An Outline of the Process of Economic Change

UNDERSTANDING economic change including everything from the rise of the Western world to the demise of the Soviet Union requires that we cast a net much broader than purely economic change because it is a result of changes (1) in the quantity and quality of human beings; (2) in the stock of human knowledge particularly as applied to the human command over nature; and (3) in the institutional framework that defines the deliberate incentive structure of a society. A complete theory of economic change would therefore integrate theories of demographic, stock of knowledge, and institutional change. We are far from having good theories of any one of these three, much less of the three together, but we are making progress. The central focus of this study, and the key to improving economic performance, is the deliberate effort of human beings to control their environment. Therefore, priority is given here to institutional change, with the consequent incentive implications for demographic and stock of knowledge changes; but there is no implication that such an approach deals adequately with the latter two. The structure we impose on our lives to reduce uncertainty is an accumulation of prescriptions and proscriptions together with the artifacts that have evolved as a part of this accumulation. The result is a complex mix of formal and informal constraints. These constraints are imbedded in language, physical artifacts, and beliefs that together define the patterns of human interaction. If our focus is narrowly on economics, then our concern is with scarcity and, hence, competition for resources. The structure of constraints we impose to order that competition shapes the way the game is played. Because various kinds of markets (political as well as economic) have different margins at which competition can be played out, the consequence of the structure we impose will be to determine whether the competitive structure induces increasing economic efficiency or stagnation. Thus well-developed property rights that encourage productivity will increase market
