How Tariffs Affect Trade Deficits... ... a new paper with amazing trade economist Arnaud Costinot. Many politicians and the general public expect tariffs to reduce imports lower imports and thus work to close a trade deficit. Economists typically say "not so fast"... 🧵1/n

New paper on recent US tariffs with Matt Rognlie and Adrien Auclert Our focus: effects of temporary increases in tariffs (“tariff shocks") Three Qs: 1 Will tariffs lead to a recession? 2 Will they reduce the trade deficit? 3 Why are they not appreciating USD? (as in std theory) 🧵

Tariffs raise the price of investment goods relative to labor and depress the long-run capital stock, reducing long-run real consumption and wages, from @Dbaqaee and @hannesmalmberg1 nber.org/papers/w33702

🚨 New paper out! 🚨 Thiemo Fetzer 🇪🇺🇺🇦 - same handle elsewhere and I ask a simple question with big stakes: Do LLMs deliver reliable health advice around the globe? We benchmark 6 leading LLMs, ask advice in 21 languages & 9K real-world claims from. Short thread for results, data & code included. 1/6

“Among articles stating that data was available upon request, only 17% shared data upon request.”

I’ve open‑sourced all content from my talk Retrieving  &  Generating Data with LLMs in Python on my Github, along with slides. 🔓 10 Jupyter notebooks that show how to turn messy text into clean, structured data, all with GPT‑4o‑mini & the OpenAI API.

Across 300,000 papers published in top 100 economics journals, more than 90% of claims use language that is causal while less than 10% are actually using causal inference methods.

New paper & surprising result. LLMs transmit traits to other models via hidden signals in data. Datasets consisting only of 3-digit numbers can transmit a love for owls, or evil tendencies. 🧵

100% this. Most introductory Economics courses are unnecessarily mathphobic and serve as confusion amplifiers. Starting with e.g. a basic introduction to decision theory (which can be taught with secondary school Mathematics in a few weeks) would lead to a better equilibrium.
