RT Journal Article SR Electronic T1 Cognitive Development among Young Children in Ecuador JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 49 OP 84 DO 10.3368/jhr.XLII.1.49 VO XLII IS 1 A1 Christina Paxson A1 Norbert Schady YR 2007 UL http://jhr.uwpress.org/content/XLII/1/49.abstract AB We examine the relationship between early cognitive development, socioeconomic status (SES), child health, and parenting quality in a developing country. We use a sample of more than 3,000 predominantly poor preschool-aged children from Ecuador, and analyze determinants of their scores on a widely used test of language ability. We find that household wealth and parental education are associated with higher scores, and that these associations are larger among older children. Child health and measures of parenting quality are associated with test performance, and account for a fraction, although not the majority, of the association between SES and cognitive development.
