I am an economist. I may not have read Marx or Smith, but I did read "Potty Training in 3 Days" - properly historicizing my son's own methods of knowledge production.

Léonard Wantchekon's autobiography is spectacular. What a life. Tortured by the regime in Benin in his student days. Years in prison. Escaped to Nigeria, then Côte d'Ivoire, from there to Canada. PhD at Northwestern, first job at Yale. Founder of the African School of Economics. Highly recommended 👇

If you're at ASSA, consider going to the ASREC session on Sunday 8-10am, where my co-author @romainwacziarg.bsky.social will be presenting our paper "Malthusian Migrations"!
