Thrilled to have this paper with Hansen Shao, "The Dynamics of Internal Migration: A New Fact and its Implications" accepted. We hope it changes the way you think about internal migration and that it provides a useful tool for economists to model location choices.

AI is everywhere. AI-related products account for 23% of U.S. imports in 2025. This study from @tradewartracker is very interesting. https://t.co/7z5ca0rdiP

1/ At long last, we are ready to share a revision of my 2023 paper on Austrian capital theory and global value chains. I say “we”, because the current draft is joint work with the great @AdrianPKulesza (G4 at Harvard).

Check out Francesco Ruggieri's JMP! He studies fiscal spillovers across overlapping jurisdictions (school districts, cities, special districts sharing a tax base). Much less explored than spillovers between neighbors. Fantastic data work and super carefully implemented!

Thrilled to see our decade-long research agenda with Teresa Fort (@Tfpiasecki) and Felix Tintelnot (@FelixTintelnot) on firm-level approaches to global value chains featured in the latest NBER Reporter. What a ride!

What is the value of new and improved goods? The question is central for our theories of trade and economic growth, in which the value of new and better goods provides the motive for trade, and is the source of long-run growth. 1/6

Let's put a 25% tariff into context. Here's a (brief) US tariff history back to 1900.
