"Währungsunion ohne Wirtschaftsunion"
(2019)
Im Mittelpunkt der vorliegenden Arbeit steht die wirtschaftspolitische Analyse der Konstruktion der Wirtschafts- und Währungsunion. Während die Geld- und Währungspolitik in Europa seit 1999 vollständig supranationalisiert ist, verbleiben zentrale Politikbereiche wie die Wirtschafts- und Finanzpolitik weiterhin in nationalstaatlicher Verantwortung. Die derzeitigen Probleme der EWWU – so die grundlegende Erkenntnis dieser Arbeit – sind v.a. darin begründet, dass die Währungsunion nicht durch eine adäquate Wirtschaftsunion ...

Determinants and Effects of Local Public Education Expenditures - an Empirical Approach
(2019-09-18)
There are many (international) debates on education and education expenditures from a political economic as well as from a scientific perspective. However, the role of German counties and local agents in Germany in general has not been analyzed from an economic perspective yet. This is the reason why my doctoral thesis investigates the role of German counties as the “forgotten” agent for the determinants and effects of local public school expenditures. This cumulative dissertation consists of three econometric papers ...

Identification of individuals and groups in a public goods experiment
(2019-07-03)
Revealing the identities of contributors has been shown to increase cooperation in public goods games. In this paper we experimentally investigate whether this finding holds true when decisions are made by groups rather than individuals. We distinguish between groups in which members can discuss face-to-face to reach a decision and groups in which members communicate via computer chat. The results confirm the positive effect of identification on cooperation among individuals. For groups, however, we only find a small ...

Voting on the threat of exclusion in a public goods experiment
(2019-04-01)
Ostracism is practiced by virtually all societies around the world as a means of enforcing cooperation. In this paper, we use a public goods experiment to study whether groups choose to implement an institution that allows for the exclusion of members. We distinguish between a costless exclusion institution and a costly exclusion institution that, if chosen, reduces the endowment of all players. We also provide a comparison with an exclusion institution that is exogenously imposed upon groups. A significant share of ...

Tipping Versus Cooperating to Supply a Public Good
(2017-02-17)
In some important multiplayer situations, such as efforts to supply a global public good, players can choose the game they want to play. In this paper we conduct an experimental test of the decision by a group with fixed membership, playing over a finite number of periods, to choose between a “tipping” game, in which every player wants to contribute to the public good provided enough other players contribute, and a prisoners’ dilemma, the classic cooperation game. In the prisoners’ dilemma, the first best outcome is ...

The choice of institutions to solve cooperation problems: a survey of experimental research
(2019-11-01)
A growing experimental literature studies the endogenous choice of institutions to solve cooperation problems arising in prisoners’ dilemmas, public goods games, and common pool resource games. Participants in these experiments have the opportunity to influence the rules of the game before they play the game. In this paper, we review the experimental literature of the last 20 years on the choice of institutions and describe what has been learned about the quality and the determinants of institutional choice. Cooperative ...

Neue Medien im Kundendialog
(BusinessFORUM, 2011)
Kundendialoge im Web 2.0 sind erheblich anspruchsvoller als konventionelle Vorgehensweisen im E-Commerce und in den allseits etablierten Online-Shops. Vom Marketing-Buzzword im Jahr 2006 ist diese Kommunikationsform nun zu einem „Must" des zeitgemäßen Marketings avanciert. Allerdings bestehen Unsicherheiten hinsichtlich der Möglichkeiten und Grenzen einer Kundenkommunikation mit den Diensten des Web 2.0. Qualifizierte Budgetentscheidungen sind daher oft schwer zu treffen. Für alle Unternehmen und Organisationen wie ...

Cultural Adaption of Hypermedia
(2012)
Culturally adapted hypermedia design attracts increasing scientific attention. Complementing the conventional human-computer interaction studies we investigate the current state of companies’ cultural adaptation of their websites. This study evaluates a sample of 215 websites with respect to design and navigational aspects. Subsequently, we discuss the possibilities of structuring hypermedia and enabling the adaptation to culturally bounded user expectations. Moreover, we introduce metrics for assessing navigational ...

Is your Perception of "Luxury" Similar to Mine? A Concept Made of Absolute and Relative Features
(2015)
Luxury is a relative feature of goods and services. Despite the many empirical studies that have been conducted, marketing scholars have not agreed on a common definition or interpretation of the term "luxury" so far. This deficit causes improper interpretations and, thus, evokes a kind of growing conceptual confusion. Additionally, the increasing interest in luxury in recent years had contributed unintentionally to the ambiguity of the term. Advertising agencies consciously or unconsciously aim to take advantage of ...
