Complexity of voting manipulation is a prominent research topic in computational social choice. The voting manipulation literature usually assumes that the manipulator is only concerned with improving the outcome of the election from her perspective. However, in practice, the manipulator may also be reluctant to lie, i.e., she may have a preference for submitting a vote that does not deviate to...

Arizona State University! !! Introduction! On October 19th, 2015, Canadian citizens will head to the polls in their country’s 42nd general election. The vote offers the choice between the existing right wing government (Stephen Harper’s Conservatives), three largely left-of-center alternatives (the New Democrats, Liberals, and Greens), a regional party (the Bloc Québécois), and several independ...

This study draws from agenda-setting and issue priming theories to develop hypotheses about how state-level ballot propositions may affect presidential elections. We propose that ballot measures prime voters to evaluate candidates in terms of policy questions placed on their state ballot. We test if concerns about gay marriage in 2004 had greater salience for voters in states where proposals to...

Electoral equilibria depend upon candidates’ motivations. Maximization of expected vote share may not lead to the same behavior as maximization of the probability of winning the election. Accordingly, it is desirable to understand when electoral equilibria are insensitive to the choice of candidate motivations. This paper examines sufficient conditions for local equilibrium equivalence between ...

To improve weak classifiers bagging and boosting could be used. These techniques are based on combining classifiers. Usually, a simple majority vote or a weighted majority vote are used as combining rules in bagging and boosting. However, other combining rules such as mean, product and average are possible. In this paper, we study bagging and boosting in Linear Discriminant Analysis (LDA) and t...

This research examines the applicability of cognitive dissonance theory to explain a judge’s decision to author or join a separate opinion. I propose that, following a counter-attitudinal vote, a judge will endeavor to reduce the aversive consequences of being viewed as an inconsistent decision maker by justifying his or her attitudinally incongruent vote choice to the public in a separate opin...

An expanding literature indicates that in multiparty systems with coalition governments, citizens consider the post-electoral bargaining process among parties when casting their vote. Yet, we know surprisingly little about the nature of voters' coalition preferences. This paper uses data from the Austrian National Election Study to examine the determinants as well as the independence of prefere...

We investigate the relationship between controversial roll call votes and support for Democratic incumbents in the 2010 midterm elections. Consistent with previous analyses, we find that supporters of health care reform paid a significant price at the polls. We go beyond these analyses by identifying a mechanism for this apparent effect: constituents perceived incumbents who supported health ca...

So-called online Voting Advice Applications (VAAs) have become very popular all over Europe. Millions of voters are using them as an assistance to make up their minds for which party they should vote. Despite this popularity there are only very few studies about the impact of these tools on individual electoral choice. On the basis of the Swiss VAA smartvote we present some first findings about...
