Estimation of Zenga's new index of economic inequality in heavy tailed populations
Francesca Greselin, Leo Pasquazzi · Munich Personal RePEc Archive (Ludwig Maximilian University of Munich) · 2011
In this work we propose a new estimator for Zenga's inequality measure in heavy tailed populations. The new estimator is based on the Weissman estimator for high quantiles. We will show that, under fairly general conditions, it has asymptotic normal distribution. Further we present the results of a simulation study where we compare confidence intervals based on the new estimator with those based on the plug-in estimator.
