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...

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...

We analyze optimal social discount rates when people derive utility from relative consumption. We compare the social, private, and conventional Ramsey rates. Assuming a positive growth rate, we find that 1) the social discount rate exceeds the private discount rate if the importance of relative...

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...

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

Almost all previous studies on public policy under relative consumption concerns have ignored the role of leisure for status comparisons. Inspired by Veblen (1899), this paper considers a two-type optimal income tax model, where people care about their relative consumption, and where the...

Previous studies on public policy under relative consumption concerns have ignored the role of leisure comparisons. This paper considers a two-type optimal nonlinear income tax model where people care both about their relative consumption and their relative leisure. Increased consumption...

This paper concerns optimal income taxation and provision of a state-variable public good under asymmetric information in a two-type overlapping generations model, where people care about their relative consumption. Each individual may compare his/her own current consumption with his/her own...

This paper concerns optimal income taxation under asymmetric information in a two-type overlapping generations model, where people care about their relative consumption compared to others. The appearance of positional concerns affects the policy choices via two channels: (i) the size of the...
