We study the role of foreign-born workers in the growth of employment in STEM occupations since 1980. Given the importance of employment in these fields for research and innovation, we consider their role in a model featuring endogenous non-routine-biased technical change. We use this model to...

Despite great focus on and public investment in STEM education, little causal evidence connects quantitative coursework to students' economic outcomes. I show that state changes in minimum high school math requirements substantially increase black students' completed math coursework and their...

Should the generosity of unemployment benefits and the progressivity of income taxes depend on the presence of business cycles? This paper proposes a tractable model where there is a role for social insurance against uninsurable shocks to income and unemployment, as well as inefficient business...

We study an intensive math instruction policy that assigned low-skilled 9th graders to an algebra course that doubled instructional time, altered peer composition and emphasized problem solving skills. A regression discontinuity design shows substantial positive impacts of double-dose algebra on...

As a new type of technique, simplicial methods have yielded extremely important contributions toward solutions of a system of nonlinear equations. Theoretical investigations and numerical tests have shown that the performance of simplicial methods depends critically on the triangulations...
