Party-switching Between Elections is Influenced by Polarization, not the Number of Parties
Party-switching Between Elections is Influenced by Polarization, not the Number of Parties Yves Dejaeghere and Ruth Dassonneville In 1979 Mogens Pedersen published a seminal paper in which he analyzed the impact of party-system variables on inter-electoral volatility. By means of an analysis of aggregate data from over 100 elections, he concluded that the number of parties increases volatility. Although Pedersen tested his hypothesis with the best data available at the time, they were actually not ideal to do so, as he indicated himself that his hypotheses implied ‘a test on the basis of individual level data’ (Pedersen, …

Postcard from the Field Post-election Survey 2016 in Slovakia: Manifolds Challenges to Voters’ Memory Olga Gyarfasova This is the first of our Postcards from the Field series. CSES collaborators provide an update and commentary on election studies recently in the field. In general, election results are getting more and more unexpected. It is due to growing voters’ volatility, increasing portion of late-deciders, or changes on the political scene (e.g. due to the formation of new parties). High electoral volatility is further catalyzed by social media channels that have proven to be extremely effective in generating quick though often short-lived voter …

The Tough Decision to Remove Political Knowledge from the CSES Module 5 By Elisabeth Gidengil and Elizabeth Zechmeister Political information questions will be absent from the CSES core module for the first time with the 5th installment of the CSES module. The CSES Planning Committee’s Political Knowledge Subcommittee[1] reached this decision despite shared agreement that political knowledge is a venerated workhorse in the field of voter choice. Differences exist among those high and low in political knowledge in numerous domains, such as economic voting behavior and the use of heuristic aids in voting decisions (though exceptions exist). Given the significance of this …

Read MoreNew research synopsis: Do citizens value fairness in the electoral competition?
Do citizens value fairness in the electoral competition? Benjamin Ferland Do citizens value fairness in the electoral competition? This is a central question that has interested scholars over the last decade. As we know, proportional electoral (PR) systems favour a more accurate translation of votes into seats while majoritarian systems have the tendency to “waste” the votes of many citizens. Inter alia, therefore, proportional representation electoral systems have the benefit of representing the voice of more citizens in legislatures and in the policy-making process. Scholars have thus assumed that citizens also share and even support this view of inclusiveness in …
