Using household level data from rural Kenya, this article explores whether and how farm households respond to unfavorable agricultural production environments, including any ex post adjustments in off-farm labor supply in response to unexpected weather shocks. While controlling for a wide range of educational, demographic, and other locational factors, we examine how long-term weather conditions and specific rainfall shocks influence a household's decision to engage in, and their earnings from, the off-farm labor market. We find that rural households engage in off-farm work as a long-term strategy to deal with the effects of anticipated weather conditions on their farming operations. The analysis does not reveal major short-term adjustments in off-farm engagement as a result of specific, unexpected rainfall shocks; these households do however rely on remittance income and petty agricultural wage labor under these circumstances. Holding other factors constant, and conditional on participation, households in areas with a more productive local agriculture tend to earn more from off-farm work especially in the informal/business sector than their counterparts in regions with a less productive agriculture. As expected, a vibrant local economy in the form of public investment increases the probability of off-farm participation.
