In a multi-agent setting, individuals often compare own performance with that of their peers. These comparisons influence agents incentives and lead to a noncooperative game, even if the agents have to complete independent tasks. I show that depending on the interplay of the peer effects, agents...

The paper studies a model of delegated search. The distribution of search revenues is unknown to the principal and has to be elicited from the agent in order to design the optimal search policy. At the same time, the search process is unobservable, requiring search to be self-enforcing. The two...

A standard tournament contract specifies only tournament prizes. If agents' performance is measured on a cardinal scale, the principal can complement the tournament contract by a gap which defines the minimum distance by which the best performing agent must beat the second best to receive the...

Previous work on moral-hazard problems has shown that, under certain conditions, bonus contracts create optimal individual incentives for risk-neutral workers. In our paper we demonstrate that, if a firm employs at least two workers, it may further bene.t from combining worker compensation via a...

Drawing on the proposer-responder game examined by Andreoni, Harbaugh, and Vesterlund (2003), I experimentally test four variations of a principal-agent relationship with fixed pay and real effort. Depending on the treatment, the principal can voluntarily, but at her own expense, (1) only reward...

We re-examine the role of managers in preventing free riding when team inputs are not observable. Holmström (1982) shows that managers are necessary due to the team's lack of static incentives to implement budget-breaking group punishments. We ask whether the team can break its own budget in a...

We show that contracting in agency with voluntary participation may involve incentives for the agent's abstention. Their provision alters the optimality criteria in the principal's decision-making, further distorts the mechanism, and may lead to breakdown of contracting in circumstances where...

In a laboratory experiment with 754 participants, we study the canonical one-shot moral hazard problem, comparing treatments with unobservable effort to benchmark treatments with verifiable effort. In our experiment, the players endogenously negotiate contracts. In line with contract theory, the...
