Super excited to see this labour of love out in the Journal of Political Economy! 🤩 I find that getting neighbours to talk to each other about hiring a transgender worker can on its own drastically reduce discrimination in urban India www.journals.uchicago.edu/doi/10.1086/...

When I got tenure, I decided to use it start a new research agenda, studying US science in the 20th century, how it became dominant, what held it back, and what we can do better. Here's the first pub (with Scott Kim).

We could have had a very different rollout of LLMs than we actually did. It could have focused on building applications that made life easier for everyday use. Limited but useful. Instead, the buildout was focused on a radical and flawed proposition: that it could replace much of human labor.

The combination of earnings inequality and economic stagnation has led to the growing importance of wealth, and a decline in social mobility. Economic inequalities have also resulted directly in dangerous differences between regions and in political power across groups.

This is exactly what our research shows: when it becomes harder to tell apart expert-looking content from the real thing, the value of expertise goes up. And so does demand for it… giftarticle.ft.com/giftarticle/... AI hallucinations haunt users more than job losses

Brazil's Bolsonaro guilty of coup charges, court majority decides in landmark trial
Former Brazilian president Jair Bolsonaro was convicted by a Supreme Court majority on Thursday of plotting a coup to remain in power after losing the 2022 election, a powerful blow to the populist far-right movement he created.

I'd love to fund studies of interventions that reduce real-time pollution exposure, in the US, on outcomes related to violence and criminal behavior. (There is strong evidence that such exposure increases violence in real time; the next question is how much interventions can mitigate this effect.)
