Skuteczność głosów preferencyjnych w systemie proporcjonalnym z listami otwartymi

The article presents the usage of the preference votes in open-list proportional representation system (OLPR). The electoral rules condition the effi ciency of the casted votes, i.e. the extent to which the voters’ preferences affect the distribution of seats. In the OLPR system the “wasted votes” may refer not only to the representation of party preferences, but also personal preferences frequently expressing distinct territorial identities. Using the data from Polish Sejm elections, as well as the subnational elections, the authors analyze the usage and outcomes of the preference votes. During the last two decades in Sejm elections the share of effi cient preference votes (casted for the elected representatives) was only slightly higher than the share of votes casted for the losing candidates; in case of the subnational elections, the latter category of votes visibly prevailed. The authors analyze in detail the differences between the elections, parties and Sejm electoral districts, representing various characteristics. Non-parametrical regression analysis provides the list of factors infl uencing the effi ciency of preferential votes, which is generally in agreement with the theoretical expectations. The largest shares of effi cient preference votes may be observed in the districts of a high magnitude, and a lower level of fragmentation (both party and territorial).

National Interests in the European Parliament: Roll Call Vote Analysis

We propose a method for identifying national interests in the European Parliament by comparing roll call vote results with MEPs’ expected ideological positions. We define a new measure – national shift index, corresponding to the magnitude of national delegation’s shift from the aggregate ideological position – which quantifies the influence of the national interest on the voting results. Using this measure, we identify issues characterized by strongest dominance of national factors and compare national delegations’ propensity to vote along national lines.
