We estimate racial/ethnic achievement gaps in several hundred metropolitan areas and several thousand school districts in the United States using the results of roughly 200 million standardized math and reading tests administered to public school students from 2009-2013. We show that achievement gaps vary substantially, ranging from nearly 0 in some places to larger than 1.2 standard deviations...

Student achievement has been identified as an important contributor to economic growth. This paper investigates the hypothesis that redistributive government activities have a negative effect on investment in human capital using data from international comparative student achievement tests in Mathematics and Science for over 70 countries during the period 1980 to 2003. In fixed effects models, ...

This paper measures the effects of decentralizing educational responsibility to communities and schools on student outcomes. Using the example of El Salvador’s Community-Managed Schools Program (or, EDUCO, from the Spanish acronym, Educacion con Participacion de la Comunidad), which was designed to expand rural education rapidly following a civil war, it compares student achievement on standard...
