On March 23, 2010, President Barack Obama signed the Patient Protection
and Affordable Care Act (ACA) into law. This comprehensive health care reform
legislation sought to expand health care coverage to millions of Americans,
control health care costs, and improve the overall quality of the health care
system. The ACA required that all US citizens and legal residents have
qualifying health insurance by 2014. In this paper we give readers a brief
overview of the effects of the ACA based on recent research. We then turn our
attention to the possibility of using the ACA expansion to answer important
underlying questions, such as: To what extent does the holding of insurance lead
to improvements in access to care? To what extent does the holding of coverage
lead to improvements in health? In mental health? Are there likely general
equilibrium effects on labor force participation, hours worked, employment
setting, and indeed even the probability of marrying? By necessity,
researchers’ ability to answer these questions depends on the
availability of data, so we discuss current and potential data sources relevant
for answering these questions. We also look to what has been studied about the
health reform in Massachusetts and early Medicaid expansions to speculate what
we can expect to learn about the effects of the ACA on these outcomes in the
future.
