近期最低工资政策及其对出生结果的影响
Recent Minimum Wage Policy and Its Impacts on Birth Outcomes
摘要
After a pause in statutory minimum wage increases during the Great Recession, several states increased minimum wages since 2010, including increases as large as 60% over just a few years. Using a triple difference-in-differences framework and data on the universe of births from 2010 to 2019, this study investigates how recent minimum wage hikes affected birth outcomes. We first document sizeable negative impacts of minimum wage policy on the labor supply and economic well-being of females aged 16-44. We then document small adverse effects on birth outcomes, estimating that minimum wage increases led to lower birthweight, fewer normal birthweight births, and more small for gestational age births. These findings generally contrast with an earlier literature relying primarily on much smaller minimum wage increases which showed more evidence of positive impacts on birth outcomes.
中文摘要
在大衰退期间法定最低工资增长暂停之后，几个州自2010年起提高了最低工资，其中一些州在短短几年内增幅高达60%。本研究采用三重差分框架，并使用2010年至2019年全量出生数据，考察近期最低工资上调如何影响出生结果。我们首先记录了最低工资政策对16—44岁女性的劳动供给和经济福祉产生了相当大的负面影响。随后我们记录了其对出生结果的少量不利影响，估计最低工资上调导致出生体重降低、正常出生体重出生数减少，以及小于胎龄儿出生数增加。这些发现总体上与早期文献形成对比，后者主要依赖幅度小得多的最低工资上调，并显示出更多关于出生结果受到积极影响的证据。
