Valteori

Valteori is a field of study at the intersection of political science, economics, and philosophy that focuses on the analysis of elections, voting systems, and collective decision-making. It combines normative questions about fairness and representation with empirical and formal analyses of how votes are cast, aggregated, and translated into political outcomes.

The scope of valteori includes the design and evaluation of electoral systems (such as majoritarian, proportional representation, ranked-choice, and mixed systems), the mathematics of voting rules, and the behavior of voters and candidates. It explores how ballot design, turnout, strategic voting, and information influence election results, as well as how different systems affect accountability and policy outcomes. The field also encompasses measures of voting power, representation, and influence within electorates and legislatures.

Foundational contributions to valteori come from social choice theory and game theory. Notable results discussed in the field include Arrow’s impossibility theorem, the Gibbard–Satterthwaite theorem on strategic manipulation, and May’s theorem for binary elections. Methods frequently used include formal modeling, simulations, and empirical analysis of election data and experiments. Researchers in valteori also study issues such as districting, gerrymandering, ballot design, and reform proposals to improve legitimacy, fairness, and efficiency of democratic processes.

Critics emphasize the normative variability of prescriptions and point to the simplifications required by models of voter behavior and information. Proponents argue that systematic study of electoral rules and behavior strengthens understanding of democratic practices and policy responsiveness.
