Migrant rent penalties in the German housing market Abstract. We investigate whether migrants pay higher rents for comparable housing than natives with similar characteristics using nationally representative data from the 2018 German Microcensus. The d...

For a change, something we made ourselves: Together with my colleagues Tobias Roth, Andreas Horr, and @nataliebackes.bsky.social, we examined ethnic rent penalties. Do migrants pay higher rents for comparable housing than natives with similar characteristics? direct.mit.edu/euso/article...

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.

New preprint out with @wendering.bsky.social & Nan Zhang!

We show that childhood exposure to ethnic outgroups increases the prob. of #interethnic marriage decades later, using historical linked US census data (1880–1910) and next-door neighbor comparisons 🏠🌃

“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)

Sigtuna time!

I'm presenting work with @kostermann.bsky.social and @patzinaalex.bsky.social on the causal effect of apprenticeship dropout on earnings in Germany

Preprint is on @socarxiv.bsky.social: osf.io/preprints/so...

Text: In der sogenannten Postdoc-Phase, die bei vielen Menschen mit der Familiengründungsphase zusammenfällt, wird ein enormes Maß an Mobilität und Arbeitseinsatz bei gleichzeitig befristeten und unsicheren Beschäftigungsverhältnissen erwartet. Für Frauen, die immer noch den Großteil der Sorgearbeit leisten, ist das in dieser Lebensphase oft schlicht nicht zu leisten. Bild: Bettina Kohlrausch

Frauen promovieren fast genauso häufig wie Männer – doch zur Professur gelangen sie deutlich seltener. Für @bettikohlrausch.bsky.social, Direktorin des WSI, ist klar: Trotz Maßnahmen zur Förderung von Frauen behindert das Wissenschaftssystem die Aufstiegsmöglichkeiten von Frauen ganz offensichtlich.

@kostermann.bsky.social presented our joint work on how pioneer gentrifier follow artists and raise the gentrification probability in poor neighborhoods. Getting closer to understanding sorting patterns creates the possibility for prediction and intervention in spatial inequality.

Hello from Paris! 🇫🇷 Amazing @ninaglaeser.bsky.social gave with her JMP on skill sorting and #gentrifcation one of the first presentations at the urban and spatial PhD workshop at #CREST today. She investigates why high, medium and low qualified workers reside in different parts of a city 🌆🌃

Abstract for "The truly isolated: Spatial isolation of advantage in the United States" by Shannon Rieger, Angela Li, and Patrick Sharkey, published at Urban Studies

👉 Our new paper uses daily mobility data to show that spatial isolation is much more common today among those living in advantaged neighborhoods than the converse.

👩🏻‍💻 Lots of massive data wrangling and careful assumptions about mobility data needed - but check it out here! doi.org/10.1177/0042...

Attention is on NEETs today, but the problem is much worse.

NEETs include stay-at-home parents & jobseekers.

Strip those out to focus on people not working, not seeking work, not in education & not parenting: this group of economically & socially dislocated young adults has *doubled* in a decade.
