Abstract

A bias correction method for inequality measures is proposed. The coefficient of variation squared (CV²) is used as an example and its sampling properties, bias, and mean squared error are provided. CV² is shown to be downward biased for positively skewed distributions. A bias corrected estimator is provided.
