We propose a first order bias correction term for the Gini index to reduce the bias due to grouping. The first order … correction term is obtained from studying the estimator of the Gini index within a measurement error framework. In addition, it … reveals an intuitive formula for the remaining second order bias which is useful in empirical analyses. We analyze the …
