In this paper we examine whether the real prices of eleven natural resource commodities exhibit stochastic or deterministic trends. A common methodological feature in the relevant empirical literature, most of which published in the Journal of Environmental Economics and Management, has been so...

The bulk of the literature investigating persistence properties of non-renewable resource prices series has focused on application of unit root tests. This paper contributes to the debate, applying a methodology which allows (1) robust detection of the presence and (if so) the number of changes,...

This paper investigates the trend in the monthly real price of oil between 1990 and 2008 with a generalized autoregressive conditional heteroskedasticity (GARCH) model. Trend and volatility are estimated jointly with the maximum likelihood estimation. There is long persistence in the variance of...

This paper considers the question of whether changes in persistence have occurred during the long-run evolution of U.S. prices of the non-renewable energy resources crude oil, natural gas and bituminous coal. Our main contribution is to allow for a structural break when testing for a break in...

The purpose of this research is to determine whether a relationship exists between the sales of small businesses when a large economic event occurs in the area. The sales examined were those of a small auto parts store located within in the Bakken Shale Formation during the rise and fall of the...

Sentiment is shown to influence both West Texas Intermediate (WTI) and Brent futures prices during the period 2002-2013. This is demonstrated while controlling for stock indices, exchange rates, financial costs, inventory and supply levels as well as OPEC activity. Sentiment indices are...

In this paper we examine the time series properties of nine non-renewable resources. In particular we are concerned with understanding the relationship between the number of structural breaks in the data and the nature of the resource price path, i.e. is it stationary or a random walk. To...
