I'm on the #EconJobMarket! I study how policies and childhood environments shape outcomes of low-income & vulnerable kids.
In my JMP, I study the effects of allowing youth who would have aged out of foster care at 18 to stay until 21—offering support their peers not in foster care get from parents.

(Probably yes, while there's limited causal evidence, the one causal study with comparable data suggests similar effect sizes to the much larger observational literature)

This is good news, but for me, the biggest shock and one of the most under researched areas in development is the stunning rates of sexual abuse *in schools* in many places
Training a single teacher (the "gender focal point") in each school in Mozambique reduced sexual abuse of girls by school staff by 67%
