Impact of Ethanol Production on U.S. and Regional Gasoline Prices and On the Profitability of U.S. Oil Refinery Industry

Du, Xiaodong; Hayes, Dermot J. - Agricultural and Applied Economics Association - AAEA - 2008

Using pooled regional time-series data and panel data estimation, we quantify the impact of monthly ethanol production on monthly retail regular gasoline prices. This analysis suggests that the growth in ethanol production has caused retail gasoline prices to be $0.29 to $0.40 per gallon lower...

Analysis of crack growth with robust, distribution-free estimators and tests for non-stationary autoregressive processes

Kustosz, Christoph; Müller, Christine - In: Statistical Papers 55 (2014) 1, pp. 125-140

This article investigates the application of depth estimators to crack growth models in construction engineering. Many … crack growth models are based on the Paris–Erdogan equation which describes crack growth by a deterministic differential … equation. By introducing a stochastic error term, crack growth can be modeled by a non-stationary autoregressive process with …

Are Product Spreads Useful for Forecasting? An Empirical Evaluation of the Verleger Hypothesis

Baumeister, Christiane; Kilian, Lutz; Zhou, Xiaoqing - C.E.P.R. Discussion Papers - 2013

Notwithstanding a resurgence in research on out-of-sample forecasts of the price of oil in recent years, there is one important approach to forecasting the real price of oil which has not been studied systematically to date. This approach is based on the premise that demand for crude oil derives...

Morphological similarity of road networks and cracks

Ohnishi, Teruaki; Okada, Osami; Shirakata, Hirofumi - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 18, pp. 4127-4133

An investigation was made regarding to what extent road network patterns are reproduced by a crack model from a … viewpoint that they seem to resemble crack patterns in morphology. A desiccation model using double-layered cellular meshes was … introduction of singularities in points and in lines. The model can generally reproduce the real crack patterns and the road …

The (de)merits of minimum-variance hedging: Application to the crack spread

Alexander, Carol; Prokopczuk, Marcel; Sumawong, Anannit - In: Energy Economics 36 (2013) C, pp. 698-707

models for estimating hedge ratios of crude oil, gasoline and heating oil crack spreads. Given the great variability and …. Therefore we encourage hedgers to use a naïve hedging strategy on the crack spread bundles now offered by the exchange; this …
