💥New Working Paper!💥 Women in Peru🇵🇪 spend 3 to 4 hours per day more than men in unpaid domestic and care work, regardless of their labour force participation. With colleagues @mcgill.ca and GRADE, we wanted to see whether beliefs about gender norms could help explain this pattern.

Many interventions “work” in small trials but fail at scale

Also, EdTech often promises much, but delivers little

Our work now published showing how better AI can improve both accuracy and diversity in hiring relative to supervised learning tools and status-quo human hiring.
Li, @lindseyraymond.bsky.social & @peterbergman.bsky.social show that incorporating exploration into an interview screening algorithm improves demographic diversity & hiring efficiency, while traditional supervised learning-only tools improve hiring rates at the expense of minority applicants.

The tragic landslide in Blatten gives me the excuse to tell you the story of how we found out Ice Ages existed. It's a cool story and the most important bit is rather similar to what's happening now.

This is a pretty remarkable set of results. I got fixated on adults in this, since it seems like a big change!

One fact that I discovered by digging into the original reports is that this masks some pretty interesting heterogeneity:

This figure shows the key result on profits: over 2 years men and women have similar average and quantile treatment effects, with profits growing $61-65/month (for a $750 training). After 7 years, treatment effects on profits for men are $148/month, vs $39/month for women. 2/3

🚨 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.

These new analyses include, for the first time, administrative data on income and employment and results for marriage/ divorce and benefits, among other outcomes.

The LA wildfires have given landlords an opportunity to raise rents. California has anti-price-gouging regulation that might prevent that.

If you want to step beyond Econ 101, here’s a recent Econometrica paper that shows how price caps can raise welfare.
