Go hard or go home? The limited impacts of "soft" informational policies on pesticide usage in France Paris Dauphine University, France This paper evaluates the impact of the DEPHY network, France's key pesticide reduction policy based on knowledge transmission through model farms, on farmer's pesticide usage. Using a causal framework inspired by the social learning literature, it finds that the DEPHY program reduced pesticide usage by approximately 10% between 2008 and 2021, with the effects concentrated in industrial farming systems such as cereal and mixed (cattle-crop) farms. Indirect transmission effects accounted for no more than 20% of the reduction, highlighting the limited role of social learning in this setting. Through an instrumental variable analysis, it shows that farmers who reduced pesticide use due to the program experienced increased revenue but also faced heightened variability, which could be an obstacle for the adoption of agro-ecological practices by risk-averse farmers. By leveraging fine, individual-level data for heterogeneity analysis, it provides actionable policy recommendations to improve the scheme in the future. | |
