| Sintesi≠ | Selectorate theory, developed by Bruce Bueno de Mesquita, Alastair Smith, Randolph Siverson, and James Morrow in The Logic of Political Survival (2003), explains policy and foreign-policy behavior as a by-product of leaders' overriding goal: staying in power. Every leader depends on a winning coalition (W) drawn from a larger selectorate (S) of those with a say in choosing leaders. The relative size of W and S determines whether a leader buys loyalty with broad public goods or narrow private rewards — which in turn shapes growth, war, peace, and the survival of regimes. | Polity score analysis uses the Polity dataset to measure and compare the regime characteristics of states on a continuum from full autocracy to full democracy. Maintained by the Center for Systemic Peace (Marshall and Gurr), Polity codes institutional features — how chief executives are recruited, the constraints on their authority, and the openness of political competition — into separate democracy and autocracy indices that combine into a single polity score from −10 to +10. It is one of the most widely used measures of regime type in comparative politics and international relations. |
