This paper proposes a theory of commodity taxation in the presence of durable goods. Optimal commodity taxes depend on preference nonseparabilities between durable and nondurable consumption. In particular, the seminal Atkinson-Stigliz result fails and differential commodity taxes are optimal...

We study optimal income and commodity tax policy with credit-constrained low-income households. Workers are assumed to receive an even ow of income during the tax year, but make tax payments or receive transfers at the end of the year. They use their disposable income to purchase multiple...

A standard result in the optimal taxation literature is that, when agents differ in market ability and the government aims at redistributing from high- to low-skilled agents by means of an optimal nonlinear labor income tax and a set of commodity taxes, an optimally designed commodity tax...

Deaton (1979) showed that if preferences are weakly separable in goods and labour and quasihomothetic in goods and the government imposes an optimal linear progressive tax, commodity taxes are redundant. Hellwig (2009) generalized the Deaton theorem by showing that the allocation obtained under...

We study commodity taxation in markets where firms, such as Internet Service Providers, energy suppliers and payment card platforms, adopt multi-part tariffs. We show that ad valorem taxes can correct underprovision and hence increase welfare, provided the government applies differentiated tax...

This paper shows that under imperfect competition the welfare effects of indirect tax harmonization may depend crucially on whether taxes are levied by the destination or the origin principle. In a standard model of imperfect competition, while harmonization always makes at least one country...

This paper studies non-cooperative commodity taxation in a trade model with imperfect competition and trade costs. Nationally optimal tax policy simultaneously tries to correct the domestic distortion from imperfect competition and to shift rents to the home country. Importantly, this trade-off...

This paper studies comprehensive national panel data of local option sales taxes at the monthly frequency. I calculate state-by-month population weighted averages of local sales tax rates. I document ten stylized facts concerning the time series patterns and spatial dynamics of local sales...

The paper employs a standard model of dynamic price competition to study how international principles of value-added taxation affect the stability of collusive agreements when producers in an international duopoly agree not to export into each other's home market and tax rates differ across...

We combine consumption generated cross-border pollution and public pollution abatement in a theoretical framework to examine the efficiency of the destination and origin principles of commodity taxation. The key result of our study is that with public pollution abatement, the non-cooperative...
