of the Affordable Care Act on health insurance coverage in Medicaid expansion and
non‐expansion states. Journal of Policy Analysis and Management, 36(1), 178-210.
The primary focus of the article is role ACA has played in increasing health insurance
coverage. The overall results show that ACA’s Medicaid expansion increased the number of
insured people by 3.1 percent in 2014. Other components of ACA increase coverage by 2.8
percent. The results are essential to inform the comparison of the impact of Medicaid expansion
and non-expansion states.

Medicaid. Applied Economics Letters, 21(17), 1226-1229.
The article focused on the reason some states declined to expand ACA reforms. It was that the
state with Republic control at both chambers had higher expansion regardless of the cost. The
research also found that undecided states the probability of decision of their decision in the
future can be predicted based on their political side. The research is significant in contributing to
an opinion on various health care controversies and reforms.

women. It was found that most women got access to insurance coverage in states that expanded
the program. The first phase of ACA implementation showed an adjusted 3.9 percent decline in

uninsured women while the second phase of research recorded a 7.4 percent decrease in
uninsured. The number of insured women increased with an increase in Medicaid coverage. The
research will inform the need for health care reforms.

United States. American journal of public health, 108(4), 565-567.
The research investigated how ACA reforms has contributed reduction or increase in
infant mortality. Medicaid was found to have contributed to a significant reduction in infant
mortality in expansion states compared to non-expansion states. The national infant mortality
rates decreased by 11.9 percent. There was a decline in infant mortality in the African Americas
from 12.2 in 2010 to 10.7 in 2015. The decline was attributed to the expansion of Medicaid. The
research was critical in examining the shift in quality and excess to health care in the United
States.
Sharp, A., Jones, A., Sherwood, J., Kutsa, O., Honermann, B., & Millett, G. (2018). Impact
of Medicaid expansion on access to opioid analgesic medications and medication-
assisted treatment. American journal of public health, 108(5), 642-648.
The article focused to establish the impact of Medicaid expansion and Opioid crisis in the
United States. The research tried to connect enhanced health access to increased abuse of opioid
as a prescriptive drug. The article argues that health care reform has increased access to Opioid
analgesic medications. The research found that the rate of opioid prescription increased with the
expansion of Medicaid. The argument forms one of the controversies that need to be addressed
by the reforms.
