The State Legislature in Maine studied the feasibility of a single-payer health insurance plan. The study estimates that, "under current policy, health care spending in Maine will continue on a path of steady increase - rising by 37% between 2001-4 and by 31% between 2004-8.
The model projects that a single-payer health system would produce a net increase in total health care spending under most benefit designs that we estimated, But that increase in spending would decline over time as the system realized savings through global budgeting, reduction in administrative costs, and enhanced access to primary and preventive care.
Of the single-payer designs that we estimated, some that include consumer cost-sharing would produce net savings in health care spending (relative to projected levels without reform) by 2008.
