City Limits: What Do Local-Area Minimum Wages Do?
分析了城市自行设定最低工资的利弊，基于2010至2020年城市数量从3个增至42个的趋势，评估了地方最低工资对工资、就业及劳动力配置的影响，发现其效果与州或联邦层面类似。
Cities are increasingly setting their own minimum wages, and this trend has accelerated sharply in recent years. While in 2010 there were only three cities with their own minimum wages exceeding the state or federal standard, by 2020 there were 42. This new phenomenon raises the question: is it desirable to have city-level variation in minimum wage polices? We discuss the main trade-offs emerging from local variation in minimum wage polices and evaluate their empirical relevance. First, we document what type of cities raise minimum wages, and we discuss how these characteristics can potentially impact the effectiveness of city-level minimum wage policies. Second, we summarize the evolving evidence on city-level minimum wage changes and provide some new evidence of our own. Early evidence suggests that the impact of the policy on wages and employment to date has been broadly similar to the evidence on state- and federal-level minimum wage changes. Overall, city-level minimum wages seem to be able to tailor the policy to the local economic environment without imposing substantial distortions in allocation of labor and businesses across locations.
