Description This paper highlights results from a follow-up survey of the original sample of program participants, those who are still living in Jamaica as well as those who migrated, 30 years later. We estimate treatment effects on schooling and labor market outcomes using permutation-based statistical inference suitable for the small sample size of the study. We implement block-permutation tests specific to the randomization protocol implemented at the onset of the intervention. We also address a range of issues including the possibility of non-random attrition, multiple outcome hypothesis testing, and the presence of outliers.
Abstract This paper reports the labor market effects of the Jamaica Early Childhood Stimulation intervention at age 31. The study is a small-sample randomized early childhood education stimulation intervention targeting stunted children living in the poor neighborhoods of Kingston, Jamaica. Implemented in 1987–89, treatment consisted of a two-year, home-based intervention designed to improve nutrition and the quality of mother-child interactions to foster cognitive, language, and psycho-social skills. The original sample was 127 stunted children between ages 9 and 24 months. The study was able to track and interview 75 percent of the original sample 30 years after the intervention, both still living in Jamaica and migrated abroad. The findings reveal large and statistically significant effects on income and schooling; the treatment group had 43 percent higher hourly wages and 37 percent higher earnings than the control group. This is a substantial increase over the treatment effect estimated for age 22, when a 25 percent increase in earnings was observed.
