最近关于存在外部性的税收的若干研究在次优框架下考虑了考虑到环境质量的反馈效应的影响。本文利用欧盟国家可计算的一般均衡模型GEM-E3，探讨了环境政策对健康相关利益的反馈效应的重要性。GEM-E3中实施的建模框架允许通过三个渠道进行反馈：减少医疗支出、增加消费者的可用时间和提高生产部门的劳动生产率。结果表明，对空气污染对消费者和生产者的与健康有关的影响进行显式建模，可以更准确地评估环境政策对私人消费和就业的影响。相对于包含的收益，反馈效应很大。然而，就全球影响而言，与标准的GEM-E3模式相比，反馈的影响很小，因为标准的GEM-E3模式是在事后评估与健康相关的好处。
A number of recent studies on taxation in the presence of externalities in a second-best framework consider the implications of taking into account the feedback effects of environmental quality. This paper explores by means of GEM-E3, a computable general equilibrium model for the EU countries, the importance of the feedback effects of the health related benefits from an environmental policy. The modelling framework implemented in GEM-E3 allows for three channels through which the feedback can occur: a decrease in medical expenditure, an increase in the consumers’ available time and an increase of labour productivity in the production sectors. The results show that the explicit modelling of the health related effect of air pollution on consumers and producers allows for a more precise evaluation of the impact of environmental policies on private consumption and employment. Relative to the included benefits the feedback effects are large. However, in terms of global effect, the impacts of the feedback are small, compared to the standard GEM-E3 model where the health related benefits are evaluated ex-post.
