Tying the Double-Knot: The Role of Assets in Marriage Commitment
研究发现资产越多的人结婚率越高，可能因为婚姻中资产作为共同财产为育儿投资提供保险，而同居中资产仍属个人，这解释了不同社会经济群体间结婚率的差距。
What explains the growing gap in marriage rates between socioeconomic groups? We present a robust stylized fact not previously documented: marriage rates are higher for individuals with more assets. We argue this may be driven by marriage and cohabitation becoming increasingly similar in a number of ways except for the way assets become marital property to be divided upon divorce in marriage while they remain individual property in the case of cohabitation. We propose that ownership of assets may provide “insurance” to the partner making individually costly, but jointly optimal, investments in children, thus raising the value of marriage.
