Estimating Social Effects in Matching Markets: Externalities in Spousal Search
研究在婚姻市场中，当潜在配偶数量增加时，人们结婚意愿下降的现象，并开发了一种简化方法识别这种双向匹配市场中的溢出效应。
This paper investigates the hypothesis that individuals are less willing to marry when there are more potential partners to search amongst, and thus when others are also less prone to marry. To do this, it develops a reduced-form method [a variation on Manski's (1993) model] that allows identification of such spillovers in two-sided matching markets. Estimates from this method are internally consistent, unbiased, robust to different definitions of the marriage market, and large enough to warrant attention. Additional evidence suggests that the effect works via the proposed search mechanism. © 2003 President and Fellows of Harvard College and the Massachusetts Institute of Technology.
