Eliminating Fares to Expand Opportunities: Experimental Evidence on the Impacts of Free Public Transportation on Economic and Social Disparities
通过随机对照试验，研究为低收入人群提供免费公共交通对其就业的影响，发现临时补贴对工作时长和收入无显著效果，但可能改善财务和身体健康。
We conduct a randomized controlled trial to study the employment effects of providing free public transportation to individuals with low incomes. A temporary subsidy that reduces the price of transit to zero has no significant effects on individuals’ paid hours worked or earnings. Using rich administrative data, we also explore a range of other outcomes. We find suggestive evidence that transit subsidies improve measures of financial and physical health.
