摘要：This paper investigates the role of social learning in the diffusion of a new agricultural technologyin a developing country: Ghana. We use unique data on farmers' communication patterns to define eachindividual's information neighborhood, the set of others from whom he might learn. Our empirical strategyis to test whether farmers change their input decisions to align with those of their neighbors who weresuccessful in previous periods. We present evidence that farmers adopt successful neighbors' practices,conditional on many potentially confounding factors including the physical proximity of plots, creditarrangements, clan membership, and soil characteristics.
