An economy in which deposit-taking banks of a Diamond/Dybvig style and an asset market coexist is modelled. Firstly, within this framework we characterize distinct financial systems depending on the fraction of households with direct investment opportunities that are less efficient than those...

This paper studies relationship lending in a framework where the cost of switching banks measures the degree of banking competition. The relationship lender’s (insider bank’s) informational advantage creates a lock-in effect, which is at its height when the switching cost is infinitesimal....

This paper analyzes sequential games of double-sided Bertrand competition in the deposit and credit markets, when banks are free to reject customers and cannot distinguish among borrowers. The timing of competition is crucial when customers apply once. Interest rates are pushed upwards when the...

As a reaction to the general suspicion that margin loans had been a key element of the stock market boom and crash of the late 1920s, the Federal Reserve Bank was empowered to regulate margin lending with the Securities and Exchange Act. The efficacy of the Federal Reserve's margin policy has...

We wish to study optimal dynamic nonlinear income taxes. Do real world taxes share some of their features? What policy prescriptions can be made? We study a two period model, where the consumers and government each have separate budget constraints in the two periods, so income cannot be...

We investigate the interactions between optimal regulation and external credit constraints. When part of a regulated ¯rm is owned by foreign investors, a credit-constrained country who wants to send pro¯ts abroad has to generate enough surplus in the trade account in order to compensate...

This paper deals with the optimality of teacher incentive contracts in the presence of costly or limited government resources. It considers educational production under asymmetric information as a function of teacher effort and class size. In the presence of costly government resources and...

When potential shareholders cannot observe the business conditions of the firms, the latter desiring to acquire capital by an IPO and operating under less favourable business conditions have a strong incentive to appear more successful.

Suppose an altruistic person, A, is willing to transfer resources to a second person, B, if B comes upon hard times. If B anticipates that A will act in this manner, B will save too little from both agents' point of view. This is the Samaritan's dilemma. The logic of the dilemma has been...

This paper discusses a model where consumers simultaneously differ according to one unobservable (preference for quality) and one observable characteristic (location). In these circumstances nonlinear prices arise in equilibrium. The main question addressed in this work is whether firms should...
