PRICING KERNEL ESTIMATION: A LOCAL ESTIMATING EQUATION APPROACH
定价核估计:局部估计方程方法
This paper investigates a general semiparametric stochastic discount factor formulation that avoids functional form misspecification. A new semiparametric estimation procedure is proposed which combines orthogonality conditions and local linear fitting to give a semiparametric generalized estimating equation approach. Asymptotic properties of the estimators are established and we explore the empirical usefulness of the proposed approach to value-weighted stock returns.
