Advantageous (or propitious) selection occurs when an increase in the premium of an insurance contract induces high-cost agents to quit, thereby reducing the average cost among remaining buyers. Hemenway (1990) and many subsequent contributions motivate its advent by differences in risk-aversion...

Before embarking on a project, a principal must often rely on an agent to learn about its profitability. We model this learning as a two-armed bandit problem and highlight the interaction between learning (experimentation) and production. We derive the optimal contract for both experimentation...

Trust between parties should drive the negotiation and design of contract: if parties did not trust each others' reaction to unplanned events, they might agree to pay higher costs of negotiation to complete contracts. Using a unique sample of U.S. principal-agent consulting contracts and a...

We study the effects of overconfidence in a two-period investment-decision agency setting. Under common priors, agent risk aversion implies inefficiently low first-period investment. In our model, principal and agent disagree about the profitability of the investment decision conditional on a...

In many countries, lenders are not permitted to use information about past defaults after a specified period of time has elapsed. We model this provision and determine conditions under which it is optimal. We develop a model in which entrepreneurs must repeatedly seek external funds to finance a...

How do parties motivate candidates to exert effort in closed-list elections? If each candidate's primary goal is winning a seat, then those in safe and hopeless list positions have weak incentives to campaign. We present a model in which (i) candidates care about both legislative seats and the...

We analyze a multitasking model with a verifiable routine task and a skill-dependent activity characterized by moral hazard. Contracts negotiated by firm/employee pairs follow from Nash bargaining. High- and low-skilled employees specialize, intermediate productivity employees perform both...

In the financial economics literature debt contracts provide efficient solutions for addressing managerial moral hazard problems. We analyze a model with multiple projects where the manager obtains private information about their quality after the contract with investors is agreed. The...

This paper theoretically investigates how labor-market tightness affects market outcomes if firms use informal and self-enforcing agreements to motivate workers. We characterize profit-maximizing equilibria and derive the following results. First, an increase in the supply of homogenous workers...
