保险市场中基于不同理性的三寡头垄断动态博弈模型研究
首发时间:2012-12-04
摘要:本文在国内外学者研究工作的基础上,我们考虑三寡头垄断的保险市场动态价格博弈模型。在模型中,一个寡头采取自适应决策,一个寡头采取延迟有限理性决策,还有一个寡头采取有限理性决策,由此建立三寡头价格博弈微分方程模型,且该系统有唯一的Nash均衡点,并对该系统的稳定性和Hopf分岔的存在性进行研究。数值模拟结果证实了上述理论的准确性,并且更直观地展示了系统的动态行为。保险公司在考虑延迟的价格博弈的过程中,必须控制好延迟参数的值,并适当地降低自身价格调整速度,以使系统尽快稳定到平衡状态。

The research of three oligarchs'dynamic game model in insurance market based on different rational
Abstract:Based on the research of the scholars at home and aboard, we established and have an analysis on three oligarchs' dynamic game model in insurance market. In this model, first oligarch takes the strategy of self-adaption, while the second one takes the strategy of limited bounded rationality with time delay, and the third one adapt the limited bounded rationality decision, then we establish the three oligarchs' dynamic game model according to these. From the calculation, we know that the system has only one Nash equilibrium point, and then we have the research on the stability and existence of the Hopf bifurcation of the system. The numerical simulation verifies the correction of above theory, and shows the system's dynamic behavior intuitively. In the process of insurance corporation's price game with the consideration of time delay, they must have a good control on the delay parameter, and reduce the price adjust speed suitably, so as the system could stay in a stable station as soon as possible.
