中文摘要

我们研究社会规范如何塑造生命早期经历中国大饥荒对性别不平等的影响。我们建立模型,刻画社会规范如何与不利冲击相互作用,影响男性和女性的存活概率,并影响随后的人力资本投资。我们使用包含出生地信息的2000年中国人口普查数据,对这些预测进行实证检验,并估计一个双重差分模型,将饥荒暴露程度在出生队列之间和地区之间的差异与男孩偏好文化的地区差异相结合。我们发现,男孩偏好缓冲了宫内饥荒冲击对出生队列男女性别比的负面影响,但实际上减弱了饥荒对健康和教育方面性别不平等的影响。

Abstract

Abstract We study the influence of social norms in shaping the impact of early life exposure to China’s Great Famine on gender inequality. We model how social norms interact with adverse shocks to affect male and female survival chances and influence subsequent human capital investments. We test these predictions empirically by using the 2000 China Population Census that has information on birthplace and estimate a differencein-differences model that combines cohort and regional variation in exposure to the famine with regional variation in the culture of son preference. We find that son preference buffers the negative impact of intrauterine famine shocks on cohort male- to-female sex ratios but actually reduces famine’s impact on gender inequality in health and education.
