Moving to Opportunity in Boston: Early Results of a Randomized Mobility Experiment
通过随机抽签向高贫困公共住房家庭提供住房券，发现搬迁后家庭安全、户主健康改善，男孩行为问题减少，但就业和收入无显著短期影响。
We examine short-run impacts of changes in residential neighborhoods on the well-being of families residing in high-poverty public housing projects who received Section 8 housing vouchers through a random lottery. Households offered vouchers experienced improvements in multiple measures of well-being relative to a control group, including increased safety, improved health among household heads, and fewer behavior problems among boys. There were no significant short-run impacts of vouchers on the employment, earnings, or welfare receipt of household heads. Children in households offered vouchers valid only in low poverty neighborhoods also had reduced likelihood of injuries, asthma attacks, and victimizations by crime.
