Important thread. Is the econ profession about to get flooded with a bunch of good-looking papers of dubious or hard-to-ascertain quality? In macro, this already happened ~20 years ago with DYNARE. Over night it became very hard to publish macro-theory papers, and the field split apart. 1/N

Auschwitz was at the end of a process. We must remember that it did not start from gas chambers. This hatred gradually developed: from ideas, words, stereotypes & prejudice through legal exclusion, dehumanization & escalating violence... to systematic and industrial murder. Auschwitz took time.

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again. www.nature.com/immersive/d4...

Canada has agreed to allow 49k Chinese EVs into the Canadian market, with the most-favored-nation tariff rate of 6.1%. As Canada intends to double its energy grid capacity and move towards clean power, the prime minister also welcomed China to invest in his country in these areas.

It begins. Canadians will soon experience the vast superiority of Chinese EVs, and the US will lose its largest vehicle export market. The transition will happen much faster than people think.

The brilliant Kate Ho has passed away. She was an amazing economist and a genuinely kind human being. Her work shaped how we think about healthcare markets and her generosity touched everyone lucky enough to know her. The profession and the world are poorer without her.

Thrilled that my paper "The Cost of Curbing Externalities with Market Power: Alcohol Regulations and Tax Alternatives" with @cconlon.bsky.social was accepted by the Journal of Political Economy @jpolecon.bsky.social !

A new article in the WSJ on reverse acquihires. The main point it makes is that one group that loses out in a reverse acquihire are the employees who are left behind. This will make it more difficult for future startups to attract employees. www.wsj.com/tech/ai/ai-r...

I've been working on a new tool, Refine, to make scholars more productive. If you're interested in being among the very first to try the beta, please read on. Refine leverages the best current AI models to draw your attention to potential errors and clarity issues in research paper drafts. 1/

Just as dog whistles are high pitched so as to be only heard by dogs, some academic papers now have prompts for large language models invisibly inserted, in case the referee is a nLLM. marketdesigner.blogspot.com/2025/07/prom...

I have a new book! Digital Platform Regulation. Fun analysis of what society should do to get some competition out of of our favorite gatekeeper platform. Relevant to the DMA and US antitrust remedies. And free! Download here: som.yale.edu/centers/thur...

How do cross-border mergers & acquisitions affect innovation in the EU? In a new working paper, I discuss this question and the implications for foreign direct investment screening, merger policy and industrial policy: single-market-economy.ec.europa.eu/publications...

Trump may have given Canada & Mexico a brief reprieve, but talk of tariffs is rattling the economy and forcing a rethink of key industries & supply chains. Chief among them: the North American auto industry. This week on SHIFT KEY, we talk to Ford's former chief economist about Trump's tariffs. 🔌💡

NIH cuts billions of dollars in biomedical funding, effective immediately. The move halts a large slice of money for most universities and research institutions virtually overnight, imperiling vital research in everything from cancer to heart disease. www.washingtonpost.com/health/2025/...

I've gotten a flurry of requests to access my slides on "Models, Measurement, and Language in Economics" (presumably thanks to the great new year's reading list from @rohitlamba.bsky.social). The file is publicly available via my web page, but here is the link: www.dropbox.com/scl/fi/ntgkb...

While most of the cost in a traditional car is the engine, most of the cost in an electric car is somewhere else: the battery. And this is disastrous for Europe. Because a) we don't make many batteries and b) making batteries is a v v different skill to making engines

How is China's EV boom affecting gasoline demand and electricity demand? It has been hard to find precise data on this so here's a thread working out some numbers.

"Cars assembled in the US rely heavily on parts from Canada and Mexico. Just 68 of 141 models recorded as having been assembled in the US had engines and transmissions made in the country. For 42 models, parts from Mexico accounted for more than 15% of the total value." www.ft.com/content/3d21...

Norway recently implemented a weight tax on all vehicles (including electric!!) NOK 12.5 per kilogram over 500 kilograms. EV lobby groups and big car companies that have been aggressively bloating EV models for years are *very* pissed off about it.

A few weeks ago, I spoke on a panel about publishing at the CSWEP’s CeMENT workshop. I wanted to briefly share some of that advice here.

I am trying to be more active on here, and have not yet seen an IO or org econ starter pack, so here is an attempt at one: go.bsky.app/Rchu8QX Please shout out if I have forgotten someone, or when others join. #EconSky

New WP Governments use changes in tax rules to combat evasion. We exploit these changes to identify tax compliance. Example: Airbnb collection agreements. Full compliance is achieved by shifting the tax burden away from hosts to renters via the platform.1/2
