Contingent prize allocation and pivotal voting

Parties can elitcit widespread electoral support by making the distribution of prizes or rewards to groups of voters contingent upon electoral support. In addition to altering which party wins, a voter's choice also influences the distribution of prizes. This latter factor, referred to in this article as prize pivotalness, tends to be the dominant influence in vote choice. The desire to win prizes can induce voters to coalesce into a highly supportive group, even if they dislike the party's policies. Characterizing voting equilibria in this framework explains the rationale for the support of patronage parties, variance in voter turnout and the endogenous political polarization of groups in both established and new democracies.
