WebThe pathwise derivative can be used to calculate the efficiency bound for estimators of 0, although this approach must be modified to account for the restrictions imposed by equation (4.1). We now carry out this calculation, using tangent set and projection methods. Webof derivative securities. The rst approach is based on nite di erence approximations and results in biased estimators. The other two approaches, namely the pathwise and …
