I’m on the #EconJobMarket! I study labor, extreme weather adaptation, and inequality. My JMP addresses an under-studied aspect of the labor market: schedule unpredictability among hourly workers in the service sector. 🧵👇

Woah. Argentina's 1990s preschool expansion program appears to have been a smashing success. The program increased high school completion by a whole 11.9 percentage points. The authors estimate that for every $1 spent, the preschool expansion generated about $11 in benefits.

California wants to tax billionaires 5%. But who are they actually taxing? We pulled Forbes 400 data: 90% of CA Forbes billionaire wealth is in tech + finance. Just 4 people (Zuckerberg, Page, Brin, Huang) hold half the CA total. The rest of America's billionaires? Much more
