Screenshot of the articles title "Stratified Scars: social inequality in the labour market consequences of apprenticeship dropout" and the abstract: While the association between apprenticeship dropout and negative labour market consequences is well documented, the causal link and social stratification in this effect are less clear. Using georeferenced German administrative data and a conditional instrumental variable approach that exploits distance between place of residence and large firms, we find negative financial consequences but show that the dropout penalty is entirely concentrated among individuals from disadvantaged backgrounds. We further show that these stratified scars partly reflect unequal educational reenrolment rates and unequal employment outcomes among dropouts who do not reenrol. Our results highlight the potential of policies targeting higher graduation rates to reduce social inequality and suggest social advantage buffers the negative financial consequences of apprenticeship dropout, even in institutional settings with strong links between credentials and labour market outcomes.

How costly is apprenticeship dropout—and for whom?

Using an IV approach, our new @europeansocreview.bsky.social article finds strong income penalties, but only for students from disadvantaged backgrounds.

Most segregation research examines neighborhoods, schools, or workplaces separately. But do individuals' exposure align across domains and persist over the life course? We fill this gap using 27 years of 🇸🇪 data.

Results for CEM and neighborhood fixed effects regressions. We find robust and significant positive effects (blue coefficients) of childhood exposure to different ethnicities on the likelihood of interethnic marriage.

Left: georeferenced households in 1880. Right: Ethnic organic neighborhoods in Manhattan in 1880. Six ethnic groups are prevalent: first/second generation Americans, Asians, Germans, Irish and Others (residual category). We use these neighborhoods to account for segregation by applying organic neighborhood fixed effects.

“Potential” and the Gender Promotion Gap†
By Alan Benson, Danielle Li, and Kelly Shue*
We show that subjective assessments of employee “potential” contribute to gender gaps in promotion and pay. Using data on 29,809
management-track employees from a large retail chain, we find that
women receive substantially lower potential ratings despite receiving
higher performance ratings. Differences in potential ratings account
for approximately half of the gender promotion gap. Women’s lower
potential ratings do not reflect accurate forecasts of future performance: Women subsequently outperform male colleagues, both on
average and on the margin of promotion. We highlight two mechanisms driving the gender potential gap: strategic retention and stereotyping. (JEL J16, J31, J71, L81, M12, M51)
