| 摘 要： | 考虑市场存在交易费率的跳扩散欧式期权的定价问题.由于交易费的存在使得传统的对冲方法不适用,我们将该问题转化为两元的随机控制问题.证明了带固定比例交易费率的跳扩散欧式期权的价格是对应的积分微分不等方程的约束粘性解,并通过马尔科夫链对变分问题进行离散,证明了在粘性意义下离散方法的收敛性.最后给出了数值结果. |

| Abstract: | In this paper,the pricing problem of jump-diffusion European options is considered in a market with transaction costs.As for the trading cost the traditional hedging method can not be applied,we transform the problem into the stochastic control problem with two control variables.We show that the pricing of jump-diffusion European options with fixed ratio transaction cost are the constrained viscosity solution of the corresponding nonlinear integraldifferential inequation.The variational problem is dispersed by the Markov chain.We also show the convergence of discrete schemes in the viscosity sense.In final,the numerical results are given. |
| Keywords: | European option transaction cost jump-diffusion Markov chain integraldifferential inequation constrained viscosity solution stochastic control |
