Nomination Processes and Policy Outcomes

Abstract

We model and compare three different processes by which political parties nominate candidates for a general election: nominations by party leaders, nominations by a vote of party members, and nominations by a spending competition among potential candidates. We show that in equilibrium, non-median outcomes can result when two parties compete using nominations via any of these processes. We also show that more extreme outcomes can emerge from spending competition than from nominations by votes or by party leaders. When voters (and potential nominees) are free to switch political parties, then median outcomes ensue when nominations are decided by a vote but not when nominations are decided by spending competition.
