We analyze how quits responded to arbitrary differences in own and peer wages using an unusual feature of a pay raise at a large U.S. retailer. The firm's use of discrete pay steps created discontinuities in raises, where workers earning within 1 cent of each other received new wages that...

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...

We analyze how separations responded to arbitrary differences in own and peer wages at a large U.S. 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...

We study the impacts of a tracking program in a large urban school district that establishes separate "gifted/high achiever" (GHA) classrooms for fourth and fifth graders whenever there is at least one gifted student in a school-wide cohort. Since most schools have only a handful of gifted...

Low income and minority students are under-represented in gifted education programs. One explanation for this pattern is that the usual process for identifying gifted students, through parent and teacher referrals, systematically misses many potentially qualified disadvantaged students. We use...
