We propose a novel representation of commodity spot prices in which the cost-of-carry and the spot price volatility are both driven by an arbitrary number of risk factors, nesting many existing specifications. The model exhibits unspanned stochastic volatility, provides simple closed-form...

There are two issues that are of central importance in term-structure analysis. One is the modelling and estimation of the current term structure of spot rates. The second is the modelling and estimation of the dynamics of the term structure. These two issues have been addressed independently in...

We propose a novel, fast, accurate parallel algorithm for pricing American options. We perform a thorough numerical analysis of existing methodologies and find that ours performs significantly better. The proposed method is stable, robust, and converges monotonically. We also show that the...

In this paper we study deviations from the standard textbook no-arbitrage relationship of 14 index futures from Asia, Europe, and North America between 2001 and 2012. We find strong empirical evidence that such deviations are pervasive across different countries that differ in terms of...

In this paper we provide a new multi-factor stochastic model of commodity futures prices and propose a Kalman filter estimation procedure that may be applied to a panel data with missing observations. This model may be used to implement financial engineering applications which require the...

This paper studies the ability of an N-factor Gaussian model to explain the stochastic behavior of oil futures prices when estimated using all available price information, as opposed to traditional approaches of aggregating data for a set of maturities. A Kalman filter estimation procedure that...
