论文摘要
世界各地的国家和城市已诉诸于前所未有的流动性限制，以打击Covid-19的传播。在这里，我们利用了一个自然实验，哥伦比亚城市根据ID号和性别实施了各种锁定政策，以分析这些政策对城市流动性的影响。使用手机数据，我们发现城市移动配额的限制（根据政策建议每天允许的居民份额）与降低移动性无关，我们发现，具有更正式和复杂的工业结构的更大，更富裕的城市的流动性降低了更大的降低。在城市内，较富裕的居民更有可能降低流动性，并且当他们的工作位于富裕或商业/工业形式上正式的邻里时，通勤者尤其更有可能居住。这一发现强调了针对较低收入/非正式工人的缓解需求，并阐明了拉丁美洲城市社会经济阶层之间的关键依赖性。
Countries and cities around the world have resorted to unprecedented mobility restrictions to combat Covid-19 transmission. Here we exploit a natural experiment whereby Colombian cities implemented varied lockdown policies based on ID number and gender to analyse the impact of these policies on urban mobility. Using mobile phone data, we find that the restrictiveness of cities' mobility quotas (the share of residents allowed out daily according to policy advice) does not correlate with mobility reduction Instead, we find that larger, wealthier cities with more formalized and complex industrial structure experienced greater reductions in mobility. Within cities, wealthier residents are more likely to reduce mobility, and commuters are especially more likely to stay home when their work is located in wealthy or commercially/industrially formalized neighbourhoods..Hence, our results indicate that cities' employment characteristics and work-from-home capabilities are the primary determinants of mobility reduction. This finding underscores the need for mitigations aimed at lower income/informal workers, and sheds light on critical dependencies between socioeconomic classes in Latin American cities.
