Who pays for tariffs? It’s a simple question that’s surprisingly tough to answer. We often see only a rough aggregate measure of prices at the border or the retail price, missing many steps in the chain.

We tackle this in a new paper w Aaron Flaaen, Ali Hortacsu, Felix Tintelnot and Daniel Xu

If you teach an undergrad international trade course and want some hands-on experience with real data & Stata or R, consider my “Gravity for Undergrads” Chapter. It may be useful in econometrics, undergrad seminars, and undergrad theses. Gravity Rules 💪

The US is playing countries off against each other. A coalition of the 🇪🇺,🇨🇦,🇲🇽,🇧🇷 & 🇰🇷 could put real pressure on Washington with a joint response. They would have strong leverage against tariffs. Read more in the new KPB 👉 ifw-kiel.de/publications...

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

Die geplante Finanzierung der #Gasspeicherumlage aus dem #KTF (TSP Background) entspricht einer Senkung des effektiven CO2-Preises auf Gas um 16 Euro. Größte Ironie: mit Einnahmen aus CO2-Preis bzw. dem Sondervermögen (das in den KTF fließen soll) wird nun fossile Energie subventioniert.
