Institutional Incentives for Strategic Voting:

Looking more closely at the way people form expectations about the possible outcome of the election in their electoral district I will provide evidence for the first time that strategic voting can be observed and predicted even in PR systems with large districts magnitudes, such as in Portugal. Employing district-level data from 1975-2002 I estimate that a party, who is expected to win no seat, will be strategically deserted on average by about 3 per cent of the voters. This number does systematically vary with the district magnitude of each district and is largest (> 4 per cent) in Portugal�s smallest electoral districts (e.g., Beja and Ãvora). Nevertheless even in Portugal�s largest electoral district, Lisbon, strategic voting can be observed to have a systematic impact on parties vote shares.

Electoral System Change in Belgium 2003: Party Strategies and Voter Responses

The paper addresses two points: First, what is the effect of changes to the electoral system in Belgium and second, how do voters respond to the new electoral rules? If seat-maximization is the key link then this would lead to the prediction that parties that supported the change of the electoral system particularly the parties of the incumbent governing coalition (before the change took place for the 2003 election), should expect to fare better under the new rules than the old rules that translate votes into seats. The mechanical effects of the new electoral rules for 2003 when applied to the number of votes cast in 1995 and 1999 do have a small effect in the direction predicted by the theory. The governing parties together, particular the rancophone ones, can expect to fare better under the new rules than under the old rules. Regarding the second question, the number of Strategic Voters in a given district is typically predicted by the district magnitude, i.e. the number of seats that are awarded at the primary electoral district level. Contrary to previous studies there is strong evidence of strategic voting particularly within the small Belgian districts. This analysis further demonstrates that even the new incentives to cast a strategic vote through the need for every party to overcome 5% of the district vote share before gaining representation has already a systematic impact on the decision-making process of Belgium voters.

Comparative Politics of Strategic Voting: A Hierarchy of Electoral Systems

What is the impact of electoral rules on the way people make decisions in the voting booth? Traditionally the literature about electoral systems argues that the size of the district magnitude determines the amount of strategic voting. I argue, however, that different electoral systems provide incentives that potentially undermine or facilitate the Duvergerian logic in practice. Contrary to the literature the results indicate that the impact of the district magnitude on the frequency of strategic voting in a given polity is conditional on the type of seat allocation system that defines how votes get translated into parliamentary seats.

Polls, Coalition Signals, and Strategic Voting: An Experimental Investigation of Perceptions and Effects

The paper investigates how poll information and coalition signals affect strategic voting, defined as casting a vote for a party other than the most preferred party to better influence the election outcome. In particular if the outcome of an election is perceived to be close, voters in multi-party systems with proportional representation and coalition governments should have an incentive to cast a vote for the party that best influences the formation of the next government. The study focuses in particular on voters’ attention to and perception of polls and coalition signals sent by parties before elections. The study used an innovative design that embedded a laboratory experiment in two real election campaigns, allowing the manipulation of poll results and coalition signals in a realistic environment. The findings suggest that political sophistication plays a crucial role for the accurate perception of polls and strategic voting. Coalition signals are found to have a surprisingly strong effect on (apparently) strategic voting.

Tickel-splitting and strategic voting under mixed electoral rules : evidence from Germany

There is more to strategic voting than simply avoiding to waste someone�s vote if one is liberated from the corset of studying voting behavior in plurality systems. Mixed electoral systems provide different voters with various incentives to cast a strategic vote. They do not only determine the degree of strategic voting, but also the kind of strategies voters employ. Strategic voters employ either a wasted-vote or a coalition insurance strategy but cast their vote not automatically for large parties as the current literature suggest. This has important implication for the consolidation of party systems. Moreover, even when facing the same institutional incentives, voters vary in their proclivity to vote strategically

Institutional incentives for strategic voting : the case of Portugal

Looking more closely at the way people form expectations about the possible outcome of the election in their electoral district I will provide evidence for the first time that strategic voting can be observed and predicted even in PR systems with large districts magnitudes, such as in Portugal. Employing district-level data from 1975-2002 I estimate that a party, who is expected to win no seat, will be strategically deserted on average by about 3 per cent of the voters. This number does systematically vary with the district magnitude of each district and is largest (> 4 per cent) in Portugal's smallest electoral districts (e.g., Beja and Évora). Nevertheless even in Portugal's largest electoral district, Lisbon, strategic voting can be observed to have a systematic impact on parties vote shares

Strategic Voting in Multiparty Systems: A Group Experiment

The paper tests the theory of strategic voting for multiparty systems with proportional representation and coalition governments at the micro-level. The study focuses in particular on the question whether participation in repeated elections allows voters to learn from experience and enables them to optimize their decision behavior. An economic group experiment with decision scenarios of varying degrees of difficulty was used to test decision making at both the individual and group level. The results suggest that a majority of voters were able to pursue successful decision strategies and that the difficulty of the decision scenarios affected the voting performance of the participants as expected. However, a learning effect is not supported by the data.
