We study the welfare implications of market power in a model where banks choose between credit rationing and monitoring in order to alleviate an underlying moral-hazard problem. We show that the effect of banks’ market power on social welfare is the result of two countervailing effects. On the...

This paper develops a model of equilibrium in the market for loans. It focuses on the effects on equilibrium of (i) differences in the liability of the lender and the borrower for losses; and (ii) differences in the information available to the lender. We examine the different types of...

Motivated the European debt crisis, we construct a tractable theory of sovereign debt and structural reforms under limited commitment. The government of a sovereign country which has fallen into a recession of an uncertain duration issues one-period debt and can renege on its obligations by...

We characterize optimal incentive contracts in a moral hazard framework extended in two directions. First, after effort provision, the agent is free to leave and pursue some ex-post outside option. Second, the value of this outside option is increasing in effort, and hence endogenous. Optimal...

A 'folk theorem' originating, among others, in the work of Stiglitz maintains that competitive equilibria are always or 'generically' inefficient (unless contracts directly specify consumption levels as in Prescott and Townsend, thus bypassing trading in anonymous markets). This paper critically...

We examine a "Rotten Kid" model (Becker 1974) where a player with social preferences interacts with an egoistic player. We assume that social preferences are intention-based rather than outcome-based. In a very general multi-stage setting we show that any equilibrium must involve mutually unkind...

This research shows that moral hazard associated with extant social insurance arrangements causes underinvestment in human capital, because of government’s inability to commit to welfare policies. It then argues that education policies, such as education subsidies or direct public investment...

The promising prospect of a ‘New Economy’ in the US attracted substantial equity inflows in the late 1990s, helping to finance the country’s burgeoning current account deficit. After peaking in 2000, however, US stocks fell by some 8 trillion dollars in value. To assess the welfare effects...

This Paper studies the relationship between political wealth redistribution and the allocation of firm-ownership when production requires an unobservable input. The economy's wealth distribution affects the equilibrium interest rate and the allocation of entrepreneurial rents because wealth...

Performance indicators are increasingly used to regulate quality in health care and other areas of the public sector. We develop a model of contracting between a purchaser (principal) and a provider (agent) under the following scenarios: a) higher ability increases quality directly and...
