Knowledge that Transforms

We investigate how high school gender composition affects students’ participation in STEM at college. Using Danish administrative data, we exploit idiosyncratic within-school variation in gender composition. We find that having a larger proportion of female peers reduces women’s probability of enrolling in and graduating from STEM programs. Men’s STEM participation increases with more female peers present. In the long run, women exposed to more female peers are less likely to work in STEM occupations, earn less, and have more children. Our findings show that the school peer environment has lasting effects on occupational sorting, the gender wage gap, and fertility.

Hurricanes Katrina and Rita devastated the US Gulf Coast in 2005. We use job-level data to compare the evolution of earnings for affected workers in four states with workers from matched control counties. We attribute short-term earnings losses to job separations and long-term gains to wage growth in the affected areas. Wages rose due to reduced labor supply and increased labor demand in the affected labor markets. Damage to a worker’s residence or workplace accentuated short-term earnings losses. Effects varied by prestorm industry, with larger gains for workers in sectors related to rebuilding.

Jurisdictions across the United States have adopted “ban the box” (BTB) policies preventing employers from asking about job applicants’ criminal records until late in the hiring process. Their goal is to improve employment outcomes for those with criminal records, with a secondary goal of reducing racial disparities in employment. However, removing criminal history information could increase statistical discrimination against demographic groups that include more ex-offenders. We use variation in the timing of BTB policies to test BTB’s effects on employment. We find that BTB policies decrease the probability of employment by 3.4 percentage points (5.1%) for young, low-skilled black men.

Low-skill workers are comparatively immobile. This paper estimates the role of housing prices and social transfers in accounting for this fact using a spatial equilibrium model. Reduced-form estimates using US census data show that positive local labor demand shocks increase population more than negative shocks reduce population, that this asymmetry is larger for low-skill workers, and that such an asymmetry is absent for average wages, housing values, and rental prices. Generalized method of moments estimates reveal that the comparative immobility of low-skill workers is due not to higher mobility costs but to a lower incidence of adverse labor demand shocks.

The list below specifies doctoral degrees conferred by U.S. and Canadian universities during academic year July 2019 to June 2020. Lists of degree recipients and subject classifications are provided by the university. Note: Dissertations without classifications may be found under “Y Miscellaneous Categories.”

Editor's Note Our policy is to annotate all English-language books on economics and related subjects that are sent to us. A very small number of foreign-language books are called to our attention and annotated by our consulting editors or others. Our staff does not monitor and order books published; therefore, if an annotation of a book does not appear six months after the publication date, please write to us or the publisher concerning the book.

The categories listed below are used to classify books, book reviews, journal articles, and dissertations indexed in JEL, JEL on CD, EconLit. New changes to the classification system appear as soon as possible on www.econlit.org . The JEL classification system may be used freely for scholarly purposes. We suggest the following format: “JEL: A10, B10, etc.”
