We develop a model of banking industry dynamics to study the quantitative impact of capital requirements on bank risk taking, commercial bank failure, and market structure. We propose a market structure where big, dominant banks interact with small, competitive fringe banks. Banks accumulate...

First Draft: November 1, 2011 We propose a theory of endogenous firm-level volatility over the business cycle based on endogenous market exposure. Firms that reach a larger number of markets diversify market-specific demand risk at a cost. The model is driven only by total factor productivity...

Accepted for publication, Journal of Economic Dynamics and Control The aim of this paper is to quantify the role of formal-sector institutions in shaping the demand for human capital and the level of informality. We propose a firm dynamics model where firms face capital market imperfections and...

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...
