We examine a recent model, proposed by Hobson and Rogers, which generalizes the classical one by Black and Scholes for pricing derivative securities such as options and futures. We treat the numerical solution of some degenerate partial differential equations governing this financial problem and...

This paper examines the forecasting performance of GARCH’s models used with agricultural commodities data. We compare different possible sources of forecasting improvement, using various statistical distributions and models. We have chosen to confine our analysis on four indices which are the...

Estimates of daily volatility are investigated. Realized volatility can be computed from returns observed over time … intervals of different sizes. For simple statistical reasons, volatility estimators based on high-frequency returns have been … volatility bias. On the basis of a simple theoretical model for foreign exchange data, the incoherent term can be filtered away …
