We present a field experiment to assess the effect of own and peer wage variations onactual work effort of employees with hourly wages. Work effort neither reacts to anincrease of the own wage, nor to a positive or negative peer comparison. This resultseems at odds with numerous laboratory...

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...

We experimentally study the effect of asymmetry on cooperation in a 40 period prisoner's dilemma game in fixed partner design. We distinguish between a high and low payoff symmetric prisoner's dilemma and an asymmetric game combined out of both symmetric ones. Asymmetry significantly decreases...

Does probation pay a double dividend? Society saves the cost of incarceration, and convicts preserve their liberty. But does probation also reduce the risk of recidivism? In a meta-study we show that the field evidence is inconclusive. Moreover it struggles with an identification problem: those...

Broken Windows: the metaphor has changed New York and Los Angeles. Yet it is far from undisputed whether the broken windows policy was causal for reducing crime. In a series of lab experiments we show that first impressions are indeed causal for cooperativeness in three different institutional...

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...

This paper presents a new perspective on the nature of fairness in bargaining by using verbal data from spontaneous team discussions and written statements on decision motives. Systematic content analysis proves a valuable source for providing new insights. The nature of fairness can be viewed...

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 subject's...
