Marrying Up: The Role of Sex Ratio in Assortative Matching
利用一战对法国男性数量造成的巨大冲击，研究男性稀缺如何影响婚姻匹配、结婚率、非婚生育、离婚率和年龄差距，发现男性稀缺时其婚姻市场地位提升。
We assemble a novel dataset to study the impact of male scarcity on marital assortative matching and other marriage market outcomes using the large shock that WWI caused to the number of French men. Using a difference-in-differences approach, we find that postwar in regions with higher mortality rates: men were less likely to marry women of lower social classes; men were more likely and women less likely to marry; out-of-wedlock births increased; divorce rates decreased; and the age gap decreased. These findings are consistent with men improving their position in the marriage market as they become scarcer.
