We analyze explicit and implicit contracts in a repeated principal-agent model with observable but only partially contractible actions of the agent. It is shown that the set of implementable actions may increase or decrease if additional actions become contractible.

Essential characteristics of corruption are (1) a reciprocity relationship between briber and public official, (2) negative welfare effects, and (3) high penalties when discovered. We separate the influences of these factors in an experiment. In a two-player game reciprocation is economically...

The paper analyzes a finitely repeated bargaining game with asymmetric information. It gives a precise characterization of the equilibrium path and the equilibrium payoffs of all sequential equilibria satisfying a weak Markov property. The method used allows for arbitrarily many different types...

The German federal government intends to introduce regular staff rotation as a precautionary measure against corruption in public administrations. To test the effectiveness of this instrument, we conduct an experiment using the bribery game by Abbink, Irlenbusch, and Renner (1999), in which...

This paper analyzes the effect of the availability of information about the payoff structure on the behavior of players in a Common-Pool Resource game. Six groups of six individuals played a complete information game, while other six groups played the same game but with no information about the...
