| Summary: | This paper investigates whether a
large-scale deworming intervention aimed at primary school
pupils in western Kenya had long-term effects on young
children in the region. The paper exploits positive
externalities from the program to estimate the impact on
younger children who did not receive treatment directly. Ten
years after the intervention, large cognitive effects are
found -- comparable to between 0.5 and 0.8 years of
schooling -- for children who were less than one year old
when their communities received mass deworming treatment.
Because mass deworming was administered through schools,
effects are estimated among children who were likely to have
older siblings in schools receiving the treatment directly;
in this subpopulation, effects are nearly twice as large. |
