We quantify the effects of population aging on the U.S. healthcare system. Our analysis is based on a stochastic general equilibrium overlapping generations model of endogenous health accumulation calibrated to match pre-2010 U.S. data. We find that population aging not only leads to large increases in medical spending but also a large shift in the relative size of private vs. public insurance. Without the Affordable Care Act (ACA), aging by itself leads to a 40% increase in health expenditures by 2060 and a 9.6% increase in GDP which is mainly driven by the increase of the fraction of older higher-risk individuals in the economy as well as behavioral responses to aging and the subsequent expansion of the healthcare sector. Aging increases the premium in group-based health insurance (GHI) markets and enrollment in GHI decreases, while the individual-based health insurance (IHI) market, Medicaid and Medicare expand significantly. The size of Medicare will almost double by 2060 as the elderly dependency ratio increases. Additional funds equivalent to roughly 2.7% of GDP are required to finance Medicare and Medicaid. The introduction of the ACA increases the fraction of insured workers to almost 100% by 2060, compared to 82% without the ACA. This increase is driven by the stabilization of GHI markets and the further expansions of Medicaid and the IHI market. The ACA mitigates the increase of healthcare costs by reducing the number of the uninsured who pay the highest market price for healthcare services. Overall, the ACA adds to the fiscal cost of population aging mainly via the Medicaid expansion. Our findings demonstrate the importance of accounting for behavioral responses, structural changes in the healthcare sector and general equilibrium adjustments when assessing the economy-wide effects of aging.
