I exploit the age-based eligibility structure of Medicare and the age gap between spouses to examine the impact of Medicare eligibility of an older spouse on the insurance coverage of younger, Medicare-ineligible spouses. Using a regression discontinuity framework, I find that Medicare eligibility of an older spouse can crowd-out the health insurance coverage of a younger spouse. Medicare eligibility of older wives increases the likelihood that younger husbands are uninsured. Younger wives are less likely to be covered through an employer-based plan and more likely to have non-group coverage after an older husband turns 65.
我利用医疗保险（Medicare）基于年龄的资格结构以及配偶之间的年龄差距，来研究老年配偶获得医疗保险资格对年轻的、不符合医疗保险资格的配偶的保险覆盖情况的影响。通过使用回归断点框架，我发现老年配偶获得医疗保险资格会挤出年轻配偶的医疗保险覆盖。老年妻子获得医疗保险资格会增加年轻丈夫未参保的可能性。在老年丈夫年满65岁后，年轻妻子通过雇主提供的保险计划获得覆盖的可能性降低，而获得非团体保险覆盖的可能性增加。
