Abstract

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 better evaluation of the impact
of environmental policies on private consumption and employment. 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.
