A Three-Way Analysis of the Relationship Between the USD Value and the Prices of Oil and Gold: a Wavelet Analysis
AIMS Energy, 6(3): 487–504. DOI: 10.3934/energy.2018.3.487 Received: 18 April 2018 Accepted: 30 May 2018 Published: 08 June 2018 http://www.aimspress.com/journal/energy Research article A three-way analysis of the relationship between the USD value and the prices of oil and gold: A wavelet analysis Basheer H. M. Altarturi1, Ahmad Alrazni Alshammari1, Buerhan Saiti2,*, and Turan Erol2 1 Institute of Islamic Banking and Finance, International Islamic University Malaysia, Kuala Lumpur, Malaysia 2 Istanbul Sabahattin Zaim University, Istanbul, Turkey * Correspondence: Email: [email protected]. Abstract: This study examines the relationships among oil prices, gold prices, and the USD real exchange rate. It adopts the wavelet approach as a nonlinear causality technique to decompose the data into various scales over time. Higher-order coherence and partial coherence were used to identify the lead-lag effect and mutual coherence function among the variables. The results show that changes in the USD exchange rate influence the prices of oil and gold negatively in the short- and medium-term. While in the long-term, the oil price has a negative impact on the value of the USD. Oil and gold are significantly linked and correlated because their prices are determined in USD. The findings of this paper have significant implications, particularly for risk management. Keywords: wavelet; partial wavelet coherence; U.S. dollar value; oil prices; gold prices 1. Introduction Examining the nexus between oil and gold is an established practice among researchers in the field of economics due to the importance of these variables. Oil is considered the primary driver of the economy. -
Geophysics 210 September 2008
Geophysics 210 September 2008 Geophysics 210 - Physics of the Earth A1: What is geophysics Geophysics: Application of physics to understand the structure and working of the Earth. Geophysics can be divided into exploration geophysics and geodynamics. Exploration geophysics is the process of imaging what is inside the Earth. Direct sampling in the Earth with drilling can only reach depths around 10 km so indirect methods are needed. Often used to describe commercial exploration, but includes investigations to depths of the mantle and core. All geophysical methods can be divided into active and passive techniques. In an active technique, it is necessary to generate a signal (e.g. in seismic studies sound waves are generated with an explosion or an earthquake). In a passive technique a naturally occurring signal is detected (e.g. the pull of gravity of a buried object). Geodynamics is the study of how the Earth works, and considers questions such as: -what drives plate motion? -what triggers earthquakes? -how is the Earth’s magnetic field generated? -how do continent-continent collisions build mountains? This field depends heavily on information derived from geophysical imaging. Advances in computer power now allow simulations of these processes in ever increasing detail and realism. A2 : Basic structure of the Earth • Radially symmetric to first order. • Crust – mainly silicate minerals, enriched in lighter elements (Na, Al) • Mantle – silicate minerals with more heavy elements (Fe and Mg) magnesium. Divided into upper and lower mantle (dashed line) • Outer core - liquid iron that convects rapidly. • Inner core – Lump of solid iron roughly the size of the moon • Crust and mantle are defined in terms of their distinct chemical compositions. -

A Comparative History of Oil and Gas Markets and Prices: Is 2020 Just an Extreme Cyclical Event Or an Acceleration of the Energy Transition?
April 2020 A Comparative History of Oil and Gas Markets and Prices: is 2020 just an extreme cyclical event or an acceleration of the energy transition? Introduction Natural gas markets have gone through an unprecedented transformation. Demand growth for this relatively clean, plentiful, versatile and now relatively cheap fuel has been increasing faster than for other fossil fuels.1 Historically a `poor relation’ of oil, gas is now taking centre stage. New markets, pricing mechanisms and benchmarks are being developed, and it is only natural to be curious about the direction these developments are taking. The oil industry has had a particularly rich and well recorded history, making it potentially useful for comparison. However, oil and gas are very different fuels and compete in different markets. Their paths of evolution will very much depend on what happens in the markets for energy sources with which they compete. Their history is rich with dominant companies, government intervention and cycles of boom and bust. A common denominator of virtually all energy industries is a tendency towards natural monopoly because they have characteristics that make such monopolies common. 2 Energy projects tend to require multibillion – often tens of billions of - investments with long gestation periods, with assets that can only be used for very specific purposes and usually, for very long-time periods. Natural monopolies are generally resolved either by new entrants breaking their integrated market structures or by government regulation. Historically, both have occurred in oil and gas markets.3 As we shall show, new entrants into the oil market in the 1960s led to increased supply at lower prices, and higher royalties, resulting in the collapse of control by the major oil companies.
