Proposal for measure of degressive proportionality

Abstract

Degressive proportionality is an intermediary solution between equality and proportionality. Taking this fact into account, the article proposes a measure of degression of the degressively proportional division. The defined measure was used, among other instances, in allocation based on classical proposals of seat distribution in European Parliament by Pukelsheim and Ramirez as well as the distribution of seats during the Parliamentary term of 2014- 2019. The outcome is confronted with other measures functioning in the literature.
