We examine the volatility dynamics of NYMEX natural gas futures prices via the partially overlapping time‐series model of Smith (2005. Journal of Applied Econometrics, 20, 405–422). We show that volatility exhibits two important features: (1) volatility is greater in the winter than in the...

Despite their importance in pricing futures and other derivative contracts, seasonalvariations in mean and variance of energy prices have not been fully captured inprevious studies of energy prices. We examine the volatility dynamics of daily naturalgas futures traded on the NYMEX via the...

A recent increase in the level and volatility of regional gas prices has followed an extensive discussion on potential returns from short-term LNG trading and potentially fostering integration of geographically sparse regional gas markets. This paper examines the stochastic properties of US...

This paper contructs a stylized model of an LNG producer's decision on the level of committment to long-term supply arrangement. The model extends a conventional two-stage model of optimal hedging by accomodating two features commonly observed with LNG trading practice: (1) the forward price of...

This study compares two approaches to modeling a term structure of commodity prices. The first approach specifies the stochastic process of the underlying spot price and derives from the stipulated spot price dynamics valuation formulas of futures and other derivative contracts through no...

This study examines bias in a term-structure model of commodity prices in specifying the true stochastic dynamics of underlying spot price. The bias is quantified by comparing the model estimated by the conventional method of estimating all model parameters simultaneously with a panel of futures...

Sprint finishes in professional cycling are fast, furious, and dangerous. A “red flag rule†(RFR) seeks to moderate the chaos of these finishes, but may induce moral hazard by removing the time penalty associated with crashing. To test for moral hazard, the authors use a 2005 rule...

The availability of immigrant farm-workers from Mexico is a critical factor affecting the fresh fruit and vegetable sector in the United States. This paper uses a retrospective panel data set from rural Mexico to examine the impact of the North American Free Trade Agreement and the Immigration...
