Using personnel data from a large U.S. retail firm, we examine whether the race or ethnicity of the hiring manager affects the racial composition of new hires. We exploit manager turnover to estimate models with store fixed effects and store-specific trends. First, we find that all nonblack managers-that is, whites, Hispanics, and Asians-hire more whites and fewer blacks than do black managers. This is especially true in the South. Second, in locations with large Hispanic populations, Hispanic managers hire more Hispanics and fewer whites than do white managers. We also examine possible explanations for these differential hiring patterns. (c) 2009 by The University of Chicago. All rights reserved.

We analyze how separations responded to arbitrary differences in own and peer wages at a large US retailer. Regression-discontinuity estimates imply large causal effects of own-wages on separations, and on quits in particular. However, this own-wage response could reflect comparisons either to market wages or to peer wages. Estimates using peer-wage discontinuities show large peer-wage effects and imply the own-wage separation response mostly reflects peer comparisons. The peer effect is driven by comparisons with higher-paid peers—suggesting concerns about fairness. Separations appear fairly insensitive when raises are similar across peers—suggesting search frictions and monopsony are relevant in this low-wage sector. (JEL D63, J31, J42, J62, L81)

We test for customer discrimination with data from more than 800 retail stores employing over 70,000 individuals matched to census data on the demographics of each store's community. While our tests detect some increase in sales when the workforce more closely resembles potential customers, the effects we find are modest in magnitude. Customer discrimination is neither strong nor pervasive. We find little payoff to matching employee demographics to those of potential customers except when the customers do not speak English.
