Our paper is officially out 🎉 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.

I have several papers that explore tariff wars using economic models. Here’s what they tell us about likely outcomes (🧵) TLDR: All countries ultimately lose. While the overall impact isn’t catastrophic for larger economies like the US, it’ll be devastating for small countries.

new Trump head of the Council of Economic Advisors btw
“At the end of the day, government has to raise revenue via taxation.  Higher tax rates are much more dangerous than lower tax rates.

Taking effective tariff rates from 2% to 20% seems way better than taking maringal income tax rates from 30% even higher.”
