The expansion of supermarkets in developing countries may have far-reaching consequences for poverty and rural development. While previous studies have compared farm profits between participants and non-participants in supermarket channels, wider household welfare effects have hardly been analyzed. Moreover, structural differences between the two groups have been ignored. We address these issues by using endogenous switching regression and building on a survey of vegetable farmers in Kenya. Participation in supermarket channels is associated with a 50% gain in average household income, leading to significant poverty reduction. To realize these benefits on a larger scale will require institutional and policy support.
