PROSPECT THEORY AND POLITICAL SCIENCE

Prospect theory is the most influential behavioral theory of choice in the social sciences. Its creators won a Nobel Prize in economics, and it is largely responsible for the booming field of behavioral economics. Although international relations theorists who study security have used prospect theory extensively, Americanists, comparativists, and political economists have shown little interest in it. The dominant explanation for political scientists' tepid response focuses on the theoretical problems with extending a theory devised in the lab to explain political decisions in the field. This essay focuses on these problems and reviews suggested solutions. It suggests that prospect theory's failure to ignite the imagination of more political scientists probably results from their aversion to behavioral assumptions and not from problems unique to prospect theory.
