WHO GAINS AND WHO LOSES UNDER THE AMERICAN HEALTH CARE ACT
Matthew Buettgens is a senior research analyst in the Health Policy Center at the
Urban Institute, where he is the mathematician leading the development of Urban’s
Health Insurance Policy Simulation Model (HIPSM). The model is currently being used
to provide technical assistance for health reform implementation in Massachusetts,
Missouri, New York, Virginia, and Washington as well as to the federal government. His
recent work includes a number of research papers analyzing various aspects of national
health insurance reform, both nationally and state-by-state. Research topics have
included the costs and coverage implications of Medicaid expansion for both federal
and state governments; small firm self-insurance under the Affordable Care Act and its
effect on the fully insured market; state-by-state analysis of changes in health
insurance coverage and the remaining uninsured; the effect of reform on employers;
the affordability of coverage under health insurance exchanges; and the implications of
age rating for the affordability of coverage.
John Holahan is an Institute fellow in the Health Policy Center at Urban, where he
previously served as center director for over 30 years. His recent work focuses on
health reform, the uninsured, and health expenditure growth. He has developed
proposals for health system reform, most recently in Massachusetts. He has examined
the coverage, costs, and economic impact of the Affordable Care Act (ACA), including
the costs of Medicaid expansion as well as the macroeconomic effects of the law. He
has also analyzed the health status of Medicaid and exchange enrollees, and the
implications for costs and exchange premiums. Holahan has written on competition in
insurer and provider markets and implications for premiums and government subsidy
costs as well as on the cost-containment provisions of the ACA.
Gordon Mermin is a senior research associate in the Urban-Brookings Tax Policy
Center at the Urban Institute, where he focuses on the tax treatment of retirement
saving, higher education, and health insurance. Mermin develops and maintains the Tax
Policy Center’s microsimulation model of the federal tax system and is part of the
effort to extend the model to state-level analysis. He has written extensively on
retirement policy and work at older ages.
Frank Sammartino is a senior fellow at the Urban-Brookings Tax Policy Center and an
affiliate of Urban’s State and Local Finance Initiative. His current work focuses on the
interaction among federal, state, and local tax policies and on the influence of tax and
transfer policies on income inequality. Sammartino has written extensively about
federal tax and retirement policy issues. In an earlier stint at Urban, he designed and
developed the initial version of the Tax Policy Center microsimulation model, which
researchers use to analyze how federal tax policies affect federal revenues and families
at different income levels. He also led a team of researchers in developing a new
version of the Dynamic Simulation of Income Model, which Urban researchers use to
analyze how public policies and economic and demographic forces shape retirement
income security.
