Atkinson and Stiglitz show that with weakly separability, differential commodity taxes are unnecessary given an optimal nonlinear income tax. Deaton showed that with an optimal linear progressive income tax, commodity taxes are superfluous under weakly separable and linear Engel curves. Using...

This paper addresses two fundamental issues in indirect tax design. It first revisits the case for reduced rates on items especially important to the poor, establishing conditions under which even very crudely targeted spending measures better serve their interests. It then explores the welfare...

This paper analyzes the welfare effects of altruism on the optimal fiscal policy. The existence of positive bequests links present and future generations in the economy. We show that these altruistic links provide a new role for indirect taxation (consumption and estate taxes) with important...

This paper identifies conditions under which, starting from any tax distorting equilibrium, destination- and origin-based indirect tax-harmonizing reforms are potentially Pareto improving in the presence of global public goods. The first condition (unrequited transfers between governments)...

The potential impact of smart cards is examined in the context of a standard model of direct and indirect taxation. The distinction between the two types of tax is made in terms of the information required to implement them. Electronic cards in general are understood as devices for enriching and...

An important question is whether VAT exemption of financial services is a desirable property or whether it is justified only due to practical and administrative necessity. This paper singles out a number of financial services for discussion of this issue in a context allowing for other taxes and...

This paper analyzes the effects of specific and ad valorem taxation in an industry with downstream and upstream oligopoly. We find that in the short run, i.e. when the number of firms in both markets is exogenous, the results concerning tax incidence tend to be qualitatively similar to models...

This paper examines the case for internationally coordinated indirect taxes on aviation (as a source of general revenue-not (necessarily) as a source of development finance). The case for such taxes is strong: the tax burden on international aviation is currently limited, yet it contributes...

This paper evaluates the impact of globalization on tax bases of countries at varying stages of development. We see globalization as a process that induces countries to embrace greater trade and financial integration. This in turn should shift their tax revenue from quot;easy to collectquot;...

There is an ongoing extensive debate, virtually touching each jurisdiction, regarding the levy of taxes on digital services. Each country, especially the Source countries which have an extensive consumer base of digital services, is grappling with the increasing pressure to tax such services...
