Strategic Vote Choice in One-round and Two-round Elections: An Experimental Study
Résumé
The authors test a model of strategic vote choice in which the decision to support or not to support a candidate depends on the benefit associated with the election of a given candidate and the candidate’s perceived viability. They test the model with data collected in a series of experiments in which the participants voted in eight successive elections, four in one round and four in two rounds. Results show that the same model applies to both voting systems, although the impact of perceived viability is slightly weaker in two-round elections. The authors conclude that strategic considerations are almost as important in two-round as in one-round elections.
