Unemployed households' access to unsecured revolving credit more than tripled over the last three decades. This paper analyzes how both cyclical fluctuations and trend increases in credit access impact the business cycle. The main quantitative result is that credit expansions and contractions...

The effect of coworkers on the learning and the productivity of an individual is measured combining theory and data. The theory is a frictional equilibrium model of the labor market in which production and the accumulation of human capital of an individual are allowed to depend on the human...

We develop a tractable quantitative, general equilibrium, oligopsony model of the labor market that we use to measure the macroeconomic implications of labor market power. Strategic interaction complicates inference of parameters that are key to this exercise. To address this challenge, we...

How does consumer credit access impact job flows, earnings, and entrepreneurship? To answer this question, we build a new administrative dataset which links individual employment and entrepreneur tax records to TransUnion credit reports, and we exploit the discrete increase in consumer credit...

This paper documents the abnormally slow recovery in the labor market during the Great Recession, and analyzes how mortgage modification policies contributed to delayed recovery. By making modifications means-tested by reducing mortgage payments based on a borrower's current income, these...

We measure the distribution of welfare losses from non-competitive behavior in the U.S. credit card industry during the 1970s and 1980s. The early credit card industry was characterized by regional monopolies that excluded competition. Several landmark court cases led the industry to adopt...

This paper exploits matched data from the PSID on borrower mortgages with income and demographic data to quantify the relative importance of negative equity, versus lack of ability to pay, as affecting default between 2009 and 2013. These data allow us to construct household budgets sets that...

This paper documents that the time required to initiate and complete a home foreclosure rose from about 9 months on average prior to the Great Recession to an average of 15 months during the Great Recession and afterward. We refer to these changes as foreclosure delay. We also document that many...

We extend the baseline Susceptible-Exposed-Infectious-Recovered (SEIR) infectious disease epidemiology model to understand the role of testing and case-dependent quarantine. Our model nests the SEIR model. During a period of asymptomatic infection, testing can reveal infection that otherwise...

This paper studies the impact of state-level land-use restrictions on U.S. economic activity, focusing on how these restrictions have depressed macroeconomic activity since 2000. We use a variety of state-level data sources, together with a general equilibrium spatial model of the United States...
