The choice of a suitable weight function is a feasible and desirable direction for inequality comparison. This paper proposes a new class of indices based on a ratio of two L-statistics in which the weight function in the numerator involves the expected values of order statistics from a random variable describing the normative attitude to the measurement of inequality. Also, the article describes and discusses a graphical technique, based on the QQ plot, which is useful to select the most appropriate theoretical frequency distribution. A large-scale Monte Carlo study has been conducted to assess the sampling and asymptotic properties of some of a number of inequality indices. The simulations showthat the newclass is able to provide indices that compete well with the traditional measures of income inequality and industrial concentration.
