Global volatile profile of virgin olive oils flavoured by aromatic/medicinal plants

open access: yesFood Chemistry, 2017
The global volatile profile of commercial virgin olive oils and flavoured olive oils with aromatic/medicinal plants, was established using liquid-liquid microextraction (LLME) and headspace solid-phase microextraction (HS-SPME) combined with gas ...

Oil Market Volatility and Stock Market Volatility

SSRN Electronic Journal, 2018
Abstract This paper studies the comovement between volatility of the equity market and the oil market, both for implied and realized volatilities. The wavelet methodology enables us to study this relationship on various time scales. We find that there is a strong comovement between the volatilities of the two markets. However, this comovement is time-

Oil volatility risk

Journal of Financial Economics, 2022
Abstract The option-implied oil price volatility is a strong negative predictor of economic growth beyond traditional uncertainty measures. A rise in oil volatility also predicts an increase in oil inventories and a reduction in oil consumption, in line with a propagation channel through the oil sector.

Oil Price Volatility [PDF]

open access: possibleWTO Working Papers, 2010
In recent years, our understanding of the nature of energy price shocks and their effects on the economy has evolved dramatically. Only a few years ago, the prevailing view in the literature was that at least the major crude oil prices increases were exogenous with respect to the OECD economies and that these increases were caused by oil supply ...

Geographical traceability of West Liguria extravirgin olive oils by the analysis of volatile terpenoid hydrocarbons

open access: yesJournal of Chromatography A, 2005
This study aimed at evaluating if the volatile terpenoid hydrocarbons of extravirgin olive oils from West Liguria, a North Italy region, could trace their geographical origin.

Measuring Oil Price Volatility

SSRN Electronic Journal, 2002
In this paper we try to measure oil price uncertainty. The measure of uncertainty is based on the conditional standard deviations which are derived from univariate (G)ARCH models. The measure of uncertainty we choose is the within-year high-low range of the conditional standard deviations.

Volatiles and oil quality

Journal of the American Oil Chemists' Society, 1977
Abstract and SummaryA simple, rapid, and versatile procedure for collecting and measuring volatiles from edible oils is presented. The technique involves direct sampling, can be used with all gas chromatographs having adequate sensitivity, does not require special valving, and is not limited to a specific sample size.

Volatility‐of‐volatility risk in the crude oil market

Journal of Futures Markets, 2020
AbstractThis paper examines the role of oil volatility‐of‐volatility (VOV) risk under a stochastic VOV framework. We show that oil VOV is a significant pricing factor in the cross‐sectional delta‐hedged gains constructed from oil options, and oil VOV also has predictive power for near‐term delta‐hedged option gains.

Volatility-of-Volatility Risk in the Crude Oil Market

SSRN Electronic Journal, 2019
Under the stochastic volatility-of-volatility framework, we show that oil volatility-of-volatility risk is a significant pricing factor for cross-sectional delta-hedged gains constructed from 1-month United States Oil Fund (USO) options, and is negatively priced.
