We find that banks charge more for overdraft credit when depositors have access to a potential substitute: deferred deposit ("payday") credit. We attribute this rise in prices partly to adverse selection created by banks' practice of charging a flat fee regardless of the overdraft...

In this paper, we address the question whether increasing households' financial market access improves welfare in a financial system in which there is intense competition among banks for private households' funds. Following earlier work by Diamond and by Fecht, we use a model in which the degree...

Following the investment-cash flow literature, we test whether bank lending is constrained by the availability of insured deposits--a necessary condition for the existence of bank lending channel of monetary policy. We treat insured deposits as a type of "internal fund," similar to cash flows....

We study the role of commitment in a version of the Diamond-Dybvig model with no aggregate uncertainty. As is well known, the banking authority can eliminate the possibility of a bank run by committing to suspend payments to depositors if a run were to start. We show, however, that in an...

In the literature, bank runs take the form of withdrawals of real demand deposits that deplete a fixed reserve of goods in the banking system. This framework describes the type of bank run that has occurred historically in the United States and more recently in developing countries. However, in...

This paper explores sources of deposit dollarization unrelated to standard moral hazard arguments. We develop a model in which banks choose the optimal currency composition of their liabilities. We argue that the equal treatment of peso and dollar claims in the event of bank default can induce...

Remarks at the Global Economic Policy Forum, New York City.

This paper shows that bank performance improves significantly after restrictions on bank expansion are lifted. We find that profits increase and loan quality improves after states permit statewide branching, and--to a lesser extent--after states allow interstate banking. The improvements...

This paper shows that bank competition has an intrinsically ambiguous effect on capital accumulation and economic growth. We further demonstrate that banking market structure can be responsible for the emergence of development traps in economies that would otherwise be characterized by unique...
