes of participants. The results indicate positive long-term effects of SUS participation on employment and earnings among participants. These effects are substantially larger than what estimated before the reform, indicating room for improvement in program design via changes in institutional details. Moreover, non-experimental estimates of treatment effects are remarkably robust to hidden confounding. Regarding subjective well-being, this thesis finds a positive long-run impact on job satisfaction and a detrimental effect on satisfaction with social security. The latter appears to be driven by adverse effects on social insurance contributions. In chapter five, a novel automated covariate balancing technique for the estimation of causal effects in the context of continuous treatments is derived and assessed regarding its performance compared to other (automated) balancing techniques. Although binary research designs that only differentiate between participants and non-participants of some treatment remain the most-common case in empirical practice, many applications can be adapted to include continuous treatments as well. Often, this will allow for more meaningful estimates of causal effects in order to further improve the design of programs. In the context of SUS, one may further investigate the effects of the size of monetary support or its duration on participants' labor market outcomes. Both Monte-Carlo investigations and analysis of two well-known datasets suggests superior performance of the proposed Entropy Balancing for continuous treatments (EBCT) compared to other existing estimation strategies.}, language = {en} } @phdthesis{Benter2020, author = {Benter, Christine}, title = {Wert und Nutzenstiftung in der Medizin}, school = {Universit{\"a}t Potsdam}, pages = {235}, year = {2020}, abstract = {Zufriedenheitsanalysen durch Patientenbefragungen, wie in diesem Fall der neu entwickele und getestet Fragebogen (HNO-PROM), haben drei S{\"a}ulen.

Large organizations therefore increasingly recognize employees as a significant factor and critical source of innovation. Several studies assert the fact that every employee has to offer certain skills and knowledge and can contribute to innovation. Hence, every employee has a certain 'entrepreneurial potential'. This potential can be expressed in the form of entrepreneurial behaviour and can occur in many ways, from monopersonal innovation championing to several small scale contributions, where several individuals team up for innovation. To support entrepreneurial behaviour of their employees, large organizations increasingly rely on Corporate Entrepreneurship. They set up organizational structures and venturing units, offer vehicles and tools to their employees to be more entrepreneurial. The evolvement of new tools and technologies thereby allow for new ways of employee involvement, also allowing for more radical innovation to be developed collaboratively. Yet, many of such offerings fail to achieve the desired outcome. While some employees immediately opt-in for innovation, others do not and their entrepreneurial potential remains untapped. This research explores how large organizations can better support their employees to express their entrepreneurial potential, thus moving from non-entrepreneurial behaviour or not wanting to be involved, to actually expressing entrepreneurial behaviour. The underlying research therefore is two-fold. While focusing on the individual level and the entrepreneurial behaviour of employees, this research also takes the organizational perspective into account in order to identify how non-entrepreneurial behaviour can be stimulated towards entrepreneurial behaviour. Using an empirical qualitative research design based on pragmatism and abduction, data is collected by means of qualitative interviews as well as a longitudinal use case setting. Grounded theory is then applied for analysis and sense making. The main outcome is a theoretical model of why employees are expressing or not expressing their entrepreneurial potential and how non-expression can potentially be triggered towards entrepreneurial behaviour. The results indicate that there is no one-size-fits all model of Corporate Entrepreneurship. This research therefore argues that organizations can achieve higher levels of entrepreneurial behaviour when addressing employees differently. By developing a theoretical model as well as suggestions of how this model can be applied in practice, this research contributes to theory and practice alike.

It is defined as the 'architecture of the firm's value creation, delivery and appropriation mechanisms' (Foss \& Saebi, 2018, p. 5). The architecture is characterized by complex functional interrelations between activities that are conducted by various actors, some within and some outside of the firm. In other words, a firm's value architecture is embedded within a wider system of actors that all contribute to the output of the value architecture. The question of what drives innovation within this system and how the firm can shape and navigate this innovation is an essential question within innova- tion management research. This dissertation is a compendium of four individual research articles that examine how the design of a firm's value architecture can fa- cilitate system-wide innovation in the context of Artificial Intelligence and Block- chain Technology. The first article studies how firms use Blockchain Technology to design a governance infrastructure that enables innovation within a platform ecosystem. The findings propose a framework for blockchain-enabled platform ecosystems that address the essential problem of opening the platform to allow for innovation while also ensuring that all actors get to capture their share of the value. The second article analyzes how German Artificial Intelligence startups design their business models. It identifies three distinct types of startup with dif- ferent underlying business models. The third article aims to understand the role of a firm's value architecture during the socio-technical transition process of Arti- ficial Intelligence. It identifies three distinct ways in which Artificial Intelligence startups create a shared understanding of the technology. The last article exam- ines how corporate venture capital units configure value-adding services for their venture portfolios. It derives a taxonomy of different corporate venture capital types, driven by different strategic motivations. Ultimately, this dissertation provides novel empirical insights into how a firm's value architecture determines it's role within a wider system of actors and how that role enables the firm to facilitate innovation.

Building on a comprehensive model incorporating various perspectives on this interaction, I derive selected research gaps. The three articles, comprising this thesis, tackle these gaps. A focal role plays the citizens' administrative literacy, the relevant competences and knowledge necessary to successfully interact with public organizations. The first article elaborates on the different dimensions of administrative literacy and develops a survey instrument to assess these. The second study shows that public employees change their behavior according to the competences that citizens display during public encounters. They treat citizens preferentially that are well prepared and able to persuade them of their application's potential. Thereby, they signal a higher success potential for bureaucratic success criteria which leads to the employees' cream-skimming behavior. The third article examines the dynamics of employees' communication strategies when recovering from a service failure. The study finds that different explanation strategies yield different effects on the client's frustration. While accepting the responsibility and explaining the reasons for a failure alleviates the frustration and anger, refusing the responsibility leads to no or even reinforcing effects on the client's frustration.

Limited resources, missing expertise and absolute uncertainty call entrepreneurs to strongly rely on their cognition in searching for a promising BM. However, as prior studies have examined cognitive search activities in isolation and neglected cognitive differences, explanations of how cognitive factors affect the BM process and outcomes are thus far insufficient. Addressing the overall question of how BMs emerge, the dissertation contributes to the cognitive perspective in entrepreneurship and BM research. Building on the dual-process theory from cognitive psychology, the micro-foundations of managerial decision-making and insights from framing literature, this dissertation explicitly investigates the impacts of different cognitive dispositions, search activities and visual framing effects. The core assumption is that cognitive dispositions and entrepreneurs' searches for information determine their BM decision-making. Furthermore, BM visualisations have become popular instruments with which to explain and manage today's complex business interactions. As they abstract from reality, they can also unfold impacts on the cognitive processes. This dissertation offers new explanations to these aspects and consists of three studies and one reflective article. The first study explores the impacts of differences in search activities and cognitive dispositions in a qualitative study with 70 entrepreneurship students. The second qualitative study explores the cognitive impacts of 103 BM visualisations. Third, a quantitative PLS-SEM experiment with 197 entrepreneurs illuminates the link between BM visualisations and cognition. The reflective article expresses the results' meaning for the teaching of BMs. In sum, the studies have resulted in a new theory of stabilising factors explaining how cognitive dispositions, search activities and visual framing determine entrepreneurs' decisions to imitate or deviate from existing BMs. It indicates that the decision depends on the context-dependent strategic orientation and cognitive disposition-dependent cognitive safety, that is the correspondence between characteristics of cognitive dispositions and search activities. Moreover, the studies identified five visual framing effects that are independent of cognitive dispositions and prior experiences. This provides fertile contributions to the literature on BM methods and how BM visualisations affect decisions. Most importantly, BM visualisations provide an emotionally stabilising function to rational entrepreneurs, a cognitively stabilising function to experiential participants and do not affect indifferent participants in general.}, language = {en} } @phdthesis{Fawaz2019, author = {Fawaz, Emadeldin}, title = {The interactive effect of visionary leadership and leader prototypicality on team outcomes}, school = {Universit{\"a}t Potsdam}, pages = {134}, year = {2019}, abstract = {A new model that links visionary leadership with team performance is postulated. It is proposed that leader prototypicality will negatively moderate the effect of visionary leadership on team goal monitoring and performance. This model underlines that teams will compensate for the less prototypicality of a visionary leader by engaging in more goal monitoring, which is a process that is conducive to team performance. A field study included 60 teams, 180 individuals, and 60 team leaders was conducted in Egypt. Parameters were collected on the individual level. Aggregation measures (rwg, ICC1 \& ICC2) were acceptable and the averages were calculated for each team. The proposed three-factor model exhibited a reasonable fit to the data, χ2(130) = 259.93, p-value0.01; CFI = 0.90; and RMSEA = 0.13). The hypothesized negative moderation effect of leader prototypicality on the relationship between visionary leadership and team goal monitoring was statistically significant (-0.16; s.e.= 0.06; t = -3.13; p <0.01; 95\% CI: -0.31, -0.07). Results showed a significant index of moderated mediation (-0.07; s.e.= 0.05; 95\% CI: -0.20, -0.01). As predicted, the indirect effect of visionary leadership on team performance mediated by team goal monitoring was more strongly positive when leader prototypicality was low (b = 0.27; s.e.= 0.16; 95\% CI: 0.04, 0.68), rather than high (b = 0.13; s.e.= 0.10; 95\% CI: 0.01, 0.45).

Second, this dissertation provides a contribution toward overcoming the fragmentation in the leadership literature by desegregating the literature on visionary leadership and leader-team prototypicality.

The analysis mainly relates to the class of incomplete-markets models but covers different research topics. The first paper deals with the distributional effects of financial integration for developing countries. Based on a simple heterogeneous-agent approach, it is shown that capital owners experience large welfare losses while only workers moderately gain due to higher wages. The large welfare losses for capital owners contrast with the small average welfare gains from representative-agent economies and indicate that a strong opposition against capital market opening has to be expected. The second paper considers the puzzling observation of capital flows from poor to rich countries and the accompanying changes in domestic economic development. Motivated by the mixed results from the literature, we employ an incomplete-markets model with different types of idiosyncratic risk and borrowing constraints. Based on different scenarios, we analyze under what conditions the presence of financial market imperfections contributes to explain the empirical findings and how the conditions may change with different model assumptions. The third paper deals with the interplay of incomplete information and financial market imperfections in an incomplete-markets economy. In particular, it analyzes the impact of incomplete information about idiosyncratic income shocks on aggregate saving. The results show that the effect of incomplete information is not only quantitatively substantial but also qualitatively ambiguous and varies with the influence of the income risk and the borrowing constraint. Finally, the fourth paper analyzes the influence of different types of fiscal rules on the response of key macroeconomic variables to a government spending shock. We find that a strong temporary increase in public debt contributes to stabilizing consumption and leisure in the first periods following the change in government spending, whereas a non-debt-intensive fiscal rule leads to a faster recovery of consumption, leisure, capital and output in later periods. Regarding optimal debt policy, we find that a debt-intensive fiscal rule leads to the largest aggregate welfare benefit and that the individual welfare gain is particularly high for wealth-poor agents.}, language = {en} } @phdthesis{Vorholt2019, author = {Vorholt, Dominik}, title = {Konkurrenzausschluss bei deutschen Wirtschaftsverb{\"a}nden}, publisher = {Lit}, address = {Berlin}, isbn = {978-3-64314-296-2}, school = {Universit{\"a}t Potsdam}, pages = {231}, year = {2019}, abstract = {Die deutschen Wirtschaftsverb{\"a}nde geraten zunehmend unter Konkurrenzdruck.

For this reason, how to ask for something in order to increase people's willingness to fulfill such requests is one of the most important question for many people working in various different fields of responsibility such as charitable giving, marketing, management or policy making. This dissertation consists of four chapters that deal with the effects of small changes in the decision-making environment on altruistic decision-making and compliance behavior. Most notably, written communication as an influencing factor is the focus of the first three chapters. The starting point was the question how to devise a request in order to maximize its chance of success (Chapter 1). The results of the first chapter originate the ideas for the second and third chapter. Chapter 2 analyzes how communication by a neutral third-party, i.e. a text from the experimenters that either reminds potential benefactors of their responsibility or highlights their freedom of choice, affects altruistic decision-making. Chapter 3 elaborates on the effect of thanking people in advance when asking them for help. While being not as closely related to the other chapters as the three first ones are, the fourth chapter deals as well with the question how compliance (here: compliance with norms and rules) is affected by subtle manipulations of the environment in which decisions are made. This chapter analyzes the effect of default settings in a tax return on tax compliance. In order to study the research questions outlined above, controlled experiments were conducted. Chapter 1, which analyzes the effect of text messages on the decision to give something to another person, employs a mini-dictator game. The recipient sends a free-form text message to the dictator before the latter makes a binary decision whether or not to give part of her or his endowment to the recipient. We find that putting effort into the message by writing a long note without spelling mistakes increases dictators' willingness to give. Moreover, writing in a humorous way and mentioning reasons why the money is needed pays off. Furthermore, men and women seem to react differently to some message categories. Only men react positively to efficiency arguments, while only women react to messages that emphasize the dictator's power and responsibility. Building on this last result, Chapter 2 attempts to disentangle the effect of reminding potential benefactors of their responsibility for the potential beneficiary and the effect of highlighting their decision power and freedom of choice on altruistic decision-making by studying the effects of two different texts on giving in a dictator game. We find that only men react positively to a text that stresses their responsibility for the recipient by giving more to her or him, whereas only women seem to react positively to a text that emphasizes their decision power and freedom of choice. Chapter 3 focuses on the compliance with a request. In the experiment, participants are asked to provide a detailed answer to an open question. Compliance is measured by the effort participants spend on answering the question. The treatment variable is whether or not they see the text "thanks in advance." We find that participants react negatively by putting less effort into complying with the request in response to the phrase "thanks in advance." Chapter 4 studies the effect of prefilled tax returns with mostly inaccurate default values on tax compliance. In a laboratory experiment, participants earn income by performing a real-effort task and must subsequently file a tax return for three consecutive rounds. In the main treatment, the tax return is prefilled with a default value, resulting from participants' own performance in previous rounds, which varies in its relative size. The results suggest that there is no lasting effect of a default value on tax honesty, neither for relatively low nor relatively high defaults. However, participants who face a default that is lower than their true income in the first round evade significantly and substantially more taxes in this round than participants in the control treatment without a default.}, language = {en} } @phdthesis{Trifonov, author = {Trifonov, Stefan}, title = {Diving Deeper into the Activities and Goals in the Entrepreneurial Process of Internet-enabled Startups}, series = {an activity-based Perspective in the Context of Accelerator Programs}, journal = {an activity-based Perspective in the Context of Accelerator Programs}, school = {Universit{\"a}t Potsdam}, language = {en} } @phdthesis{Weber2019, author = {Weber, Marie-Christin}, title = {Performance Enhancing Strategies in Different Negotiation Phases}, publisher = {Kovac}, address = {Hamburg}, isbn = {978-3-339-10946-0}, school = {Universit{\"a}t Potsdam}, pages = {78}, year = {2019}, abstract = {The present dissertation investigates profit-maximizing behavior in different phases of the negotiation process. Over the last decades, research dealt in detail with behavior of negotiation actors with the aim of identifying performance enhancing factors. The majority of those studies focused on behavior within the main negotiation phase. This work, however, considers phases which are, so far, underrepresented in research but show an impact on the negotiation process and outcome. Those phases are the pre-negotiation, the first offer, and the main negotiation phase which is further divided by breaks into several rounds. Within these phases, traits of behavior are analyzed that can be used strategically in order to impact the negotiation outcome. The dissertation contains three papers, each one dealing with a specific strategy within one phase. The first paper investigates communication behavior in the pre-negotiation phase. Content analysis of a negotiation experiment shows that the employment of positive communication elements such as the generation of enthusiasm for an upcoming project results in an increase of agreements on entering a negotiation and also leads to a higher willingness to make concessions. The second paper explores the impact of a semantic first anchor, which does not contain a specific number but only gives a numerical direction, on the opponent's concession behavior and the final outcome. By means of two scenario-based questionnaires and a negotiation experiment it is demonstrated that semantic offers reveal an anchoring effect and lead to better negotiation outcomes. The third paper deals with the introduction of breaks and their effect on the following negotiation process. Therefore, content and outcome of another negotiation experiment are investigated. The analysis shows that breaks evoke a dominant impression but can negatively impact the atmosphere and thereby also the outcome. Finally, the gathered insights are brought together and discussed.

While the socio-technical change required for this transition is well discussed in the academic literature, the economics that go along with it are often reduced to a cost-benefit perspective of climate policy measures. By investigating climate change mitigation as a coordination problem, this thesis offers a novel perspective: It integrates the economic and the socio-technical dimension and thus allows to better understand the opportunities of a sustainability transition in Europe. First, a game theoretic framework is developed to illustrate coordination on green or brown investment from an agent perspective. A model based on the coordination game "stag hunt" is used to discuss the influence of narratives and signals for green investment as a means to coordinate expectations towards green growth. Public and private green investment impulses - triggered by credible climate policy measures and targets - serve as an example for a green growth perspective for Europe in line with a sustainability transition. This perspective also embodies a critical view on classical analyses of climate policy measures. Secondly, this analysis is enriched with empirical results derived from stakeholder involvement. In interviews and with a survey among European insurance companies, coordination mechanisms such as market and policy signals are identified and evaluated by their impact on investment strategies for green infrastructure. The latter, here defined as renewable energy, electricity distribution and transmission as well as energy efficiency improvements, is considered a central element of the transition to a low-carbon society. Thirdly, this thesis identifies and analyzes major criticisms raised towards stakeholder involvement in sustainability science. On a conceptual level, different ways of conducting such qualitative research are classified. This conceptualization is then evaluated by scientists, thereby generating empirical evidence on ideals and practices of stakeholder involvement in sustainability science. Through the combination of theoretical and empirical research on coordination problems, this thesis offers several contributions: On the one hand, it outlines an approach that allows to assess the economic opportunities of sustainability transitions. This is helpful for policy makers in Europe that are striving to implement climate policy measures addressing the targets of the Paris Agreement as well as to encourage a shift of investments towards green infrastructure. On the other hand, this thesis enhances the stabilization of the theoretical foundations in sustainability science.

As they shift from products to (service) solutions, manufacturing companies pursue new strategic direction, inter alia, by extensively employing service business development activities. The objective of this dissertation is to investigate the considerable (re-)emerging stream of service business development by providing vital insights for academia and management into important focus areas that have hardly, if at all, been (empirically) investigated in the existing literature before. Therefore, these findings can be vital to informing a differentiation in current and future marketing strategies in business practice. First of all, this dissertation focuses on the extent to which service business development is transposed into business practice. Because scarce empirical-quantitative research has studied the current state of service business development across various industry and market sectors, this study analyzes a unique, manually collected dataset of 266 (product and service) business development activities. In so doing, this investigation contributes to literature by presenting a comprehensive, industry-wide status quo and trend report of service business development in practice. Furthermore, given the surprisingly limited scientific attention paid to the question of how service business development is strategically configured and further applied to different environmental circumstances, this dissertation provides comprehensive theoretical and practical implications by analyzing in detail a sample of 137 service business developments of 66 product-oriented companies. Lastly, manufacturers are recognizing that service-oriented value creation is moving toward a more collaborative process of co-creation as a promising measure to achieve competitive advantage, and even more as an appropriate response to complex business environments. Thus, an increasing number of companies around the world have recently introduced business models related to access-based services such as car-, scooter-, and bike-sharing systems. But despite the considerable advantages of access-based services as an alternative to ownership, these companies are now seeing that consumer adoption and (re-)usage rates remain insufficient. Owing to the lack of general and cross-national scientific knowledge, the purpose of this dissertation continues to explore which factors impede diffusion of related service business development activities from a consumer perspective and what kind of differences can be established between countries. Consequently, with a total of 1,443 participants, a cross-national survey was carried out in three countries, i.e., the United States, Germany, and China, to measure a vast number of different adoption barriers derived from a developed integrated framework that combines established theories within innovation and adoption behavior research.}, language = {en} } @phdthesis{Knoepfle2018, author = {Kn{\"o}pfle, Timo Andreas}, title = {Methoden der Datenerhebung in der Verhandlungsforschung}, series = {Schriftenreihe zum Verhandlungsmanagement ; 8}, journal = {Schriftenreihe zum Verhandlungsmanagement ; 8}, publisher = {Kovac}, address = {Hamburg}, isbn = {978-3-339-10512-7}, pages = {296}, year = {2018}, abstract = {Valide generierte Daten aus Verhandlungen bilden die Grundlage zum Ergr{\"u}nden von Art und Umfang verschiedener Einflussfaktoren auf den Verhandlungsprozess und das Verhandlungsergebnis.

Dies trifft insbesondere auch auf die duale kaufm{\"a}nnische Berufsausbildung zu. Galt sie vor einigen Jahren noch als ein m{\"o}glicher Ausbildungsweg f{\"u}r leistungsstarke Sch{\"u}ler/-innen, pr{\"a}ferieren diese heute zum großen Teil das Studium. Die wachsende Anzahl an Studienabbrechern belegt jedoch, dass dadurch auch Potenzial verloren geht, weil sich Jugendliche mit dem Studium f{\"u}r einen Ausbildungsweg entscheiden, der f{\"u}r sie nicht geeignet ist. Bisherige Bem{\"u}hungen zur Etablierung alternativer Bildungswege wie zum Beispiel Berufsakademien weisen zwar Erfolge auf, basieren jedoch auf einem Konzept, das sich ausschließlich am Bedarf der Wirtschaft orientiert. Es ist jedoch die {\"U}berzeugung der Autorin, dass neue innovative Bildungswege auch die Bed{\"u}rfnisse und Vorstellungen derjenigen ber{\"u}cksichtigen m{\"u}ssen, f{\"u}r die sie entworfen werden. Denn die Generation der heutigen Jugendlichen zeichnet sich dadurch aus, dass sie ein anderes Wertekonzept als ihre Vorg{\"a}ngergenerationen aufweist. Die Dissertation entwickelt daher ein Modell einer wirtschaftsorientierten Ausbildung, welches sich aus unterschiedlichen motivationstheoretischen Elementen ableitet und zugleich die Werte der Generation der heutigen Jugend-lichen ber{\"u}cksichtigt. Es umfasst sowohl die Anreiz-Beitrags-Theorie nach Barnard als auch die Inhalts-Erwartungstheorie nach Vroom. Zudem liegt ein Hauptaugenmerk dieser Arbeit auf der Anpassung der Zwei-Faktoren-Theorie nach Herzberg auf die heutige Zeit. Empirisch basiert die Dissertation auf einem dreistufigen Untersuchungsdesign. Die erste Stufe umfasst eine quantitative Befragung von insgesamt 459 Abiturienten/-innen und 100 Studierenden. In der zweiten Stufe wurden 10 Studieren-de und 12 Abiturienten/-innen qualitativ befragt. Eine Validierung der Ergebnis-se erfolgte in der dritten Stufe mittels Experteninterviews. Das Ziel der empirischen Untersuchung bestand in der {\"U}berpr{\"u}fung von vier Hypothesen als Basis zur Modellableitung: Hypothese H1 - Flexibilit{\"a}t erh{\"o}ht die Attraktivit{\"a}t einer wirtschaftsorientierten Ausbildung: Der Faktor Flexibilit{\"a}t wurde als ein relevanter Motivator f{\"u}r die Wahl eines Ausbildungsweges identifiziert. Jugendliche wollen sich heutzutage nicht sofort bzw. nicht zu fr{\"u}h festlegen m{\"u}ssen. Hypothese H2 - Auslandsaufenthalte erh{\"o}hen die Attraktivit{\"a}t einer wirtschaftsorientierten Ausbildung: Es wurde best{\"a}tigt, dass Auslandsaufenthalte die Attraktivit{\"a}t einer wirtschaftsorientierten Ausbildung steigert, es besteht jedoch eine Reihe von Barrieren, die Jugendliche (obwohl sie den grunds{\"a}tzlichen Vor-teil sehen) davon abhalten, einen Auslandsaufenthalt f{\"u}r sich selbst in Betracht zu ziehen. Hypothese H3 - Das Aufzeigen einer Karriereperspektive erh{\"o}ht die Attraktivit{\"a}t einer wirtschaftsorientierten Ausbildung: F{\"u}r die Generation der heutigen Jugendlichen steht bez{\"u}glich der Wahl ihres Ausbildungsweges die Aussicht auf eine T{\"a}tigkeit im Vordergrund, die ein gesichertes Einkommen und somit ein gutes Leben erm{\"o}glicht und zudem aus ihrer Sicht eine gewisse Sinnhaftigkeit hat. F{\"u}hrungspositionen, in denen auch h{\"o}here Verantwortung {\"u}bernommen wird, strebt nur eine Minderheit an. Hypothese H4 - Zus{\"a}tzliche monet{\"a}re Anreize erh{\"o}hen die Attraktivit{\"a}t einer wirtschaftsorientierten Ausbildung: Verg{\"u}tungsbestandteile werden grunds{\"a}tzlich nicht abgelehnt (das w{\"a}re auch irrational), haben jedoch auch nicht die Anreizfunktion, die ihr auf Basis der Voruntersuchung im Rahmen dieser Arbeit h{\"a}tte unterstellt werden k{\"o}nnen. F{\"u}r die Entscheidungsfindung bez{\"u}glich eines Ausbildungsweges spielen sie nur eine untergeordnete Rolle. Dennoch tr{\"a}gt die Verg{\"u}tung zur Attraktivit{\"a}t eines Ausbildungsweges bei. Basierend auf den zuvor genannten Ergebnissen wurde das Modell einer wirtschaftsorientieren Ausbildung abgeleitet, das sowohl horizontal als auch vertikal flexibel ist. Horizontale Flexibilit{\"a}t ist dadurch gegeben, dass innerhalb eines Ausbildungsjahres unterschiedliche Unternehmen und Branchen kennengelernt werden (Jahr 1 und Jahr 2). Eine Spezialisierung erfolgt erst in den sp{\"a}teren Ausbildungsjahren. Durch die M{\"o}glichkeit, nach jedem Ausbildungsjahr mit einem Abschluss ins Berufsleben zu wechseln und die Ausbildung gegebenenfalls zu einem sp{\"a}teren Zeitpunkt fortzusetzen, ist auch eine vertikale Flexibilit{\"a}t gegeben. Zudem bietet das Modell Studienabbrechern/-innen die M{\"o}glichkeit, im Ausbildungsjahr 2 bzw. 3 in die Ausbildung einzusteigen. Im Jahr 2 und/oder Jahr 3 sind Auslandsaufenthalte integriert. Diese werden fakultativ an-geboten. Bereits ab dem Jahr 1 besteht die M{\"o}glichkeit, Vorbereitungskurse zu belegen. Der hohen Bedeutung der Karriereperspektive wird im abgeleiteten Modell auf mehreren Ebenen Rechnung getragen. So werden nach jedem Ausbildungsjahr anerkannte Abschl{\"u}sse erreicht. W{\"a}hrend diese in den Jahren 1 und 2 mit IHK-Abschl{\"u}ssen gleichzusetzen sind, beginnen ab Jahr 3 die akademischen Graduierungen (Jahr 3 Bachelor, Jahr 4 Master). Die Verg{\"u}tung wird Bestandteil einer wirtschaftsorientierten Ausbildung, wobei ihre H{\"o}he mit Dauer der Ausbildung zunimmt. Da mit der Einf{\"u}hrung des Modells einer wirtschaftsorientierten Ausbildung die {\"U}berwindung von institutionellen Paradigmen und Schranken verbunden sind, erfolgte im Rahmen des Ausblicks der Arbeit eine weitere Expertenbefragung bez{\"u}glich seiner Umsetzbarkeit. Es setzt eine Beweglichkeit von institutioneller Seite voraus (hierbei insbesondere auch von den Kammern), die von der Mehr-zahl der Experten derzeit skeptisch gesehen wird. Die konzeptionelle Ausgestaltung findet grunds{\"a}tzlichen Zuspruch, wobei in einigen Details, zum Beispiel in der Dauer der Ausbildung, noch Kl{\"a}rungsbedarf besteht. Grunds{\"a}tzlich schließen sich die Experten/-innen der Meinung der Autorin an, dass ein Sinneswandel in der deutschen Ausbildungslandschaft gew{\"u}nscht und gefordert wird. Dies betrifft insbesondere auch den kaufm{\"a}nnischen Bereich.

The first paper examines whether and how EFRAG generally fulfills its role in articulating Europe's interests toward the International Accounting Standards Board (IASB). The qualitative data from the conducted interviews reveal that EFRAG influences the IASB's decision making at a very early stage, long before other constituents are officially asked to comment on the IASB's proposals. The second paper uses quantitative data and investigates the formal participation behavior of European constituents that seek to determine EFRAG's voice. More precisely, this paper analyzes the nature of the constituents' participation in EFRAG's due process in terms of representation (constituent groups and geographical distribution) and the drivers of their participation behavior. EFRAG's official decision making process is dominated by some specific constituent groups (such as preparers and the accounting profession) and by constituents from some specific countries (e.g. those with effective enforcement regimes). The third paper investigates in a first step who of the European constituents choose which lobbying channel (participation only at IASB, only at EFRAG, or at both institutions) and unveils in a second step possible reasons for their lobbying choices. The paper comprises quantitative and qualitative data. It reveals that English skills, time issues, the size of the constituent, and the country of origin are factors that can explain why the majority participates only in the IASB's due process.}, language = {en} } @phdthesis{Ullrich2018, author = {Ullrich, Andr{\´e}}, title = {Eigenschaften wandlungsf{\"a}higer Systeme}, publisher = {GITO}, address = {Berlin}, isbn = {978-3-95545-265-0}, school = {Universit{\"a}t Potsdam}, pages = {XIX, 403}, year = {2018}, abstract = {Wandlungsf{\"a}higkeit beschreibt die F{\"a}higkeit eines Systems, proaktiv oder reaktiv Maßnahmen f{\"u}r die Modifikation seiner Eigenschaften schnell und effizient zu entwickeln, umzusetzen und anzuwenden sowie sich proaktiv darauf vorzubereiten, inaktiv zu sein und passiv Einwirkungen aus der Umwelt zu tolerieren.

A variety of institutions and incentives, which are embedded in UI schemes across OECD countries, reflect this attempt. For instance, job seekers entering UI are often provided with personal support through a caseworker. They also face the requirement to regularly submit a minimum number of job applications, which is typically enforced through benefit cuts in the case of non-compliance. Moreover, job seekers may systematically receive information on their re-employment prospects. As a consequence, UI design has become a complex task. Policy makers need to define not only the amount and duration of benefit payments, but also several other choice parameters. These include the intensity and quality of personal support through caseworkers, the level of job search requirements, the strictness of enforcement, and the information provided to unemployed individuals. Causal estimates on how these parameters affect re-employment outcomes are thus central inputs to the design of modern UI systems: how much do individual caseworkers influence the transition out of unemployment? Does the requirement of an additional job application translate into increased job finding? Do individuals behave differently when facing a strict versus mild enforcement system? And how does information on re-employment prospects influence the job search decision? This dissertation proposes four novel research designs to answer this question. Chapters one to three elaborate quasi-experimental identification strategies, which are applied to large-scale administrative data from Switzerland. They, respectively, measure how personal interactions with caseworkers (chapter one), the level of job search requirements (chapter two) and the strictness of enforcement (chapter three) affect re-employment outcomes. Chapter four proposes a structural estimation approach, based on linked survey and administrative data from Germany. It studies how over-optimism on future wage offers affects the decision to search for work, and how the provision of information changes this decision.}, language = {en} } @phdthesis{SarnesNitu2018, author = {Sarnes-Nitu, Juliane}, title = {Mit der Schuldenbremse zu nachhaltigen Staatsfinanzen?}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-413804}, school = {Universit{\"a}t Potsdam}, pages = {294}, year = {2018}, abstract = {The core question of this paper is: Does the debt brake secure fiscal sustainability in Germany? To answer this question, we will first examine the effects of the introduction of the debt brake on the German federal states in the period 2010-16. For this purpose, the observed consolidation performance and the consolidation incentive or pressure experienced by the federal states were evaluated with the help of a scorecard specifically developed for this purpose. Multiple regression analysis was used to analyze how the scorecard factors affect the consolidation performance of the federal states. It found that nearly 90\% of the variation was explained by the independent variables budgetary position, debt burden, revenue growth and pension burden. Thus the debt brake likely played a subordinate role in the 2009-2016 consolidation episode. Subsequently, the data collected in 65 expert interviews was used to analyze the limits of the new fiscal rule, and to determine which potential risks could hinder or prevent the debt brake in the future: municipal debt, FEUs, contingent liabilities in the form of guarantees for financial institutions and pension obligations. The frequently expressed criticism that the debt brake impedes economic growth and public investments is also reviewed and rejected.

The overarching subject is concerned with the relationship between creativity, freedom, and control, considering freedom is also seen as an element of control to manage creativity. Design/methodology/approach - In-depth qualitative data gathered from at two innovative start-ups. Two ethnographic studies were conducted. The data are based on participatory observations, interviews, and secondary sources, each of which included a three months field study and a total of 41 interviews from both organizations. Findings - The thesis provides explanations for the practice of freedom and the control of creativity within organizations and expands the existing theory of neo-normative control. The findings indicate that organizations use complex control systems that allow a high degree of freedom that paradoxically leads to more control. Freedom is a cover of control, which in turn leads to creativity. Covert control even results in the responsibility to be creative outside working hours. Practical implications - Organizations, which rely on creativity might use the results of this thesis. Positive workplace control of creativity provides both freedom and structure for creative work. While freedom leads to organizational members being more motivated and committing themselves more strongly to their and the organization's goals, and a specific structure also helps to provide the requirements for creativity. Originality/value - The thesis provides an insight into an approach to workplace control, which has mostly neglected in creativity research and proposes a modified concept of neo-normative control. It serves to provide a further understanding of freedom for creativity and to challenge the liberal claims of new control forms.}, language = {en} } @phdthesis{Wagner2017, author = {Wagner, Mario}, title = {Industrie 4.0 und demografische Entwicklung aus strukturationstheoretischer Sicht}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-412230}, school = {Universit{\"a}t Potsdam}, pages = {235}, year = {2017}, abstract = {Das Ziel der Arbeit ist die Entwicklung eines heuristischen Bezugsrahmens zur Erkl{\"a}rung der Komplexit{\"a}t im Kontext von Industrie 4.0 und der demografischen Entwicklung aus strukturationstheoretischer Sicht. Dabei sind in Bezug auf die zuk{\"u}nftig zu erwartenden kognitiven Anforderungen an die Besch{\"a}ftigten die Fragen essentiell, vor welchen Herausforderungen Unternehmen bez{\"u}glich der Einstellung und dem Verhalten sowie dem Erfahrungswissen der Besch{\"a}ftigten stehen und welche L{\"o}sungsans{\"a}tze sich im Umgang mit den Herausforderungen in der Praxis bisher als hilfreich erweisen. In Kapitel 1 erfolgt zun{\"a}chst die Beschreibung der Ausgangslage. Es werden die Begriffe Industrie 4.0 und demografische Entwicklung inhaltlich diskutiert und in einen theoretischen Zusammenhang gebracht. In Kapitel 2 erfolgt die theoretische Fundierung der Arbeit. Dabei wird eine strukturationstheoretische Sicht auf Unternehmen als soziotechnische Systeme eingenommen. Durch diese „nicht deterministische" Sichtweise wird ein prozessualer Blick auf den Wandlungsprozess in Unternehmen geschaffen, der es m{\"o}glich macht, die Besch{\"a}ftigten als aktiv handelnde Akteure im Sinne von „organisieren" zur Erkl{\"a}rung m{\"o}glicher Zusammenh{\"a}nge zwischen Industrie 4.0 und der demografischen Entwicklung mit einzubeziehen. Der soziotechnische Systemansatz und die Strukturationstheorie bilden in diesem Sinne den „Kern" des zu entwickelnden heuristischen Bezugsrahmens. Die inhaltliche Gestaltung des theoriebasierten heuristischen Bezugsrahmens erfolgt in Kapitel 3 und Kapitel 4. Kapitel 3 beschreibt ausgew{\"a}hlte Aspekte zuk{\"u}nftiger Anforderungen an die Arbeit, die durch eine systematische Aufbereitung des derzeitigen Forschungsstandes zu Industrie 4.0 ermittelt wurden. Sie bilden die „Gestaltungsgrenzen", innerhalb derer sich je nach betrieblicher Situation unterschiedliche neue oder ge{\"a}nderte Anforderungen an die Besch{\"a}ftigten bei der Gestaltung von Industrie 4.0 ableiten lassen. In Kapitel 4 werden ausgew{\"a}hlte Aspekte menschlichen Handelns am Beispiel {\"a}lterer Besch{\"a}ftigter in Form zweier Schwerpunkte beschrieben. Der erste Schwerpunkt betrifft m{\"o}gliche Einflussfaktoren auf die Einstellung und das Verhalten {\"a}lterer Besch{\"a}ftigter im Wandlungsprozess aufgrund eines vorherrschenden Altersbildes im Unternehmen. Grundlage hierzu bildete die Stigmatisierungstheorie als interaktionistischer Ansatz der Sozialtheorie. Mit dem zweiten Schwerpunkt, den ausgew{\"a}hlten handlungstheoretischen Aspekten der Alternsforschung aus der Entwicklungspsychologie, wird eine Lebensspannenperspektive eingenommen. Inhaltlich werden die komplexit{\"a}tsinduzierten Faktoren, die sich aus handlungstheoretischer Perspektive mit der Adaptation von {\"a}lteren Besch{\"a}ftigten an ver{\"a}nderte {\"a}ußere und pers{\"o}nliche Lebensbedingungen besch{\"a}ftigen, systematisiert. Anschließend wird auf Grundlage der bisherigen theoretischen Vor{\"u}berlegungen ein erster theoriebasierter Bezugsrahmen abgeleitet. Kapitel 5 und Kapitel 6 beschreiben den empirischen Teil, die Durchf{\"u}hrung teilstrukturierter Interviews, der Arbeit. Ziel der empirischen Untersuchung war es, neben der theoretischen Fundierung den theoriebasierten heuristischen Bezugsrahmen um Praxiserfahrungen zu konkretisieren und gegebenenfalls zu erg{\"a}nzen. Hierzu wurde auf Grundlage des theoriebasierten heuristischen Bezugsrahmens mittels teilstrukturierter Interviews das Erfahrungswissen von 23 Experten in pers{\"o}nlichen Gespr{\"a}chen abgefragt. Nachdem in Kapitel 5 die Vorgehensweise der empirischen Untersuchung beschrieben wird, erfolgt in Kapitel 6 die Beschreibung der Ergebnisse aus der qualitativen Befragung. Hierzu werden aus den pers{\"o}nlichen Gespr{\"a}chen zentrale Einflussfaktoren bei der Gestaltung und Umsetzung von Industrie 4.0 im Kontext mit der demografischen Entwicklung analysiert und in die {\"u}bergeordneten Kategorien Handlungskompetenzen, Einstellung/ Verhalten sowie Erfahrungswissen geclustert. Anschließend wird der theoriebasierte heuristische Bezugsrahmen durch die {\"u}bergeordneten Kategorien und Faktoren aus den Expertengespr{\"a}chen konkretisiert und erg{\"a}nzt.

In contrast to traditional ALMP instruments like training measures, wage subsidies, or job creation schemes, which are aimed at reintegrating unemployed individuals into dependent employment, start-up incentives are a fundamentally different approach to ALMP, in that they intend to encourage and help unemployed individuals to exit unemployment by entering self-employment and, thus, by creating their own jobs. In this sense, start-up incentives for unemployed individuals serve not only as employment and social policy to activate job seekers and combat unemployment but also as business policy to promote entrepreneurship.

The main part of the thesis at hand examines the new start-up subsidy ("Gr{\"u}ndungszuschuss") in Germany and consists of four empirical analyses that extend the existing evidence on start-up incentives for unemployed individuals from multiple perspectives and in the following directions: First, it provides the first impact evaluation of the new start-up subsidy in Germany. The results indicate that participation in the new start-up subsidy has significant positive and persistent effects on both reintegration into the labor market as well as the income profiles of participants, in line with previous evidence on comparable German and international programs, which emphasizes the general potential of start-up incentives as part of the broader ALMP toolset. Furthermore, a new innovative sensitivity analysis of the applied propensity score matching approach integrates findings from entrepreneurship and labor market research about the key role of an individual's personality on start-up decision, business performance, as well as general labor market outcomes, into the impact evaluation of start-up incentives. The sensitivity analysis with regard to the inclusion and exclusion of usually unobserved personality variables reveals that differences in the estimated treatment effects are small in magnitude and mostly insignificant. Consequently, concerns about potential overestimation of treatment effects in previous evaluation studies of similar start-up incentives due to usually unobservable personality variables are less justified, as long as the set of observed control variables is sufficiently informative (Chapter 2). Second, the thesis expands our knowledge about the longer-term business performance and potential of subsidized businesses arising from the start-up subsidy program. In absolute terms, the analysis shows that a relatively high share of subsidized founders successfully survives in the market with their original businesses in the medium to long run. The subsidy also yields a "double dividend" to a certain extent in terms of additional job creation. Compared to "regular", i.e., non-subsidized new businesses founded by non-unemployed individuals in the same quarter, however, the economic and growth-related impulses set by participants of the subsidy program are only limited with regard to employment growth, innovation activity, or investment. Further investigations of possible reasons for these differences show that differential business growth paths of subsidized founders in the longer run seem to be mainly limited by higher restrictions to access capital and by unobserved factors, such as less growth-oriented business strategies and intentions, as well as lower (subjective) entrepreneurial persistence. Taken together, the program has only limited potential as a business and entrepreneurship policy intended to induce innovation and economic growth (Chapters 3 and 4). And third, an empirical analysis on the level of German regional labor markets yields that there is a high regional variation in subsidized start-up activity relative to overall new business formation. The positive correlation between regular start-up intensity and the share among all unemployed individuals who participate in the start-up subsidy program suggests that (nascent) unemployed founders also profit from the beneficial effects of regional entrepreneurship capital. Moreover, the analysis of potential deadweight and displacement effects from an aggregated regional perspective emphasizes that the start-up subsidy for unemployed individuals represents a market intervention into existing markets, which affects incumbents and potentially produces inefficiencies and market distortions. This macro perspective deserves more attention and research in the future (Chapter 5).}, language = {en} } @phdthesis{Preuss2018, author = {Preuß, Melanie}, title = {New Perspectives on Negotiation Styles}, series = {Schriftenreihe zum Verhandlungsmanagement}, journal = {Schriftenreihe zum Verhandlungsmanagement}, number = {7}, publisher = {Verlag Dr. Kovač}, address = {Hamburg}, isbn = {978-3-8300-9794-5}, issn = {2365-7898}, pages = {XI, 110}, year = {2018}, abstract = {Companies have a keen interest in developing skilled negotiators in order to improve their negotiation outcome.

It is used as a means to enhance productivity or to gain momentum on the market. The success of introducing new technologies into the organisation relies heavily on user acceptance. Existing explanations like the Diffusion of Innovation Theory (Rogers, 2003) and the Technology Acceptance Model and its extensions (Davis, 1989; Venkatesh and Davis, 1996; Venkatesh and Davis, 2000; Venkatesh, Morris, et al., 2003) do not address the organisational context sufficiently. Their models concentrate on technology adoption in a non-mandatory environment. Furthermore they do not encompass resistance against a new technology. Hence these models cannot be used to analyse the acceptance and usage decision process within organisations. This thesis therefore aims at investigating the organisational dynamics evoked by the introduction of new technologies with regard to acceptance and usage. More precisely it answers the question, whether different organisation types exert varying influences on their members and produce different patterns of acceptance and usage. The groundwork to achieve this insight is the synthesis and extension of different models of technology acceptance and organisational governance. The resulting model describes the development dynamics within an organisation and model combines two perspectives. On one hand the individual level encompasses socio-psychological aspects and individual decision making processes. This perspective is based on the aforementioned theories of individual acceptance, which are extended with different fit theories (Goodhue and Thompson, 1995; Floyd, 1986; Liu, Lee, and Chen, 2011; Parkes, 2013). Furthermore the resistance to new technology is introduced into the analysis as another possible course of action (Patsiotis, Hughes, and Webber, 2012). The organisational perspective on the other hand embeds the individual acceptance and usage decision into a social context. The interaction between organisation members based on the observation of others and the internalisation of social pressure are introduced as determinants of acceptance and usage. Furthermore organisational governance structures moderate this social influence and specify its impact. The relationship between governance and social influence is elaborated through the application of system theory to the organisational context: Actors like change agents or management use governance media (Luhmann, 1997; Fischer, 2009) to intervene in the individual decisions. The effect of these governance media varies with certain attributes of the organisation. Different coordination mechanisms of organisational configurations (Mintzberg, 1979) provide a link to governance media and their connectivity to individual decision processes. In order to demonstrate the feasibility of model a simulation experiment is conducted in AnyLogic. The validity of the model was tested in a sensitivity analysis. The results from the experiment show a specific acceptance and usage pattern. The acceptance is dropping at first due to the initial frustration. It then recovers and is growing in a bounded manner. Since usage is mandatory in an organisation, it is enforced by the management. This leads to a rapid increase of usage at first and stabilises on different levels during the course of the simulation. It was also found that different organisation configurations produce varying outcomes. The bureaucratic organisation enforces the usage better than any other configuration, leading to a higher usage level. However it fails to produce acceptance. The adhocracy on the other hand reaches a higher acceptance level through mutual adjustment. Its downside is the lack of usage. Furthermore the behaviour is not predictable, which can either lead to mostly positive outcomes or the complete break-down of the diffusion process. The simulation shows that organisations have to decide during the introduction of a new technology whether they want high usage rates fast with the risk of failing in the long term or establish a self-enforcing and sustainable diffusion processes which requires more time to be effective.}, language = {de} } @phdthesis{Pfannstiel2017, author = {Pfannstiel, Mario Alexander}, title = {Service Performance Measurement in Expertenorganisationen}, school = {Universit{\"a}t Potsdam}, pages = {266, XXXVI}, year = {2017}, language = {de} } @phdthesis{Mahlstedt2017, author = {Mahlstedt, Robert}, title = {Essays on job search behavior and labor market policies}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-397081}, school = {Universit{\"a}t Potsdam}, pages = {252}, year = {2017}, abstract = {Persistently high unemployment rates are a major threat to the social cohesion in many societies. To moderate the consequences of unemployment industrialized countries spend substantial shares of their GDP on labor market policies, while in recent years there has been a shift from passive measures, such as transfer payments, towards more activating elements which aim to promote the reintegration into the labor market. Although, there exists a wide range of evidence about the effects of traditional active labor market policies (ALMP) on participants' subsequent labor market outcomes, a deeper understanding of the impact of these programs on the job search behavior and the interplay with long-term labor market outcomes is necessary. This allows policy makers to improve the design of labor market policies and the allocation of unemployed workers into specific programs. Moreover, previous studies have shown that many traditional ALMP programs, like public employment or training schemes, do not achieve the desired results. This underlines the importance of understanding the effect mechanisms, but also the need to develop innovative programs that are more effective. This thesis extends the existing literature with respect to several dimensions. First, it analyzes the impact of job seekers' beliefs about upcoming ALMPs programs on the effectiveness of realized treatments later during the unemployment spell. This provides important insights with respect to the job search process and relates potential anticipation effects (on the job seekers behavior before entering a program) to the vast literature evaluating the impact of participating in an ALMP program on subsequent outcomes. The empirical results show that training programs are more effective if the participants expect participation ex ante, while expected treatment effects are unrelated to the actual labor market outcomes of participants. A subsequent analysis of the effect mechanisms shows that job seekers who expect to participate also receive more information by their caseworker and show a higher willingness to adjust their search behavior in association with an upcoming ALMP program. The findings suggest that the effectiveness of training programs can be improved by providing more detailed information about the possibility of a future treatment early during the unemployment spell. Second, the thesis investigates the effects of a relatively new class of programs that aim to improve the geographical mobility of unemployed workers with respect to the job search behavior, the subsequent job finding prospects and the returns to labor market mobility. To estimate the causal impact of these programs, it is exploited that local employment agencies have a degree of autonomy when deciding about the regional-specific policy mix. The findings show that the policy style of the employment agency indeed affects the job search behavior of unemployed workers. Job seekers who are assigned to agencies with higher preferences for mobility programs increase their search radius without affecting the total number of job applications. This shift of the search effort to distant regions leads to a higher probability to find a regular job and higher wages. Moreover, it is shown that participants in one of the subsidy programs who move to geographically distant region a earn significantly higher wages, end up in more stable jobs and face a higher long-run employment probability compared to non-participants. Third, the thesis offers an empirical assessment of the unconfoundedness assumption with respect to the relevance of variables that are usually unobserved in studies evaluating ALMP programs. A unique dataset that combines administrative records and survey data allows us to observe detailed information on typical covariates, as well as usually unobserved variables including personality traits, attitudes, expectations, intergenerational information, as well as indicators about social networks and labor market flexibility. The findings show that, although our set of usually unobserved variables indeed has a significant effect on the selection into ALMP programs, the overall impact when estimating treatment effects is rather small. Finally, the thesis also examines the importance of gender differences in reservation wages that allows assessing the importance of special ALMP programs targeting women. In particular, when including reservation wages in a wage decomposition exercise, the gender gap in realized wages becomes small and statistically insignificant. The strong connection between gender differences in reservation wages and realized wages raises the question how these differences in reservation wages are set in the first place. Since traditional covariates cannot sufficiently explain the gender gap in reservation wages, we perform subgroup analysis to better understand what the driving forces behind this gender gap are.}, language = {en} } @phdthesis{Dirkwinkel2017, author = {Dirkwinkel, Lea}, title = {Trust and fairtrade consumption}, series = {Schriftenreihe Studien zum Konsumentenverhalten ; 77}, journal = {Schriftenreihe Studien zum Konsumentenverhalten ; 77}, publisher = {Kovac}, address = {Hamburg}, isbn = {978-3-8300-9599-6}, school = {Universit{\"a}t Potsdam}, pages = {XX, 235}, year = {2017}, abstract = {Wie h{\"a}ngen Vertrauen, Konsumeinstellungen und Verhalten bez{\"u}glich Fairtrade zusammen?

Nowadays, firms recognize an increasing demand for innovation to keep pace with an ever-growing dynamic worldwide competition. Knowledge is one of the most crucial sources and resource, while until now innovation has been foremost driven by technology. But since the last years, we have been witnessing a change from technology's role as a driver of innovation to an enabler of innovation. Innovative products and services increasingly differentiate through emotional qualities and user experience. These experiences are hard to grasp and require alignment in innovation management theory and practice. This work cares about culture in a broader matter as a source for innovation. It investigates the requirements and fundamentals for "culture-driven innovation" by studying where and how to unlock cultural sources. The research questions are the following: What are cultural sources for knowledge and innovation? Where can one find cultural sources and how to tap into them? The dissertation starts with an overview of its central terms and introduces cultural theories as an overarching frame to study cultural sources for innovation systematically. Here, knowledge is not understood as something an organization owns like a material resource, but it is seen as something created and taking place in practices. Such a practice theoretical lens inheres the rejection of the traditional economic depiction of the rational Homo Oeconomicus. Nevertheless, it also rejects the idea of the Homo Sociologicus about the strong impact of society and its values on individual actions. Practice theory approaches take account of both concepts by underscoring the dualism of individual (agency, micro-level) and structure (society, macro-level). Following this, organizations are no enclosed entities but embedded within their socio-cultural environment, which shapes them and is also shaped by them. Then, the first article of this dissertation acknowledges a methodological stance of this dualism by discussing how mixed methods support an integrated approach to study the micro- and macro-level. The article focuses on networks (thus communities) as a central research unit within studies of entrepreneurship and innovation. The second article contains a network analysis and depicts communities as central loci for cultural sources and knowledge. With data from the platform Meetup.com about events etc., the study explores which overarching communities and themes have been evolved in Berlin's start up and tech scene. While the latter study was about where to find new cultural sources, the last article addresses how to unlock such knowledge sources. It develops the concept of a cultural absorptive capacity, that is the capability of organizations to open up towards cultural sources. Furthermore, the article points to the role of knowledge intermediaries in the early phases of knowledge acquisition. Two case studies on companies working with artists illustrate the roles of such intermediaries and how they support firms to gain knowledge from cultural sources. Overall, this dissertation contributes to a better understanding of culture as a source for innovation from a theoretical, methodological, and practitioners' point of view. It provides basic research to unlock the potential of such new knowledge sources for companies - sources that so far have been neglected in innovation management.}, language = {en} }
