Do events in the natural gas market cause repercussions in the crude oil market? This paper studies linkages between the two markets using high-frequency, intraday oil and gas futures prices. By analyzing the effect of weekly oil and gas inventory announcements on price volatility, we show a...

This paper studies the target pricing zone (TPZ) hypothesis for crude oil by examining price clustering in the dollar digit. It is hypothesized that price clustering occurs within an established TPZ if OPEC is able to defend the upper and lower bounds through output changes. The results show...

Ethanol crush spreads are used to model the value of a facility which produces ethanol from corn. A real option analysis is used to investigate the effects of model parameters on the related managerial decisions of (i) how to operate the facility through optimal switching from idled to...

In this analysis we more accurately capture the cointegrating relationship between natural gas and crude oil prices by endogenously incorporating shifts in the cointegrating vector into the estimation of the cointegrating equation. Specifically, we allow the cointegrating equation to switch...

The effects war and terrorism have on the covariance between oil prices and the indices of four major stock markets – the American S&P500, the European DAX, CAC40 and FTSE100 – using non-linear BEKK–GARCH type models are investigated. The findings indicate that the covariance between stock...

In this article, we test for the existence of daily seasonality in returns and volatilities of crude oil. Using a dummy-augmented GARCH specification for the period from May 1987 to October 2013, our key findings are as follows: (i) Volatilities on Mondays are significantly higher than on all...
