ACCOUNTING FOR THE TIMING OF FIRST MARRIAGE*
用一般均衡世代交叠搜索模型，证明生育力性别差异是解释美国初婚年龄差（新郎平均比新娘大1.7岁）的关键，收入差异作用次要，并解释了文献忽略的其他初婚时机事实。
Among first marriages in the United States, grooms are on average 1.7 years older than their brides. Traditionally, this fact is explained by sex differences in income. We use a general equilibrium, overlapping generations search model economy to show instead that sex differences in fecundity are essential to account for the age gap at first marriage, whereas sex differences in income play a secondary role. Our model economy also accounts for other facts on the timing of first marriages that the literature has overlooked.
