This article uses data from Major League Baseball's integration to identify the sources and magnitude of labor market discrimination. Returns to hiring black workers in this industry were high, and the industry's labor supply was uniquely suited for rapid integration, yet integration evolved slowly. Many explanations for this sluggishness are considered, including both taste-based and statistical discrimination. Ultimately, only owner and collective coworker discrimination can explain baseball's slow pace of integration. The estimated levels of discrimination are high, showing the median team sacrificed profits of nearly $2.2 million in 1950 dollars (over $19 million 2010 dollars) by delaying integration.
