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 ...

Exploring the Supply-Demand-Discrepancy of Sustainable Financial Products in Germany from a Financial Advisor’s Point of View
(2018-03-23)
Although retail investors’ interest in sustainable investment is constantly increasing, German credit unions and co-operative banks offer few sustainable financial products. The purpose of the study is to explore the current gap between supply and demand of sustainable financial investments in German retail banking from a financial advisor’s point of view. We use qualitative analysis of interviews with financial advisors based on a Grounded Theory approach with the aim to identify the key causation in the cause-effect ...

Consumer Preferences for Local Food: Testing an Extended Norm Taxonomy
(2018-04-24)
Consumer attitudes toward consuming and buying locally produced food are well studied. By contrast, the topic of consumer preferences for local food, with a special emphasis on the role of norms, still lacks empirical evidence. To study the influence of norms and morals on the intention to buy local food products, a quantitative study (N = 327) focusing on external social and internalized moral norms was conducted using the constructs of the theory of planned behavior in combination with an extended norm taxonomy and ...

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 ...

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 ...

Linking entrepreneurial orientation to firm performance in a post-socialist market context: the case of Hungary
(2016)
Entrepreneurial orientation provoked the interest of numerous scholars as well as political and administrative decision-makers. Both start-ups and already established corporate entities are increasingly persecuting new opportunities, products, and business models in order to establish superiority above their competitive environment. The tendencies evince an optimist impact of entrepreneurial orientation on business performance, namely on financial performance. Beyond the aforementioned relationship, there are impulses ...
