Political Competition

  • David Austen-Smith
Reference work entry


This article is limited to interaction between candidates and voters and examines the cases of two-candidate competition and multiple candidate competition. It employs the spatial model of elections introduced to study single-issue politics and generalized to study multiple-issue politics in order to explain the alternatives strategically offered to voters by candidates or parties competing for electoral office.
