. Recent literature stresses the multidimensional nature of income distribution. Two of the most relevant components are inequality and polarization. In this paper, we show the restrictions of keeping simultaneously constant these two aspects whenever the distribution of incomes changes....

Majority voting and social evaluation functions are the main alternatives proposed in the literature for aggregating individual preferences. Despite these being very different, this paper shows that the ranking of income distributions, symmetric under the same transformation, by S-Gini...

This paper proposes a methodology to measure social impact of terrorism. We define a multidimensional terrorism index based not only on deaths but also on other variables such as injuries, bombs and kidnappings. The weight of each terrorist activity is given by its social impact, which is...

We provide a partial ordering view of horizontal inequity (HI), based on the Lorenz criterion, associated with different post-tax income distributions and a (bistochastic) non-parametric estimated benchmark distribution. As a consequence, several measures consistent with the Lorenz criterion can...

. Let us assume a revenue- and inequality-neutral flat tax reform shifting from a graduated-rate tax. Is this reform really neutral in terms of the income distribution? Traditionally, there has been a bias toward the inequality analysis, forgetting other relevant aspects of the income...

. This paper explores the adoption of a probabilistic nonparametric estimator in economics. First, it satisfies the probabilistic coherence principle, which ensures that the estimated variable can be generated by probabilistic assignment modeling from the observed variable. Second, it is proved...

In this article, polarization measurement is presented as a useful tool for characterizing the net transfers of income between individuals caused by a tax reform. The bipolarization measure, which considers just two poles and represents the idea of the disappearance of the middle class, may...

A necessary condition for mobility to reduce the popular desire for redistribution is a significant positive correlation between inequality and mobility. In Prieto et al. (2008), a significant positive relationship was found at the national level. The objective of this study is to establish...

This paper provides a set of sufficient conditions under which the preferences of an egalitarian social decision-maker accord with majority voting. We show that an additive and concave utilitarian social evaluation function is consistent with the outcomes of majority voting if we restrict the...
