I have loved math since I was a child, but it was not until I started teaching that I realized how challenging—and rewarding—it can be. I'm glad that some students have found it helpful along the way.

🚨New @nber.org WP🚨 We use data on 42,000 households in #India to study how the agricultural sector copes w/ labour loss. As #farmers move to cities for higher wages, their left-behind families *don't* substitute with increased capital -- they downsize their farms. (1/2)

@luongthuha presents a fascinating pattern that the Juntos cash transfer program in Peru is associated with shifts in gender attitudes toward traditional gender norms, seemingly driven by maternal time allocation

Hundreds of books have been written about India's resilient caste system. But if you read on Mauritius, Malaysia or the UK, caste weakens very rapidly among the diaspora, perhaps within two generations. Migration's transformative power is hugely under-appreciated.

Misattribution (when someone claims you said something that you’ve never said)–it’s kind of like plagiarism in reverse. statmodeling.stat.columbia.edu/2025/05/07/m...
