How do job losers use default -- a phenomenon 6x more prevalent than bankruptcy -- as a type of "informal" unemployment insurance, and more importantly, what are the social costs and benefits of this behavior? To this end, I establish several new facts: (i) job loss is the main reason for...

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...

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 the publication of patents affect innovation? We answer this question by exploiting a large-scale natural experiment--the passage of the American Inventor's Protection Act of 1999 (AIPA)--that accelerated the public disclosure of most U.S. patents by two years. We obtain causal...

What are the welfare implications of labor market power? We provide an answer to this question in two steps: (1) we develop a tractable quantitative, general equilibrium, oligopsony model of the labor market, (2) we estimate key parameters using within-firm-state, across-market differences in...
