This paper identifies a class of multiperiod agency problems in which the optimal contract is tractable (attainable in closed form). By modeling the noise before the action in each period, we force the contract to provide sufficient incentives state-by-state, rather than merely on average. This...

The theory of international trade has paid scant attention to market institutions. Neither neoclassical theory nor new trade models typically specify the process by which supply and demand meet. Yet in the real world, intermediaries play a central role in materializing the gains from exchange...

Contracts in a dynamic model must address a number of issues absent from static frameworks. Shocks to firm value may weaken the incentive effects of securities (e.g. cause options to fall out of the money), and the impact of some CEO actions may not be felt until far in the future. We derive the...

This paper develops a simple model of international trade with intermediation. We consider an economy with two islands and two types of agents, farmers and traders. Farmers can produce two goods, but in order to sell these goods in centralized (Walrasian) markets, they need to be matched with a...

This paper presents a market equilibrium model of CEO assignment, pay and incentives under risk aversion and heterogeneous moral hazard. Each of the three outcomes can be summarized by a single closed-form equation. In assignment models without moral hazard, allocation depends only on firm size...

We present a perfectly-competitive model of firm boundary decisions and study their interplay with product demand, technology, and welfare. Integration is pri- vately costly but is effective at coordinating production decisions; non-integration is less costly, but coordinates relatively poorly....

Economists and social scientists have long been interested in intergenerational mobility, and documenting the persistence between parents and children’s outcomes has been an active area of research. However, since Gary Solon’s 1999 Chapter in the Handbook of Labor Economics, the literature...

In order to credibly "sell" legitimate children to their spouse, women must forego more attractive mating opportunities. This paper derives the implications of this observation for the pattern of matching in marriage markets, the dynamics of human capital accumulation, and the evolution of the...

Household finance - the normative and positive study of how households use financial markets to achieve their objectives - has gained a lot of attention over the past decade and has become a field with its own identity, style and agenda. In this paper we review its evolution and most recent...

Microcredit seeks to promote business growth and improve well-being by expanding access to credit. We use a field experiment and follow-up survey to measure impacts of a credit expansion for microentrepreneurs in Manila. The effects are diffuse, heterogeneous, and surprising. Although there is...
