Semi-nonparametric estimation of the call-option price surface under strike and time-to-expiry no-arbitrage constraints
执行价与到期时间无套利约束下的看涨期权价格曲面半非参数估计
We suggest a semi-nonparametric estimator for the call-option price surface. The estimator is a bivariate tensor-product B-spline. To enforce no-arbitrage constraints across strikes and expiry dates, we establish sufficient no-arbitrage conditions on the control net of the B-spline surface. The conditions are linear and therefore allow for an implementation of the estimator by means of standard quadratic programming techniques. The consistency of the estimator is proved. By…
