Fantastic job market paper from @vincent_rollet. Highlights key problem for upzoning — what can be built is shaped by the past. You need to demolish the small before you can build the large. This revises down the gains from upzoning, which accrue mainly to movers. 1/

Very excited to introduce @JanZemlicka (@uzh_df) and mine (@UNC_econ ) new paper on "Deep Learning in the Sequence Space". Our main idea: use truncated histories of aggregate shocks to summarize the endogenous aggregate state. Paper and details: arxiv.org/abs/2509.13623

Thank you, @FabioGhironi! Our recent paper with @FSMandel and @hewei_shen shows that high-skilled immigration restrictions can hurt US high-tech startups and have spill-over effects on firm entry and average firm productivity.

Fiscal policy is the most rate-sensitive part of the US economy. With high debt and a surge in short-term bills, short-rate moves influence deficits, debt service, and bondholder transfers. #FiscalPolicy #MonetaryPolicy #PublicDebt #InterestRates #FederalReserve #EconTwitter

It's common to hear "regression only identifies relative effects". To me, that's not a good way to think about it. What do "relative effects" even mean? Regression identifies *causal* effects but only under SUTVA. Without it, we model interference; GE models is one approach.

Very excited to release this paper. It extends all my previous work on productivity to heterogeneous agents: a measure of aggregate efficiency with interpretable units—resources left after compensating everyone— that is tractable, identified from observables (no interpersonal…

I have just posted my survey paper “Deep Learning for Solving Economic Models” on my webpage: sas.upenn.edu/~jesusfv/Deep_… In one or two weeks, it will also circulate as a working paper at the NBER and CEPR. Still, I wanted to let people know already, since I am quite happy with the…

This is the job market paper of the year, and the best paper on industrial policy I have ever seen. Industrial policy can affect outcomes either directly by changing an area’s fundamentals, or by coordinating simultaneous investment. How important is each? Let’s find out. 1/

Almost a decade ago I was the Harvard economist that said that bitcoin was more likely to be worth $100 than 100k. What did I miss? I was far too optimistic about the US coming to its senses about sensible cryptocurrency regulation; why would policymakers want to facilitate tax…
