Long‐Term Care Partnership Effects on Medicaid and Private Insurance
研究了美国长期护理保险合作计划（公私合作推广私人长期护理保险）对保险持有和医疗补助使用的影响，发现该计划使私人保险持有增加1.54个百分点，医疗补助使用减少0.82个百分点，并带来人均约74美元的成本节约。
We examine the impact of the Long-Term Care Insurance Partnership (LTCIP) program-a collaborative initiative between the state-level Medicaid programs and private health insurance companies designed to promote private long-term care insurance (LTCI)-on insurance ownership and Medicaid utilization. We draw on individual-level longitudinal data and employ a difference-in-differences (DD) design adjusted for the staggered implementation of the program between 2005 and 2018. Our results suggest that the rollout of the LTCIP program led to a 1.54 percentage point (pp) (14.7%) increase in LTCI ownership and a 0.82 pp (13.3%) reduction in Medicaid uptake. Our estimates suggest that these combined effects led to an approximate average cost saving of $74 per 65-year-old participant. These findings are explained by a certain degree of substitution between LTCIP and traditional LTCI contracts, ultimately postponing the use of Medicaid benefits.
