Unemployment Insurance Taxes and Labor Demand: Quasi-Experimental Evidence from Administrative Data, Submitted [link here]

To finance unemployment insurance benefits, states raise payroll taxes on employers who engage in layoffs. Since tax rates increase in response to layoffs, taxes are highest for troubled firms after downturns, potentially hampering labor demand and employment during recoveries. I estimate the causal effect of these targeted tax hikes using a regression kind design and full-population administrative records from Florida, leveraging a kink in the tax schedule. The results show that hiring and employment are quite sensitive to unemployment insurance taxes, and I explore mechanisms behind the magnitude of the response. The findings highlight unanticipated costs of the financing regime which, once accounted for, reduce the optimal benefit calculation by a quarter.

Teacher Utility, Separating Eqiulibria, and Optimal Compensation: Evidence from a Discrete-Choice Experiment, in Preparation

Improving schools depends largely on attracting and retaining high-quality teachers, a means made straightforward by understanding teacher preferences for compensation structure and costly amenities. Since these preferences cannot be estimated from naturally occurring choice data, I deploy a discrete-choice experiment where teachers have reason to reveal their preferences. Estimated utility suggests that districts overpay in retirement and class size while underpaying in salary and merit rewards. If the best teachers have distinct preferences, compensation can be structured to differentially attract and retain them; high-quality teachers have preferences like other teachers for most attributes but have stronger preferences for schools offering merit rewards.


Potential Unemployment Insurance Duration and Labor Supply: Evidence from a Benefit Cut (with Alexandre Mas), Forthcoming at Journal of Political Economy[link here]

We examine how a 16-week cut in potential unemployment insurance (UI) duration in Missouri affected search behavior of UI recipients and the aggregate labor market. Using a regression discontinuity design (RDD), we estimate a marginal effect of maximum duration on UI and nonemployment spells of approximately 0.45 and 0.25 respectively. We use the RDD estimates to simulate the unemployment rate assuming no market-level externalities. The simulated response, which implies almost a one percentage point decline in the unemployment rate, closely approximates the estimated change in the unemployment rate following the benefit cut. This finding suggests that, even in a period of high unemployment, the labor market absorbed this influx of workers without crowding-out other jobseekers.

The Effect of Unemployment Benefits on the Duration of Unemployment Insurance Receipt: New Evidence from a Regression Kink Design in Missouri, 2003-2013 (with David Card, Pauline Leung, Alexandre Mas, and Zhuan Pei), American Economic Review: P&P, 2015. [link here]

We provide new evidence on the elasticity of unemployment insurance weekly benefit amount on unemployment insurance spells based on administrative data from the state of Missouri covering 2003-2013.  Identification comes from a regression kink design that exploits the quasi-experimental variation around the kink in the UI benefit schedule.  We find that unemployment durations are more responsive to benefit levels during the recession and its aftermath, with an elasticity of about 0.9 as compared to 0.35 pre-recession.
