For technology addiction, researchers have developed a variety of self-reported scales in areas such as Internet, smartphones, videogames, social network sites (SNS) or television. However, no uniform criteria or definition exists for technology addiction. Utilized dimensions of technology addiction, to measure specific outcomes, lack a conceptual standard. Therefore, linkages between technology areas dimensions have not been examined in a broader way by the research community, in order to develop a uniform technology addiction scale. In this regard, firstly, a theoretical model was developed in order to extract common technology dimensions. Secondly, a systematic literature review in the areas of Internet, smartphone, video games and SNS was conducted in order to extract the dimensions used. To identify relevant studies, nine databases (GoogleScholar, ScienceDirect, PubMed, EmeraldInsight, Wiley, SpringerLink, ACM, iEEE and JSTOR) were searched, producing 4698 results, and 50 studies met the inclusion criteria. Thirdly, the developed theoretical model was utilized in order to determine the dimension in each of the identified scales. Based on analysis of the dimensional distributions, the findings suggest that there are common dimensions across areas of technology such as “compulsive use” and “negative outcomes” but also differences in dimensions across areas such as “social comfort” and “mood regulation”, which are more used in the area of SNS. Moreover, new dimensions such as “cognitive absorption” or “utility and function loss" for technology addiction were extracted, which should be considered as these have not yet been researched in a broader way. In addition, no gold standard for the conceptual criteria or definition for technology addiction has been developed yet. N2 - Digitale Medien durchdringen immer mehr das alltägliche Leben. Dadurch entsteht die Sorge, dass sich verschiedene Formen von Technologiesucht für Menschen herausbilden. Dabei haben Forscher eine Vielzahl von Messinstrumenten in den Bereichen Internet, Smartphones, Videospiele, Social Network Sites (SNS) oder Fernsehen entwickelt, um Süchte zu messen. Jedoch gibt es keine einheitlichen Kriterien oder eine standardisierte Definition der Technologiesucht, um diese für spezifische Dimensionen zu erfassen. Dies ist einer der Gründe warum die Forschungsgemeinschaft die Zusammenhänge zwischen den einzelnen Dimensionen nicht weiter untersucht hat, um einheitliche Messinstrumente zu entwickeln. Aus diesem Grund hat diese Studie zunächst ein theoretisches Modell entwickelt, um gemeinsame technologische Dimensionen zu extrahieren. Danach wurde eine systematische Literaturrecherche in den Bereichen Internet, Smartphone, Videospiele und SNS durchgeführt, um die verwendeten Dimensionen zu ermitteln. Um relevante Studien zu identifizieren, wurden neun Datenbanken (GoogleScholar, ScienceDirect, PubMed, EmeraldInsight, Wiley, SpringerLink, ACM, iEEE und JSTOR) durchsucht, die 4698 Ergebnisse lieferten. 50 dieser Messinstrumente haben die gesetzten Kriterien erfüllt. Darauffolgend ist das entwickelte theoretische Modell verwendet worden, um die Dimension in den 50 identifizierten Messinstrumenten zu bestimmen. Basierend auf der Analyse der dimensionalen Verteilung deuten die Ergebnisse darauf hin, dass es gemeinsame Dimensionen in Technologiebereichen wie z.B. "zwanghafte Nutzung" und "negative Ergebnisse” gibt. Aber es gibt auch Unterschiede in der Verteilung in den Dimensionen der Technologiebereiche. Zum Beispiel sind "sozialer Komfort" und "Stimmungsregulierung", im Bereich der SNS stärker vertreten. Zudem sind neue Dimensionen der Technologiesucht extrahiert worden. Zum Beispiel die "kognitive Absorption” oder der "Nutzen- und Funktionsverlust”, welche noch nicht breiter erforscht worden sind. Darüber hinaus ist noch kein Standard für die konzeptionellen Kriterien oder die Definition der Technologiesucht entwickelt worden.

To shed light on the consequences of videoconferencing at work, this study takes a granular look at the implications of the self-view feature for meeting outcomes. Building on self-awareness research and self-regulation theory, we argue that by heightening the state of self-awareness, self-view engagement depletes participants’ mental resources and thereby can undermine online meeting outcomes. Evaluation of our theoretical model on a sample of 179 employees reveals a nuanced picture. Self-view engagement while speaking and while listening is positively associated with self-awareness, which, in turn, is negatively associated with satisfaction with meeting process, perceived productivity, and meeting enjoyment. The criticality of the communication role is put forward: looking at self while listening to other attendees has a negative direct and indirect effect on meeting outcomes; however, looking at self while speaking produces equivocal effects.

Moving beyond the duality of personal benefits and privacy risks, we theorize that users hold social considerations (i.e., social benefits and risks) that underlie their acceptance decisions. To test our propositions, we chose the context of COVID-19 contact tracing apps and conducted a qualitative pre-study and longitudinal quantitative main study with 589 participants from Germany and Switzerland. Our findings confirm the prominence of individual privacy calculus in explaining intention to use and actual behavior. While privacy risks are a significant determinant of intention to use, social risks (operationalized as fear of mass surveillance) have a notably stronger impact. Our mediation analysis suggests that social risks represent the underlying mechanism behind the observed negative link between individual privacy risks and contact tracing apps' acceptance. Furthermore, we find a substantial intention–behavior gap.

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. The insights gathered in this thesis reveal theoretical implications and future opportunities for research in the field of information systems, practical implications for relevant stakeholders, and social implications related to the refugee crisis and the COVID-19 pandemic that must be addressed. N2 - Diese Dissertation beschäftigt sich mit zwei gesellschaftlichen Verwerfungen: den Flüchtlingswellen in Deutschland und der COVID-19-Pandemie. Dabei konzentrieren wir uns auf den Einsatz von Informations- und Kommunikationstechnologie (IKT) als eines der wichtigsten Mittel, um diese Verwerfungen zu mildern/abzufangen und soziale Eingliederung zu fördern. Soziale Verwerfungen führen in der Regel unter anderem zu Frustration und Fragmentierung. Daher ist es essenziell, die soziale Beteiligung von Einzelpersonen und Gesellschaften in solchen Phasen sicherzustellen. Im Kontext der Flüchtlingswellen konzentrieren wir uns auf die Gruppe der syrischen Geflüchteten, die ab 2015 in Deutschland angekommen sind, weil sie eine große kohärente Flüchtlingsgemeinschaft bilden. Insbesondere befassen wir uns mit der Rolle der IKT bei der sozialen Eingliederung von Geflüchteten in die Gesellschaft und der Frage, wie verschiedene IKT-Dienste (insbesondere Smartphones und soziale Netzwerke) eine bessere Integration und soziale Eingliederung von Geflüchteten fördern können. Im Zusammenhang mit der COVID-19-Pandemie konzentrieren wir uns auf das weit verbreitete unkonventionelle Arbeitsmodell „Work from Home“ (WFH). Unsere Forschung in diesem Zusammenhang fokussiert sich auf die Hauptkomponenten der Arbeit von zuhause und die Hauptunterschiede bei WFHErfahrungen, die auf persönlichen Merkmalen, z.B. Geschlecht und Familiensituation, beruhen. Wir konnten neue Erkenntnisse gewinnen, die sich auf folgenden vier etablierten Forschungsmethoden stützen: Literaturrecherche, Mixed-Methoden, qualitative Methoden und quantitative Methoden. Die Ergebnisse unserer Forschung wurden in acht Forschungsartikeln innerhalb von relevanten Tagungen und Fachzeitschriften für Informationssysteme veröffentlicht. Zu den wichtigsten Erkenntnissen der Forschung zur Rolle der IKTs bei der Integration Geflüchteter gehören: Smartphones sind ein zentrales Element der IKT-Nutzung von Geflüchteten. Sie betrachten IKT als Informations- und Machtquelle. Die soziale Verbundenheit von Geflüchteten hängt stark mit ihrer Internetnutzung zusammen. Sie verlassen sich nicht nur auf traditionelle Methoden, um die deutsche Sprache zu lernen und sich weiterzubilden. Die Möglichkeit, das Smartphone jederzeit und überall zu nutzen, gibt Geflüchteten ein Gefühl der globalen Vernetzung und IKT tragen dazu bei, Geflüchtete in folgenden drei Punkten zu stärken: Beteiligung an der Gemeinschaft, Gefühl der Kontrolle und Selbstwirksamkeit. Zu den wichtigsten Erkenntnissen aus dem COVID-19-WFM-Stream gehören: Das Geschlecht und die Anwesenheit von Kindern unter 18 Jahren beeinflussen die Kontrolle der Arbeitnehmer über ihre Zeit, den technologischen Nutzen und den WFH-Konflikt, ohne jedoch ihre Einstellung zu WFH zu beeinträchtigen. Sowohl persönliche als auch technologische Faktoren beeinflussen die Einstellung eines Einzelnen zur Arbeit von zuhause und seine Produktivität. Zum Zeitpunkt der Einreichung dieser Dissertation werden in fortlaufenden Forschungsprojekte weitere Erkenntnisse zu diesem Themenbereich gesammelt. Diese Dissertation trägt einerseits zur Diskussion innerhalb der Gesellschaft für Informationssysteme bei, indem sie aufzeigt wie verschiedene IKT-Lösungen eingesetzt werden können, um die soziale Eingliederung von Geflüchteten in ihren neuen Gemeinschaften zu fördern und so zu einer integrativen Gesellschaft beizutragen. Andererseits steuert die Dissertation neues Wissen zu der Forschung über COVID-19 bei, insbesondere zur Umstellung des Arbeitsumfelds im Kontext von Heimarbeit (WFH). Die im Rahmen dieser Arbeit gesammelten Erkenntnisse tragen maßgeblich dazu bei, theoretische Implikationen und zukünftige Forschungsmöglichkeiten auf dem Gebiet der Informationssysteme aufzudecken. Ferner werden praktische Implikationen für relevante Stakeholder und soziale Auswirkungen im Zusammenhang mit der Flüchtlingskrise und der COVID-19-Pandemie adressiert, die in Zukunft entscheidend und wichtig sein werden.

The information systems (IS) community has begun to research how information and communications technologies can assist immigrants and refugees, such as by examining how countries can facilitate social-inclusion processes. Migrants face the challenge of joining closed communities that cannot integrate or fear doing so. We conducted a panel discussion at the 2019 Americas Conference on Information Systems (AMCIS) in Cancun, Mexico, to introduce multiple viewpoints on immigration. In particular, the panel discussed how technology can both support and prevent immigrants from succeeding in their quest. We conducted the panel to stimulate a thoughtful and dynamic discussion on best practices and recommendations to enhance the discipline's impact on alleviating the challenges that occur for immigrants in their host countries. In this panel report, we introduce the topic of using ICT to help immigrants integrate and identify differences between North/Central America and Europe. We also discuss how immigrants (particularly refugees) use ICT to connect with others, feel that they belong, and maintain their identity. We also uncover the dark and bright sides of how governments use ICT to deter illegal immigration. Finally, we present recommendations for researchers and practitioners on how to best use ICT to assist with immigration.

This sudden venue change can affect academics' productivity and exacerbate the challenges that confront universities as they face an uncertain future. In this paper, we identify factors that influence academics' productivity while working from home during the mandate to self-isolate. From analyzing results from a global survey we conducted, we found that both personal and technology-related factors affect an individual's attitude toward working from home and productivity. Our results should prove valuable to university administrators to better address the work-life challenges that academics face.

This study proposes a new approach to understanding extreme events and boom-bust processes in agricultural markets. Using weekly futures data for twelve indexed agricultural commodities during 2006 to 2016, we find that extreme price changes, located in the 10% tails of the distribution, cluster across agricultural markets. We then implement a multinomial logit model to investigate which factors are associated with the propagation of extreme events. Specifically, we disentangle three transmission conduits. (1) The macroeconomic conduit captures the possibility that the synchronized extreme price events are generated by business-cycle driven demand shifts mainly in emerging economies. (2) The financial conduit refers to potential links between extreme returns and the increasing flow of money from financial participants into agricultural futures markets. (3) Finally, the energy conduit accounts for possible spillover effects due to oil price shocks. Our results indicate an important role of managed money positions and oil prices while the real demand channel remains mostly insignificant. (C) 2017 Elsevier Ltd. All rights reserved.

We extend their analysis by analyzing the case of competition in prices. Further we compare the incentives to merge with Bertrand and Cournot competition.

Gross and Holahan (2003) use a similar model with price setting firms, we compare their results with ours to analyze the impact of the mode of competition on sustainability of collusion. Further we analyze the impact of collusion on social welfare and find that collusion may be welfare enhancing.

This finding is contrary to the results of Shachmurove and Spiegel (1995) as well as Tharakan and Thisse (2002), who use related models to analyze size effects in international trade, where the small country usually gains from trade and the large country may lose.

We find that the stability of the cartel depends on the relative market size of each firm. Collusion is not attractive for firms with a small home market, but the incentive for collusion increases when the firm’s home market is getting larger relative to the home market of the competitor. The highest stability of a cartel and additionally the highest social welfare is found when regions are symmetric. Further we can show that a monetary transfer can stabilize the market sharing agreement.

Needs and emotions during classes BT - the Felix-App: new ways of feedback and evaluating classes in real time T2 - 9th International Conference on Society and Information Technologies (ICSIT 2018) N2 - The “output-orientation” is omnipresent in teacher education. In order to evaluate teachers' and students' performances, a wide range of different quantitative questionnaires exist worldwide. One important goal of teaching evaluation is to increase the quality of teaching and learning. The author argues, that standard evaluations which are typically made at the end of the semester are problematic due to two reasons. The first one is that some of the questions are too general and don`t offer concrete ideas as to what kind of actions can be taken to make the courses better. The second problem is that the evaluation is mostly made when the course is already over. Because of this criticism, Apelojg invented the Felix-App which offers the possibility to give feedback in real-time by asking for the emotions and needs that occur during different learning situations. The idea is very simple: positive emotions and satisfied needs are helpful for the learning process. Negative emotions and unsatisfied needs have negative effects on the learning process. First descriptive results show, that “managing emotions” during classes can have positive effects on both motivation and emotions.

This paper analyzes whether the three aspects involving innovative activity - R&D; innovative output; and productivity - hold for knowledge intensive services. Combining the models of Crepon et al. (1998) and of Ackerberg et al. (2015), allows for causal interpretation of the relationship between innovation output and labor productivity. We find that knowledge intensive services benefit from innovation activities in the sense that these activities causally increase their labor productivity. Moreover, the firm size advantage found for manufacturing in previous studies nearly disappears for knowledge intensive services.

In this paper we offer a theoretical model to analyze relationship banking and the pricing behavior of banks in a Bertrand competition framework with monitoring costs. We show that the lack of reliable information leads to comparable high interest rates even if a long-term relationship between borrower and bank exists. The paper offers a theoretical explanation why SMEs often are faced with borrowing constraints.

Chapter 2 deals with two studies on effective income taxation, based on representative micro data sets from tax statistics. The first study analyses the effective income taxation at the individual level, in particular with respect to the top incomes. It is based on an integrated micro data file of household survey data and income tax statistics, which captures the entire income distribution up to the very top. Despite substantial tax base erosion and reductions of top tax rates, the German personal income tax has remained effectively progressive. The distribution of the tax burden is highly concentrated and the German economic elite is still taxed relatively heavily, even though the effective tax rate for this group has significantly declined. The second study of Chapter 2 highlights the effective income taxation of functional income sources, such as labor income, business and capital income, etc. Using income tax micro data and microsimulation models, we allocate the individual income tax liability to the respective income sources, according to different apportionment schemes accounting for losses. We find that the choice of the apportionment scheme markedly affects the tax shares of income sources and implicit tax rates, in particular those of capital income. Income types without significant losses such as labor income or transfer incomes show higher tax shares and implicit tax rates if we account for losses. The opposite is true for capital income, in particular for income from renting and leasing. Chapter 3 presents two studies on business taxation, based on representative micro data sets from tax statistics and the microsimulation model BizTax. The first part provides a study on fundamental reform options for the German local business tax. We find that today’s high concentration of local business tax revenues on corporations with high profits decreases if the tax base is broadened by integrating more taxpayers and by including more elements of business value added. The reform scenarios with a broader tax base distribute the local business tax revenue per capita more equally across regional categories. The second study of Chapter 3 discusses the macroeconomic performance of business taxation against the background of corporate income. A comparison of the tax base reported in tax statistics with the macroeconomic corporate income from national accounts gives hints to considerable tax base erosion. The average implicit tax rate on corporate income was around 20 percent since 2001, and thus falling considerably short of statutory tax rates and effective tax rates discussed in the literature. For lack of detailed accounting data it is hard to give precise reasons for the presumptive tax base erosion. Chapter 4 deals with several assessment studies on the ecological tax reform implemented in Germany as of 1999. First, we describe the scientific, ideological, and political background of the ecological tax reform. Further, we present the main findings of a first systematic impact analysis. We employ two macroeconomic models, an econometric input-output model and a recursive-dynamic computable general equilibrium (CGE) model. Both models show that Germany’s ecological tax reform helps to reduce energy consumption and CO2 emissions without having a substantial adverse effect on overall economic growth. It could have a slightly positive effect on employment. The reform’s impact on the business sector and the effects of special provisions granted to agriculture and the goods and materials sectors are outlined in a further study. The special provisions avoid higher tax burdens on the energy-intensive production. However, they widely reduce the marginal tax rates and thus the incentives to energy saving. Though the reform of special provisions 2003 increased the overall tax burden of the energy-intensive industry, the enlarged eligibility for tax rebates neutralizes the ecologic incentives. Based on the Income and Consumption Survey of 2003, we have analyzed the distributional impact of the ecological tax reform. The increased energy taxes show a clear regressive impact relative to disposable income. Families with children face a higher tax burden relative to household income. The reduction of pension contributions and the automatic adjustment of social security transfers widely mitigate this regressive impact. Households with low income or with many children nevertheless bear a slight increase in tax burden. Refunding the eco tax revenue by an eco bonus would make the reform clearly progressive. N2 - Diese Habilitationsschrift fasst verschiedene empirische Studien zu Steuerlastverteilung und Steuerreformen in Deutschland zusammen. In Kapitel 2 werden zwei Studien zur effektiven Einkommensteuerbelastung dargestellt. Die erste Studie analysiert die effektive Einkommensteuerbelastung auf der persönlichen Ebene, insbesondere bei Personen mit hohen Einkommen. Grundlage der Analyse ist ein integrierter Mikrodatensatz aus Haushaltserhebungen und Steuerstatistik, der die vollständige Einkommensverteilung zuverlässig abbildet. Trotz erheblicher Steuerbegünstigungen und Senkungen der Spitzensteuersätze wirkt die deutsche Einkommensteuer klar progressiv, auch wenn die Belastung der Top-Verdiener in den letzten Jahren deutlich gesunken ist. Die zweite Studie in Kapitel 2 analysiert die effektive Einkommensteuerbelastung von verschiedenen funktionalen Einkommensquellen. Auf Grundlage von steuerstatistischen Mikrodaten und Mikrosimulationsmodellen analysieren wir die Anteile der Einkunftsarten an der Steuerbelastung für verschiedene Aufteilungsregeln unter Berücksichtigung von Verlusten. Die Wahl der Aufteilungsregel wirkt sich spürbar auf den Steueranteil und die impliziten Steuersätze von Einkommensarten aus, wenn Verluste berücksichtigt werden, vor allem bei den Vermögenseinkommen. Kapitel 3 enthält zwei Studien zur Unternehmensbesteuerung, die auf repräsentativen Einzeldatensätzen der Steuerstatistik und dem Mikrosimulationsmodell BizTax basieren. Zunächst wird eine Mikrosimulationsanalyse zu grundlegenden Reformmodellen für die Gewerbesteuer vorgestellt. Die Ergebnisse zeigen, dass die starke Konzentration des Gewerbesteueraufkommens auf die Unternehmen mit höheren Gewinnen deutlich vermindert werden kann, wenn die Bemessungsgrundlagen verbreitert werden, durch Einbeziehung aller Unternehmen und eine Ausweitung auf weitere Komponenten der betrieblichen Wertschöpfung. Diese Reformszenarien verteilen das Steueraufkommen je Einwohner deutlich gleichmäßiger über die Regionen. In der zweiten Studie des Kapitels 3 analysieren wir das Unternehmensteueraufkommen vor dem Hintergrund der gesamtwirtschaftlichen Unternehmensgewinne. Ein Vergleich der steuerlichen Bemessungsgrundlagen mit den entsprechenden Unternehmensgewinnen der Volkswirtschaftlichen Gesamtrechnungen ergibt eine beträchtliche Besteuerungslücke. Die durchschnittliche effektive Unternehmensteuerbelastung dürfte sich seit 2001 um 20 Prozent bewegt haben. Dies ist deutlich niedriger als die nominalen tariflichen Steuersätze und die effektiven Steuersätze, die in der Literatur ermittelt werden. Mangels detaillierter statistischer Erfassung der steuerlichen Gewinnermittlung ist es derzeit nicht möglich, diese Besteuerungslücke genauer aufzuklären. In Kapitel 4 werden verschiedene Studien zur ökologischen Steuerreform dargestellt. Zunächst werden die wissenschaftlichen, ideologischen und politischen Hintergründe dieser Reform erläutert. Danach wird eine erste systematische Wirkungsanalyse dargestellt. Dabei werden zwei makroökonomische Modelle eingesetzt, ein ökonometrisches Input-Output-Modell und ein empirisches rekursiv-dynamisches allgemeines Gleichgewichtsmodell. Die Ergebnisse zeigen, dass die ökologische Steuerreform den Energieverbrauch und die CO2-Emissionen spürbar senken kann, ohne dass dies nennenswerte Wachstumseinbußen nach sich ziehen würde. Ferner löst die Reform leicht positive Beschäftigungseffekte aus. Die Wirkungen der ökologischen Steuerreform nach Wirtschaftsbereichen und die Wirkungen der Steuervergünstigungen für Landwirtschaft und Produzierendes Gewerbe werden in einer weiteren Studie analysiert. Die Steuervergünstigungen vermeiden höhere Belastungen in den energieintensiven Produktionsbereichen. Zugleich reduzieren sie die Grenzbelastungen und somit die Anreize zum Energiesparen in diesen Branchen weitgehend. Die Reform der Steuervergünstigungen hat zwar die Belastungen für die energieintensive Wirtschaft seit 2003 erhöht. Die zusätzlichen Anreizwirkungen wurden aber durch die Ausweitung des „Spitzenausgleichs“ konterkariert. Die Effekte der ökologischen Steuerreform auf die Einkommensverteilung wurden auf Grundlage der Einkommens- und Verbrauchsstichprobe 2003 untersucht. Die erhöhten Energiesteuern wirken klar regressiv bezogen auf das verfügbare Einkommen. Familien mit Kindern werden relativ stärker belastet. Die Senkung der Rentenbeiträge und die automatische Anpassung von Sozialleistungen mildern die regressive Belastungswirkung. Bei Haushalten mit niedrigen Einkommen oder bei Familien mit vielen Kindern bleiben jedoch Nettobelastungen bestehen. Eine Rückerstattung des Ökosteueraufkommens durch einen „Ökobonus“ würde die gesamten Verteilungswirkungen der Reform deutlich progressiv machen.

Since top wealth is likely to be under-represented in household surveys, we integrate big fortunes from rich lists, estimate a Pareto distribution, and impute the missing rich. In addition to the Forbes list, we rely on national rich lists since they represent a broader base of the big fortunes in those countries. As a result, the top 1% wealth share increases notably for the three selected countries after imputing the top wealth. We find that national rich lists can improve the estimation of the Pareto coefficient in particular when the list of national USD billionaires is short.

Over time, the federal administration has developed into a highly differentiated 'administrative zoo' with a large number of species, questioning the image of a well-ordered German bureaucracy. The article addresses organizational changes among non-ministerial agencies during the past 20 years and ministry-agency relations, drawing on data from a comprehensive survey of the federal administration. The structural changes we observe are neither comprehensive nor planned; they are much more evolutionary than revolutionary, driven by sectoral policies and not by any overall agency policy, supported more by regulatory than by managerial reforms, and most of the changes are horizontal mergers or successions of existing organizations, while we find almost no evidence for hiving-off from ministries to agencies. At the same time, federal agencies report a lot of bureaucratic discretion, whereas they perceive substantial levels of 'red tape' due to administrative regulations. We also find that traditional, hierarchical modes of ministerial oversight are still dominating; only few agencies have performance agreements with measurable goals.

This study examines the impact of a voluntary intra-curricular internship experience during university studies on the probability of being invited to a job interview. To estimate a causal relationship, we conducted a randomised field experiment in which we sent 1248 fictitious, but realistic, resumes to real job openings. We find that applicants with internship experience have, on average, a 12.6% higher probability of being invited to a job interview.

Social policy, already overstrained due to the demands of transition, was unable to cope effectively with the rapidly spreading state of emergency. The following essay analyses the development of the social indicators and instruments of social security in the years 1990 to 1998. In addition to unemployment and unemployment insurance, the issue of pensions and poverty will also be examined.

The transfers are carried out so as to vest the new private owners with the full property rights of use and disposal over their property, these rights being guaranteed by the legal framework established by the rule of law. In Bulgaria, one can distinguish between three main stages in the process of privatisation. Each was shaped by the conflicting resolutions of frequently changing governments and meant to serve different political goals. The first stage (1990-1993) is characterised by the blockade of legal privatisation, as ‘spontaneous privatisation’ was accorded high priority. As in other former socialist countries, great emphasis was placed on the so-called commercialisation of state-owned enterprises. This did not involve the actual transfer of State property into private hands, but rather the independent transformation of state-owned enterprises into joint-stock companies, as well as the establishment of subsidiary companies.1 The goals of introducing more efficient structures and applying modern methods of production by transferring property to a more suitable management were not achieved. The second stage (1993-1995) is a cash privatisation, which laid the foundation for an employee/management buy-out, aided by the legal provisions granting concessions in the payment of instalments. The most important factor in the third stage of the process of privatisation in Bulgaria was the adoption of the mass privatisation model as an alternative method of procedure. In 1996, legal regulations for mass privatisation were introduced and a privatisation fund was established. In the meantime, the process has evolved into its fourth stage, during which a strategy of privatisation has been formulated under the supervision of a monetary council, and various agreements with the IMF and the World Bank are being adhered to. Privatisation is the decisive factor in the structural reforms of East European countries. The problem of converting State property into more effective forms of property management has been exacerbated by the additional demand of carrying out the far-reaching structural changes as swiftly as possible. The expectation that a large part of State property would be privatised within a short time in Bulgaria, has not been met for a number of reasons. When the reforms began, the private sector was too weakly developed to become a catalyst for structural changes. Until 1995 there were no laws regulating the stock exchange or securities and bonds - the capital market was practically non-existent. Moreover, the various political parties could not agree upon the various models and objectives of privatisation. The population itself had no capital. The restitution of private ownership which will not be discussed in further detail was limited to the smallest businesses, traders and workshops. Furthermore, the Privatisation Agency and State authorities employed to initiate the privatisation process lacked experience. Another problem hindering privatisation was that the laws passed lacked precision and were constantly subject to change.

A1 - Seegebarth, Barbara A1 - Peyer, Mathias T1 - A sustainable pathway to consumer wellbeing BT - the role of anticonsumption and consumer empowerment JF - The Journal of consumer affairs N2 - This study investigates the effect of different anticonsumption constructs on consumer wellbeing. The study assumes that people will only lower their level of consumption if doing so does not also lower personal wellbeing. More precisely, this research investigates how specific subtypes of sustainable anticonsumption (e.g., voluntary simplicity, collaborative consumption, and debt-free living) relate to different states of consumer's wellbeing (e.g., financial, psychosocial, and subjective wellbeing). This work also examines whether consumer empowerment can improve personal wellbeing and strengthen the anticonsumption wellbeing relationship. The results show that voluntarily foregoing consumption does not reduce wellbeing and consumer empowerment plays a significant role in supporting sustainable pathways to consumer wellbeing. This study reasons that empowerment improves consumer sovereignty, but may be detrimental for consumers heavily concerned about debt-free living. The present investigation concludes by proposing implications for public and consumer policymakers wishing to promote appropriate sustainable (anticonsumption) pathways to consumer wellbeing.

Compared with the vast amount of studies concerning environmentally conscious consumer behaviour, relatively little is known about socially conscious consumption. The present paper focuses on fair consumption as an important aspect of social consumption. In our study, consciousness for fair consumption (CFC) is defined as a latent disposition of consumers to prefer products that are produced and traded in compliance with fair labour and business practices. A scale to measure CFC was conceptualized and tested in three independent empirical studies. Two studies were conducted at European universities (2010 and 2012) and used 352 and 362 undergraduate business students respectively. The third study, conducted in 2011, used 141 employees at a European university. The results confirmed the reliability and validity of the new CFC scale across samples. While being moderately related to other aspects of sustainable consumption such as ecological concern and moral reasoning, CFC was significantly distinct from those concepts. Most importantly, it was established that the CFC, as measured by the new CFC scale, is a strong determinant of consumption of fair trade products that has been neglected in existing research.

N2 - The thesis assesses the contribution of technology option of Carbon Capture and Sequestration (CCS) to climate change mitigation. CCS means that CO2 is captured at large industrial facilities and sequestered in goelogical structures. The technology uses the endogenous growth model MIND. Herein the various climate change mitigation options of reducing economic growth, increasing energy efficiency, changing the energy mix and CCS are assessed simultaneously. An important question is whether CCS is a temporary or long-term solution. The results show that in the middle of the 21st century CCS has its peak contribution, which allows prolonged use of relatively cheap fossil energy carriers. However, this leads to delayed introduction of renewable energy carriers. The technology path ways are accombined with different costs of climate change mitigation. The use of CCS delays and reduces the costs of climate change mitigation. However, the delayed introduction of renewable energy carriers leads to reduced technological learning, which induces higher costs in the longer term. All in all the temporary use of CCS reduces the costs of climate change mitigation costs. The result is robust, which is tested with various uncertainty analysis. N2 - Die Arbeit befasst sich mit der Bewertung der technischen Option zum Klimaschutz CO2 an grossen industriellen Anlagen abzufangen und in geologischen Lagerstätten zu speichern. Die Technologiebewertung wird mit Hilfe des endogenen Wachstummodells MIND untersucht. Darin werden die Klimaschutzoptionen geringere wirtschaftliche Entwicklung, Steigerung der Energieeffizienz, Veränderung des Energiemixes und eben CO2 Abscheidung simultan bewertet. Eine wichtige Frage ist ob die Abscheidung von CO2 eine langfristige oder eine Zwischenlösung ist. Es zeigt sich, dass sie um die Mitte des 21ten Jahrhunderts ihren grössten Beitrag zum Klimaschutz leistet und die Nutzung der relativ kostengünstigen fossilen Energieträger verlängert. Das führt zu einer späteren Einführung erneuerbarer Energietechnologieen. Mit diesen unterschiedlichen Technologiepfaden gehen auch verschiedene ökonomische Kostenverläufe des Klimaschutzes einher. Die Verwendung von CO2 Abscheidung verschiebt die Kosten in die Zukunft und drückt ihre Spitze. Da es aber gleichzeitig zu geringerer Technologieentwicklung bei erneuerbaren Energieen führt entstehen wiederum Kosten. Unterm Strich lohnt sich die Einführung der CO2 Abscheidung als temporärer Beitrag zum Klimaschutz. Dieses Ergebnis konnte mit einer Reihe von Unsicherheitsanalysen erhärtet werden.

We present a model of a marriage market with positive assortative matching, where in equilibrium, the poorest women stay single. Couples have to decide on the number of children and spousal specialization in home production of public goods and child care. We then study how child care provision affects the equilibrium. Due to specialization in home production, the incentive to use child care is smaller for married mothers than for single mothers. We show that this increases the number of single mothers and the divorce rate. Using survey data from Germany, we present suggestive empirical evidence consistent with this finding.

JF - Research Policy N2 - We analyze the link between R&D, innovation, and productivity in MSMEs with a special focus on micro firms with fewer than 10 employees; usually constituting the majority of firms in industrialized economies. Using the German KfW SME-panel, we examine to what extent micro firms are different from other firms in terms of innovativeness. We find that while firms engage in innovative activities with smaller probability, the smaller they are, for those firms that do make such investment, R&D intensity is larger the smaller firms are. For all MSMEs, the predicted R&D intensity is positively correlated with the probability of reporting innovation, with a larger effect size for product than for process innovations. Moreover, micro firms benefit in a comparable way from innovation processes as larger firms, as they are similarly able to increase their labor productivity. Overall, the link between R&D, innovation, and productivity in micro firms does not largely differ from their larger counterparts. (C) 2016 Elsevier B.V. All rights reserved.

T1 - Revisiting public investment BT - consumption equivalent public capital and the social discount rate N2 - The consumption equivalence method is the theoretical basis of public cost-benefit analysis. Consumption equivalence public capital prices are explicitly introduces in order to sufficiently care for the opportunity cost of public expenditure. This can solve the dispute about the social rate of discount within public cost-benefit analysis witch was generated on a criterion looking similar to the capital value formula, known as Lind’s approach. The social rate of discount is liberated from opportunity costs considerations and the discounting away of the effects for future welfare vanishes. The corresponding question whether one should accept a positive value of the pure rate of social time preference is an old issue. Its current state between the prescriptive and descriptive view can also be interpreted as a consequence of the oversimplification of standard cost– benefit analysis. But apart from an economic self-process the pure rate of social time preference is also defined as a business-as-usual value of social distance discounting. Hence, a political choice has to be made about this rate which is free in principal.

T1 - General classification of social choice situations T2 - Finanzwissenschaftliche Diskussionsbeiträge N2 - An exhaustive and disjoint decomposition of social choice situations is derived in a general set theoretical framework using the new tools of the Lifted Pareto relation on the power set of social states representing a pre-choice comparison of choice option sets. The main result is the classification of social choice situations which include three types of social choice problems. First, we usually observe the common incompleteness of the Pareto relation. Second, a kind of non-compactness problem of a choice set of social states can be generated. Finally, both can be combined. The first problem root can be regarded as natural everyday dilemma of social choice theory whereas the second may probably be much more due to modeling technique implications. The distinction is enabled at a very general set theoretical level. Hence, the derived classification of social choice situations is applicable on almost every relevant economic model.

Previous reports in this area indicated preferable directions of research to be taken in order to prove various hypotheses of the purposefulness of an integral approach to industrial policy and social security in the analysis of economic processes in transition (see Weikard 1997). This paper summarises the results and draws conclusions from a questionnaire study on subsidies, social benefits and economic policy in Polish firms during the process of transformation. Our results and conclusions show the scope and character of the processes in the area of industrial and social policy in the period 1994 to 1997. The paper is divided into five parts. The first part concerns the aims and methodology of the questionnaire; it also gives a brief description of the sample. The second part shows how enterprises dealt with the issues of employment and wages in this period. The third part characterises industrial policy at the corporate level, while the next presents results from the survey of various social schemes pursued. The final part aims at an integral approach in the analysis of various processes taking place in Polish enterprises. The survey was conducted in the period April to June 1998. Its aim was to observe certain phenomena occurring at the corporate level. The questionnaire was distributed among the managers, directors and presidents of large-size enterprises, which had been selected to satisfy the following three criteria. Firstly, the number of employees had to be considerable (over 300 workers). This criterion was applied following the consideration that certain social phenomena are more conspicuous in enterprises with large manpower. Secondly, only operating enterprises were selected, the enterprises which closed down were disregarded. Finally, for the purposes of the survey the units differed as regards their legal situation and form of ownership. Out of over 1800 enterprises 370 units were drawn where we sent the questionnaire. Unfortunately, as many as 51.9% of the respondents refused co-operation, questions to a certain extent puts the representativeness of the sample in question. Finally, 178 questionnaires were subsequently completed and returned for analysis. However, not all of these questionnaires included full answers to all of the 75 questions; therefore, while discussing the results of the survey we have indicated the number of relevant answers we have received.

Platform owners provide platform boundary resources that allow for application development. For developers, platform integration, understood as the employment of platform resources, helps to realize application functionality effectively. Simultaneously, it requires integration effort and increases dependencies. Developers are interested to know whether integration contributes to success in hypercompetitive platform settings. While aspects of platform participation have been studied, research on a comprehensive notion of integration and related implications are missing. By proposing a platform integration model, this study supports a better understanding of integration. Concerning dynamics related to integration, effects were tested using information from over 82,000 Apple AppStore applications. Regression model analysis reveals that application success and customer satisfaction is positively influenced by platform integration. To achieve superior results, developers should address multiple aspects of integration, such as devices, data, the operating system, the marketplace as well as other applications, and provide updates. Finally, the study highlights the importance for all platform participants and their possibilities to employ integration as a strategic instrument.

The impetus for proposing this specific PSG was the growing importance of the local level within the multi-level governance system in the European Union and most of its member states. The PSG 4 acts as a European network of research activities inside and outside EGPA, producing joint publications and organising scientific debates on many problems of the development of municipalities and local authorities. Our focus was on discussing both how to improve democracy by increased participation and deliberation, and how to secure provision of services in an efficient way in developed welfare societies. This includes analysing several forms of administrative changes and reforms at the local level and research of representative, direct and cooperative democracy at local level in a cross-European comparison.

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.

We developed a conceptual model that links empowering leadership at the individual level and at the group level (mean as well as dispersion) to individuals' career self-efficacy and career satisfaction. To test our model, we used questionnaire data from a multilevel data set of 2493 employees in leadership positions nested in 704 teams from a large German corporation. Hierarchical linear regression analyses showed that empowering leadership at the individual level was positively related to career self-efficacy, which in turn mediated the relationship between empowering leadership and career satisfaction. Empowering leadership at the group level was positively related to career self-efficacy when it was conceptualized as leadership differentiation (i.e., the standard deviation of empowering leadership ratings), but not when it was conceptualized as leadership climate (i.e., mean empowering leadership ratings). Career self-efficacy in turn mediated the relationship between empowering leadership differentiation and career satisfaction. Finally, we found a negative relationship between empowering leadership. differentiation and career satisfaction. (C) 2015 Elsevier Inc. All rights reserved.

At the core is the development of an analytical model for comparing efforts of performance budgeting (PB). Evidence in ten cases indicates that performance structures and the span of performance differ, that performance indicators are far from always measuring outcomes or outputs, and that future and past performance figures are often absent. Nevertheless similar learning trajectories do exist. Possible explanations for the variation involve the varying degrees of reform implementation, experience with PB and prevailing institutional arrangements.

Our paper attempts to trace these differences in the labor market performance back to the regions' specialization in products that are more or less advanced in their product cycle. The model we develop shows how individual profit and utility maximization endogenously yields higher employment levels in the beginning. In later phases, however, employment decreases in the presence of process innovation. Our model suggests that the only way to escape from this vicious circle is to specialize in products that are at the beginning of their "economic life". The model is based on an interaction of demand and supply side forces.

The paper presents a model with endogenous fertility, female labour supply and childcare choices driven by cultural attitudes which fits these facts.

Building height limits and urban greenhouse gas emissions JF - Regional science and urban economics N2 - This paper studies the effectiveness of building height limits as a policy to limit greenhouse gas (GHG) emissions. It shows that building height limits lead to urban sprawl and higher emissions from commuting. On the other hand, aggregate housing consumption may decrease, which reduces emissions from residential energy use. A numerical model is used to evaluate whether total GHG emissions may be lower under building height restrictions. Welfare is not concave in the strictness of building height limits, so either no limit or a very strict one (depending on the strength of the externality) might maximize welfare. The paper discusses several extensions, such as congestion, endogenous transport mode choice, migration, and urban heat island effect. (C) 2016 Elsevier B.V.

T1 - Optimal energy taxation in cities JF - Journal of the Association of Environmental and Resource Economists : JAERE N2 - This paper presents the first investigation of the effects of optimal energy taxation in an urban spatial setting, where emissions are produced both by residences and commuting. When levying an optimal direct tax on energy or carbon use is not feasible, the analysis shows that exactly the same adjustments in resource allocation can be generated by the combination of a land tax, a housing tax, and a commuting tax. We then analyze the effects of these taxes on urban spatial structure, showing that they reduce the extent of commuting and the level of housing consumption while increasing building heights, generating a more-compact city with a lower level of emissions per capita.

While the existing spatial econometric literature focuses on tax and spending competition, very little is known about spatial interaction via public debt. If jurisdictions compete for mobile capital to finance public spending, they may compete in debt levels as well as taxes. We use a theoretical model to derive the reaction of jurisdictions' debt levels to their neighbors' debts. We then estimate the spatial interdependence of public debt among German municipalities using a panel on municipalities in the two largest German states from 1999 to 2006. We find significant and robust interaction effects between debt levels of neighboring municipalities, which we compare to spatial tax and spending interactions. The results indicate that a municipality increases its per capita debt by 16-33 Euro as a reaction to an increase of 100 Euro in neighboring municipalities. (C) 2015 Elsevier B.V.

This paper establishes a simple core-periphery model with monocentric cities, which comprises key forces that shape the structure and interrelation of cities to study the impact of the urban evolution on the environment. We focus on global warming and the potential of unfettered market forces to economize on emissions. The model parameters are chosen to match the dichotomy between average "large" and "small" cities in the urban geography of the United States, and the sectoral greenhouse gas emissions recorded for the United States. Based on numerical analyzes we find that a forced switch to a system with equally sized cities reduces total emissions. Second, any city driver which pronounces the asymmetry between the core and the periphery drives up emissions in the total city system, too, and the endogenous adjustment of the urban system accounts for the bulk of the change in emissions. Third, none of the city drivers gives rise to an urban environmental Kuznets curve according to our numerical simulations. Finally, the welfare-maximizing allocation tends to involve dispersion of cities and the more so the higher is the marginal damage from pollution.

Rather than concentrating on a specific commodity subgroup or a particular type of commodity traders, we provide an extensive overview of the behavior across all market participants and their influence on commodity prices by using a broad set of commodity futures contracts. Although commodity futures returns show co-movement with financial fundamentals (U.S. dollar index, equity, and bond markets), based on the Disaggregated Commitment of Traders Report (DCOT), this relationship cannot be attributed to trading activity. Pricing in commodity markets can be predominantly attributed to hedgers and influential speculators (money managers), whereas small speculators (nonreportable traders) are crucial to some soft commodity futures similar to dealers in metals commodity futures. Furthermore, we find limited cases where inventory changes exert a sizable influence on position changes of DCOT traders.

Building on the OI capability concept, our results demonstrate that chefs use absorptive and desorptive capacity (AC, DC) as means to generate and market culinary innovations, respectively. Moreover, we found that chefs almost exclusively rely on their own inventive and innovative capabilities in the early stages of the culinary innovation process. In subsequent phases, however, chefs increasingly integrate other sources such as employees, suppliers, and guests. Our study contributes to the literature in two ways. First, we research the individual level within the OI process, and second, we provide insight into OI practices in the creative industries.

Two general equilibrium models establish the base for this evaluation, each adding its puzzle piece to the urban sustainability discourse and examining the role of non-market-based and market-based policies for balanced growth and welfare improvements in different theory settings. Sustainable urban growth either calls for policy actions or a green energy transition. Further, R&D market failures can pose severe challenges to the sustainability of urban growth and the social optimality of decentralized allocation decisions. Still, a careful (holistic) combination of policy instruments can achieve sustainable growth and even be first best. N2 - Diese Dissertation untersucht die Determinanten für ein nachhaltiges und sozial optimales Wachstum in den Städten. Zwei endogene Wachstumsmodelle untersuchen hierzu die Rolle von nichtmarktbasierten und marktbasierten Politikeingriffen. Jedes Modell fügt dabei dem städtischen Nachhaltigkeitsdiskurs sein eigenes Puzzleteil hinzu. Nachhaltiges städtisches Wachstum erfordert entweder politische Maßnahmen oder eine grüne Energiewende. Darüber hinaus können Verzerrungen im Forschungsmarkt ernsthafte Herausforderungen für die Nachhaltigkeit des städtischen Wachstums und für die soziale Optimalität dezentralisierter Allokationsentscheidungen darstellen. Dennoch kann eine sorgfältige (ganzheitliche) Kombination von Politikinstrumenten Erfolg haben und zu einem sozial optimalen Resultat führen.

The effects of blockchain on the relationship of public administrations with external stakeholders T1 - Auf dem Weg zu gemeinsam erbrachten Verwaltungsleistungen? Die Auswirkungen von Blockchain auf die Beziehungen zwischen öffentlichen Verwaltungen und externen Akteuren N2 - Public administrations confront fundamental challenges, including globalization, digitalization, and an eroding level of trust from society. 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. N2 - Öffentliche Verwaltungen stehen vor grundlegenden Herausforderungen, darunter Globalisierung, Digitalisierung und ein schwindendes Vertrauen der Gesellschaft. Durch die gemeinsame Erbringung von Verwaltungsleistungen mit anderen Akteuren können öffentliche Verwaltungen auf diese Herausforderungen reagieren. Dies erhöht die Bedeutung der interorganisatorischen Governance – eine Entwicklung, die oft als New Public Governance bezeichnet wird und die bisher nicht realisiert wurde, weil sich die öffentlichen Verwaltungen auf organisationsinterne Praktiken konzentrieren und der traditionellen "Governmental chain" folgen. E-Government-Initiativen, die zu einem hohen Maß an vernetzten Verwaltungsleistungen führen können, werden derzeit als unzureichend angesehen, um dieses Ziel zu erreichen. Sie sind nicht ganzheitlich konzipiert und betreffen lediglich die Interaktionen zwischen öffentlichen und nicht-öffentlichen Akteuren. Ein grundlegender Wandel hin zu einer gemeinsamen Erbringung von Verwaltungsleistungen würde eine Überprüfung der etablierten Prozesse, Rollen und Interaktionen zwischen den Beteiligten erfordern. Verschiedene Wissenschaftler und Praktiker im öffentlichen Sektor gehen davon aus, dass der Einsatz der institutionellen Blockchain-Technologie die Beziehungen zwischen öffentlichen und nicht-öffentlichen Akteuren grundlegend verändern könnte. Auf den ersten Blick könnte die interorganisationale, gemeinsame Erbringung von Verwaltungsleistungen von der Nutzung der Blockchain profitieren. Diese Dissertation soll diese weit verbreitete Annahme beleuchten. Ziel dieser Arbeit ist es daher, die Auswirkungen von Blockchain auf die Beziehungen zwischen öffentlichen Verwaltungen und nicht-öffentlichen Akteuren zu belegen. Dieses Ziel wird durch die Definition von drei wesentlichen Erkenntnisbereichen verfolgt. Erstens soll in dieser Dissertation die Frage beantwortet werden, ob Blockchain geeignet ist, um New Public Governance zu ermöglichen, und es sollen Fälle ermittelt werden, in denen Blockchain möglicherweise nicht die richtige Lösung ist. Der zweite Bereich zielt darauf ab, den Status quo der bestehenden Blockchain-Implementierungen im öffentlichen Sektor empirisch zu verstehen und zu prüfen, ob sie den wichtigsten theoretischen Schlussfolgerungen entsprechen. Der dritte Bereich untersucht die sich verändernde Rolle der öffentlichen Verwaltungen, da das Blockchain-Ökosystem die Zahl der Beteiligten erheblich erhöhen kann. Entsprechende Forschungsarbeiten werden durchgeführt, um Einblicke in diese Bereiche zu gewinnen, z. B. durch die Kombination von theoretischen Konzepten mit empirischen Befunden, die Durchführung von Interviews mit Fachleuten und wichtigen Akteuren führender Blockchain-Implementierungen und die Durchführung einer umfassenden Stakeholder-Analyse mit anschließender Visualisierung der Ergebnisse. Die Ergebnisse dieser Dissertation zeigen, dass Blockchain New Public Governance in vielerlei Hinsicht unterstützen kann, während sie sich auf bestimmte Aspekte (z. B. dezentrale Steuerung), die dieses Verwaltungsparadigma ausmachen, nur wenig auswirkt. Darüber hinaus deuten die bestehenden Projekte auf Veränderungen in den Beziehungen zwischen öffentlichen Verwaltungen und nicht-öffentlichen Akteuren hin, wenn auch nicht unbedingt auf die von der New Public Governance vorgeschlagene grundlegende Veränderung. Schließlich deuten die Ergebnisse darauf hin, dass sich die Machtverhältnisse verschieben, einschließlich des abnehmenden Einflusses der öffentlichen Verwaltungen innerhalb des Blockchain-Ökosystems. Die Ergebnisse werfen Fragen zu den Governance-Modellen und zur Regulierung auf, die zur Unterstützung ausgereifter Lösungen und der weiteren Verbreitung von Blockchain für die Erbringung öffentlicher Verwaltungsleistungen erforderlich sind.
