We attempt to formulate and explain two types of self-fulfilling prophecy, called the Pygmalion effect (if a supervisor thinks her subordinates will succeed, they are more likely to succeed) and the Galatea effect (if a person thinks he will succeed, he is more likely to succeed). To this...

We investigate a multi-agent moral-hazard model where agents have expectation-based reference-dependent preferences a la Koszegi and Rabin (2006, 2007). We show that even when each agent's probability of success in a project is independent, team incentives can be optimal. Because the agents are...

This paper studies the optimal contracts in a multitask model when a principal-agent relationship is long-term. If some outcomes are unverifiable, then the contracts have to satisfy the self-enforcing condition. I characterize the optimal contract in terms of the discount rate, the cost...

This study examines the effect of the principal’s control over the agent’s behavior in a dynamic principal-agent model with hidden information. We show the condition that the agent who has a similar preference for actions as the principal dares to choose the unpreferred action when the...

We consider a model with two countries in which each government redistributes income between two types of individuals (the rich and the poor). This model shows that an increase in the mobility of individuals induces intensive tax competition across countries and lowers the level of...
