A difference-in-difference approach was used to compare the effects of same-sex domestic partnership, civil union, and marriage policies on same- and different-sex partners who could have benefitted from their partners' employer-based insurance (EBI) coverage. Same-sex partners had 78% lower odds (Marginal Effect = -21%) of having EBI compared with different-sex partners, adjusting for socioeconomic and health-related factors. Same-sex partners living in states that recognized same-sex marriage or domestic partnership had 89% greater odds of having EBI compared with those in states that did not recognize same-sex unions (ME = 5%). The impact of same-sex legislation on increasing take-up of dependent EBI coverage among lesbians, gay men, and bisexual individuals was modest, and domestic partnership legislation was equally as effective as same-sex marriage in increasing same-sex partner EBI coverage. Extending dependent EBI coverage to same-sex partners can mitigate gaps in coverage for a segment of the lesbians, gay men, and bisexual population but will not eliminate them.
采用双重差分法来比较同性家庭伴侣关系、民事结合和婚姻政策对可能受益于其伴侣基于雇主的保险(EBI)覆盖范围的同性和异性伴侣的影响。在对社会经济和健康相关因素进行调整后,与异性伴侣相比,同性伴侣获得EBI的几率低78%(边际效应=-21%)。与不承认同性结合的州的同性伴侣相比,生活在承认同性婚姻或同性家庭伴侣关系的州的同性伴侣获得EBI的几率高89%(边际效应=5%)。同性立法对增加女同性恋者、男同性恋者和双性恋者对受抚养人EBI覆盖范围的接受程度的影响不大,并且家庭伴侣关系立法在增加同性伴侣EBI覆盖范围方面与同性婚姻同样有效。将受抚养人EBI覆盖范围扩大到同性伴侣可以缩小女同性恋者、男同性恋者和双性恋人群中一部分人的覆盖差距,但无法消除这些差距。
