The Inter-Generational Transmission of Cognitive Abilities in Guatemala

This paper examines early childhood development (ECD) outcomes and their association with family characteristics, investments, and environmental factors, with particular emphasis on the inter-generational transmission of cognitive abilities. The paper examines the causal relationship between parental cognitive abilities and ECD outcomes of their offspring using a rich data set from rural Guatemala that can account for such unobservable factors. A 10 percent increase in maternal Raven's scores increase children's Raven's scores by 7. 8 percent. A 10 percent increase in maternal reading and vocabulary skills increases children's score on a standard vocabulary test by 5 percent. Effects are larger for older children, and the impact of maternal cognitive skills is larger than for paternal skills.
