Impacts of Supermarkets on Farm Household Nutrition in Kenya

Many developing countries experience a food system transformation with a rapid growth of supermarkets. We analyze impacts of supermarkets on farm household nutrition with survey data from Kenya. Participation in supermarket channels is associated with significantly higher calorie, vitamin A, iron, and zinc consumption. We use simultaneous equation models to analyze impact pathways. Supermarket-supplying households have higher incomes, a higher share of land under vegetables, and a higher likelihood of male control of revenues. Furthermore, income and the share of land under vegetables have positive impacts, while male control of revenues has negative impacts on dietary quality. Policy and further research implications are discussed.
