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...

We analyze the contracting problem of a principal who faces an agent with private information and cannot commit to not renegotiating a chosen contract. We model this by allowing the principal to propose new contracts any number of times after observing the contract choice of the agent. We...

We analyze the problem of a buyer who purchases a long-term project from one of several suppliers. A changing state of the world influences the costs of the suppliers. Complete contracts conditioning on all future realizations of the state are infeasible. We show that contractual incompleteness...

We investigate how workers' performance is affected by the timing of wages in a real-effort experiment. In all treatments agents earn the same wage sum but wage increases are distributed differently over time. We find that agents work harder under increasing wage profiles if they do not know...

We compare evaluations of employee performance by individuals and groups of supervisors, analyzing a formal model and running a laboratory experiment. The model predicts that multi-rater evaluations are more precise than single-rater evaluations if groups rationally aggregate their signals about...
