Moving opportunities: The impact of mixed-income public housing regenerations on student achievement

I use mixed-income public housing regenerations in London as a natural experiment to identify how schools affect low-income students' educational achievement when affluent households flow into their neighborhood. I compare student achievement in schools in the same neighborhood located at different distances from a regeneration before and after its completion. I employ a grandfathering instrument for enrollment in treated schools to address potential endogenous mobility. Students exposed to regenerations have higher test scores at the end of primary school. I estimate that schools explain 65-81% of the overall achievement effects, which are mediated by changes in the student body's composition.
