Mind the Income Gap: Bias Correction of Inequality Estimators in Small-Sized Samples
关注收入差距:小样本不平等估计量的偏差校正
Income inequality estimators are biased in small samples, leading generally to an underestimation. This aspect deserves particular attention when estimating inequality in small domains and performing small area estimation at the area level. We propose a bias correction framework for a large class of inequality measures comprising the Gini Index, the Generalized Entropy and the Atkinson index families by accounting for complex survey designs. The proposed methodology does not…
