Disincentive Effects of Unemployment Insurance Benefits
Unemployment insurance (UI) acts both as a disincentive for labor supply and as a demand stimulus which may explain why empirical studies often find limited effects of UI on employment. This paper provides independent estimates of the disincentive effects arising from the largest expansion of UI in U.S. history, the pandemic unemployment benefits. Using high-frequency data on small restaurants and retailers from Homebase, we control for local demand effects by comparing neighboring businesses that largely share the positive impact of UI stimulus. We find that employment in low-wage businesses ...

Tariffs and Goods-Market Search Frictions
We study tariffs in a general equilibrium dynamic model with search frictions between heterogeneous exporting producers and importing retailers. We show the model has a unique equilibrium and analytically characterize home unilateral import tariffs that maximize welfare given a passive foreign country. Search frictions add two terms to the standard optimal tariff expression: One lowers tariffs when contact rates are low; another when private export costs exceed social opportunity costs. Search frictions also introduce new incentives to subsidize imports due to market thickness effects. We ...

Asset Prices and Unemployment Fluctuations
Recent critiques have demonstrated that existing attempts to account for the unemployment volatility puzzle of search models are inconsistent with the procylicality of the opportunity cost of employment, the cyclicality of wages, and the volatility of risk-free rates. We propose a model that is immune to these critiques and solves this puzzle by allowing for preferences that generate time-varying risk over the cycle, and so account for observed asset pricing fluctuations, and for human capital accumulation on the job, consistent with existing estimates of returns to labor market experience. ...

Unemployment Insurance during a Pandemic
The CARES Act implemented in response to the COVID-19 crisis dramatically increased the generosity of unemployment insurance (UI) benefits, triggering concerns about substantial effects on unemployment. This paper combines a labor market search-matching model with the SIR-type infection dynamics to study the effects of the CARES Act UI on both unemployment and infection. More generous UI policies create work disincentives and lead to higher unemployment but also reduce infection and save lives. Economic shutdown policies further amplify these effects of UI policies. Quantitatively, the CARES ...
