The Hopf Bifurcation of Stochastic Dynamical Price Model

摘要：

In this paper, first, nonlinear stochastic dynamical price model which subjected to Gaussian white noise excitation Is proposed based on deterministic model. Then, we get the stochastic differential equation of system by using the stochastic averaging method. Based on the averaged differential equation, stochastic Hopf bifurcation of the price system has been studied by using the theory of singular points of diffusion processes. Finally, the economical meanings of the bifurcation phenomena have been given.
