This dissertation extends the understanding of asymmetric group behavior in the provision of public goods. Previous studies, using an asymmetric framework, have so far focused on situations where all players profit form the social optimum. The discussion in the first paper breaks with this...

We present an experiment on voluntary contributions to a public good. The game has a dominant strategy solution in the interior of the strategy space. In the experiment we observe significant over-contribution. This result is similar to those of the typical corner solution experiments. --...

We study the robustness of reputation management systems against distortions in rating behavior. In a laboratory trust experiment with reputation management, we mimic a positive bias by exclusively offering the option to rate positively or to give no rating. As predicted by theoretical...

We introduce a simple game-theoretical model that captures the main aspects of the repeated interaction between an issuer and a credit-rating agency. It involves up-front payments of issuer-fees and direct publication of requested ratings. Due to pecuniary injuries for untruthful ratings, the...

In a public-good experiment with heterogeneous endowments, we investigate if and how the contribution level as well as the previously observed "fair-share" rule of equal contributions relative to one's endowment (Hofmeyr et al., 2007; Keser et al., 2014) may be influenced by minimum-contribution...

Since Mancur Olson's “Logic of collective action” it is common conviction in social sciences that in large groups the prospects of a successful organization of collective actions are rather bad. Following Olson's logic, the impact of an individual's costly contribution becomes smaller if the...

We study the impact of information on the effectiveness of a taking frame in the context of charitable giving. In our laboratory experiment, either the decision maker (giving frame) or the recipient (taking frame) receives an endowment. In both cases, the decision maker can freely decide the...

The objective of this paper is to look into the probability that, given the choice, corporate groups would opt for taxation on a consolidated basis. Consolidation would allow them to offset losses crossborder but remove the opportunity to exploit international tax-rate differentials between...

We investigate the formation of market prices in a new experimental setting involving multi-period call-auction asset markets with state-dependent fundamentals. We are particularly interested in two informational aspects: (1) the role of traders who are informed about the true state and/or (2)...
