We examine the effect on inequality of increasing one income, and show that for two wide classes of indices a benchmark income level or position exists, dividing upper from lower incomes, such that if a lower income is raised, inequality falls, and if an upper income is raised, inequality rises....

The analysis contrasts results of two recently expounded micro-level data approaches to derive robust intertemporal characterizations of redistributional effects of income tax schedules; the fixed-income procedure of Kasten, Sammartino and Toder (1994) and the transplant-and-compare method of...

Tax systems with separate taxation of wage and capital income, also called dual income tax systems, have gained relevance through the Mirrlees Review. Obviously, such tax systems are exposed to horizontal equity (HE) failures, or horizontal inequity (HI). HE and HI have a firm grip on assessment...

Empirical findings on the relationship between income inequality and redistribution from a cross-country perspective are not conclusive. One reason may be that observers have in mind different concepts of redistribution. A major factor is that comparator countries' pre-fisc distributions...

The overall inequality effects of a dual income tax (DIT) system, combining progressive taxation of labor income with proportional taxation of income from capital, are investigated. Simple examples show that correlations between distributions of wage and capital income, the degree of tax rate...

Given an objective to exploit cross-sectional micro data to evaluate the distributional effects of tax policies over a time period, the practitioner of public economics will find that the relevant literature offers a wide variety of empirical approaches. For example, studies vary with respect to...

Which country is most redistributive? This question is often discussed in terms of comparisons of measures of redistribution when each country's tax schedule is applied to its pre-tax income distribution. However, we believe that what most authors have in mind when referring to the "most...

There is confusion in the literature concerning the relationship between income inequality and redistribution in a cross-country perspective. The reason for this is that different contributions in the literature are not referring to the same characteristic. This is shown by addressing...
