In this paper, we propose an easy-to-use yet comprehensive model for a system of cointegrated commodity prices. While retaining the exponential affine structure of previous approaches, our model allows for an arbitrary number of cointegration relationships. We show that the cointegration...

This study develops and estimates a stochastic volatility model of commodity prices that nests many of the previous models in the literature. The model is an affine three-factor model with one state variable driving the volatility and is maximal among all such models that are also identifiable....

In this work we perform a pricing exercise of different types of spread options; we particularly focus on European calendar and crack spread options. We present the expressions followed by the joint characteristic functions of the underlying log-prices for a panel of bivariate processes. The...

We present a new term-structure model for commodity futures prices based on Trolle and Schwartz (2009) which we extend by incorporating multiple jump processes. Our work explores the valuation of plain vanilla options on futures prices when the spot price follows a log-normal process, the...

We present a new term-structure model for commodity futures prices based on Trolle-Schwartz (2009), which we extend by incorporating seasonal stochastic volatility represented with of two different sinusoidal expressions. We obtain an analytical representation of the characteristic function of...

A strand of research documents Chile's copper dependence hence significant exposure to terms of trade shocks. Copper prices' sharp decline and forecast uncertainty since the end of the commodity super-cycle has rekindled the debate on Chile's adjustment capacity to external shocks. Following...
