More than an urban legend: the short- and long-run effects of unplanned fertility shocks
利用哥伦比亚1992年电力配给导致的意外生育增加，研究发现这种冲击不仅缩短了生育间隔、提高了终身生育率，而且12年后受影响女性的社会经济状况更差。
This paper examines the short- and long-run effects of a quasi-exogenous variation in fertility behavior due to a yearlong period of power rationing in Colombia in 1992. We show that power shortages caused a mini baby boom and that the increase in fertility was unplanned and persistent: the time in between births was reduced and overall lifetime fertility increased. We also present evidence suggesting that women who had a baby due to the outage found themselves in worse socioeconomic conditions 12 years later.
