Gardín, Carlos;Ray, Debraj; & Esteban, Joan (2007) An Extension of a Measure of Polarization, with an Application to the Income Distribution of Five OECD Countries , Journal of Economic Inequality 5(1): 1–19.

We introduce an extension of the Esteban and Ray [Econometrica, 1994] measure of polarization which can be applied to two types of databases:(i) data for which a density function for the income distribution has already be computed (either parametrically or non-parametrically); and (ii) data which is presented with the population grouped in either income or size intervals.
