Abstract(in English) Multi-agent models are widely used as a tool for studying social and biological systems under various kinds of objections. It is necessary to accumulate experiences in order to clarify those questions. We consider in this paper a model with positive-feedback decision rules and discuss on some useful outcomes from this model. The average price time series belong to two categories corresponding to two distinct phases in the parameter space (a, b), where a corresponds to the deflation parameter and b corresponds to an inflation parameter. Near the boundary of the two phases the price fluctuation has a statistical property very similar to the real foreign currency exchange data. We identify this observation to an evidence to show that the competitively-determined price that is normally explained as the equilibrium price is in fact corresponds to a critical region with large fluctuation. We have also considered a periodic oscillation that appears after intermittent motions with naturally-generated cooperative motion.
