What Determines Adult Cognitive Skills? Influences of Pre-Schooling, Schooling, and Post-Schooling Experiences in Guatemala

چکیده
Most empirical investigations of the effects of cognitive skills assume that they are produced by schooling, and that schooling is exogenous. Drawing on a rich longitudinal data set to estimate production functions for adult reading-comprehension cognitive skills and adult nonverbal cognitive skills, we find that (1) Schooling attainment has a significant and substantial effect on adult reading-comprehension cognitive skills but not on adult nonverbal cognitive skills; and (2) Pre-schooling and post-schooling experiences have substantial positive significant effects on adult cognitive skills. Pre-schooling experiences that increase height for age at age six years substantially and significantly increase adult reading-comprehension and nonverbal cognitive skills, even after controlling for schooling attainment and post-school skilled job tenure. Post-schooling tenure in skilled jobs also has a significant positive effect on adult reading-comprehension and nonverbal cognitive skills, although the latter estimate is sensitive to how we treat gender. Age also has significant positive effect but with diminishing returns on adult reading-comprehension cognitive skills. The findings (1) reinforce the importance of early life investments; (2) support the importance of childhood nutrition (“Flynn effect”) and work complexity in explaining increases in cognitive skills; (3) question interpretations of studies reporting productivity impacts of cognitive skills without controlling for endogeneity; and (4) point to limitations in using adult schooling alone to represent human capital.

What Determines Adult Cognitive Skills? Impacts of Pre-Schooling, Schooling and Post-Schooling Experiences in Guatemala
Most investigations of the importance of and the determinants of adult cognitive skills assume that (a) they are produced primarily by schooling and (b) schooling is statistically predetermined. But these assumptions may lead to misleading inferences about impacts of schooling and of pre-schooling and post-schooling experiences on adult cognitive skills. This study uses an unusually rich longit...

In this paper we set out to accomplish several goals. Primarily, we seek to re-interpret Guy Debord’s (1967) work The Society of the Spectacle in light of modern-day schooling, principally within North America (although we recognize the global connectivity inherent in any current discussion of formal education). In addition, we aim to utilize Debord’s conceptualizations as a series of means and...
