Technology adoption and risk exposure among smallholder farmers

Panel data evidence from Tanzania and Uganda

This paper investigates the empirical linkages between production risk and technology adoption decisions among agricultural farmers in Tanzania and Uganda using a balanced household panel dataset from the World Bank’s LSMS-ISA project. Applying a moment based approach and a MundlakChamberlain IV fixed effects model to control for endogeneity and unobserved heterogeneity; I find that the first four moments of production significantly explain changes in the probability of adopting chemical fertilizer, improved seeds, and pesticides. While the use of these modern inputs is found to be risk decreasing, estimates suggest that the higher their purchasing costs, the greater the cost of farmers’ private risk bearing. Under the assumption of a moderate risk aversion, the risk premium amounts to 12.7% and 30.5% of the expected production revenues respectively in Tanzania and Uganda, largely explained by production volatility and downside risk aversion. This underscores the need to account for farmers’ preferences towards higher order moments when designing technology adoption policies.
