پویایی قیمت بازارهای مالی با استفاده از معادله دیفرانسیل تصادفی برای یک دوتایی بالقوه

We have used the Itô’s stochastic differential equation for the double well with additive white noise as a mathematical model for price dynamics of the financial market. We have presented a model which allows us to test within the same framework the comparative explanatory power of rational agents versus irrational agents, with respect to the facts of financial markets. We have obtained the mean price in terms of the β parameter that represents the force of the randomness term of the model.
