    A nice illustration of what will happen to US science when we keep out foreign-born

    Our lab lacking everyone non-USA born(middle). Bottom also removes those with foreign-born parents, which includes me. Diversity represented: India, Netherlands, Austria, Germany, Ethiopia, Russia, Haiti, Poland, Brazil, Hong Kong, China, Philippines, Ukraine, Colombia, England!

    Please, someone stop this insanity. This policy will be incredibly costly in terms of lost talent and innovation. Keeping out foreign scientists & students is one of the most effective & insidious ways to run this country into the ground by starving science & innovation.

    Don't let anyone ruin your life over tenure. I had 2 kids at Stanford, plus a disabled mom. Did not get tenure & never regretted it for a second. I only have to look at my kids to see what a ridiculous choice that would have been. My only regret is not spending more time w my Mom

    Scary thought experiment: Snap away all US scientists, like Richard Feynman, whose parents arrived as poor immigrants. As a policy, that's just dumb.

    When I got tenure, I decided to use it start a new research agenda, studying US science in the 20th century, how it became dominant, what held it back, and what we can do better. Here's the first pub (with Scott Kim).

    Analyzing scientists' biographies during the baby boom, we find that mothers have a unique life cycle pattern of productivity. Children reduce the productivity of mothers but not fathers, with important implications for promotions and participation. econometricsociety.org/publications/e…

    US visas to foreign students have dropped by 70%. Not surprising given current policies & atrocious conditions. But so incredibly damaging to science, innovation & growth. Last century, the US became the world's leader in science by attracting foreign talent. Now the US blows it

    So...I just scraped new State Dept data on student visas (F-1's), and it looks like student visa issuance fell by ~70% from FY2019 to FY2020. This is an astounding idiotic own-goal for America, given that education is one of our most successful exports.

    The number of new international students in the US dropped by 45% from the 2019/20 school year to 20/21. If this persists we've reached a turning point for US science and innovation towards decline
    After decades of increases, a drop in the number of international students in the United States

    Super psyched to teach Economics of Innovation in person again this fall - using real-life data on innovation to test for causal effects. Learn to program in R, from scratch. No previous programming experience required

    ;) Saw this in 2 rejections for "Copyright and Creativity." 3rd submission got R&R @JPolEcon, @econfilm made a film, @Freakonomics a podcast. Most importantly though a student wrote yesterday saying they want to do research because of it. So, do what you love and keep going!
