Rational choice institutionalism
Rational Choice Institutionalism (RCI) is a theoretical approach to the study of institutions arguing that actors use institutions to maximize their utility. However, actors face rule-based constraints provided by the institutional environment which influence their behaviour. Rational Choice Institutionalism arose initially from the study of congressional behaviour in the U.S. in the late 1970s. It employs analytical tools borrowed from neo-classical economics to explain how institutions are created, the behaviour of political actors within it, and the outcome of strategic interaction.
