This paper analyzes the efficiency of team production when agents exhibit other regarding preferences. It is shown that full efficiency can be sustained as an equilibrium through a budget-balancing mechanism that punishes some randomly chosen agents if output falls short of efficient level but...

Incentives often fail in inducing economic agents to engage in a desirable activity; implementability is restricted. What restricts implementability? When does re-organization help to overcome this restriction? This paper shows that any restriction of implementability is caused by an identifi...

We characterize optimal incentive contracts in a moral hazard framework extended in two directions. First, after effort provision, the agent is free to leave and pursue some ex-post outside option. Second, the value of this outside option is increasing in effort, and hence endogenous. Optimal...

In this paper, we ask under what conditions norms can enhance welfare by mitigating moral hazard in income insurance. We point out a particular role of norms, namely to compensate for insurers' difficulties in monitoring the behavior of insured individuals. Thus, the functioning of social norms...
