Abstract
There is a close but largely unexplored connection between law and economics and cognitive psychology. Law and economics applies economic models, modes of analysis, and argument to legal problems. Economic theory can be applied to legal problems for predictive, explanatory, or evaluative purposes. In explaining or assessing human action, economic theory presupposes a largely unarticulated account of rational, intentional action. Philosophers typically analyze intentional action in terms ofdesiresandbeliefs. I intend to perform some action because Ibelievethat it will (is likely to) produce an outcome that Idesire. This standard “belief-desire” model of action invokes what philosophers of psychology and action theorists aptly refer to as a “folk psychology.”
