Who Gains and Who Loses in the Shift to Electric Vehicles: Impact Assessment through Multi-criteria Multi-stakeholder Analysis

Abstract

Studying the case of the subsidy for electric vehicles in Great Britain (“plug-in car grant”), this research suggests an integrated impact assessment approach by coupling policy issue system modeling with stakeholder preference elicitation.

In particular, we utilize fuzzy cognitive mapping to model the policy issue as a dynamic and complex system. We further simulate the subsidy policy in the model to estimate the changes in select policy aspects. The simulation outcomes are assessed through perspectives of stakeholder groups. For the latter task, nine stakeholder groups were identified and profiled by conducting content analysis and applying the novel CAR method.
