One of the goals of school choice is to allow parents to send their children to higher-performing schools. Several studies have shown that distance to school is one of the main determinants of school choice, but challenges to address endogeneity issues remain. To address these concerns, in this paper I take advantage of the construction of a new subway line in Santiago, Chile, that crosses a large area of the city previously unconnected to the subway network. I provide convincing evidence to show that the introduction of the subway line was arguably exogenous for families living close to the new subway stations. With rich administrative data, which includes all high-school seniors that registered to take a national university entrance exam, I use a repeated cross-section difference-in-differences analysis and find that (i) students near the new subway stations travel significantly farther to school than students who live in nearby areas with no subway stations, and (ii) that students near the subway are willing to travel slightly farther to attend schools that perform better in standardized tests, although this effect is small and only significant for language test scores. This set of results is particularly informative in the context of the broader school-choice debate, contributing causal evidence on the effects of transit access on school-choice.

选择学校的目标之一是允许父母将孩子送往表现较好的学校。多项研究表明，距离学校的距离是学校选择的主要决定因素之一，但解决内生性问题仍然面临挑战。为了解决这些问题，在本文中，我利用了在智利圣地亚哥建造的一条新的地铁线的优势，该线跨越了以前未与地铁网络连接的城市大片区域。我提供令人信服的证据表明，对于居住在新地铁站附近的家庭来说，地铁的引入无疑是外来的。拥有丰富的管理数据，其中包括所有注册参加国家大学入学考试的高中生，我使用了重复的横截面差异分析法，发现（i）新地铁站附近的学生到学校的交通要比住在附近没有地铁站的地区的学生远得多，并且（ii）地铁愿意走得更远一些，以参加在标准化考试中表现更好的学校，尽管这种影响很小，并且仅对语言测验成绩有意义。在更广泛的学校选择辩论中，这组结果特别有用，它为过境获取对学校选择的影响提供了因果证据。（ii）地铁附近的学生愿意走得更远一些，以接受在标准化考试中表现更好的学校，尽管这种影响很小，而且仅对语言测验成绩有意义。在更广泛的学校选择辩论中，这组结果特别有用，它为过境获取对学校选择的影响提供了因果证据。（ii）地铁附近的学生愿意走得更远一些，以接受在标准化考试中表现更好的学校，尽管这种影响很小，而且仅对语言测验成绩有意义。在更广泛的学校选择辩论中，这组结果特别有用，它为过境获取对学校选择的影响提供了因果证据。
