The core theory of behavior in Economics, which structures inquiry and provides a framework for empirical analysis, is largely responsible for the success of the discipline. Behavioral Economics (BE) challenges this theory, but has failed to provide a coherent alternative. Consequently the influence of BE has been limited. In what follows we argue that Evolutionary Psychology (EP), suitably adapted, can provide at least a partial foundation for BE. Its methods offer a way of generating theories of the origins of anomalous behaviors and of testing those theories.
