We introduce an extension of the Esteban and Ray [Econometrica, 1994] measure of polarization that can be applied to density functions. As a by-product we also derive the Wolfson [AER, 1994] measure as a special case. This derivation has the virtue of casting both measures in the context of a...

The purpose of this paper is two-fold. First, we develop the measurement theory of polarization for the case in which asset distributions can be described using density functions. Second, we provide sample estimators of population polarization indices that can be used to compare polarization...

A classical theme in social analysis views economic class divisions as the main cause of social conflict. Yet many, if not most of the conflicts we observe today appear to be ethnic in nature. It appears that the "vertical" nature of class divisions is often dominated by the "horizontal"...

We develop the measurement theory of polarization for the case in which income distributions can be described using density functions. The main theorem uniquely characterizes a class of polarization measures that fits into what we call the "identity-alienation" framework, and simultanously...

This paper describes how wealth inequality may distort public resource allocation. A government seeks to allocate limited resources to productive sectors, but sectoral productivity is privately known by agents with vested interests in those sectors. They lobby the government for preferential...
