Tournament incentives prevail in labor markets, in particular with respect to promotions. Yet, it is often unclear to competitors how many winners there will be or how many applicants compete in the tournament. While it is hard to measure how this uncertainty affects work performance and...

Customary law has been criticized from very different angles. Rational choice theorists claim that what looks like custom is nothing but self-interest. Positivists doubt that anything beyond consent assumes the force of law. In this paper, we adopt an experimental approach to test these claims....

Over the last 25 years, more than a hundred dictator game experiments have been published. This meta study summarizes the evidence. Exploiting the fact that most experiments had to fix parameters they did not intend to test, in multiple regression the meta study is able to assess the effect of...

This paper studies how participation in decision procedures affects people’s reactions to the deciding authority. In our economic experiment, having voice, i.e., the opportunity to state one’s opinion prior to a decision, significantly increases subordinates’ subsequent kindness towards...

Apparently judges' decisions are not motivated by maximizing their own profit. The literature uses two strategies to explain this observation: judges care about the long‐term monetary consequences for themselves, or individuals who are more strongly motivated by the common good self‐select...

The Coase theorem posits: If [1] property rights are perfect, [2] contracts are enforceable, [3] preferences are common knowledge, and [4] transaction costs are zero, then the initial allocation of property rights only matters for distribution, not for efficiency. In this paper we claim that...

In modern societies more and more people interact with strangers in one-shot situations. In these situations it might be difficult to trust others. Yet, trust is an essential component of most economic interactions. In this paper (in a one-shot situation) an impartial third party can reward...

Both in the field and in the lab, participants frequently cooperate, despite the fact that the situation can be modelled as a simultaneous, symmetric prisoner’s dilemma. This experiment manipulates the payoff in case both players defect, and explains the degree of cooperation by a combination...

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...

In modern elections, ideologically motivated candidates with a wealth of information about individual voters and sophisticated campaign strategies are faced by voters who lack awareness of some political issues and are uncertain about the exact political positions of candidates. We study to what...
