A common objection to "sin taxes"--corrective taxes on goods that are thought to be overconsumed, such as cigarettes, alcohol, and sugary drinks--is that they often fall disproportionately on low-income consumers. This paper studies the interaction between corrective and redistributive motives...

A universal fact of firm-level data is that investment is lumpy: firms either replace a considerable fraction of their existing capital (spike) or do not invest at all (inaction). This paper incorporates the lumpy nature of investment into the study of how tax policy affects investment behavior....

This paper studies commodity taxation in a general model featuring imperfect competition and tax salience. We derive new formulas for the incidence and marginal excess burden of commodity taxation, and we estimate the necessary inputs to the formulas by combining Nielsen Retail Scanner data from...

This paper discusses efficiency considerations underlying the widespread exemption of food from sales and value added taxes, in contrast to the distributional considerations usually used to justify them, analyzing the implications for tax policy. Although there are increasing returns in both...

Ignoring tax avoidance possibilities, a value-added tax and a cash-flow income tax have identical behavioral and distributional consequences. Yet the available means of tax avoidance under each are very different. Under a VAT, avoidance occurs through cross-border shopping, whereas under an...

This paper highlights macroeconomic issues pertinent to the understanding of the international and domestic effects of international VAT harmonization. It outlines elements of the policies of VAT harmonization envisaged for Europe of 1992, and develops a basic tax model which is suitable for the...

The actual value added tax systems used in many countries differ significantly from the completely general VAT that has been the focus of most economic analyses. In practice, VAT systems exempt broad classes of consumer goods and services. This has important implications for the effect of the...

This paper shows that prices respond more to increases than to decreases in Value-Added Taxes (VATs). First, using all VAT reforms from 1996 to 2015 across all European countries we show that prices respond 3 to 4 times more to VAT increases than decreases. Second, using a plausibly exogenous...

This paper shows that accounting for variation in mistakes can be crucial for welfare analysis. Focusing on consumer underreaction to not-fully-salient sales taxes, we show theoretically that the efficiency costs of taxation are amplified by differences in underreaction across individuals and...

We characterize and demonstrate a solution method for an optimal commodity (sales) tax problem consisting of multiple goods, heterogeneous agents, and a nonconvex policy maker optimization problem. Our approach allows for more dimensions of heterogeneity than has been previously possible,...
