We propose a way to compute the hedging Delta using the Malliavin weight method. Our approach, which we name the l-method, generally outperforms the standard Monte Carlo finite difference method, especially for discontinuous payoffs. Furthermore, our approach is nonparametric, as we only assume...

When analysing the volatility related to high frequency financial data, mostly non-parametric approaches based on realised or bipower variation are applied. This article instead starts from a continuous time diffusion model and derives a parametric analog at high frequency for it, allowing...

average treatment effect of interest will typically fail. While the form of this measurement error varies across applications …, in many cases the measurement error structure is heterogeneous across different groups of observations. We develop a … novel measurement error correction procedure capable of addressing heterogeneous mismeasurement structures by leveraging …
