TL;DR: The authors showed that the estimates of poverty indices with relative poverty lines are asymptotically normally distributed and that the covariance structure can be consistently estimated in a straightforward manner, which is a result that can be used to test decomposable poverty measures.

TL;DR: In this paper, the authors develop asymptotically distribution-free inference for testing inequality indices with dependent samples, which considers the interpolated Gini coefficient and the generalized entropy class, including several commonly used inequality indices.

TL;DR: In this paper, the effects of using comprehensive income on subgroup poverty rates and on the demographic composition of the poor are investigated for cash and comprehensive income using the official poverty line and six additional poverty lines drawn using thresholds set at 50, 75, 125, 150, 175 and 200 percent of the official level.
Abstract: Recently developed statistical inference procedures for the Sen index and its components – the headcount, income gap and Gini index among the poor – are used to test explicit hypotheses concerning aggregate poverty in the United States for the period 1989 to 1997. Changes in Sen measures of poverty are investigated for cash and comprehensive income using the official poverty line and six additional poverty lines drawn using thresholds set at 50, 75, 125, 150, 175 and 200 percent of the official level. The paper also reports on the effects of using comprehensive income on subgroup poverty rates and on the demographic composition of the poor.

TL;DR: Using the Kolm three-person simplex, it is shown that for a fixed poverty line the power may be increased as higher degrees of stochastic dominance are considered, and for a range of poverty lines the power is reduced as the line increases.
Abstract: This note graphically illustrates the power of various poverty ordering conditions. Using the Kolm three-person simplex, we are able to show that (1) for a fixed poverty line the power may be increased as higher degrees of stochastic dominance are considered, (2) for a single but variable poverty line the power is reduced as the line increases, and (3) for a range of poverty lines the power of the third degree ordering condition may be reduced to that of the second degree if the lower bound poverty line is arbitrarily close to zero.
