The paper extends Ng’s (1987) model of optimal taxation of diamond goods — goods that are valued solely for their costliness. We extend his findings by analyzing how other goods should be taxed in the presence of pure diamond goods; modified Ramsey rules are derived in a basic single-type...

The probability of income loss depends on talent and effort. Effort has positive externalities and therefore individuals are proportion to their perceived diligence. The social norm requires more effort from individuals perceived as more talented, but talent is private information 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...
