Forsaking All Others? the Effects of Same‐Sex Partnership Laws on Risky Sex
利用欧洲国家面板数据，研究同性伴侣法是否降低了性传播感染率，发现该法律显著减少了梅毒发病率，但对淋病和HIV的影响不显著。
One conjectured benefit of a marriage-like legal status for same-sex couples is a reduction in the incidence of sexually transmitted infections (STI). In this study, I discuss how such a policy might influence risky sexual behaviour and STI rates. I also present reduced-form empirical evidence on whether same-sex partnership laws have reduced STI rates, using country-level panel data from Europe. The results suggest that these laws led to statistically significant reductions in syphilis but not in infections that are not sexually transmitted. However, their effects on the incidence of gonorrhoea and HIV were also smaller and statistically imprecise. Copyright © The Author(s). Journal compilation © Royal Economic Society 2008.
