Global environmental problems are often assumed to imply extensive inefficiencies since there is no global authority corresponding to the government at a national level. This paper shows, on the contrary, that rich countries in a free unregulated market may still undertake globally efficient...

This paper analyzes optimal differential commodity taxation, together with optimal nonlinear income taxation, in order to deal with positional preferences. It also derives the optimal public provision of private goods both when differential commodity taxation is feasible and when it is not. It...

This paper derives Pareto efficient policy rules for the provision of national as well as global public goods in a two-country world, where each individual cares about relative consumption within as well as between countries. Furthermore, we compare these policy rules with those that follow from...

This paper concerns the optimal provision of a state-variable public good, where the global climate is the prime example. The analysis is based on a two-type optimal income tax model with overlapping generations, where people care about their relative consumption. We consider both...

Recent empirical evidence suggests that between-country social comparisons have become more important over time. This paper analyzes optimal income taxation in a multi-country economy, where consumers derive utility from their relative consumption compared with both other domestic residents and...

Much evidence suggests that people are concerned with their relative consumption, i.e., their consumption in relation to the consumption of others. Yet, the social costs of conspicuous consumption have so far played little (or no) role in savings-based indicators of sustainable development. The...

The optimal provision of a state-variable public good, where the global climate is the prime example, is analyzed in a model where people care about their relative consumption. We consider both keeping-up-with-the-Joneses preferences (where people compare their own current consumption with...
