Over the last two decades many airline markets have been deregulated, resulting in increased competition and use of different types of networks. At the same time there has been an intense discussion on environmental taxation of airline traffic. It is likely that an optimal environmental tax and...

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...

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...

We examine the choice of policy instrument price, quantity, or a mix of the two when two pollutants are regulated and firms’ abatement costs are private information. A key parameter that affects this choice is the technological externality between the abatement efforts involved, i.e., whether...

Earlier research has shown that using a default option has a decisive effect on individuals’ choices. In many cases, however, the low proportion of subjects who switch from the pre-set default option might partly explained by inexperience with the goods or services offered, and high...

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 nonlinear taxation in an OLG model with two ability-types, where people care about their own consumption relative to (i) other people’s current consumption, (ii) own past consumption, and (iii) other people’s past consumption. We show that intertemporal...
