标题： Green Transition with Dynamic Social Preferences

摘要： 我们考察了一项涉及对棕色商品征税的绿色转型政策，在一个绿色消费偏好由恒定的内在个体部分和不断演变的社会部分组成的经济中。 我们分析了当社会偏好在绿色消费中产生正外部性时的均衡动态，这在政策和偏好之间创造了互补性。 结果表明，考虑到这种外部性相比忽略社会规范效应的政策可以允许更低的税率。 此外，稳定性条件允许在转型路径上逐步降低税率甚至取消税率，从而最小化福利损失。 因此，将政策与偏好互动纳入考虑可以改进绿色转型政策的设计。 显示英文摘要

摘要： We examine a green transition policy involving a tax on brown goods in an economy where preferences for green consumption consist of a constant intrinsic individual component and an evolving social component. We analyse equilibrium dynamics when social preferences exert a positive externality in green consumption, creating complementarity between policy and preferences. The results show that accounting for this externality allows for a lower tax rate compared to policy ignoring the social norm effects. Furthermore, stability conditions permit gradual tax reductions or even removal along the transition path, minimising welfare losses. Thus, incorporating policy-preference interactions improves green transition policy design.
