中文摘要
我们开展了一项随机对照试验, 研究向低收入个体提供免费公共交通的就业效应。一项将公共交通价格降至零的临时补贴, 对个体的有偿工作时长或收入没有显著影响。利用丰富的行政数据, 我们还考察了一系列其他结果。我们发现了提示性证据, 表明交通补贴改善了财务健康与身体健康的相关指标。(JEL G51, J22, J31, L92, L98, R48)
Abstract
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.
