This paper considers how oral contraception's diffusion to young unmarried women affected the number and parental characteristics of children born to these women. In the short-term, pill access caused declines in fertility and increases in both the share of children born with low birthweight and the share born to poor households. In the long-term, access led to negligible changes in fertility while increasing the share of children with college-educated mothers and decreasing the share with divorced mothers. The short-term effects appear to be driven by upwardly-mobile women opting out of early childbearing while the long-term effects appear to be driven by a retiming of births to later ages. These effects differ from those of abortion legalization, although we find suggestive evidence that pill diffusion lowered abortions. Our results suggest that abortion and the pill are on average used for different purposes by different women, but on the margin some women substitute from abortion towards the pill when both are available.

本文探讨口服避孕药在年轻未婚女性中的普及如何影响这些女性所生孩子的数量及父母特征。短期内,获得避孕药导致生育率下降,低体重出生儿童的比例以及贫困家庭所生孩子的比例上升。从长期来看,获得避孕药对生育率的影响微乎其微,同时增加了母亲受过大学教育的儿童比例,降低了母亲为离异的儿童比例。短期影响似乎是由向上流动的女性选择推迟早育所致,而长期影响似乎是由生育时间推迟到更高年龄所致。这些影响与堕胎合法化的影响不同,尽管我们发现有暗示性证据表明避孕药的普及降低了堕胎率。我们的结果表明,平均而言,不同女性使用堕胎和避孕药的目的不同,但在某些情况下,当两种方式都可行时,一些女性会从堕胎转向使用避孕药。《经济学期刊分类号》:I0、J13、N12。
