The impact of HIV/AIDS on marriage in the early years of the epidemic
利用双重差分法，以艾滋病死亡率作为感染率的代理变量，发现美国各县艾滋病死亡率越高，1981-1988年间婚姻率上升越大，约增加0.9%。
The advent of the HIV/AIDS crisis transformed the desirability of committed heterosexual relationships. This paper employs a difference-in-differences approach to investigate the impact of the HIV/AIDS crisis on marriage rates. By using HIV/AIDS death rates as a proxy for HIV incidence, the study exploits county-level variations in HIV/AIDS mortality and finds that counties with higher HIV/AIDS death rates experienced larger gains in marriage rates in the early years of the epidemic. Estimates suggest that the virus increased marriage rates by approximately 0.9% in the early years of the virus (1981-1988).
