The Appalachian region has experienced persistently higher poverty and lower earnings than the rest of the United States. We examine whether skill differentials or differences in the returns to those skills lie at the root of the Appalachian wage gap. Using census data, we decompose the Appalachian wage gap using both mean and full distribution methods. Our findings suggest that significant upgrading of skills within the region has prevented the gap from widening over the last 20 years. Additionally we find that urban areas within Appalachia have not experienced the rise in returns to skills as in non-Appalachian urban areas.

We use unique workplace and employee-level data to evaluate a major UK government pilot program to increase qualification-based, employer-provided training for low-qualified employees. We evaluate the program’s effect using a difference-in-differences approach. Using data on eligible employers and workers we find noevidence of a statistically significant effect on the take-up of training in the first 3 years of the program. Our results suggest that the program involved a high level of deadweight and that improving the additionality of the subsequent national program is crucial if it is to make a significant contribution toward government targets to increase qualification levels.

We estimate the causal effect of attending a state Faith school on primary education achievement in England using administrative student-level data and implementing various strategies to control for students’ selection into Faith schooling. Our regressions control for fixed effects in prior achievement and residential postcode to compare pupils who are close residential neighbors and have identical observable ability. We also use information on future school choices to control for preferences for Faith schooling. Results show that pupils progress faster in Faith primary schools, but all of this advantage is explained by sorting into Faith schools according to preexisting characteristics and preferences.

A positive relation between parents’ schooling and child’s schooling does not necessarily reflect a causal relation. This article uses a new approach to identify intergenerational schooling effects: a nonparametric bounds analysis. By relying on relatively weak and in part testable assumptions, this article obtains informative bounds on the average causal impact of parents’ schooling. The tightest bounds, using monotone instrumental variables, show that increasing mother’s or father’s schooling to a college degree has a positive effect on child’s schooling that is significantly different from zero but substantially lower than the ordinary least squares estimates.

In labor markets, the ratchet effect refers to a situation where workers subject to performance pay choose to restrict their output, because they rationally anticipate that firms will respond to higher output levels by raising output requirements or by cutting pay. We model this effect as a multiperiod principal-agent problem with hidden information and study its robustness to labor market competition both theoretically and experimentally. Consistent with our theoretical model, we observe substantial ratchet effects in the absence of competition, which are nearly eliminated when competition is introduced; this is true regardless of whether market conditions favor firms or workers.

We analyze the impact on a firm’s profits and optimal wage rates, and on the distribution of workers’ earnings, when workers compare their earnings with those of coworkers. We consider a low-productivity worker who receives lower wage earnings than a high-productivity worker. When the low-productivity worker derives (dis)utility not only from his own effort but also from comparing his earnings with those of the high-productivity worker, his response to the sensing of relative deprivation is to increase the optimal level of effort. Consequently, the firm’s profits are higher, its wage rates remain unchanged, and the distribution of earnings is compressed.

This article examines how the increase in the incarceration of black men and the sex ratio imbalance it induces shape the behavior of young black women. Combining data from the Bureau of Justice Statistics and the Current Population Survey to match male incarceration rates with individual observations over two decades, I show that black male incarceration lowers the odds of black nonmarital teenage fertility while increasing young black women’s school attainment and early employment. These results can account for the sharp bridging of the racial gap over the 1990s for a range of socioeconomic outcomes among females.
