The authors present a theory of unsecured consumer debt that does not rely on utility costs of default or on enforcement mechanisms that arise in repeated-interaction settings. The theory is based on private information about a person's type and on a person's incentive to signal his type to...

The authors' aim in this paper is to obtain a measure of the potential benefit of reducing the likelihood of economic crises. The authors define an economic crisis as a Depression-style collapse of economic activity. Based on the observed frequency of Depression-like events, the authors estimate...

In this paper the authors estimate the potential benefit of policies that eliminate a small likelihood of economic crises. They define an economic crisis as a Depression-style collapse of economic activity. For the U.S., based on the observed frequency of Depression-like events, the authors...

The authors compute the potential economic benefits that would accrue to a typical pre-WWII era U.S. worker from the post-WWII macroeconomic policy regime. The authors assume that workers face undiversifiable income risk but can self-insure by saving in nominal assets. The worker's average...

The potential benefit of policies that eliminate a small likelihood of economic crises is calculated. An economic crisis is defined as an increase in unemployment of the magnitude observed during the Great Depression. For the U.S., the maximum-likelihood estimate of entering a depression is...

What caused the worldwide collapse in output from 1929 to 1933? Why was the recovery from the trough of 1933 so protracted for the U.S.? How costly was the decline in terms of welfare? Was the decline preventable? These are some of the questions that have motivated economists to study the Great...

The authors develop a variant of Townsend's turnpike model where the trading friction is related to a commitment problem rather than spatial separation alone. Specifically, expenditure on financial services is necessary to ensure commitment. When commitment is costless, the equilibrium...

In this paper, the authors describe and compare two approaches to analyzing transactions costs in a general equilibrium setting. In the first approach, which the authors label the transactions costs approach, the commodity space is the same as that used in models without transactions costs. In...
