The uses of economics are many, as are also the methodologies by which its various purposes can be defended or elucidated. In this paper I shall confine my attention, however, to but one of its many aims—the predictive intent that constitutes a distinguishing characteristic of so much economic work. Lest I be accused of claiming that prediction is an integral part of all economics, let me explicitly point out that the discipline has taxonomic, structural, purely formal, normative, and still other aspects, none of which involves prediction, and all of which have their useful roles to play. Nonetheless, I do not think that most economists would disagree with my contention that a predictive purpose lies at the heart of much of economic science today, in particular when that science is used on behalf of policy.
