RT journal article T1 Increasing concave orderings of linear combinations of order statistics with applications to social welfare A1 Castaño Martínez, Antonia A1 Pigueiras Voces, Gema A1 Psarrakos, Georgios A1 Sordo Díaz, Miguel Ángel A2 Estadística e Investigación Operativa K1 Increasing concave order K1 Generalized Lorenz order K1 Welfare measurement K1 Order statistics AB We provide in this paper sufficient conditions for comparing, in terms of the increasingconcave order, some income random variables based on linear combinations of orderstatistics that are relevant in the framework of social welfare. The random variablesunder study are weighted average incomes of the poorest and, for some particularweights, their expectations are welfare measures whose integral representations areweighted areas underneath Bonferroni curves.
