When estimating regional inequality, many economists use inequality indices weighted by the regions' shares in the national population. Although this approach is widespread, its adequacy has not received attention in the regional science literature. This paper proves that such approach is...

The paper discusses the ∪-shaped relationship between the equivalence scale n^ε and the Gini index instead of considering the equivalence scale’s relationship to the generalised entropy measures, which was studied by Coulter, et al. (1992). An end-point condition is given for the ∪-shaped...

This paper empirically applies the statistical approaches to the phenomenon of polarization generated by Esteban, et al. (1999) and Gradín (2000) in order to quantify the evolution of the middle class in Mexico and the role of various household attributes in the formation of groups during...

The traditional concept of a strict minimum of necessary consumption and nontaxable income equal for all taxpayers embedded in most current income-tax systems is the result of a paradox of fiscal egalitarianism. The paper shows that substituting the traditional notion of a strict minimum of...

In this paper I will analyse the redistribution of income amongst n generations using the Single-mindedness Theory. I will introduce a new expression for the balanced-budget constraint, no longer based on lump- sum transfers as in the traditional literature, but rather on more realistic labour...

It assesses the impact of the expansion of educational levels on the distribution of wages between 1970 and 1984 in Metropolitan Lima in Peru. For this purpose it uses a dynamic decomposition of the second Theil's concentration index using data from household surveys. The results suggest that...

In this paper I analyse a probabilistic voting model where political candidates choose a direct taxation policy to maximise the probability of winning elections. Society is divided into groups which have di¤erent preferences for consumption of leisure or, in other words, are di¤erently...

This paper explains how to build Lorenz Curves for income distributions and discusses their use for inequality measurement. A short conceptual background, a step-by-step procedure and a simple numerical example illustrate how to calculate and draw Lorenz Curves. A discussion on the use of Lorenz...

This paper illustrates how Crossing Generalised Lorenz (GL) curves can be used to identify the best income distribution on social welfare grounds within a set of alternative income distributions generated by different policy options. It starts by illustrating two alternative income distributions...

This paper analyzes the relationship between mean income and the income of the rich. Our methodology closely follows that of Dollar and Kraay (2002), but instead of looking at the bottom of the distribution, we analyze the top. We use panel data from the World Top Incomes database, which...
