We derive Nash equilibrium candidate strategies in a double-member district election when voters have nonseparable preferences for candidates in a single-dimensional policy space. When candidates are elected simultaneously, nonseparable voter preferences create multiple equilibria, including...

Is the rational-choice paradigm more than a mere tautology when applied to the study of voting or can it generate refutable propositions that cannot be deduced or inferred from other approaches? This is the question we address empirically in the context of three-candidate presidential elections....

This paper presents a formal game-theoretic model to explain the simultaneity problem that has made it difficult to obtain unbiased estimates of the effects of both incumbent and challenger spending in U.S. House elections. The model predicts a particular form of correlation between the expected...
