We study a general equilibrium model in which entrepreneurs finance investment with optimal financial contracts. Because of enforceability problems, contracts are constrained efficient. We show that limited enforceability amplifies the impact of technological innovations on aggregate output....

This paper considers three questions: (1) what is the role of financial markets in development, (2) why do some economies have such poorly developed financial markets, and (3) can government policy be used to promote financial market development?

A large and increasing fraction of the value of executives' compensation is accounted for by security grants. It is often argued that the optimal compensation contracts characterized in the theoretical literature can be implemented by means of stock or option grants. However, in most cases the...

Recent studies have shown that the dynamics of firms (growth, job relocation and exit) are negatively associated with the firm's size. In this paper we analyze whether financial factors are important in generating this negative relation. We develop a model in which, at each point in time, firms...

Recent studies of the relationship between firm size and growth have overturned the conclusion of Gilbert's Law that firm size and growth are independent. In this paper we analyze whether financial factors are important in generating a negative relationship between firm size and growth. We...

This paper studies the political sustainability of the existing pay-as-you-go social security system in the face of recent demographic patterns. We analyze different approaches to privatizing the system and consider what it would require for them to be politically implementable. The analysis is...
