Both in the UK and in the US, we observe puzzling gender asymmetries in the propensity to outmarry: Black men are more likely to have white spouses than Black women, but the opposite is true for Chinese: Chinese men are half less likely to be married to a White person than Chinese women. We argue that differences in height distributions, combined with a simple preference for the husband to be taller than the wife, can help explain these ethnic-specific gender asymmetries. Blacks are taller than Asians, and we argue that this significantly affects their marriage prospects with whites. We provide empirical support for this hypothesis using data from the Millennium Cohort Study. Specifically, we find that ethnic differences in propensity to intermarry with Whites shrink when we control for the proportion of suitable partners with respect to height.
在英国和美国,我们观察到一个令人费解的性别不对称现象,即跨种族婚姻的倾向:黑人男性比黑人女性更有可能与白人配偶结婚,但中国人却恰恰相反:与白人结婚的中国男性比中国女性少一半。我们认为,身高分布的差异,加上简单地偏好丈夫比妻子高的偏好,有助于解释这些特定于种族的性别不对称现象。黑人比亚洲人高,我们认为这会显著影响他们与白人的婚姻前景。我们使用千禧年队列研究的数据为这一假设提供了实证支持。具体来说,我们发现,当我们控制与身高相关的合适伴侣的比例时,与白人通婚的倾向的种族差异会缩小。
