Abstract
Between 1910 and 1940, U.S. high school graduation rates rose five-fold, driving twentieth-century economic growth. I explore how the Great Depression’s surge in youth unemployment influenced this trend, emphasizing gender and socioeconomic disparities. Using linked census data and newly digitized city-level unemployment rates, I find that youth unemployment significantly increased high school and post-secondary completion among higher-income boys, while effects on girls and lower-income youths were negligible. These results underscore the role of household resources in leveraging educational opportunities, as financial constraints limited disadvantaged groups from benefiting from reduced opportunity costs. *
