The recent world energy crisis raises serious questions about the extent to which the United States should increase domestic oil production and develop alternative sources of energy. We examine the energy developments in Brazil as an important experiment. Brazil has reduced its share of imported...

This study uses county-level variation in implementation of calorie labeling laws in the US to identify the effects of such laws on body mass. Using the 2003 to 2012 waves of the Behavioral Risk Factor Surveillance System, we find a statistically insignificant average treatment effect for women...

Prior to the racial integration of schools in the southern United States, predominantly African American schools were staffed almost exclusively by African American teachers as well, and teaching constituted an extraordinarily large share of professional employment among southern blacks. The...

The My Brother's Keeper (MBK) Challenge developed by President Obama supports communities that promote civic initiatives designed to improve the educational and economic opportunities specifically for young men of color.

There is, however, little empirical evidence to support the Troesken hypothesis. Using city-level data published by the U.S. Bureau of the...

We use 1940 Census data to study the intergenerational transmission of human capital for children born in the 1920s and educated during an era of expanding but unequally distributed public school resources. Looking at the gains in educational attainment between parents and children, we document...

This paper exploits the history of Reconstruction after the American Civil War to estimate the causal effect of politician race on public finance. I overcome the endogeneity between electoral preferences and black representation using the number of free blacks in the antebellum era (1860) as an...

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...
