The extension of the univariate Lorenz curve to higher dimensions is not an obvious task. The three existing definitions were proposed by Taguchi (1972a,b), Arnold (1983) and Koshevoy and Mosler (1996), who introduced the concepts of Lorenz zonoid and Gini zonoid index. In this paper, using the definition proposed by Arnold (1983), closed expressions for(More)
The aim of this paper is to assess the evolution of multidimensional inequality in well-being using Lorenz curves. Closed expressions for the bivariate Lorenz curve defined by Arnold (1983) are given. We assume a relevant type of models based on the class of distributions with given marginals described by Sarmanov and Lee (Lee, 1996; Sarmanov, 1966). This(More)
