Ever wondered what housing value proxy for sales prices to use? Long story (in our @cesifo.org DP) short: Assessed values are good for quantification of QSMs. List prices better for hedonic valuation using panel identification. www.ifo.de/en/cesifo/pu... @hans-koster.bsky.social

How can traditional models fall short in measuring urban appeal? Our analysis reveals that neglecting mobility frictions causes an underestimation of the urban quality-of-life premium (QoL): increasing a region's population is associated with a significant increase in QoL. 190researchblog.subs...

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

What a fabulous 2025 @bsoeberlin.bsky.social www.bqse.de seminar season it has been! Thanks to all the co-organizers, our manager @immanuelfeld.bsky.social , all speakers, guests, and locals! You have been a fantastic spatial community! sites.google.com/view/bqse/bq...

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

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!

The 2025 season of the @bsoeberlin.bsky.social QSE course is running. Here is how it is going: sites.google.com/view/bqse/bq.... And here is my latest toy for the current cohort and anyone else. Maybe the simplest way of computing travel time matrices, designed for noobs! github.com/Ahlfeldt/TTM...

🏙️ The 14th European Meeting of the @urbaneconomics.bsky.social at @humboldtuni.bsky.social , marked a significant milestone as the largest in-person European meeting to date and over 200 paper presentations selected 📑👥👥 Discover more insights 👉 berlinschoolofeconomics.de/about-us/new... #UEA2025

Thanks to all presenters and discussants. So far, it seems to be going well (touch wood), thanks to our fantastic teams of true organizers! @bsoeberlin.bsky.social

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. Open-acces paper: www.sciencedirect.com/science/arti...

So cool, the first @bsoeberlin.bsky.social post is about spatial economics and why it matters!!! 😎

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-...

📯On March 28–29, 2025, Berlin will host the 14th European Meeting of the Urban Economics Association, a key event for urban & regional economics🌍 👥Thanks to local organizers @ahlfeldt.bsky.social & @jnimczik.bsky.social 👉 urbaneconomics.org/meetings/emu... #urbaneconomics @humboldtuni.bsky.social

📢 New article (in German) by our member @ahlfeldt.bsky.social Why investing in Baukultur (using high-quality materials, good design & sustainable planning) pays off ❕ Higher property values ❕ Less maintenance and energy costs ❕ Better urban environments 💡Can gain up to 10% higher market prices

Hier meine Zusammenfassung zum aktuellen Forschungsstand zu den ökonomischen Effekten guter #Architektur für #WerkBauenWohnen. Lange Rede, kurzer Sinn: Investitionen in Baukultur lohnen sich. Noch mehr wenn es eine Zerifizierung gäbe! @bseberlin.bsky.social www.pressreader.com/switzerland/...

Fabian and I explaining our new @cepr.org @cep-lse.bsky.social @bseberlin.bsky.social 'measurement paper'. Rosen-Roback with idiosyncratic tastes, local ties, trade gravity and local services! Packages that computes the measure (MATLAB, Stata, R, Python) available from: github.com/Ahlfeldt/ABR...

📢📢The Berlin School of Economics @BSE_Berlin will be recruiting PhD students in spatial economics 📢📢 (again). Still, time to apply before the 🧑‍🎄 break. See www.bqse.de for an overview of our activities in "spatial". Apply now & retweet! berlinschoolofeconomics.de/phd-programm...

By accounting for spatial frictions—the difficulty of moving—this study reveals larger quality-of-life differences between cities, uncovering new rankings and urban leaders. Great work co-authored by our member @ahlfeldt.bsky.social @humboldtuni.bsky.social 🌍📊 #urbaneconomics #qualityoflife 👇

What a great way to start my sabbatical in #Barcelona. Already loving it!

I did not handle it, but I am thrilled that this cool paper by @eviladecans & @MiquelAngelGL is out in @RegScUrbEc. It is not just access to jobs that matters for urban gradients. Amenities matter, too. And they will still matter if/when we all telecommute... doi.org/10.1016/j.re...

Delighted to welcome @joarlinghaus.bsky.social as a co-organizer for the 2025 season of the @bseberlin.bsky.social Quantitative Spatial Economics Research Seminar sites.google.com/view/bqse/co... May it be as fun and interesting as in 2024! @thiloalbers.bsky.social

Interested in the effects of planned #HSR in Poland? Here is another great project by a @HumboldtUni student from my QSE class assessing three proposed plans using the MRRH2018-toolkit (github.com/Ahlfeldt/MRR...). See their GitHub repository: github.com/jjkiljanski/...

What a great OSUS session today on the cool Agglomerations Shadow paper by @Rick__Hornbeck, Michaels, & Rauch. I had nerdy fun with the MRRH-toolkit (github.com/Ahlfeldt/MRR...) showing agglomeration shadows in the QSM (at 1h03m), too.😀Link to lecture: www.youtube.com/watch?v=TLpR...

Should Berlin extend the radial metro line U4 or build a circular U0? I love how our @HumboldtUni and @BSE_Berlin students are addressing such questions in their term papers using #QuantitativeSpatialModels. Marking feels rewarding!

Few non-economists will be surprised: When house prices go up, home buyers have to borrow more to sustain housing consumption. 🤔🤔🤔 Macroeconomic implications of this intuitive channel are substantial due to a feedback loop between prices and borrowing. bankofengland.co.uk/working-pape...
