We have too little architectural quality—even though it pays. The reason is a coordination failure.

We revised our Skyscraper Revolution paper github.com/Ahlfeldt/DPs...
Added indirect inference to estimate the QoL effect of density by matching causal reduced-form estimates in the model => more realistic counterfactuals. Quick read @voxeu.org: cepr.org/voxeu/column... @bsoeberlin.bsky.social

☕Kaffee für alle oder schicke Cafés für coole Kieze? 🤎 Wir diskutieren live zur prime time in der @rbb24.de Abendschau @humboldtuni.bsky.social @bsoeberlin.bsky.social Interview: box.hu-berlin.de/f/3b351d1660... Ganzer Ganzer Beitrag: www.rbb-online.de/abendschau/v...
Why is there less beautiful architecture than we'd like? Our research shows that because neighbours get the benefits for free while builders pay extra, the market systematically undersupplies the architecture we prefer, making a construction subsidy the most efficient fix.
🏙️ Do big cities boost productivity more than we think?
A study shows the benefits of urban density are reflected not only in higher wages, but also in higher commercial rents. Ignoring rent effects may underestimate the true economic gains of large cities.

Our urban economics colleagues at @humboldtuni.bsky.social are amazingly productive.
(And therefore, according to their latest research 👇🏼 we can expect our office rents to rise.)

📺 On @rbb24.de, @ahlfeldt.bsky.social discussed the entry of low-price coffee chains.
☕ He argued market-wide price declines are unlikely, as cafés compete beyond price. Current pricing may not be sustainable, though part of productivity gains reaches consumers.
