We assess the short-term employment effects of the introduction of a national statutory minimum wage in Germany in 2015. For this purpose, we exploit variation in the regional treatment intensity, assuming that the stronger a minimum wage ‘bites’ into the regional wage distribution, the stronger the regional labour market will be affected. In contrast to previous studies, we construct two regional bite indicators based upon detailed individual wage data from the Structure of Earnings Survey (SES) 2014 and combine it with administrative information on regional employment. Moreover, using the Socio-Economic Panel (SOEP), we are able to affirm the absence of anticipation effects and verify the assumption of a common trend in wages before the reform. In sum, we find only moderate negative effects on overall employment of about 140,000 (0.4%) jobs, which are mainly driven by a sharp decline of marginal employment (‘mini-jobs’), while we do not find pronounced significant effects for regular employment in most specifications. Our results are robust to a variety of sensitivity tests.
Digital transformation (DT) is a major challenge for traditional companies. Despite the term, DT is relatively new; its substance is not: a whole stream of research has examined the relationship between DT and firm performance with contradictory findings. Most of these studies have chosen a linear correlational approach, however, did not analyze the holistic interplay of DT dimensions, leading to firm performance. This applies especially to the mature financial services industry and the future perspectives of traditional financial service providers (FSP). Hence, it remains an open question for both research and practice what DT configurations have a positive impact on firm performance. Against this background, the aim of this exploratory study is to examine how DT dimensions are systemically connected to firm performance of incumbent FSP. Drawing on a qualitative-empirical research approach with case data from 83 FSP, we identify digital configurations along different levels of firm performance. Our findings suggest an evolution of digital configurations of FSP, leading to five empirical standard types from which only one managed to establish a profound basis of DT.

Retail banking has undergone a massive transformation in the last few years. A major aspect is changing consumer behavior. The aim of the paper is to better understand retail banking consumers regarding the impact of digitalization. Consequently, we acquired online consumer review data from Germany, the UK and US. We analyzed the data using coding techniques of grounded theory, supported by interdisciplinary literature to identify and categorize the relevant influence factors. The outcome of the paper is an integrated model of consumer decision-making in today’s retail banking along with four detailed partial models of the respective decision stages.
Fairness versus efficiency
(2018)
We investigate in a laboratory experiment whether procedural fairness concerns affect how well individuals are able to solve a coordination problem in a two-player Volunteer’s Dilemma. Subjects receive external action recommendations, either to volunteer or to abstain from it, in order to facilitate coordination and improve efficiency. We manipulate the fairness of the recommendation procedure by varying the probabilities of receiving the disadvantageous recommendation to volunteer between players. We find evidence that while recommendations improve overall efficiency regardless of their implications for expected payoffs, there are behavioural asymmetries depending on the recommendation: advantageous recommendations are followed less frequently than disadvantageous ones and beliefs about others’ actions are more pessimistic in the treatment with recommendations inducing unequal expected payoffs.
The current German start-up subsidy for unemployed individuals underwent a major reform in 2011 that altered key parameters of the program, leading to ambiguous ex ante predictions on the post-reform effectiveness of the program, making a new evaluation necessary. In our descriptive analysis, we find that participants after the reform differ significantly from pre-reform participants in terms of important characteristics and subsequent labor market performance. Our causal analysis reveals positive and sizable treatment effects on the treated regarding employment and income that are larger effects than what was estimated for the pre-reform program. Potential reasons for this are discussed.
This paper reconsiders the explanation of economic policy from an evolutionary economics perspective. It contrasts the neoclassical equilibrium notions of market and government failure with the dominant evolutionary neo-Schumpeterian and Austrian-Hayekian perceptions. Based on this comparison, the paper criticizes the fact that neoclassical reasoning still prevails in non-equilibrium evolutionary economics when economic policy issues are examined. This is more than surprising, since proponents of evolutionary economics usually view their approach as incompatible with its neoclassical counterpart. In addition, it is shown that this "fallacy of failure thinking" even finds its continuation in the alternative concept of "system failure" with which some evolutionary economists try to explain and legitimate policy interventions in local, regional or national innovation systems. The paper argues that in order to prevent the otherwise fruitful and more realistic evolutionary approach from undermining its own criticism of neoclassical economics and to create a consistent as well as objective evolutionary policy framework, it is necessary to eliminate the equilibrium spirit. Finally, the paper delivers an alternative evolutionary explanation of economic policy which is able to overcome the theory-immanent contradiction of the hitherto evolutionary view on this subject.
„If you can’t measure it, you can’t manage it.“ Dieser Slogan, der u. a. auf Peter Drucker, Henry Deming oder Robert Kaplan und David Norton zurückgehen soll, ist Ausdruck einer tiefen Überzeugung in die Notwendigkeit und den Nutzen des Performance Managements, einem Ansatz der auch die öffentliche Verwaltung erfasst und geprägt hat. Gleichzeitig impliziert er eine entscheidende Rolle von Performance Informationen. Die vorliegende Dissertation rückt das neuralgische Element Performance Information ins Zentrum des Forschungsinteresses, genauer die Verwendung von Kennzahlen.
Ausgangspunkt bildet die wissenschaftliche Beobachtung, dass Kennzahlen nicht immer und automatisch in der vom theoretischen Standpunkt aus erforderlichen und prognostizierten Art und Weise genutzt werden. Eine schlechte Implementierung des Managementansatzes oder Fehler im theoretischen Fundament sind mögliche Erklärungsansätze. Im Zuge der Analyse des Forschungsstandes ist offenkundig geworden, dass Erklärungen vor allem im organisationalen Setting und in Performance Management bezogenen Faktoren gesucht werden; ein Kennzeichen für eine eher technokratische und implementationsbezogene Perspektive auf die Verwendungsproblematik. Die aus neurowissenschaftlicher Sicht wichtige intrapersonale Ebene spielt eine ungeordnete Rolle.
In Anbetracht dessen ist auf der Grundlage neurowissenschaftlicher Erkenntnisse im Rahmen einer empirischen Untersuchung die Wirkung erfahrungsbezogener Variablen auf das Verwendungsverhalten untersucht worden. Dabei ist analysiert worden, wie Erfahrungen auf organisationaler Ebene entstehen und wie sie im Detail auf das Nutzungsverhalten wirken. Als Forschungsobjekt sind polizeiliche Führungskräfte herangezogen worden. Die Daten sind Ende 2016/Anfang 2017 online-basiert erhoben worden.
Im Ergebnis der Datenauswertung und Diskussion der Befunde sind folgende Erkenntnisse hervorzuheben:
(1) Erfahrungen beeinflussen die Verwendung von Performance Informationen. Die Art der Erfahrung mit Kennzahlen bildet dabei eine Mediatorvariable. Vor allem organisationale Faktoren, wie der Reifegrad des Performance Management Systems, wirken über den Faktor Erfahrung auf das Verwendungsverhalten.
(2) Erwähnenswert ist zudem, dass die Auseinandersetzung mit Kennzahlen sowohl den Erfahrungsschatz als auch die Nutzung von Kennzahlen positiv beeinflusst. Insgesamt haben sich die neurowissenschaftlich inspirierten Variablen als vielversprechende Erklärungsfaktoren herausgestellt.
(3) Des Weiteren hat die Arbeit bestehende Befunde abgesichert, v. a. die Wirkung des erwähnten Reifegrads. Allerdings sind auch Unterschiede aufgetreten. So büßt zum Beispiel der transformationale Führungsstil i. V. m. Art der Erfahrung seine positive Wirkung auf die Kennzahlennutzung ein.
(4) Interessant sind zudem die Ergebnisse des Labor- und Quasiexperiments. Erstmalig sind nicht zweckorientierte Verwendungsarten experimentell beobachtbar. Zudem sind neuro- und verhaltensökonomische Erklärungsansätze identifiziert und diskutiert worden, die eine Bereicherung des Forschungsdiskurses darstellen. Sie bieten eine neue Perspektive hinsichtlich des Verwendungsverhaltens und liefern Impulse für die weitere Forschung.
Für das New Public Management, in dessen Werkzeugkasten dieser Managementansatz eine Schlüsselrolle einnimmt, wiegen die Forschungsbefunde schwer. Ohne ein funktionierendes Performance Management kann das wichtige Reformziel „Wirkungsorientierung“ nicht erreicht werden. Das NPM läuft damit Gefahr, selbst Dysfunktionen zu entwickeln.
Insgesamt scheint es geboten, in der Auseinandersetzung mit Managementsystemen einen stärkeren Fokus auf intrapersonale Faktoren zu legen. Auch Verhaltensanomalien im Kontext von Management und deren Implikationen sollten näher untersucht werden. Es zeigt sich ferner, dass eine rein technokratische Sichtweise auf das Performance Management nicht zielführend ist. Folglich ist das Performance Management theoretisch wie konzeptionell fortzuentwickeln.
Die Forschungsarbeit liefert somit wichtige neue Erkenntnisse zur Verwendung von Performance Informationen und zum Verständnis von Performance Management. Vor allem erweitert sie den Forschungsdiskurs, da sie die Erklärungskraft intrapersonaler Faktoren aufgezeigt hat sowie methodisch mit dem Mixed-Method-Ansatz (Multimethod-Studie) und theoretisch mittels der Neuro- und Verhaltensökonomie neue Perspektiven hinsichtlich der Verwendungsproblematik eröffnet.
Chinas neuer langer Marsch

Negotiations between buyers and suppliers directly influence a company’s costs, revenue, and consequently its profits. The outcome of these negotiations relies heavily on the companies’ as well as the negotiators’ power position. Across three empirical articles the author demonstrates how the own power position can first be identified as well as improved and subsequently used to maximize profits in negotiations between sellers and buyers. In the first paper the sources underlying buyer and supplier power are identified and weighted. The results of the first paper show the impact of each single sources on the buyer and supplier power. The number of suppliers available for one product is by far the most important source of power for both sides. The results indicate that a higher number of suppliers leads to a better power position of the buyer and simultaneously to an inferior power position of a single supplier. The second paper aims to examine the impact of the number of suppliers on the outcome of buyer-seller-negotiations thereby considering the innovation level of the products purchased. The results of the second study which are based on real negotiation data from a German car manufacturer indicate that the number of available suppliers has a stronger impact on the negotiation outcome for innovative than for functional, less innovative products. The third paper analyzes how the ability to take the counterpart’s perspective (perspective taking ability) influences the negotiation outcome. This relationship is examined for different power positions. The results indicate that a negotiator’s high perspective taking ability leads to a more unfavorable negotiation outcome compared to low perspective taking ability. Simultaneously, high perspective taking ability causes a more positive perception of the conducted negotiation than low perspective taking ability. This contradictory effect of perspective taking ability bears the risk for buyers and suppliers to assess an unfavorable outcome as positive. Finally, the results of the papers are summarized and discussed. The dissertation concludes with implications for practice, limitations of the work, and approaches for future research.
Email tracking allows email senders to collect fine-grained behavior and location data on email recipients, who are uniquely identifiable via their email address. Such tracking invades user privacy in that email tracking techniques gather data without user consent or awareness. Striving to increase privacy in email communication, this paper develops a detection engine to be the core of a selective tracking blocking mechanism in the form of three contributions. First, a large collection of email newsletters is analyzed to show the wide usage of tracking over different countries, industries and time. Second, we propose a set of features geared towards the identification of tracking images under real-world conditions. Novel features are devised to be computationally feasible and efficient, generalizable and resilient towards changes in tracking infrastructure. Third, we test the predictive power of these features in a benchmarking experiment using a selection of state-of-the-art classifiers to clarify the effectiveness of model-based tracking identification. We evaluate the expected accuracy of the approach on out-of-sample data, over increasing periods of time, and when faced with unknown senders. (C) 2018 Elsevier B.V. All rights reserved.
Relatively little is known about the relationship between Carl Menger, founder of the Austrian school of economics, and his son, Karl Menger, the mathematician, geometer, logician, and philosopher of science, whose mathematical colloquium at the University of Vienna was essential for the development of mathematical economics. Based on Karl Menger’s diaries and correspondence, the present paper considers the development and struggles of the young Karl Menger, focusing on the years 1919–23, when Vienna was a vanquished city. We discuss the various relations within the Menger family and their significance for Karl Menger’s intellectual development. Additionally, we consider his acquaintances with economists such as Knut Wicksell, David Davidson, and Eli Heckscher as well as the younger Menger’s work in economics. We shed new light on his editorship of the second edition of his father’s Grundsätze der Volkswirtschaftslehre.

Federal Administration
(2021)
The federal administration is significantly small (around 10 percent of all public employees). This speciality of the German administrative system is based on the division of responsibilities: the central (federal) level drafts and adopts most of the laws and public programmes, and the state level (together with the municipal level) implements them. The administration of the federal level comprises the ministries, subordinated agencies for special and selected operational tasks (e.g. the authorisation of drugs, information security and registration of refugees) in distinct administrative sectors (e.g. foreign service, armed forces and federal police). The capacity for preparing and monitoring government bills and statutory instruments is well developed. Moreover, the instruments and tools of coordination are exemplary compared with other countries, although the recent digital turn has been adopted less advanced than elsewhere.
This chapter describes the most prominent public management reform trajectories in German public administration over the past decades since unification. In the 1990s, the New Steering Model emerged as a German variant of the NPM. Since the mid-2000s, local governments in Germany have been subjected to a mandatory reform of their budgeting and accounting system known as the New Municipal Financial Management reforms. Both reforms have led to a substantial change in terms of internal decentralisation, customer orientation, transparency in resource use and the financial situation of administrative bodies. But the emerging reform patterns and their impacts have not replaced the dominance of a strong legalist culture with hierarchical, centralised control. However, in the course of the reforms, a citizen-customer perspective, more participation of citizens and limited application of new management instruments have been accommodated within the persisting bureaucratic system.
Over the last decades, Better Regulation has become a major reform topic at the federal and—in some cases—also at the Länder level. Although the debate about improving regulatory quality and reducing unnecessary burdens created by bureaucracy and red tape date back to the 1960s and 1970s, the introduction by law in 2006 of a new independent institutionalised body for regulatory control at the federal level of government has brought a new quality to the discourse and practice of Better Regulation in Germany. This chapter introduces the basic features of the legislative process at the federal level in Germany, addresses the issue of Better Regulation and outlines the role of the National Regulatory Control Council (Nationaler Normenkontrollrat—NKR) as a ‘watchdog’ for compliance costs, red tape and regulatory impacts.
Although German bureaucracy is typically categorised as Weberian, a clear distinction between politics and administration has never been a defining characteristic of the German political-administrative system. Many close interrelations and interactions between elected politicians and appointed civil servants can be observed at all levels of administration. Higher-ranking civil servants in Germany are used to and generally appreciate the functional politicisation of their jobs, that is their close involvement in all stages of the policy process, from policy formation, goal definition, negotiation within and outside government to the implementation and evaluation of policies. For top positions, therefore, a class of ‘political civil servants’ is a special feature of the German system, and obtaining ‘political craft’ has become an important part of the learning and job experience of higher-ranking civil servants.
German Public Administration
(2021)
The international community of public administration and administrative sciences shows a great interest in the basic features of the German administrative system. The German public administration with its formative decentralisation (called: administrative federalism) is regarded as a prime example of multilevel governance and strong local self-government. Furthermore, over the past decades, the traditional profile of the German administrative system has significantly been reshaped and remoulded through reforms, processes of modernisation and the transformation process in East Germany. Studies on the German administrative system should focus especially on
key institutional features of public administration;
changing relationships between public administration, society and the private sector;
administrative reforms at different levels of the federal system; and
new challenges and modernisation approaches, such as digitalisation, open government and better regulation.
Human resource management (HRM) reform has not been the focus of attention in Germany despite its obvious relevance for effective policy implementation. Although there is a general trend worldwide towards convergence between public and private HRM strategies and practices, management of the workforce in German public administration still remains largely traditional and bureaucratic. This chapter describes and analyses German practices regarding the central functions and elements of HRM such as planning, recruitment, training and leadership. Furthermore, it explores the importance and contribution of public service motivation, performance-related pay and diversity management in the context of German practices. The chapter concludes by highlighting some of the major paradoxes of German public HRM in light of current challenges, such as demographic change, digital transformation and organisational development capabilities.
The chapter analyses recent reforms in the multilevel system of the Länder, specifically territorial, functional and structural reforms, which represent three of the most crucial and closely interconnected reform trajectories at the subnational level. It sheds light on the variety of reform approaches pursued in the different Länder and also highlights some factors that account for these differences. The transfer of state functions to local governments is addressed as well as the restructuring of Länder administrations (e.g. abolishment of the meso level of the Länder administration and of single-purpose state agencies) and the rescaling of territorial boundaries at county and municipal levels, including a brief review of the recently failed (territorial) reforms in Eastern Germany.
The German system of public sector employment (including civil servants and public employees) qualifies as a classical European continental civil service model moulded in traditional forms of a Weberian bureaucracy. Its features include a career-based employment system with entry based on levels of formal qualification. Coordinated by legal frames and centralised collective bargaining, the civil service is, at the same time, decentralised and flexible enough to accommodate regional differences and societal changes. In comparison, the civil service system stands out for its high degrees of professionalism and legal fairness with low levels of corruption or cronyism.
In diesem Artikel werden die Voraussetzungen für eine erfolgreiche Digitalisierung der öffentlichen Verwaltung diskutiert. Dabei liegt der Fokus auf den internen Verwaltungsprozessen sowie auf der Kommunikation und Koordination innerhalb und zwischen Behörden. Zur richtigen Anlage eines digitalen Organisationswandels sind vor allem das Personalmanagement, die Organisationsform des Veränderungsprozesses sowie der Technologieeinsatz von zentraler Bedeutung.
Die Digitalisierung der öffentlichen Leistungserbringung für die Bürger bildet gegenwärtig einen Schwerpunkt der Modernisierungsaktivitäten in Staat und Verwaltung. Hinsichtlich der digitalen Informationsbereitstellung hat es zwar deutliche Fortschritte gegeben, insgesamt zeigt sich jedoch eine allenfalls moderate „E-Government-Performanz“ bei der digitalen Kommunikation zwischen Verwaltung und Bürgern sowie bei Transaktionen, d. h. der medienbruchfreien Abschließbarkeit von Verwaltungsvorgängen. Als wesentliche Gründe für die ernüchternde Bilanz der lokalen Verwaltungsdigitalisierung sind neben technischen, rechtlichen, finanziellen und personellen Barrieren insbesondere politische und institutionelle Hürden zu nennen. Viele Probleme sind zudem auch bei E-Government-Funktionen (z. B. der Online-Formulare oder elektronischen Bezahlmöglichkeiten) zu verzeichnen. Positiv schneidet dagegen die elektronische Terminvergabe ab, die in den Bürgerämtern zu wesentlichen Prozess- und Serviceverbesserungen geführt hat. Allerdings sind neben positiven Effekten, wie beispielsweise schnelleren Bearbeitungszeiten und kürzeren Wartezeiten, auch dysfunktionale Digitalisierungseffekte zu verzeichnen, wie erhöhter Arbeitsstress aufgrund eines gestiegenen Kommunikationsaufkommens (v. a. durch Email) und der damit einhergehenden Verlagerung des Arbeitsaufkommens vom Frontoffice ins Backoffice.
Digitale Transparenz
(2020)
Transparenz ist kein neuer Begriff, sondern im Zusammenhang mit Rechtsstaatlichkeit, Gewaltenteilung oder Demokratie schon lange Gegenstand politischer Theorie und Praxis. Transparenz bedeutet, dass Akteure, wie etwa Verwaltungsorganisationen, relevante Informationen über ihre Entscheidungsprozesse, Funktionsweisen und Performanz gegenüber externen Akteuren offenlegen. Für politische und Verwaltungsakteure gewinnt Transparenz im Zuge der Digitalisierung an zusätzlicher Bedeutung. Moderne Informations- und Kommunikationstechnologien vereinfachen Transparenzschaffung, sowohl in der Geschwindigkeit als auch im Ressourceneinsatz. Sie können so zu neuen Formen und einer neuen Qualität von Transparenz in Politik und Verwaltung beitragen. Transparenz- und Datenportale oder Bürgerhaushalte sind digitale Instrumente, die diesem Zweck dienen sollen. Ob digitale Transparenz politische und administrative Prozesse tatsächlich effizienter, effektiver und durchsichtiger macht und Bürger*innen diese dadurch besser verstehen, ist jedoch eine offene Frage.
This master’s thesis examined the internet content regulation in Germany from a perspective of Public-Private Partnerships. In the European Union, there has been a latest trend of initiatives aiming for combating illegal content online under the self-regulatory regime. Yet, concerns of this trend were that transparency cannot be ensured properly to safeguard the freedom of expression, and that the private intermediaries are not able to carry out effective regulation under the non-binding regulatory process. Due to these issues, Germany has legislated the Network Enforcement Act in 2017. This thesis used Mixed Methods within a Case Study Research, in order to identify the PPP type of the NetzDG, and to understand its link on transparency and effectiveness, as well as the relationship of these two dimensions. By taking an Exploratory Sequential Design, the German internet content regulation under the NetzDG was explored to understand its co-regulatory regime and to develop an instrument to measure the aspects of transparency and effectiveness. Then, the three big social media platforms, YouTube, Twitter, and Facebook, were examined according to the developed indicators. This thesis concluded as follow: First, the enactment of the NetzDG brought the shift of the regulatory paradigm from the self-regulatory to the co-regulatory. Yet, the actor-inclusive institutional arrangement of the NetzDG did not successfully result in the actual inclusion of actors in decision-making, but only improved the result transparency in the disclosure of take-down actions. Second, the level of effective regulation was not consistent across the three social media platforms under this regime. Despite these limitations, this study showed that the transparency and the effectiveness of the social media platforms’ implementation gradually improved together, instead of having a negative correlation to one another.
Corporate venture capital (CVC) units help their ventures flourish by offering value-adding services. Effective CVC initiatives offer services that help ventures design, implement, and manage activities to create and capture value. Our qualitative multiple case study across 26 CVC units reveals a comprehensive set of value creation and value capture services that these units offer, configured in any of four different ways to provide tailor-made support for specific venture needs and sponsor strategic goals.
User Experience (UX) describes the holistic experience of a user before, during, and after interaction with a platform, product, or service. UX adds value and attraction to their sole functionality and is therefore highly relevant for firms. The increased interest in UX has produced a vast amount of scholarly research since 1983. The research field is, therefore, complex and scattered. Conducting a bibliometric analysis, we aim at structuring the field quantitatively and rather abstractly. We employed citation analyses, co-citation analyses, and content analyses to evaluate productivity and impact of extant research. We suggest that future research should focus more on business and management related topics.
Social networking sites (SNSs) are central to social interaction and information sharing in the digital age. However, consuming social information on SNSs invites social upward comparisons with highly socially desirable profile representations, which easily elicits envy in users and leads to unfavorable behaviors on SNSs. This in turn can erode the subjective well-being of users and the sustainability of the SNS platform. Therefore, this paper seeks to develop a better theoretical understanding of how users respond to envy on SNSs. We review literature on envy in offline interactions to derive three behavioral strategies to reduce envy, which we then transfer to the SNS context (self-enhancement, gossiping, and discontinuous intention). Further, we propose a research model and examine how culture, specifically individualism-collectivism, affects the relationship between envy on an SNS and the three strategies. We empirically test the variance-based structural equation model through survey data collected of Facebook users from Germany and Hong Kong. Our findings provide first insights into the link between envy on SNSs, related behavioral strategies and the moderating role of individualism for self-enhancement.

Existing factories face multiple problems due to their hierarchical structure of decision making and control. Cyber-physical systems principally allow to increase the degree of autonomy to new heights. But which degree of autonomy is really useful and beneficiary? This paper differentiates diverse definitions of autonomy and approaches to determine them. Some experimental findings in a lab environment help to answer the question raised in this paper.

Das Ziel der vorliegenden Dissertation war es herauszuarbeiten, ob Nachhaltigkeitsbewusstsein den Konsum von Luxusgütern beeinflusst und ob verschiedene Moderatoren einen Einfluss auf diesen Zusammenhang ausüben. Das Nachhaltigkeitsbewusstsein wurde dabei basierend auf dem von Balderjahn et al. (2013) entwickelten Consciousness-for-sustainable-consumption-Modell durch die ökologische, soziale und die ökonomische Nachhaltigkeit sowie ergänzend durch das Tierschutzbewusstsein und Bewusstsein für lokale Produktion repräsentiert. Als Moderatoren dienten das Streben nach sozialer Anerkennung und Prestige, Materialismus, Hedonismus und Traditionsbewusstsein. Für die Aufdeckung möglicher Zusammenhänge zwischen den verschiedenen Dimensionen der Nachhaltigkeit und Luxuskonsum wurde eine Prädiktorenanalyse durchgeführt. Moderatorenanalysen offenbarten zusätzlich, ob ein Einfluss der verschiedenen Moderatoren auf die einzelnen Zusammenhänge vorlag. Die Untersuchung zeigte, dass jeweils das Umweltbewusstsein, das Bewusstsein für genügsamen Konsum sowie das Bewusstsein für schuldenfreien Konsum als Teil der ökonomischen Nachhaltigkeit und das Tierschutzbewusstsein einen Einfluss auf den Luxuskonsum ausüben. Darüber hinaus konnten insgesamt sieben Einflüsse durch die verschiedenen Moderatorvariablen auf die unterschiedlichen Zusammenhänge zwischen den Nachhaltigkeitsdimensionen und Luxuskonsum aufgedeckt werden.
Firms engage in forecasting and foresight activities to predict the future or explore possible future states of the business environment in order to pre-empt and shape it (corporate foresight). Similarly, the dynamic capabilities approach addresses relevant firm capabilities to adapt to fast change in an environment that threatens a firm’s competitiveness and survival. However, despite these conceptual similarities, their relationship remains opaque. To close this gap, we conduct qualitative interviews with foresight experts as an exploratory study. Our results show that foresight and dynamic capabilities aim at an organizational renewal to meet future challenges. Foresight can be regarded as a specific activity that corresponds with the sensing process of dynamic capabilities. The experts disagree about the relationship between foresight and sensing and see no direct links with transformation. However, foresight can better inform post-sensing activities and, therefore, indirectly contribute to the adequate reconfiguration of the resource base, an increased innovativeness, and firm performance.

This dissertation examines the activity of knowledge sharing by public employees in the workplace. Building on the Rubicon model of human behavior formation, I use a threefold approach to analyze the knowledge-sharing process: public employees’ motivation to share knowledge, their intention to share, and knowledge sharing behavior as such. The first article maps the knowledge-sharing behavior of public employees. It builds a typology of behavioral patterns and shows that public employees mainly share their knowledge responsively and directly with a knowledge receiver rather than an information medium. The second article elaborates on the construct of knowledge-sharing motivation and develops a scale to measure this kind of work motivation in a selective and domain-specific way. Data from three studies indicate three dimensions of knowledge-sharing motivation, namely appreciation, growth and altruism, and tangible rewards. Based on these dimensions, the third article analyzes whether the satisfaction of public employees’ underlying needs can foster ther knowledge-sharing intention. The study indicates that both tested treatments (appreciation by co-workers, benefits in a performance appraisal) positively affect knowledge-sharing intention if it is explicit knowledge that ought to be shared. However, no effects of either treatment can be found if implicit knowledge is shared. Hence, to foster sharing of explicit knowledge, the analyzed motivation-enhancing rewards can be used in public management practice. To enhance implicit knowledge sharing, ability- and opportunity-enhancing management instruments are discussed. All in all, this dissertation integrates a micro-level perspective on human knowledge sharing into a meso-level perspective on organizational knowledge management. It adds to the literature on workplace behaviors of public employees and knowledge management and aims to incorporate knowledge sharing and management into the public administration and management literature.
Die Gesundheitswirtschaft in Deutschland steht vor zahlreichen Veränderungen in ihrem Umfeld. Dabei mangelt es der Krankenhauslandschaft an ärztlichem Personal. Es fehlt insbesondere an Arztstunden bei zugleich steigendem Bedarf an medizinischen Leistungen. Der demografische Wandel, Abwanderung ins Ausland (z. B. in die Schweiz) und Extrapolationen wie Feminisierung des Arztberufs und der Wertewandel respektive Generationenforschung begünstigen diese
Entwicklung. Zudem wird der Arbeitsplatz Krankenhaus zunehmend als unattraktiv von zukünftigen Arbeitnehmerkohorten angesehen. Nachwuchsärzte entscheiden sich bereits im Studium vermehrt gegen die kurative Medizin beziehungsweise gegen eine medizinisch-klinische Tätigkeit. Ein virulentes Beschaffungsproblem zeichnet sich ab, das es zu lösen gilt.
Das Forschungsziel ist die Entwicklung eines ganzheitlichen strategischen Lösungsansatzes mit marktorientierter Akzentuierung für den Arbeitgeber Krankenhaus. Dabei wird das Krankenhaus als wissens- und kompetenzintensive Dienstleistungsorganisation definiert. Employer Branding stellt den Bezugsrahmen eines marktorientierten Personalmanagements dar. Ein forschungstheoretischer Unterbau wird durch strategische Managementansätze integriert. Employer Branding schlägt die Brücke vom Market-based View zum Competence-based View und ist Markenmanagement im Kontext des strategischen Personalmanagements. In der vorliegenden Arbeit wird ein holistischer Bezugsrahmen vorgestellt, der die Wirkungszusammenhänge respektive Employer Branding darstellt. Das Herzstück ist die Employer Value Proposition, die auf der Markenidentität der Organisation basiert. Ziel des Employer Branding Ansatzes ist es, unter anderem eine präferenzerzeugende Wirkung im Prozess der Arbeitsplatzwahl sicherzustellen.
Die Zielrichtung und die Erkenntnis-Interessen erfordern einen breit angelegten Forschungsansatz, der qualitative und quantitative Methoden kombiniert. Ziel der leitfadengesteuerten Tiefeninterviews (exploratives Studiendesign) ist es, bestehende und noch zu entwickelnde Kompetenzstärken der Krankenhausorganisationen zu identifizieren. Bei der Stichprobe handelt es sich um ein „Typical Case Sampling“ (N=12). Defizitäre Befunde, welche Werte und Attraktivitätsfaktoren bei angehenden Ärzten ausgeprägt sind, werden bestätigt. In der Krankenhauslandschaft wird eine fragmentarische und reaktive Herangehensweise identifiziert, die die erfolgreiche Rekrutierung von qualifiziertem Krankenhauspersonal erschwert.
Durch die qualitative Marktforschung werden Anforderungen des Marktes – also zukünftiges, ärztliches Krankenhauspersonal – auf faktorenanalytischer Basis analysiert. Die Stichprobe (N=475) ist isomorph. Dabei wird der Prozess der Einstellungsbildung in das neobehavioristische Erklärungsmodell des Käuferverhaltens eingeordnet. Die Vereinbarkeit von Beruf, Karriere und Familie sowie die betriebliche Kinderbetreuung werden als Schlüsselkomponenten erkannt.
Wichtigste Arbeitswerte in Bezug auf einen attraktiven Arbeitgeber sind Verlässlichkeit, Verantwortung und Respekt. Diese Komponenten haben kommunikativen Nutzen und Differenzierungskraft. Schließlich bewerten Bewerber ein Krankenhaus positiver im Prozess der Arbeitsplatzwahl, je mehr die Werte des potentiellen Arbeitnehmers mit dem Werteprofil der Person übereinstimmen (Person-Organisation Fit).
Krankenhausorganisationen, die den Employer Branding Ansatz implementieren und als Chance zur Definition ihrer Stärken, ihrer Vorzüge und ihres Leistungsangebots als Arbeitgeber annehmen, rüsten sich für das verstärkte Werben um Jungmediziner. Schließlich setzt Employer Branding als marktorientierter Strategieansatz intern und extern Kräfte frei, die Differenzierungsvorteile gegenüber anderen Arbeitgebern bringen. Dabei hat Employer Branding positive Auswirkungen auf den Human Ressource-Bereich entlang der Wertschöpfungskette und mindert das gesamtwirtschaftliche Problem.

Negotiations have become a central aspect of managerial life and influence a company’s profit significantly. This is why organizations generally endeavor to increase their negotiation performance. Over the last decades, besides other factors, research found goal setting to be one of the best predictor of negotiation outcomes. Given the extent and complexity of multi-issue business negotiations, profit optimizing by means of improving a company’s goal setting has a great deal of potential. However, developing goal setting strategies before the actual negotiation is still rather uncommon in business practice. In order to provide professionals with empirical guidance, this work aims at investigating three steps for the development and effective management of goal setting strategies for business negotiations. Therefore, this dissertation contains three papers, each one dealing with one specific step. The first paper explores the characterization of social and economic outcomes in different business relationship types at the beginning of the relationship and the development of these outcomes toward the actual status quo. The second paper takes the number of goals into account for goal setting strategies. This paper uses the two dimensions goal scope and goal difficulty to investigate the relevance and potentials of combining different level of these dimensions in multi-issue negotiations. Therefore, a large experiment was conducted measuring the impact on individual and joint negotiation outcomes, and the impasse rate. The third paper analyzes the type and orientation of negotiation goals. When the set of negotiation issues has an integrative potential, the opportunity to increase the joint gains arises. To what extent negotiators pursue the integrative potential depends largely on their goal orientation. A quantitative analysis with practitioners was used to examine the influence that business negotiations’ situative and organizational factors have on the negotiators’ goal orientation. The dissertation closes with implications for practice, limitations of the work, and ideas for future research.
This paper challenges the solely rational view of the scenario technique as a strategy and foresight tool designed to cope with uncertainty by considering multiple possible future states. The paper employs an affordance-based view that allows for the identification and structuring of hidden, emergent attributes of the scenario technique beyond the intended ones. The suggested framework distinguishes between affordances (1) that are intended by the organization and relate to its goals, (2) that emergently generate organizational benefits, and (3) that do not relate to organizational but individual interests. Also, constraints in the use of scenarios are discussed. Affordance theory’s specific lens shows that the emergence of such attributes depends on the users’ specific intentions.
