Resumen

In this paper, a new measure of party system nationalisation is proposed. Instead of analyzing the homogeneity of parties’ vote shares across districts within countries, we measure the phenomenon in terms of a combination of the homogeneity of the supply of parties across districts, their electoral results, and the number of seats to be filled in those districts where parties compete. The advantages of our measure of party system nationalisation over the existing measures are illustrated by performing a longitudinal analysis of 256 elections in eighteen Western European countries from 1945 to 1998.
