Abstract
This project will create a dataset consisting of the children of individuals who themselves previously benefited from a randomized health (deworming) program. The project will exploit experimental variation to estimate the causal impact of this earlier program on the health and cognitive development of the recipients’ children, overcoming the key methodological problem of confounding. The project will survey approximately 1,500 children of the 7,500 respondents in the Kenya Life Panel Survey (KLPS), creating the new KLPS-Kids dataset, to estimate the extent to which a health program can help break the intergenerational transmission of poverty.

Experimental Design

Experimental Design
The project will survey a randomly selected subset of approximately 1,500 children aged 3-5 of 7,500 adult respondents in the Kenya Life Panel Survey (KLPS), creating the new KLPS-Kids dataset. The original KLPS sample contains Kenyans who participated in an earlier health study, known as the Primary School Deworming Program (PSDP). The PSDP provided deworming medication to primary school students in rural western Kenya starting in 1998, where the order of phase-in to primary schools was randomized. Previous research finds that this intervention had substantial positive impacts on the health, schooling and labor market hours and earnings of beneficiaries 10 years after the launch of the program. These impacts on parents are a necessary pre-condition for studying later impacts among recipients’ children, and to estimate the extent to which a health intervention can help break the intergenerational transmission of poverty by improving life outcomes for program beneficiaries’ children. In order to measure the impacts on the recipients’ children, this project will create locally appropriate versions of both standard and innovative survey instruments designed to measure various domains of development among children aged 3-5. Since the selection of beneficiaries for the PSDP was randomized, the data will enable the estimation of causal impacts of this program on recipients’ children’s outcomes, overcoming the key methodological problem of confounding.
Experimental Design Details
Randomization Method
The randomization performed for the PSDP is described in Miguel et al. (2014), "Worms: Identifying Impacts on Education and Health in the Presence of Treatment Externalities,Data User's Guide", Center for Effective Global Action Working Paper #40. The current project will seek children aged 3-5 of a randomly selected half of adult PSDP/KLPS participants (where randomization is done by computer). Up to 2 children will be interviewed per eligible adult. In cases where the adult has more than two children aged 3-5, children to be interviewed will be randomly chosen using a die roll by the survey enumerator.
Randomization Unit
The adults were randomized into the PSDP at the school level. Adults and children chosen for followup in the present project are randomized at the individual level.
Was the treatment clustered?
Yes
