Estimating the Production Function for Human Capital: Results from a Randomized Controlled Trial in Colombia
研究哥伦比亚一项随机早期儿童干预如何通过增加父母投资来提升弱势儿童（12-24个月）的认知和社会情感技能，并估算了技能生产函数。
We examine the channels through which a randomized early childhood intervention in Colombia led to significant gains in cognitive and socio-emotional skills among a sample of disadvantaged children aged 12 to 24 months at baseline. We estimate the determinants of parents’ material and time investments in these children and evaluate the impact of the treatment on such investments. We then estimate the production functions for cognitive and socio-emotional skills. The effects of the program can be explained by increases in parental investments, emphasizing the importance of parenting interventions at an early age.
