Author-workplace-name: GSBE Title: Measuring polarization of preferences Abstract: In this paper, we study the measurement of polarization in collective decision making problems with ordinal preferences over alternatives. We argue that polarization can be measured as an aggregation of antagonisms over pairs of alternatives in the society. We propose a measure of this sort and show that it is the only measure satisfying some normatively appealing conditions. Keywords: Classification-JEL: .
