【本期主题】Stochastic equilibria of an asset pricing model with heterogeneous beliefs and random dividends
In this paper, we investigatedynamical properties of a heterogeneous agent model with random dividends andfurther study the relationship between dynamical properties of the random modeland those of the corresponding deterministic skeleton, which is obtained bysetting the random dividends as their constant mean value. Based on our recent mathematicalresults, we prove the existence and stability of random fixed points as the perturbationintensity of random dividends is sufficiently small. Furthermore, we prove thatthe random fixed points converge almost surely to the corresponding fixedpoints of the deterministic skeleton as the perturbation intensity tends tozero. Moreover, simulations suggest similar behaviors in the case of morecomplicated attractors. Therefore, the corresponding deterministic skeleton isa good approximation of the random model with sufficiently small randomperturbations of dividends. Given that dividends in real markets are generallyvery low, it is reasonable and significant to some extent to study the effectsof heterogeneous agents’ behaviors on price fluctuations by the correspondingdeterministic skeleton of the random model.
