In this paper, we study the oil price formation for the purpose of understanding price reactions of OPEC member countries to changes in the exchange rate of the US dollar and prices of other members in the short run. The results suggested that there is a partial impact of exchange rates...

This article examines the real convergence hypothesis in OPEC countries (Algeria, Angola, Ecuador, Gabon, Indonesia, Iran, Iraq, Kuwait, Libya, Nigeria, Qatar, Saudi Arabia, United Arab Emirates and Venezuela) using time series techniques and allowing for structural breaks. The main results show...

Global oil markets were roiled by sharp price swings in 2008, and economists are still divided over the reasons for the unusual volatility. Those emphasizing fundamentals point to inelastic supply and demand curves, others view the phenomenon mostly as a result of financial investors flocking...

This paper investigates the causes of extreme fluctuations in commodity prices from 1990 to 2010. Analyzing two very distinct commodities-crude oil and fine wine, we find that macroeconomic factors are the main determinants of commodity prices. Although supply constraints have the expected...

Analyzing macroeconomic impacts of oil price changes requires first to investigate different sources of these changes and their distinct effects. Kilian (2009) analyzes the effects of an oil supply shock, an aggregate demand shock, and a precautionary oil demand shock. The paper's aim is to...

This study seeks to explain why crude oil prices fluctuate, the main cause being the quota regime, which characterises the OPEC agreements. Given that the Saudi oil supply is inelastic in the short term, a shock in the oil market is accommodated by an immediate price change. In contrast, a...

This paper studies the effects of demand and supply shocks in the global crude oil market on several measures of countries' external balance, including the oil and non-oil trade balances, the current account, and changes in net foreign assets (NFA) during 1975-2004. We explicitly take a global...

Unter der Annahme, daß das reale Bruttosozialprodukt in den OECD-Ländern 1990 um 2,75% und 1991 um 3% wächst, und der Dollarkurs im Prognosezeitraum weitgehend unverändert bleibt, wird sich das Preisniveau auf den internationalen Rohstoffmärkten insgesamt (d.h. einschl. Energieträger) 1990...
