The Fed spent down a lot of credibility when it looked through the temporary post-Covid inflation and managed to engineer a rare soft landing. But this probably means it has less of an ability to do so again now (less credibility). That means a more aggressive approach is probably optimal this time

CDU/CSU &SPD have just proposed a sea change in German fiscal policy: - defence spending above 1% of GDP exempt from debt brake - 10-year €500bn special fund for infrastructure - looser debt rules for states - further debt-brake reform in new Bundestag

This is a useful example of how economists’ mental model of climate change leads us astray. The idea is that optimal climate policy is a carbon tax of ~$200/ton, and IRA is equivalent to a carbon tax around $10/ton, so we need 20x stronger policy. That's wrong 🧵

🚨 Oprea (2024 AER) argued that prospect theory choice anomalies were not due to risk, but due to complexity-driven mistakes. But this new analysis convinces me that Oprea (2024) is substantially wrong. In my opinion, the paper should be retracted.

A new working paper with Daniel Banki, @urisohn.bsky.social and Robert Walatka, just submitted to SSRN. The paper is comment on Ryan Oprea's recent AER paper. The paper is processing, but you, my friends, get early entry. papers.ssrn.com/sol3/papers....

Title Authors Abstract (Decision under Risk are Decisions Under Complexity: Comment)

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.

John Joseph Wallis's 2006 paper "The Concept of Systematic Corruption in American History" is a ridiculously good paper. We usually think of corruption as rent seeking. But systematic corruption is rent creating to feed a political coalition. This is a huge barrier to growth.
