Fetal Origins and Parental Responses
综述了父母如何根据婴儿出生时的健康禀赋调整投资行为，发现现有证据多表明父母投资会放大初始禀赋差异。
How do parental investments respond to health endowments at birth? Recent studies have combined insights from an earlier theoretical literature on household resource allocation with improved identification strategies to capture causal effects of early life health shocks. We describe empirical challenges in identifying behavioral responses and how recent studies have sought to address these. We then discuss the emerging literature on dynamic complementarities in parental investments arising from the staged, developmental nature of capability production and how capabilities may have multiple dimensions. The bulk of the empirical evidence to date suggests that parental investments reinforce initial endowment differences.
