摘要
讨论Vasicek短期利率模型下,风险资产的价格过程服从跳-扩散过程的欧式未定权益定价问题,利用鞅方法得到了欧式看涨期权和看跌期权定价公式及平价关系,最后给出了基于风险资产支付连续红利收益的欧式期权定价公式.
This paper discusses the problem of contingent claims valuation when the underlying asset price is a jump-diffusion process under stochastic interest rates. Using martingale method, pricing formula of European contingent claims is derived and put-call parity is analyzed. Pricing formula of European option is also given when risk asset pays continuous dividends.
