Abstract: This article presents a theoretical framework that uses an epidemic diffusion model and a rational choice model to conceptualize the decision to adopt a given technology. We estimate both models on a sample of 114 farmers in Reunion Island. The results show that the diffusion of new drip-irrigation technology was driven by a spontaneous dynamic with collective knock-on effects. In such circumstances, subsidies may quicken diffusion. By contrast, the adoption of an improved, automation-based irrigation technology reflects a rational choice by the most diversified, best informed irrigators with the highest land/labor ratio.
