We analyze the effects of a generalized class of negative consumption externalities (asymmetric and non-atmospheric) on the structure of effcient commodity tax programs. Households are not only concerned about consumption reference levels - that is, they gain utility from "keeping up with the...

We introduce cross-border shopping and indirect tax competition into a model of optimal taxation. The Atkinson-Stiglitz result that indirect taxation cannot improve the efficiency of information-constrained tax-transfer policies, and that indirect taxes should not be differentiated across goods,...
