Much of my work is in two areas: The economics of education, and labor markets. In education, I have studied the identification of teacher quality, school choice, affirmative action, student loans, and college admissions. My labor markets research includes studies of unemployment insurance and of the labor market effects of the Earned Income Tax Credit.
I have also worked on local public finance and urban economics, with studies on residential segregation and the housing market valuation of school quality and of school facilities. Finally, I have worked on tax and transfer policy.
I direct the Institute for Research on Labor and Employment and the California Policy Lab, which pairs experts from the University with policymakers to solve public problems via research using administrative data.
