Hamory, Joan, Edward Miguel, Michael Walker, Michael Kremer, and Sarah Baird. (2020). "Twenty Year Economic Impacts of Deworming", unpublished working paper.

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 effective respondent tracking rate was 84%. Individuals who received 2 to 3 additional years of childhood deworming experience an increase of 14% in consumption expenditure, 13% in hourly earnings, 9% in non-agricultural work hours, and are 9% more likely to live in urban areas. Most effects are concentrated among males and older individuals. Given deworming's low cost, a conservative annualized social internal rate of return estimate is 37%.

Thanks for sharing this!

From the FP newsletter:

Schools are canceled throughout much of the world due to coronavirus, and that means public health interventions that typically happen at schools aren’t happening at all. The new study from Kenya is just our latest reminder that that is an enormous loss, and the children affected may still be disadvantaged from it 20 years later.

Right now may be a good time to fund a mass deworming effort that doesn't depend on schools.

Speaking of the FP newsletter, I liked the Future Perfect writeup of this story as a plain-language summary of what the researchers found and why it was significant.
