But NEW int'l students are down by 17%. Together with the previously reported loss of only 1% for all int'l students, it implies that many existing students must hang on to their visas via internships etc., but this substitution won't last long.

Fewer cheers then, sorry!

Thinking about what keeps people where they are (mobility frictions) improves the measurements of quality of life 👇🏼
How can traditional models fall short in measuring urban appeal? Our analysis reveals that neglecting mobility frictions causes an underestimation of the urban quality-of-life premium (QoL): increasing a region's population is associated with a significant increase in QoL.

Underconfidence in the search for a good school can lead to violations of very basic stability properties of the matching algorithm

New work by @vincentmeisner.bsky.social, @mgesuer.bsky.social and coauthors
How market design can fall short despite strategy-proofness: Our new experiment shows that underconfidence systematically induces significantly more instability (justified envy) than overconfidence in school choice.

Ah, better-than-expected numbers of students

Three cheers to US academia!
The number of foreign students in the U.S. decreased by less than 1 percent this fall, according to new federal data, despite predictions that their enrollment would plummet this year due to a crackdown by the Trump administration.
Trump’s crackdown on foreign students barely impacts enrollment, data shows
About 1.3 million students in the U.S. had active visas in October, down less than 1 percent from a year ago.
