The aggressive immigration raids we now see across the nation began 10 months ago in California's Central Valley. Their impact on children, families, and communities is an important & active area of research
I'm pleased my study of the initial raid's early impact on students is now out in @pnas.org

It might be hard to convey to people outside economics just how seismic this is. The Trump effect has most certainly arrived to US academia.

Real change in public expenditures on higher education, 2008 to 2023, selected countries that actually publish the damn data. UK is worst here, but note this does not include RAB (projected future loan forgiveness, basically). If RAB is included...UK would still be last.

Trump does shit every day that should get him impeached. But illegally punishing an entire country — and any Americans who use products or do businesses with anyone in Brazil — because it’s prosecuting its former president for attempting a violent coup is among the worst things he has done.

I'd love to fund studies of interventions that reduce real-time pollution exposure, in the US, on outcomes related to violence and criminal behavior.
(There is strong evidence that such exposure increases violence in real time; the next question is how much interventions can mitigate this effect.)
