Education and Adult Cognition in a Low-Income Setting: Differences among Adult Siblings
利用印尼家庭生活调查数据，通过比较成年兄弟姐妹来排除遗传和家庭背景等共同因素，发现教育对成人认知有显著正向影响，而教育与身高的正相关则完全由家庭背景解释。
The relationship between completed education and adult cognition is investigated using data from the Indonesia Family Life Survey. We compare adult siblings to account for shared, difficult-to-measure characteristics that likely affect this relationship, including genetics and parental preferences and investments. After establishing the importance of shared family background factors, we document substantively large, significant effects of education on cognition in models with sibling fixed effects. In contrast, the strong positive correlation between education and adult height is reduced to zero in models with sibling fixed effects, suggesting little contamination in the education-height association beyond factors common to siblings.
