Complex systems in the theories of F. A. Hayek and H. A . Simon

The aim of this paper is to introduce roots of multi-agent approaches in economic theory. From the beginning, the opinion that economic system should be investigated on the basis of comprehension to its basic units was expressed by many scientists. Friedrich A. Hayek and Herbert A. Simon are two important scientists who may be designated as predecessors of multi-agent modeling. They incorporated similar principles as applied by multi-agent system approaches into their works before it was possible to deal with these principles through artificial intelligence. This paper links ideas of Hayek and Simon with multi-agent modeling, common principles and ideas are identified.
