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

In this article, we analyze the 1920s Ku Klux Klan, those who joined it, and its social and political impact by combining a wide range of archival data sources with data from the 1920 and 1930 U.S censuses. We find that individuals who joined the Klan in some cities were more educated and more...

This paper formalizes a widely discussed peer effect titled "acting White." "Acting White" is modeled as a two-audience signaling quandary: signals that induce high wages can be signals that induce peer group rejection. Without peer effects, equilibria involve all ability types choosing...

This article describes a series of school-based field experiments in over 200 urban schools across three cities designed to better understand the impact of financial incentives on student achievement. In Dallas, students were paid to read books. In New York, students were rewarded for...

We use a unique data set detailing the financial activities of a drug-selling street gang to analyze gang economics. On average, earnings in the gang are somewhat above the legitimate labor market alternative. The enormous risks of drug selling, however, more than offset this small wage premium....

We offer evidence that legalized abortion has contributed significantly to recent crime reductions. Crime began to fall roughly eighteen years after abortion legalization. The five states that allowed abortion in 1970 experienced declines earlier than the rest of the nation, which legalized in...

We develop an algorithm for detecting teacher cheating that combines information on unexpected test score fluctuations and suspicious patterns of answers for students in a classroom. Using data from the Chicago public schools, we estimate that serious cases of teacher or administrator cheating...

Lojack is a hidden radio-transmitter device used for retrieving stolen vehicles. Because there is no external indication that Lojack has been installed, it does not directly affect the likelihood that a protected car will be stolen. There may, however, be positive externalities due to general...

We are grateful to Foote and Goetz for noting that the final table of Donohue and Levitt (Quarterly Journal of Economics, 116 (2001), 379-420) inadvertently omitted state-year interactions. Correcting our mistake does not alter the sign or statistical significance of our estimates, although it...

Empirical studies have provided evidence that discrimination exists in various markets, but they rarely allow the analyst to draw conclusions concerning the nature of discrimination. By combining data from bilateral negotiations in the sportscard market with complementary field experiments, this...
