How far can you get in 60 minutes? European cities offer vastly larger areas reachable by public transit than US cities of comparable population size. Source: lconwell.github.io/lucasconwell...

Example for the two staged unsupervised machine learning algorithm using point data as input. Backlayer maps depict Hamburg. The map shows neighborhoods in different sizes and forms, sometimes following administrative borders (black lines) sometimes not. Three differently colored neighborhood types are displayed, each representing a different social group of residents.

Looking for a measure of #neighborhoods, micro or macro #segregation?

I've got something for you!

My newly published paper in Sociological Methods & Research presents a machine-learning-based algorithm to delineate neighborhoods with grid-cell or point data:

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 πŸ‡ΈπŸ‡ͺ 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.

β€œPotential” and the Gender Promotion Gap†
By Alan Benson, Danielle Li, and Kelly Shue*
We show that subjective assessments of employee β€œpotential” 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)
