理论表明，较长的预期寿命会鼓励教育投资，因为较长的时间范围会增加随着时间的推移而支付的投资价值。为了估计这一影响的程度，我们研究了1946年至1953年期间斯里兰卡孕产妇死亡率的突然下降，这大大增加了女孩的预期寿命。我们评估了在孕产妇死亡率下降幅度较大的地区，女童教育相对于男童教育的增长幅度是否更大。我们发现，预期寿命每增加一年，识字率增加0.7个百分点（2%），受教育年限增加0.11年（3%）。
Theory suggests that longer life expectancy encourages educational investment because a longer time horizon increases the value of investments that pay out over time. To estimate the magnitude of this effect, we examine a sudden drop in maternal mortality in Sri Lanka between 1946 and 1953, which sharply increased the life expectancy of girls. We assess whether girls' education relative to boys' increases more in areas with larger maternal mortality declines. We find that for every extra year of life expectancy, literacy increases by 0.7 percentage points (2%) and years of education increase by 0.11 years (3%).
