Abstract：
We examine the effects of the Affordable Care Act Medicaid expansions on the employment and work hours of nursing assistants (NAs). We use the 2011-2019 American Community Survey data to identify NAs likely to be affected by Medicaid expansions (income up to 138% of the federal poverty level) in nursing homes and hospitals. Using classical difference-in-differences regressions, we find that Medicaid expansions have little effect on employment and work hours among NAs in the full sample. However, there is a 4.4 percentage-point increase in the probability of working part-time (<30 hours/week) for nursing home NAs (p < .05). We found no employment effects of Medicaid expansions for hospital NAs. Our study adds to the literature on the heterogeneous effects of Medicaid expansions on work effort across occupations and workplaces. The rise in part-time employment for nursing home NAs following Medicaid expansions suggests the need for improved benefits to encourage full-time employment.
摘要：
我们研究了《平价医疗法案》医疗补助计划的扩展对护理助理（NA）的就业和工作时间的影响。我们使用2011-2019年美国社区调查数据来确定可能受到疗养院和医院医疗补助扩展（收入高达联邦贫困水平的138％）影响的NA。使用经典的差异回归，我们发现，在整个样本中，医疗补助的扩大对NAs的就业和工作时间影响不大。然而,疗养院NAs兼职工作（<30小时/周）的可能性增加了4.4个百分点（p<.05）。我们没有发现医疗补助扩大对医院NAS的就业影响。我们的研究增加了有关医疗补助扩展对职业和工作场所工作努力的异质性影响的文献。医疗补助计划扩大后，疗养院的兼职工作增加，这表明需要改善福利以鼓励全职工作。
