A theoretical model is developed to analyse optimal environmental policy when consumer preferences are endogenous. It captures that pollutive consumption is sensitive to consumption by others and commercial advertising. This is conceptualized through a consumption norm. An increase in this norm...

The interaction between habit formation and pollution-type ex- ternalities modifies the social optimum through discount effects and elasticity effects. If the substitution elasticity does not exceed unity, both effects reduce optimal consumption and capital in the long run, and the optimal...

We analyse how market competition in a vertically differentiated polluting industry is affected by product variants that comply at different levels with "green" social norms. A green consumption behaviour is considered as a byword of good citizenship. Consumer preferences depend on a combination...

We consider international negotiations on the level of global pollution, and examine the Lindahl solution which determines the distribution of the pollution permits with unanimous agreement. We show various properties to clarify difficulties to achieve a Pareto efficient allocation as an...

We study an overlapping generations model á la Diamond in which two types of agents are alive at the same time. One type of agents cares about its own level of consumption and an idex of environmental quality, while the other type of agents carse only about its own consumption. At any period,...
