Selectorate theory

The selectorate theory is a theory of government that studies the interactive relationships between political survival strategies and economic realities. It is first detailed in The Logic of Political Survival, authored by Bruce Bueno de Mesquita of New York University (NYU), Alastair Smith of NYU, Randolph M. Siverson of UC Davis, and James D. Morrow of the University of Michigan. In subsequent years the authors, especially Bueno de Mesquita and Smith, have extended the selectorate theory in various other policy areas through subsequent academic publishings and books. The theory is applicable to all types of organizations with leadership, including (among others) private corporations and non-state actors.

The theory is known for its use of continuous variables to classify regimes by describing the ratios of coalitions within the total population. Regimes are classified on a spectrum of coalition size, as opposed to conventional, categorical labels (for example, the authors define conventional democracy as a large coalition regime and autocracy as a small coalition regime). The theory has been applied to a large range of topics including foreign aid, the choice of tax rates by incumbent political leaders, as well as medieval European history.
