In every period, an aggressive country seeks concessions from a non-aggressive country with private information about their cost. The aggressive country can force concessions via war, and both countries suffer from limited commitment. We characterize the efficient sequential equilibria. We show that war is necessary to sustain peace and that temporary wars can emerge because of the coarseness o...

Producer Protection Legislation and Termination Damages in the Presence of Contracting Frictions This study models producer protection legislation that would grant growers the right to claim damages (PPLD) if their contracts are prematurely terminated. In the absence of contracting frictions that prevent contractors from redesigning contracts to accommodate exogenous policy changes, PPLD would ...

This paper extends the concept of a quota contract to account for discounting and for the possibility of infinitely many periods: a discounted quota fixes the number of expected discounted plays on each action. I first present a repeated principal-agent contracting environment in which menus of discounted quota contracts are optimal. I then recursively characterize the dynamics of discounted qu...

This paper investigates the optimality of sharp incentives in contracts where output prices are set at the time of contracting but are random in nature. It shows that when prices are specified with error, schemes involving sharp incentives might result in substantial deviations from first-best output levels. The randomness of prices creates arbitrage opportunities that are exploited by agents p...

I study asset prices in a two-agent production economy in which the worker has private information about her labor productivity. The shareholder offers an incentive compatible long-term labor contract, which partially insures the worker against labor income risk. I compare the model’s performance to settings with a competitive labor market, and with static labor contracts. My model successfully...

Contracts that reference rivals have long been a focus of antitrust law and the subject of intense scholarly debate. This paper compares two such contracts, exclusive-dealing contracts and market-share contracts, in a model of naked exclusion. We discuss the different mechanisms through which each works and identify the fundamental tradeoff that arises: marketshare contracts are better at maxim...

We consider a repeated moral hazard problem, where both the principal and the wealth-constrained agent are risk-neutral. In each of two periods, the principal can make an investment and the agent can exert unobservable effort, leading to success or failure. Incentives in the second period act as carrot and stick for the first period, so that effort is higher after a success than after a failure...

Can Contracts Signal Social Norms? Experimental Evidence We investigate whether incentive schemes signal social norms and thus affect behavior beyond their direct economic consequences. A principal-agent experiment is studied in which prior to contract choice principals are informed about past actions of other agents and thus have more information about “norms of behavior”. Compared to a settin...

Growing economic and psychological evidence documents effects of target setting on levels of effort and risk-taking, even in the absence of a monetary reward for attaining the target. I explore a principal-agent environment in which the principal sets the agent a performance target, and the agent’s intrinsic motivation to work is influenced by their performance relative to the target. When the ...

Thinking about contingencies, designing covenants and seeing through their implications is costly. Parties to a contract accordingly use heuristics and leave it incomplete. The paper develops a model of limited cognition and examines its consequences for contractual design. JEL numbers: D23, D82, D86, L22.
