学院教授关于都市婚恋市场的一项研究

心烦意乱，无聊之中去逛学院的网站，无意中看到了Prof.Zhang的一项关于都市婚恋市场的研究。虽然我已经放弃学术很多年了，但还是忍不住大致看完了研究论文。

故事与数据互相印证，确实是一篇高质量的经济学研究。

以下的该论文的摘要，贴在这里做个备忘吧。

Reports of the difficulties of elite women in finding suitable mates have been increasing despite the growing scarcity of women in China. We show that this phenomenon can be a consequence of women’s preference for men who have higher incomes than themselves. With such a reference-dependent preference,the pool of preferred men shrinks as women’s income increases, while the pool of competing poorer women expands. For high-income (h-)women, even when high-income (H-)men are more plentiful and richer (as in China), the direct effect of a greater number of desirable men can be overwhelmed by the indirect effect of the competitive “entry” of low-income (l-)women. We test for these competitive effects using online dating field experimental, Census, and China Family Panel Studies data. Consistent with competitive entry, the search intensity of beautiful l-women for H-men increases with the sex ratio and the income of H-men, while that of the plain-looking decreases. Notwithstanding the search intensity of h-women for H-men uniformly increases, their probability of marriage decreases with the sex ratio and men’s income relative to low-income women. The decrease is absolute for of plain-looking high-income women. Our evidence is consistent with intra-female competition for spouses who can cover the labour market opportunity cost of marriage and childbirth, which vary with women’s income.

嗯，然后结论是，我找对象应该要找长相普通的，收入比自己低的。按照经济学的模型，这样成功的概率才会更大一些。

爱情？呵呵。经济学不相信爱情，所有的一切都是微观主体之间的互相博弈以及最终形成的均衡罢了，博弈论的英文名起得很好，Game Theory。

Preference benefit and Game，这才是现实。
