It's been great fun talking to @angusbylsma.bsky.social about coins, trade, the 'end of antiquity', and even a little bit about methods and questions in economics and economic history.

Hopefully today’s SCOTUS decision on tariffs will mean the end of the preposterous EU-US trade ‘deal’. And hopefully the EU will be more respectful of the fundamental principles governing international trade, in particular MFN. Let the US exit the system if they want, let’s not help them destroy it.

Peter Temin, economic historian at MIT, has passed away. He worked both on problems of understanding the past (e.g. "Did Monetary Forces Cause the Great Depression?") and how how the past shapes the present (e.g. "The Vanishing Middle Class.") Terrific scholar and mentor, generous critic.

If this is accurate, then unless the EU eliminates all tariffs on industrial imports from all its WTO partners, it will be joining Trump in destroying the international trade rules that have applied since WW2. The difference being that while Trump hates the rule-based order the EU claims to value it

Today's trade deal between the US and the EU -- if as reported in the press, and if independent from other agreements -- is a massive mistake on the EU's side. Instead it should have called Trump's bluff. Trump would not have imposed 30% on EU imports for long.

On Europe as a destination for US-based scientists: it's a great place to live and work. Salaries aren't as high as US ones, but for seniors they're fine and we live well. (More could be done for juniors in some states.) We get European benefits. And the ERC offers great support for top researchers.

The end of history viewpoint so prevalent in contemporary thought is dealt another severe blow: venal corruption and systematic corruption are back. This like other 'I didn't think that could happen again' moments underscore the value of economic history and history more generally.
