Numerous laboratory experiments show that workers reciprocate to high wages with high effort, when there is perfect information on the surplus created. Recent field experiments, however, suggest that trust and reciprocity may be lower or absent when the information is incomplete. We report a...

In spring 2000, the British government auctioned off licences for Third Generation mobile telecommunications services. In the preparation of the auction, two designs involving each a hybrid of an English and a sealed-bid auction were suggested by the government: a discriminatory and a uniform...

Experimentally observed deviations of behavior from game theoretic predictions suggest that fairness does influence decision making. Fairness in the sense of equality has become an essential element of economic models aiming at explaining actual behavior (cf. Fehr and Schmidt, 1999; Bolton and...

This paper experimentally explores group decision-making in a two-player power-to-take game. Discussions preceding group decisions are video taped and analyzed. Each subject first earns an income in an individual effort task preceding the game. The game consists of two stages. First, one group...

This paper contributes to the ongoing methodological debate on context-free versus in-context presentation of experimental tasks. We report an experiment using the paradigm of a bribery experiment. In one condition, the task is presented in a typical bribery context, the other one uses abstract...

When using the strategy method in ultimatum bargaining, many researchers ask responders for the minimal acceptable offer only implicitly assuming strategies to be monotone. Recent research has shown, however, that subjects decline disadvantageous and advantageous proposals. We report on an...

A central concern in health economics is to understand the influence of commonly used physician payment systems. We introduce a controlled laboratory experiment to analyze the influence of fee-for-service (FFS) and capitation (CAP) payments on physicians' behaviour. Medical students decide as...

Psychological game theory can provide rational-choice-based framing effects; frames influence beliefs, beliefs influence motivations. We explain this theoretically and explore empirical relevance experimentally. In a 2×2 design of one-shot public good games we show that frames affect...
