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,...

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...

Tech giants such as Google and Facebook generate significant amounts of advertising income, which is mainly reported in low-tax countries. This has created a policy discussion of how to re-align the location of value creation and taxation. The success of the business model of these digital...

The existing literature suggests that the concern for economic efficiency calls for individual taxation of married couples with a higher rate on the primary earner. This paper reconsiders the choice of tax unit in the Becker model of household production, which includes previous analyses as...

This articles studies the optimal tax mix (taxes on income and commodities) under asymmetric information in a two-type model, when individuals make relative consumption comparisons. The model includes both positional and nonpositional goods, taking into account the fact that relative concerns...

This paper extends the previous literature on optimal redistributive taxation in the presence of externalities to a multi-externality setting. While taxes on income and on 'clean' commodities are still unaffected by the externalities, which confirms previous results, I find that the existence of...

This article incorporates tax evasion into an optimum taxation framework with individuals differing in earning abilities and initial wealth. We find that despite the possibility of its evasion a tax on initial wealth should supplement the optimal nonlinear income tax, given a positive...

We study the optimal tax system in a dynamic model where differences in wages induce differences in inheritances, and the transition from parent ability to child ability is described by a Markov chain. We characterize expected inheritances in the steady state and show that the Atkinson-Stiglitz...

We analyze Pareto-efficient tax breaks for work-related expenses in a Mirrleesian environment. Individuals are heterogenous in their ability. In addition to a labor-leisure choice, they decide how to spend their money between normal consumption and work-related goods. We derive an efficiency...
