报告摘要:
We construct a heterogeneous asset pricing model with varying investor sentiment. Based on the analysis of the dynamics of the model, we find that the stability of fundamental equilibrium point is determined by the balance of the activities of both types of traders. The overreaction of either type of the traders leads to price fluctuation in long time period. We also find that the intensity of chartist’s sentiment does not affect the stability of the fundamental equilibrium point, but it does influence the type of the bifurcations. The simulation on the corresponding stochastic model is successful to replicate some of the stylized facts in real financial market, including volatility clustering, skewness, excess kurtosis and long memory.
