The Impact of Secondary Schooling in Kenya: a Regression Discontinuity Analysis

Journal of Human Resources (2018) 53 (1): 157-188

(Earlier version appears as World Bank WPS 7384, 2015; also available at SSRN.)

Abstract: I estimate the impacts of secondary school on human capital, occupational choice, and fertility for young adults in Kenya. Probability of admission to government secondary school rises sharply at a score close to the national mean on a standardized 8th grade examination, permitting me to estimate causal effects of schooling in a regression discontinuity framework. I combine administrative test score data with a recent survey of young adults to estimate these impacts. My results show that secondary schooling increases human capital, as measured by performance on cognitive tests included in the survey. For men, I find a drop in the probability of low-skill self-employment, as well as suggestive evidence of a rise in the probability of formal employment. The opportunity to attend secondary school also reduces teen pregnancy among women.

Does Africa Need a Rotten Kin Theorem? Experimental Evidence from Village Economies

Review of Economic Studies (2016) 83 (1): 231-268

Joint with Pamela Jakiela

(Earlier version appears as World Bank WPS 6085; also available from SSRN.)

Abstract: This paper measures the economic impacts of social pressures to share income with kin and neighbors in rural Kenyan villages. We conduct a lab experiment in which we randomly vary the observability of investment returns to test whether subjects reduce their income in order to keep it hidden. We find that women adopt an investment strategy that conceals the size of their initial endowment in the experiment, though that strategy reduces their expected earnings. This effect is largest among women with relatives attending the experiment. Parameter estimates suggest that women anticipate that observable income will be "taxed" at a rate above four percent; this effective tax rate nearly doubles when kin can observe income directly. At the village level, we find a robust association between willingness to forgo expected return to keep income hidden in the laboratory experiment, and worse economic outcomes outside the laboratory. Though this paper provides experimental evidence from a single African country - Kenya - observational studies suggest that similar kin pressures may be prevalent in many parts of the developing world.

Monitoring and evaluating the impact of national school-based deworming in Kenya: study design and baseline results

Parasites and Vectors (July 2013) 6:198

Joint with CS Mwandawiro, B Nikolay, JH Kihara, DA Mukoko, MT Mwanje, A Hakobyan, RL Pullan, SJ Brooker, SM Njenga

Abstract: An increasing number of countries in Africa and elsewhere are developing national plans for the control of neglected tropical diseases. A key component of such plans is school-based deworming (SBD) for the control of soil-transmitted helminths (STHs) and schistosomiasis. Monitoring and evaluation (M&E) of national programmes is essential to ensure they are achieving their stated aims and to evaluate when to reduce the frequency of treatment or when to halt it altogether. The article describes the M&E design of the Kenya national SBD programme and presents results from the baseline survey conducted in early 2012.
