摘要

本文以雙向配對的模擬方法，利用擇偶網站的篩選資料的功能，以兩性「初始的年齡偏好」在既存的各年齡層未婚人口結構之下進行互選，得出兩性各年齡的「年齡被接受度」（符合模擬擇偶者年齡偏好的異性中有多少比率會接受模擬者的年齡）。研究結果顯示：（1）兩性的「年齡被接受度」皆隨著自己年齡的增加而先升後降，最高峰都在29歲，但是女性被接受度劇降的關鍵年齡在30歲而男性在36歲。（2）29歲之前年輕女性的年齡被接受度遠大於男性，29歲之後兩性的被接受度相差不多。本文分析後認為「年齡與資源的交換」（男性較女性易用隨年齡增長的所得替代隨年齡下降的外貌）才是年長男性比年長女性較具擇偶優勢的主因，而非「兩性初始的年齡偏好」、「年齡層未婚人口數」及「未婚男女性別比」。

This paper applies a two-sided matching simulation approach to estimate the ”age acceptance rate” (the percentage of people of the opposite sex who would accept one's age given that one accepts their age), using individual level data including screening criteria on ”initial age preference” in a matching website in Taiwan. The main findings are: (1) Both males and females have their highest age acceptance rate at the age 29, but female's acceptance rates decline quickly after 30, while male's don't decline until 36. (2) Before age 29, young female's age acceptance rates are much higher than young male's. After age 29, both males and females have similar decreasing rates After comparing the ”availability index”, this paper suggests that the advantage of older men in the marriage market may be based on ”age and resource exchange” (a male can use his increasing income to substitute for his decreasing physical attractiveness easier than a female), and nor an ”initial age preference ” or ”population demographics” (the sex ratio and age difference in the unmarried population).
