Income Inequality and Early Nonmarital Childbearing
利用美国个体数据，研究发现低社会经济地位女性在收入不平等程度更大的地区更可能发生早期非婚生育，且不平等水平差异能解释青少年生育率的地理差异。
Using individual-level data from the United States, we empirically investigate the role of lower-tail income inequality in determining rates of early nonmarital childbearing among low socioeconomic status (SES) women. We present robust evidence that young low-SES women are more likely to have a nonmarital birth when they live in places with larger lower-tail income inequality, all else held constant. We calculate that differences in the level of inequality are able to explain a sizeable share of the geographic variation in teen fertility rates. We propose a model of adolescent decision-making that facilitates the interpretation of our results.
