Audience cost in the context of Rational Choice (international relations)

Rational choice (also termed rationalism) is a prominent framework in international relations scholarship. Rational choice is not a substantive theory of international politics, but rather a methodological approach that focuses on certain types of social explanation for phenomena. In that sense, it is similar to constructivism, and differs from liberalism and realism, which are substantive theories of world politics. Rationalist analyses have been used to substantiate realist theories, as well as liberal theories of international relations.

Rational choice research tends to explain conditions that bring about outcomes or patterns of behavior if relevant actors behave rationally. Key concepts in rational choice research in international relations include incomplete information, credibility, signaling, transaction costs, trust, and audience costs.

James D. Fearon (born c. 1963) is the Theodore and Francis Geballe Professor of Political Science at Stanford University; he is known for his work on the theory of civil wars, international bargaining, war's inefficiency puzzle, audience costs, and ethnic constructivism. According to a 2011 survey of International Relations scholars, Fearon is among the most influential International Relations scholars of the last twenty years. His 1995 article "Rationalist Explanations for War" is the most assigned journal article in International Relations graduate training at U.S. universities.
