The procurement of an innovation involves motivating a research effort to generate a new idea and then implementing that idea efficiently. If research efforts are unverifiable and implementation costs are private information, a trade-off arises between the two objectives. The optimal mechanism...

The procurement of complex projects is often plagued by large cost overruns. One important reason for these additional costs are flaws in the initial design. If the project is procured with a price-only auction, sellers who spotted some of the flaws have no incentive to reveal them early. Each...

We study an incentive auction in which multiple principals bid for the exclusive services, or effort, of a single agent. Each principal has private information about her valuation for these services, and the agent has private information about his disutility of providing them. We characterize...

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...

This paper studies the problem of information revelation in a multi-stage tournament where the agents’ effort in each stage gives rise to a stochastic performance signal privately observed by the principal. The principal controls the agents’ effort incentive through the use of a feedback...

We consider a mechanism design setting in which agents can acquire costly information on their preferences as well as others'. The choice of the mechanism generates informational incentives as it affects what information is acquired before play begins. A mechanism is informationally simple if...

We consider the problem of a principal who wishes to contract with a privately informed agent and is not able to commit to not renegotiating any mechanism. That is, we allow the principal, after observing the outcome of a mechanism to renegotiate the resulting contract without cost by proposing...

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...
