interesting working paper on effect of wealth taxation, in Norway 2021-2025. There is outmigration going on at the very top, but not much reduction in tax revenue. Also, no effect of startups and economic activity. www.nber.org/papers/w35854

Higher education is facing a serious crisis. Enrollment is starting to crater. The public has lost faith in the value of our institution. Business as usual is not an option.

The sheer figure of 20% blows my mind. Experts are probably well aware of that. That seems to be a little higher than the chances for russian soldiers to die within one year on the front. And we talk about scaring them away by depriving them of money or putting them in camps. And people think it's

Beta regression is underused in psychology. Back in the day, it was hard or impossible to do with software. Things have changed and you can now do it for free and with about as much ease as any other GLM. Whether you need description, prediction, or causal inference--beta regression can do it all.

Happiness is plummeting, especially among young people. When I see demoralizing data like this over and over again (e.g., test scores dropping, loneliness on the rise, etc), I just think we need to change course. Defending the status quo seems like such a bad option.

Very interesting project: Living Science uses an AI agent to reproduce key findings from seminal papers in economics, document what holds up and extend the analysis with newer data. It's like a follow-up paper with robustness checks and extensions. New paper every week.

Interesting new QJE paper shows inflation gets more attention when people are more exposed to it and when they have past inflation experiences. Those with inflation top of mind follow more inflation news, raise inflation expectations more; firms are more likely to raise prices.

Interesting QJE paper on fairness views of 65,000 individuals in 60 countries covering 85% of world population and 88% of global GDP. Meritocratic views more prominent in richer Western societies. Econ development and cultural factors account for ~80% of cross-country variation.

Europe is heading into a super election year in 2027. Those elections will take place against a precarious security backdrop: war in Ukraine and Iran, a retreating US & Europeans increasingly worried about their own security. So shouldn’t this benefit the political centre? Not so fast. 🧵
