FX risk-neutral valuation relationships for the SU jump-diffusion family
推导了外汇期权的无偏好定价公式,该公式与一般均衡代表性代理人经济一致,能生成对称和不对称的波动率微笑,解决了Black和Garman-Kohlhagen模型的定价偏差。
This paper derives preference-free pricing formulae for foreign exchange options, which are consistent with a general equilibrium representative agent economy. These risk-neutral valuation relationships (RNVR's) are obtained for the SU jump-diffusion family. Call and put options are particular cases of our general model. These option pricing formulae nest Merton's (1976) jump-diffusion equations. Our option valuation formulae are able to generate symmetric and asymmetric volatility smiles and skews with similar shapes to those observed in the foreign exchange options market, and they solve several pricing biases of Black (1976) and Garman and Kohlhagen (1983) models.
