Economic convergence at the sub-national level could have spatially explicit manifestations reflecting convergence clubs and other forms of geographical clustering that are not captured by an overall inequality measure. By decomposing the Theil index of per capita income inequality into between...

The Gini coefficient is a downwardly biased measure of inequality in small populations when income is generated by one of three common distributions. The paper discusses the sources of bias and argues that this property is far more general. This has implications for (i) the comparison of...

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...
