Measuring Progressivity and Inequality
A general class of progressivity indices is proposed which is consistent with the well-developed theory of the measurement of inequality and social welfare. In particular, we show that the more progressive a tax system, the more equal the distribution of net income and the greater the progressivity index. For an additive social welfare function and a progressive tax system, the greater the degree of relative inequality aversion, the greater the progressivity index. We also discuss the link between inequality of gross income and tax progressivity. A by-product is the derivation of a general class of inequality measures that are invariant to equi-proportionate changes in incomes. We illustrate the analysis using the British tax and benefit system.
