Assessing the Evidence on Neighborhood Effects from Moving to Opportunity
The Moving to Opportunity (MTO) experiment randomly assigned housing vouchers that could be used in low-poverty neighborhoods. Consistent with the literature, I find that receiving an MTO voucher had no effect on outcomes like earnings, employment, and test scores. However, after studying the assumptions identifying neighborhood effects with MTO data, this paper reaches a very different interpretation of these results than found in the literature. I first specify a model in which the absence of effects from the MTO program implies an absence of neighborhood effects. I present theory and ...

Evidence on the Production of Cognitive Achievement from Moving to Opportunity
This paper performs a subgroup analysis on the effect of receiving a Moving to Opportunity (MTO) housing voucher on test scores. I find evidence of heterogeneity by number of children in the household in Boston, gender in Chicago, and race/ethnicity in Los Angeles. To study the mechanisms driving voucher effect heterogeneity, I develop a generalized Rubin Causal Model and propose an estimator to identify transition-specific Local Average Treatment Effects (LATEs) of school and neighborhood quality. Although I cannot identify such LATEs with the MTO data, the analysis demonstrates that ...

Childhood Exposure to Violence and Nurturing Relationships: The Long-Run Effects on Black Men
Black men who witnessed a shooting before turning 12 have household earnings as adults 31 percent lower than those who did not. We present evidence that this gap is causal and is most likely the result of toxic stress; it is not mediated by incarceration and is constant across neighborhood socioeconomic status. Turning to mechanisms related to toxic stress, we study exposure to violence and nurturing relationships during adolescence. Item-anchored indexes synthesize variables on these treatments better than summing positive responses, Item Response Theory, or Principal Components, which all ...
