The city of Fernandópolis, located in the countryside of the state of São Paulo, Brazil, imposed a juvenile curfew in 2005. This decision was not made at the municipal or state level, but in a courtroom. Subsequently, other municipalities in the state of São Paulo decided to adopt a juvenile curfew. To assess the effect of the curfew on reducing crime, this paper uses the difference‐in‐differences estimation to compare its impact, relative to municipalities that did not adopt a curfew. The results suggest that the curfew led to a decrease of 17.9% in thieves per thousand inhabitants in municipalities that adopted it.

青少年宵禁和减少犯罪：来自巴西的证据

位于巴西圣保罗州乡村的费尔南多波利斯（Fernandópolis）市于2005年实行了宵禁。这项决定不是在市或州一级做出的，而是在法庭上做出的。随后，圣保罗州的其他市镇决定采用宵禁。为了评估宵禁对减少犯罪的影响，本文使用差异差异估计来比较其相对于未采用宵禁的城市的影响。结果表明，宵禁使采用该宵禁的城市每千名居民的窃贼数量减少了17.9％。
