Abstract
Economists have shown an increasing interest in systems theory and simulation. The recent reviews by Anderson and LaDue and Vincent indicate the literature is repleat with models of business and farm firms developed by researchers from several disciplines. A smaller but no less sophisticated group of models is focused on simulated physical or biological processes. An even smaller segment of the literature deals with economic applications of models which simulate physical and biological phenomena. Economists have become interested in models simulating physical and biological phenomena because of their experimental value. When a satisfactory approximation of reality can be created within the context of the model, experiments can then be conducted to determine the effects of changes in exogeneous factors on outcomes predicted by the model.
