摘要 研究了离散时间模型的幂效用函数无差别定价问题.利用鞅方法证明了完全市场的幂效用函数无差别定价为无套利定价,讨论了不完全市场中幂效用函数无差别定价计算的关键问题,并得到了单阶段三叉树模型的幂效用函数的无差别定价满足的方程. This paper deals with the indifference pricing of power utility function under discrete-time model.It is shown that the indifference pricing is free-arbitrage pricing by the martingale approach.The main thing about the power utility function indifference pricing is considered in the incomplete market,and the equation satisfying the power utility function indifference pricing is obtained under single stage trinomial tree model.
