Holahan is a nationally recognized expert on the Medicaid program, Medicaid and Medicare reform, and coverage, costs, and economic impact of the Affordable Care Act (ACA), including the costs of Medicaid expansion and the macroeconomic effects of the law. Holahan led an effort to develop reform options for the state of Massachusetts and estimate their cost and coverage effects, contributing to the state’s landmark legislation in 2006, which brought it to near universal coverage and laid the groundwork for the ACA.
