Why do individuals vote for minor parties with no realistic chance of winning? A game theory approach

Abstract

This Work Project explores voting behaviour, focusing on why voters support parties they know will not win, by applying a game theory framework complemented with a survey analysis. By combining game-theoretic analysis, which illustrates the trade-offs voters face under varying scenarios, with survey results and analysis, exploring real voter motivations, this research examines how partisanship, electoral systems and voter expectations shape decision-making. The study delves into strategic and ideological voting patterns, considering the influence of protest voting and the role of uncertainty in voter choices.
