A BEHAVIORAL-APPROACH OF THE DYNAMICS OF FINANCIAL-MARKETS

We introduce a non-linear dynamic deterministic multistocks multi-agen ts model. The model can be viewed as the centre of a decision support system in managing financial portfolios, that would allow the decision maker to formalize, test and analyze the impacts of strategies on a m arket. It takes into account explicitly the perceptions, strategies an d decisions of actors and their actions on a market. This approach att empts to model the decision process of interacting agents and so furni shes a tool for decision making in order to analyze the impacts of var ious strategies of actors on a market. Even in this simple model, the non-linear interactions can drive the system to sudden and unexpected effects which shows the importance of the attempt of the understanding of the dynamics.
