Shortages in healthcare labor markets were a major concern voiced by critics of the 2010 Patient Protection and Affordable Care Act (ACA). Using a difference-in-differences strategy, I find the 2014 ACA Medicaid expansions increased the average workweek by 30 min for registered nurses (RNs) and 50 min for licensed practical nurses (LPNs), driven by an increase in full-time work. RNs and LPNs were 3 and 5 percentage points more likely to work full-time, respectively, due to the Medicaid expansions. There is little evidence of increased nurse employment on the extensive margin.

平价医疗法案医疗补助扩张和护士劳动力市场

2010 年《患者保护和平价医疗法案》(ACA) 的批评者表示，医疗保健劳动力市场短缺是一个主要问题。使用差异中的差异策略，我发现 2014 年 ACA 医疗补助扩展使注册护士 (RN) 的平均每周工作时间增加了 30 分钟，执业护士 (LPN) 的平均每周工作时间增加了 50 分钟，这是由于全职工作增加了。由于医疗补助计划的扩张，RN 和 LPN 全职工作的可能性分别增加了 3 个和 5 个百分点。几乎没有证据表明护士就业增加。
