INTRODUCTION

Abstract

The purpose of Volume 10 is to collect together original research papers on fiscal policy (taxes and transfers) and inequality. The first two chapters of Volume 10 address methodological issues in tax progressivity measurement. John Creedy examines the questions of to what extent can redistribution be achieved using a structure of consumption taxes with different rates and exemptions. The paper shows that progressivity is maximized when only one commodity group is taxed, the commodity group with the largest total expenditure elasticity. Generalizing this result, Creedy shows that the tax rate should fall as the total elasticity falls. Creedy illustrates his approach using data on Australia’s indirect tax system. In Chapter 2 Lea Achdut, Yasser Awad, and Jacques Silber propose an alternative way to define tax progressivity as a function of marginal, not average tax rates. Changes in tax progressivity indices are usually defined in terms of changes in average tax rates, while changes in tax policy are usually stated in terms of changes in marginal tax rates. Thus, this paper fills a gap between theory and applied work. They apply their approach to study the progressivity of Israel’s National Insurance tax system.
