FERTILITY RISK IN THE LIFE CYCLE
研究生命周期中生育决策的时间选择，特别是生育和流产的时机，构建了包含收入冲击和不完美生育控制的消费储蓄与生育模型，对理解生育政策有参考价值。
In this article, I study fertility decisions with special emphasis on the timing of births and abortions over the life cycle. Given the policy debate regarding abortion availability and recent evidence of its positive impact on women's outcomes, understanding the fertility process should help guide the discussion. Here, I present a life‐cycle model of consumption–savings and fertility decisions in an environment with uninsurable income shocks and imperfect fertility control. My model presents a framework in which both opportunity costs of child rearing and technological restrictions (in the form of contraception effectiveness) have roles shaping lifetime fertility choices.
