Abstract: This study exploits a randomized school health intervention that provided deworming treatment to Kenyan children and utilizes longitudinal data to estimate impacts on economic outcomes up to 20 years later. The e ffective respondent tracking rate was 84%. Individuals who received 2 to 3 additional years of childhood deworming experience an increase of 14% in consumption expenditure, 18% in hourly earnings, 8% in non-agricultural work, and are 9% more likely to live in urban areas. Most e ffects are concentrated among males. Given deworming’s low cost, a conservative annualized social internal rate of return estimate is 37%.
