After years in the making, I am happy to share a new guide for gravity estimations. Our recommendations are motivated by trade, but most of them apply broadly, e.g., to migration, FDI, etc. Mario, Serge Shikher, and I hope this is useful. Gravity rules 💪 ideas.repec.org/p/drx/wpaper/2…

EMERGENCY PODCAST EPISODE Trade Talks is back! Tariffs from the new U.S. President call for an emergency relaunch of the longstanding trade podcast. Aime Williams joins to explain what happened with Canada, Mexico, and China. tradetalkspodcast.com/podcast/201-tr…

Excited to see it in print and hope it will be helpful for authors, referees, and readers of papers with shift-share variables (not only IV)! Do not miss the conceptual discussion in "Shift-Share Basics", the summary of practical steps in Table 2, and Q&A in the online appendix

I see this too, and it should have steeper consequences. If people are not going to be held to pre-analysis plans, we should just cut the charade and skip the plans entirely. If we're going to have plans, egregious discrepancies should be treated as fraud.

Formula instruments are increasingly common: e.g. I notice most papers constructing climate shocks use them. Our new WP shows theoretically & practically how to build valid & powerful formula IVs. Big power gains in the simulated Medicaid eligibility setting. Comments welcome!

New tools for precisely estimating the effects of treatments defined by complex formulas, with an application to simulated instruments, from Kirill Borusyak and Peter Hull nber.org/papers/w33594

Has anyone heard back from the Barcelona Summer Forum? I'd like to know whether their silence means a rejection or delayed decisions.
