Selectorate Theory

Core concepts

The theory assumes that every leader's first goal is to stay in power. The selectorate (S) is the set of people who can influence the choice of leader, and the winning coalition (W) is the subset whose support the leader needs to retain power. Bueno de Mesquita et al. (2003) argued that when W is small, it is efficient for leaders to buy loyalty by distributing private goods to a few insiders, whereas when W is large it is efficient to provide public goods that benefit everyone. The smaller the ratio W/S, the greater the risk that coalition members would lose their place under a new leader, making them more loyal to the incumbent, a pattern called the loyalty norm.

Implications for policy and international politics

The framework predicts that democracies with large winning coalitions provide more public goods such as education, health and rule of law, while corruption and rent seeking are common where coalitions are small. Lake and Baum (2001) likewise reported that democracy increases public service provision. Bueno de Mesquita et al. (1999) used the logic to explain the democratic peace, arguing that leaders with large coalitions, whose survival is threatened by defeat, select wars they can win and devote more resources to them. Bueno de Mesquita and Smith (2010, 2011) also analyzed how non-tax revenues such as natural resources and foreign aid affect leader survival and institutional change.

Empirical assessment and critiques

Clarke and Stone (2008) argued that the original analysis overstated the effect of W by failing to control for other elements of democracy, and Morrow et al. (2008) responded with retests showing that an independent effect of W remains. Kennedy (2009) noted that the measure of W overlaps heavily with indicators of regime type. Gallagher and Hanson (2015) judged the theory limited in explaining variation within authoritarian regimes, and Svolik (2012) and Geddes (1999) emphasized elite power sharing and differences across regime types. Alongside Olson's (1993) stationary bandit argument, the theory is a leading framework for analyzing political institutions from a public choice perspective.

FAQ

What is selectorate theory in simple terms?

Where a leader only needs to satisfy a small circle of insiders, the leader hands them perks; where broad support is needed, the leader adopts policies that help everyone.

Is the theory empirically supported?

Links between regime type and public goods provision appear in many studies, but critiques and rebuttals continue over how to measure the winning coalition and separate it from other features of democracy.
