We’ve written a review on *New Industrial Policy* for the Oxford Research Encyclopedia.
It offers a unified framework for analyzing IP effects and survey evidence from both ex post event studies and ex ante model-based evaluations of IP.

We argue that climate clubs show promise:
- A climate club with coordinated penalties could curb 68% of excess emissions from free-riding
-Unilateral carbon tariffs? Not nearly as effective

We study how trade policy can reduce global emissions. Unilateral carbon border taxes have limited efficacy at cutting foreign emissions. By contrast, coordinated trade penalties under a climate club prove highly effective. buff.ly/NEE3Uy8

A new version of our trade war paper is out at the NBER this week.
Key update: factoring in tariffs on intermediate inputs nearly wipes out any terms-of-trade gains from reciprocal tariffs and greatly amplifies the cost of retaliation for the US economy.

🚨 We just released a paper examining the long-terms economic impacts of "Liberation Day" tariffs.
In summary: while these tariffs may help reduce the trade deficit, they will impose significant costs on the U.S. economy after retaliation by trade partners.

1/ 🚨 Can the US coerce smaller countries into submission using tariff penalties?
Recent events with Mexico & Canada suggest it is trying. But our latest research indicates these attempts will likely fail and isolate the US economy.

Check out Issue 2 of the VoxDevLit on International Trade! VoxDevLits adjust to new evidence, so there's lots new to uncover in this new issue. I've practically rewritten the chapter on externalities and spillovers from trade & FDI, and I'm excited to do it all over again as new evidence comes in!🎯🔥
Senior Editors David Atkin & Amit Khandelwal @yaleeconomics.bsky.social highlight key takeaways for trade policy from economic research.
This is an important time. For decades, trade barriers had been declining, but the direction of policy has become far less certain.
