We focus on the role that the transmission of information between a multilateral (the IMF) and a country has for the optimal design of conditional reforms. Our model predicts that when agency problems are especially severe, and/or IMF information is valuable, a centralized control is indeed...

Should principals explain and justify their evaluations? In this paper the principal's evaluation is private information, but she can provide justification by sending a costly cheap-talk message. I show that the principal explains her evaluation to the agent if the evaluation turns out to be...

This paper studies the effect of disclosing conflicts of interests on strategic communication when the sender has lying costs. I present a simple economic channel under which such disclosure often leads to more biased messages. This hurts receivers who are naive or delegate their choice while...

The marginal cost of effort often increases as effort is exerted. In a dynamic moral hazard setting, dynamically increasing costs create information asymmetry. This paper characterizes the optimal contract and helps explain the popular yet thus far puzzling use of non-linear incentives, for...

I present a model in which a principal selects one among many agents to develop a project and influences the agent's ex post level of effort not by outcome-contingent rewards, but by the choice of the project's mission. The closer the project's mission to the agent's preferred mission, the...

An auction is externality-robust if unilateral deviations from equilibrium leave the other bidders' payoffs unaffected. The equilibrium and its outcome will then persist if certain types of externalities arise between bidders. One example are externalities due to spiteful preferences, which have...

In many contracting settings, actions costly to one party but with no direct benefits to the other (money-burning) may be part of the explicit or implicit contract. A leading example is bureaucratic procedures in an employer-employee relationship. We study a model of delegation with an informed...
