Over the past 40 years the fraction of mixed race black-white births has increased nearly nine-fold. There is little empirical evidence on how these children fare relative to their single-race counterparts. This paper describes basic facts about the plight of mixed race individuals during their...

We develop a Roy model of social interactions in which individuals sort into peer groups based on comparative advantage. Two key results emerge: First, when comparative advantage is the guiding principle of peer group organization, the effect of moving a student into an environment with...

The extent to which discrimination can explain racial wage gaps is one of the most divisive issues in the social sciences. Using a newly available data set, this paper develops a simple empirical test that, under plausible (but not innocuous) conditions, provides a lower bound on the extent of...

The extent to which discrimination can explain racial wage gaps is one of the most divisive subjects in the social sciences. Using a newly available dataset, this paper develops a simple empirical test which, under plausible conditions, provides a lower bound on the extent of discrimination in...

There is growing concern that improving the academic skills of disadvantaged youth is too difficult and costly, so policymakers should instead focus either on vocationally oriented instruction for teens or else on early childhood education. Yet this conclusion may be premature given that so few...

Domestic attempts to use financial incentives for teachers to increase student achievement have been ineffective. In this paper, we demonstrate that exploiting the power of loss aversion--teachers are paid in advance and asked to give back the money if their students do not improve...

This paper describes a field experiment in Oklahoma City Public Schools in which students were provided with free cellular phones and daily information about the link between human capital and future outcomes via text message. Students' reported beliefs about the relationship between education...

In the 1960's, Blacks and Whites chose relatively similar first names for their children. Over a short period of time in the early 1970's, that pattern changed dramatically with most Blacks (particularly those living in racially isolated neighborhoods) adopting increasingly distinctive names,...

This paper describes basic facts regarding the black-white test score gap over the first four years of school. Black children enter school substantially behind their white counterparts in reading and math, but including a small number of covariates erases the gap. Over the first four years of...

In previous research, a substantial gap in test scores between White and Black students persists, even after controlling for a wide range of observable characteristics. Using a newly available data set (Early Childhood Longitudinal Study), we demonstrate that in stark contrast to earlier...
