Migrants have been paying 7 to 10 times the actual processing costs of visas for years, and many have been forced into destitution by extortionate fees. Now this government has increased them again. Migrants are not a magic money tree for politicians to keep exploiting.

The policy of enforcing political beliefs upon all foreign visitors is radically anti-American.

It will sever us from international research networks and hobble our capacity to innovate—bedrock of American prosperity.

Americans reject authoritarian rule.

De l'avantage d'être de noble lignage pour intégrer une (très) grande école en France (1891-1995)

Encore un travail incroyable de @stephanebenveniste.com !

stephanebenveniste.com/wp-content/u...

Abstract:
This paper investigates the enduring overrepresentation of aristocratic families in
elite higher education. It analyses 269,917 graduates from ten leading French
grandes écoles between 1911 and 2015, using surname-based indicators of
nobility and a linkage to birth records. Despite a decline over time, descendants
of aristocrats remain nine times more likely to gain admission than the rest of the
population, even two centuries after the French Revolution. While historically
most concentrated at Sciences Po Paris, their presence has converged across
institutions, though business schools now exhibit the highest overrepresentation.
The analysis also reveals a gender gap, with noble men benefiting more from this
educational advantage. These findings highlight the persistence of historical
hierarchies beyond the end of legal privileges, as noble families convert symbolic
capital into academic credentials, ensuring continued access to elite status

My new paper with @guillaumeblanc.bsky.social is out as an NBER Working Paper. Demographic pressures have had lasting effects on the spread of diasporas. Malthusian migrations contributed to sustained improvements in living standards in Europe in the 19th century. www.nber.org/papers/w33542

I read this paper this morning on NBER working papers series and it blew my mind. Very impressive work.

Going to give this website a try - with a new profile picture! Definitely feels like an econ bubble, but I guess that’s the point.

Expect a thread on my newest work, Malthusian Migrations (with @romainwacziarg.bsky.social), soon! 🚨
