Split-ticket voting in German Federal elections, 1953–90: an example of sophisticated balloting?
1999
Abstract Though the German electoral system has provided the opportunity of split-ticket voting since 1953, until now there has only been mere speculation concerning the rationality of ticket-splitting. In this paper we examine the rationality thesis empirically, using data provided by the official representative electoral statistics of the Federal Republic. Modifying the Downsian notion of rational voting, rational ticket-splitting is defined in terms of coalition building and of voters' expectations of the electoral success of candidates and parties. Applying this conceptual framework, it will be shown that the combinations of first and second votes actually chosen by a majority of the Ge…
The importance of being first : Effects of candidates’ list positions in the 2003 Bavarian state election
2006
Abstract Normative theories of democracy do not pay much attention to technicalities of voting, implicitly assuming that these do not influence voting behaviour and election outcomes significantly. However, it is not clear whether this is actually the case. In this article we analyse whether one such technical detail matters for voting behaviour: the ballot position. Based on previous research in the field, we discuss ballot position effects and deduce hypotheses concerning list position effects in the 2003 Bavarian state election. In the empirical analysis, it turns out that ballot positions had a considerable influence on voting behaviour in this election, especially, the top position on …
Towards the definition of distance measures in the preference-approval structures
2022
The task of combining preference rankings and approval voting is a relevant issue in social choice theory. The preference-approval voting (PAV) analyses the preferences of a group of individuals over a set of items. The main difference with the classical approaches for preference data consists in introducing, in addition to the ranking of candidates, a further distinction; candidates are subsetted in “acceptable” and “unacceptable”, or also in “good set” and “bad set” (a way to express the approval/disapproval). This work introduces the definition of a new measure to quantify disagreement between preference-approval profiles. For each pair of alternatives, we consider the two possible disag…
Social Choice in the Real World II: Cyclical Preferences and Strategic Voting in the Finnish Presidential Elections
1997
The empirical relevance of the theoretical results of social choice theory is still unclear. The most radical thesis, put forth by William Riker, is that politics is a highly unstable process, characterized by preference cycles and strategic voting. This article - a continuation of an earlier article published in this journal - examines the Finnish presidential election in 1925, 1931, 1937 and 1982. The conclusion is that preference cycle and strategic voting have had a significant impact in the discussed cases. The relevancy of the social choice approach and its relation to historical research are discussed.
