KLPS has generated impactful research published in leading journals across diverse fields such as economics, public health, psychology, and more. Explore some of the key publications below to dive into the insights and findings from this groundbreaking study. Some of the core papers include:
- Cohort Profile: Kenya Life Panel Survey (International Journal of Epidemiology, 2026): Provides a comprehensive overview of the KLPS cohort, covering data collection across survey rounds for both the original respondents and the subset of their children. It documents the topics covered in each round, reports tracking and attrition rates, and benchmarks the sample against nationally representative Kenyan data.
- Worms: Identifying Impacts on Education and Health in the Presence of Treatment Externalities (Econometrica, 2004): Provides essential background on the Primary School Deworming Project (PSDP), including the study setting and population, research design, the intervention, and information on intestinal worms. It also develops a statistical approach to estimating spatial spillovers that has been influential in subsequent research, including in recent work on the spillover effects of cash transfers.
- The Illusion of Sustainability (Quarterly Journal of Economics, 2007): Investigates the impacts of a cost-sharing program within the PSDP on the demand for deworming medication, and utilizes the study’s randomized design to estimate peer effects in take-up.
- Worms at Work: Long-run Impacts of a Child Health Investment (Quarterly Journal of Economics, 2016): Examines the 10-year follow-up effects of school-based deworming on individual education, health, and labor market outcomes, and examines the intervention’s cost effectiveness and fiscal implications, using the KLPS-2 data round.
- Twenty Year Economic Impacts of Deworming (Proceedings of the National Academy of Sciences, 2021): Analyzes long-term effects of child deworming on earnings, consumption, and urban migration, using the KLPS-3 and KLPS-4 data rounds, and finds larger labor market gains among males.
