Atkinson and Stiglitz (Journal of Public Economics 1976) show that when the government has access to non-linear income taxation and consumer preferences are separable between consumption and leisure, there is no need for differentiated commodity taxation. This paper examines the empirical...

In this paper, we compare ad valorem and specific taxation under heterogeneous demand when a monopolist offers a menu of two-part tariffs. An increase in either tax rate leads to a higher usage fee for all consumers, whereas the fixed fee under reasonable assumptions will fall. If the government...

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 examines the effects of health-oriented food tax reforms on the distribution of tax payments, food demand and health outcomes. Unlike earlier work, we also take into account the uncertainty related to both demand estimation and health estimates and report the confidence intervals for...

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 central result of this paper is that when moral hazard ispresent,competitive equilibrium is almost always (constrained) inefficient. Moral hazard causes shadow prices to deviate from market prices. To remedy this market failure, the government could introduce differential commodity taxation....

A central assumption in public finance is that individuals optimize fully with respect to the incentives created by tax policies. In this paper, we test this assumption using two empirical strategies. First, we conducted an experiment at a grocery store where we posted tax-inclusive prices for...

Recent analyses suggest that cigarette excise taxes lower prenatal smoking. It is unclear, however, whether the association between taxes and prenatal smoking represents a decline among women of reproductive age or a particular response by pregnant women. We address this question directly with...

This paper analyzes the ways in which substituting a consumption tax for the existing personal and corporate income taxes would affect equilibrium pretax interest rates. The analysis indicates that whether the pretax rate of interest rises or falls depends on the strength of the personal saving...

We examine the interplay between market structure and the form that commodity taxation should take in a general equilibrium model in which firms produce differentiated products and so are able to exert market power. Our analysis takes account of two important recent developments that affect...
