What makes diversity unifying in some settings but divisive in others? We examine how the mixing of ethnic groups in German schools affects intergroup cooperation and trust. We leverage the quasi-random assignment of students to classrooms within schools to obtain variation in the type of...

Mounting evidence supporting the advantages of a diverse teacher workforce prompts policymakers to scrutinize existing recruitment pathways. Following four cohorts of Maryland public high-school students over 12 years reveals several insights. Early barriers require timely interventions, aiding...

We explore how umpires' racial/ethnic preferences are expressed in their evaluation of Major League Baseball pitchers. Controlling for umpire, pitcher, batter and catcher fixed effects and many other factors, strikes are more likely to be called if the umpire and pitcher match race/ethnicity....

Using CPS data from 1979-2009 we examine how cyclical downturns and industry-specific demand shocks affect wage differentials between white non-Hispanic males and women, Hispanics and African-Americans. Women's and Hispanics' relative earnings are harmed by negative shocks, while the earnings...

The wage gap between African-Americans and white Americans is substantial in the US and has slightly narrowed over the past 30 years. Today, blacks have almost achieved the same educational level as whites. There is reason to believe that discrimination driven by prejudice plays a part in...

Labor force transitions are empirically examined using CPS data matched across months from 1996-2012 for Hispanics, African-Americans and whites. Transition probabilities are contrasted prior to the Great Recession and afterwards. Estimates indicate that minorities are more likely to be fired as...

We investigate the relative significance of differences in cognitive skills and discrimination in explaining racial/ethnic wage gaps. We show that cognitive test scores taken prior to entering the labor market are influenced by schooling. Adjusting the scores for racial/ethnic differences in...

Using nine years of personnel records from a regional grocery store chain in the United States, this study examines the effect of manager ethnicity on the ethnic composition of employment at the firm's 73 stores. We estimate separate models with store fixed effects for several departments and...
