Introducing the Brownian motion in the way of Einstein and Wiener we find the connection between a Wiener Process and the Heat Diffusion PDE.We solve the PDE analytically for some boundary conditions and then use the connection to the Wiener Process to solve more complex BVP's using Monte Carlo...

This study aims to investigate and provide further insight into the dynamics of higher moments in the estimation of optimal hedge ratios during the recent credit crisis period by applying the Gram-Charlier expansion series. Furthermore, it compares the performance of the proposed model with...

The prices of derivatives contracts can be used to estimate ‘risk-neutral' probability density functions that give an indication of the weight investors place on different future prices of their underlying assets, were they risk-neutral. In the likely case that investors are risk-averse, this...

This paper proposes that, and explains why, hedge profits and regression approach hedge ratios should be calculated using cost-of-carry-adjusted price changes. This Modified Regression Method for determining hedge ratios is denoted MRM. The paper discusses the Error-Correction Model for hedge...

We derive a general expression for the value of information to a price-taking investor in a dynamic environment and provide a framework for its estimation. We study the value of both private and public information and break it down into its instrumental and psychic parts. To illustrate, we...

We prove here a general closed-form expansion formula for forward-start options and the forward implied volatility smile in a large class of models, including the Heston stochastic volatility and time-changed exponential Levy models.This expansion applies to both small and large maturities and...

Time changes of Brownian motion impose restrictive jump structures in the motion of asset prices. Quadratic variations also depart from time changes. Joint Laplace Fourier transforms for quadratic variation and the stock are developed. They are used to study the multiple of the cap strike over...
