Financial Markets Dynamics
Résumé
The volatility of stock prices is di cult to explain within the con nes of rational pric- ing models. Changes in prices have become permanent at both the individual and the aggregate level. Therefore, when keeping the hypothesis of a rational behavior of agents, we need to give a new explanation to the price settlement of nancial assets at any mo- ment of time. In a model based on an original mathematical framework, we introduce persistent time- varying prices resulting from rational strategic interactions of agents. We demonstrate that in a close to equilibrium market, actual prices give the best approximation of funda- mental value; We also explain why, in some circumstances, rational behavior may lead to the development of a bubble or the surge of a nancial crisis.
