Evolution and Gravitation: a Computer Simulation of a Non-Walrasian Equilibrium Model

The following notes contain a computer simulation concerning a basic nonWalrasian equilibrium system, following the Edmond Malinvaud “short side” approach, as far as the price adjustment is concerned, and the sequential Hicksian “weeks” structure with regard of the temporal characterization. Two strongly heterogeneous classes of agents will be taken into consideration: the “rich” and the “poor” and it will be shown how such sociological distinction critically influences the evolution of the framework under consideration. Finally, some methodological considerations will be added, regarding the comparison between the evolutionary and the gravitational paradigms and the evaluation of approaches belonging to rival schools of economic thought.
