一类非零和投资再保险对策的跳扩散模型的逼近

Approximation of A Class of Non-Zero-Sum Investment and Reinsurance Games for Regime-Switching Jump-Diffusion Models

Trang Bui, Xiang Cheng, Zhuo Jin, George Yin

摘要:

本文研究了两个保险公司之间的一类非零和随机微分投资与再保险博弈的近似方法。比例再保险和超额损失再保险政策。通过采用马尔可夫链逼近方法和动态规划原理求解非线性积分微分Hamilton-Jacobi-Isaacs(HJI)方程,得到了求解Nash均衡的数值算法.进一步证明了逼近序列的收敛性和逼近值函数的性质。数值例子说明了算法的适用性。

英文摘要:

This work develops an approximation procedure for a class of non-zero-sum stochastic differential investment and reinsurance games between two insurance companies. Both proportional reinsurance and excess-of loss reinsurance policies are considered. We develop numerical algorithms to obtain the Nash equilibrium by adopting the Markov chain approximation methodology and applying the dynamical programming principle for the nonlinear integro-differential Hamilton-Jacobi-Isaacs (HJI) equations. Furthermore, we establish the convergence of the approximation sequences and the approximation to the value functions. Numerical examples are presented to illustrate the applicability of the algorithms.
