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...

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...

We examine the effect of addictive behavior on a socially optimal environmental tax. If utility in part depends on past consumption and individuals are time-consistent, the socially optimal environmental tax is shown to be equal to the conventional Pigovian tax. In a second-best world where the...

We analyze how habit formation affects optimal environmental taxation, when consumption of a habitual good causes a negative external effect on the environment. In a simple two-period model, we show that optimal taxation is still Pigouvian, where tax rates equal marginal damage in each period....

Gold is frequently mined in rainforests that can provide either gold or forest benefits, but not both. This conflict in resource use occurs in Ghana, a developing country in the tropics where the capital needed for mining is obtained from foreign direct investment (FDI). We use a dynamic model...
