The results from the economic experiments provide the foundation for assumptions used in the agent-based model. Data from geographic information systems and the US Census of Agriculture initialize and parameterize the model. This integrated model enables the exploration of the effects of several policy interventions on technology diffusion and agricultural production and, hence, on agricultural non-point source pollution. Simulation results demonstrate that information ‘nudges’ based on social comparisons increase ambient based policy performance as well as efficiency, especially individual-level tailored information on what others like them have done in past similar situations.en-USExperimental economicsAgent based modelNon-point source pollutionPolicy evaluationFarmer behaviorWorking Paper
