I am too young to get nostalgic (at least I pretend), but 10 years after the "Berlin Wall" paper and with 15 years newer data I realize two things: 1) The Berlin spatial structure did not change that much 2) how much more convenient it has gotten to collect land values 😀 @reddingecon.bsky.social

Last day of the @bsoeberlin.bsky.social course in Quantitative Spatial Economics. What a great cohort! If you spot any of these faces on the job market, don't hesitate! Thoroughly impressed by their coursework—the nerdy discussions during the lectures: priceless! 🫰 sites.google.com/view/bqse/bq... f

I agree!

Gabriel M Ahlfeldt @ahlfeldt.bsky.social · Jul 5

Yep, I agree and thought it would be nice to show. With a spatially random holdout sample, RF clearly wins as expected...

Gabriel M Ahlfeldt @ahlfeldt.bsky.social · Jul 4

OLS, unlike RF can extrapolate spatial trends! Already looking forward to teaching it!

Preparing my Applied Econometrics course @humboldtuni.bsky.social using
@gaborbekes.bsky.social
great textbook gabors-data-analysis.com. Added a nerdy exercise to the application of Random Forrest to predicting Airbnb prices. OLS beats Random Forrest when predicting outside a spatial window!

Does it take extra skills to work in a large city? 🌆

In this new paper, we analyse online job vacancy data and find that jobs in large cities require more skills and a more diverse skill set, indicating a higher job complexity.

Städterankings nach Lebensqualität sind lustig. Immer kommt was anderes raus. Nicht mit uns!😀 Lebensqualität (zumindest das, was Ökonom:innen darunter verstehen) lässt sich auch objektiv messen. Ist das Ranking plausibel? @makronom.bsky.social @bsoeberlin.bsky.social makronom.de/wie-wichtig-...

Wie wichtig Lebensqualität für Wohnortentscheidungen ist

Warum ziehen immer mehr Menschen in Städte – und bieten sie wirklich eine höhere Lebensqualität? Eine neue Studie zeigt, dass klassische Methoden die Attraktivität urbaner Räume oft unterschätzen.
