A Relational Theory of Power Alternation
Abstract
We study the spontaneous emergence of power alternation from the need for cooperation by developing a model in which two parties repeatedly cooperate and negotiate the position of power, defined as the control right of a productive regime. Unless the party in power, “incumbent,” compromises, the party out of power, “opposition,” would withdraw from cooperation. Central to our analysis are twoimpediments: the incumbent’s hold-up problem and information asymmetry. We establish a recursive structure of the model, taking into account the endogenous roles—incumbent or opposition—the two parties play. We find that alternation of power is necessary to sustain cooperation in the long run, while within-period compromise is essential for efficiency. Two norms are inherent in efficient self-enforcing agreements, prescribing an implicit bargaining protocol and the
persistence of power. We characterize the implied dynamics of compromise, legitimacy, and power alternation and illustrate the results in context of the Whig-Tory alternation in England from 1688 to 1830.
