We investigate the intrinsic motivation of individuals to report, and thereby sanction, fellow group members who lie for personal gain. We further explore the changes in lying and reporting behavior that result from giving individuals a say in who joins their group. We find that enough...

We show that establishing an internal labor market by offering combined contracts across hierarchy levels strictly dominates external recruitment when workers are homogeneous. The reason is that only an internal labor market can exploit higher tier rents for incentive provision on lower tiers....

We analyze optimal contracts in a hierarchy consisting of a principal, a supervisor and an agent. The supervisor is either neutral or altruistic towards the agent, but his preferences are private information. In a model with two supervisor types, we find that the optimal contract may be very...

We consider the problem of an employer who has to choose whether to reemploy agents with a positive track record or agents who were unsuccessful. While previously successful managers are likely to be of high ability, they have also accumulated wealth and will be harder to motivate in the future....

I consider a repeated principal-agent model with moral hazard, in which the agent has βδ-preferences, which are widely used to capture time-inconsistency. I analyze the case where the agent is sophisticated in the sense that he is fully aware of his inconsistent discounting. I characterize the...

Classic financial agency theory recommends compensation through stock options rather than shares to counteract excessive risk aversion in agents. In a setting where any kind of risk taking is suboptimal for shareholders, we show that excessive risk taking may occur for one of two reasons: risk...

This study investigates the extent to which gender differences in choosing to enter competitive tournaments are due to women's lower taste for competition or differences in confidence. We examine three types of confidence and find that confidence measured by expected ranking is the most...

We present a new partial equilibrium theory of price adjustment, based on consumer loss aversion. In line with prospect theory, the consumers’ perceived utility losses from price increases are weighted more heavily than the perceived utility gains from price decreases of equal magnitude. Price...

Competition among firms has been suggested to reflect the ruthless logic of Darwinian selection: a free market is a struggle for survival, in which successful firms survive and unsuccessful ones die. This view appears to bolster three pillars of neoclassical economics: (1) that economic actors...
