Following Milanovic's (1997) paper [Economics Letters, vol. 56, p. 45-49], we propose a simple way to compute the Gini index when income y is a quadratic function of its rank among n individuals.

We assess whether global social welfare has improved in the last decades despite (or because of) the substantial increase in global population. We use for this purpose a relatively unknown but simple and attractive social evaluation approach called critical-level generalized utilitarianism...

The evaluation of development processes and of public policies often involves comparisons of social states that differ in income distributions, population sizes and life longevity. This may require social evaluation principles to be sensitive to the quality, the quantity and the duration of...

In this paper, we propose a new multidimensional inequality index that satisfies a fundamental set of desired properties. We discuss the case where the social evaluation function of welfare depends simultaneously on unidimensional and multidimensional forms of inequality. We show how this mixed...

Using a large sample of US urban areas, we provide systematic evidence that mean household income rises with city ('agglomeration'), that this effect is stronger for the top of the income distribution ('polarization'), and that household income inequality increases at a decreasing rate in city...

We investigate how to make poverty comparisons using multidimensional indicators of well-being, showing in particular how to check whether the comparisons are robust to aggregation procedures and to the choice of multidimensional poverty lines. In contrast to earlier work, our methodology...

We propose a general class of indices of horizontal inequity that complements existing classes of progressivity and vertical equity indices. The class of horizontal inequity indices can also correct for biases in measuring a general class of inequality measures. We illustrate our results using...

Income inequality measures involve two sub-classes of decomposable measures: those decomposed by sub-groups and those decomposed by income source. The former enables one to compute between- and within-group indices. The latter allows for gauging the inequality related to each factor of income...

The purpose of this paper is to show that the Gini index of equality is: (i) subgroup decomposable throughout interpersonal comparisons; (ii) decomposable by income source; (iii) decomposable both by subgroup and income source; (iv) and decomposable in a multidimensional context permitting...

The federal government announced in its 2012 budget its intention to delay the age of eligibility for Old Age Security and the Guaranteed Income Supplement from 65 to 67 years. By the time the policy is fully implemented (i.e., in 2030), this delay will have increased net revenues of the fedral...
