However, interest in more comprehensive health care reform such as a single-payer system has persisted. Definitions of single-payer systems are heterogeneous, and estimates of the effects on spending vary. The objectives of this dissertation were to understand single-payer proposals and to estimate health care spending under single-payer alternatives in the United States. Single-payer proposals are wide-ranging reform efforts spanning financing and delivery, but vary in the provisions. I modeled two sets of national scenarios – one labeled comprehensive and the other catastrophic – and compared insurance coverage and spending relative to the ACA in 2017. First, I estimated the effects of utilization and financing changes, and then I added the effects of “other savings and costs” relating to administration, drug and provider prices, and implementation. Due to coverage of all legal residents and low cost sharing and prior to adjusting for other savings and costs, the comprehensive scenario increased national health care expenditures by $435 billion and federal expenditures by $1 trillion relative to the ACA. The range of the net effect of the other savings and costs in the literature was $1.5 trillion in savings to $140 billion in costs, with a mean estimate of $556 billion in savings. If this mean estimate was applied to the comprehensive scenario, national expenditures would be $121 billion lower but federal expenditures would still be $446 billion higher relative to the ACA. The catastrophic scenario also covered all legal residents but increased overall cost sharing, resulting in a reduction in national expenditures by $211 billion and federal expenditures by $40 billion even before adjusting for other savings and costs. Average household spending on health care in both sets of scenarios could be more progressive by income than spending under the ACA. I also developed an interactive, web-based cost tool that allows the savings and cost assumptions to be adjusted by any user. As the debate on how to finance health care for all Americans continues, this study provides increased transparency about economic evaluations of health care reform. iii Table of Contents Abstract .................................................................................................................................... iii Figures...................................................................................................................................... vii Tables ........................................................................................................................................ ix Summary ................................................................................................................................... xi Acknowledgments.................................................................................................................... xv Abbreviations ......................................................................................................................... xvii 1.
