New paper w/ @hannohilbig.bsky.social: we examine how local exposure to the Great Recession affected politics over the long run. Counties where unemployment rose more in 2007–09 moved toward Democrats, not the populist right. The shift remained visible in 2022.

Are university still a left-wing thing in Europe? Unsure: HE is a hierarchical institution with egalitarian employees I find that universities increasingly inculcate selfish career concerns for status while leaving universalist concerns for global justice unchanged

Like this paper? Here's another that will be right up your alley. Here, the authors merge voter files & online resumes to create a dataset of 34.5M people. They show that Dems & Reps choose distinctive career paths and employers. This leads to a lot of partisan segregation at the workplace.

John Holbein@johnholbein1.bsky.social · last yr.

Wow! Three scholars at Columbia, Michigan, & Maryland just introduced a measure of the partisan leanings of employers in the U.S. The data is constructed by linking voter registrations to online worker profiles. VRscores capture the political affiliations of 21.8M workers across 2.6M employers.

About 214,000* Germans living abroad had registered to vote** in yesterday's election. Because this was a snap election with a compressed timeline, many voters didn't receive their absentee ballots in time.*** I'm one of them: mine arrived today. The day after the election.
