The energy shocks of the 1970's had significant effects on the global economy. Were they engineered by an effective cartel of OPEC members acting to share the market by controlling output and influencing market prices? If OPEC was an effective cartel sharing the market among its members, there would be a long-run relationship between each member's individual production and total OPEC output. On...

a r t i c l e i n f o JEL classification: D42 Q40 C61 Keywords: Quantity instead of price strategies OPEC Dynamic Stochastic and convex demand Uncertainty This paper analyzes the optimal strategy of a monopoly facing stochastic and dynamic demand and choosing a Cournot-type strategy, more precisely, adjusting its output. This investigation is motivated by the decisions of OPEC to adjust its out...

This study revisits the OPEC cartel hypothesis using a case study. A test is conducted to see if Venezuela has its production Granger cause its OPEC quota or whether the OPEC quota for Venezuela Granger causes Venezuelan production. The results show both occur at different times. In the short run, OPEC’s oil production quota for Venezuela Granger causes Venezuelan production. However, shortly a...

In November 2014, OPEC announced a new strategy geared towards improving its market share. Oil-market analysts interpreted this as an attempt to squeeze higher-cost producers including US shale oil out of the market. Over the next year, crude oil prices crashed, with large repercussions for the global economy. We present a simple equilibrium model that explains the fundamental market factors th...

Prior to OPEC conferences, there is usually rampant speculation about which decision concerning world oil production levels (n...

One of the objectives of OPEC is the security of demand for the crude oil exports of its members. Achieving this objective is imperative with the projected decline in OECD countries' crude oil demand among other crude oil demand shocks. This paper focuses on determining the external crude oil demand security risks of OPEC member states. In assessing these risks, this study introduces two indexe...

Oviduct epithelial cells are important for the nourishment and survival of ovulated oocytes and early embryos, and they respond to the steroid hormones estrogen and progesterone. Endocrine-disrupting polyhalogenated aromatic hydrocarbons (PHAH) are environmental toxins that act in part through the ligand-activated transcription factor arylhydrocarbon receptor (AhR; dioxin receptor), and exposur...

Carbon taxes have largely been discussed as individual country measures (even if taken simultaneously) aimed to reduce carbon emissions, slow global warning, and internalizing the externalities associated with carbon generating activities, such as power generation. There has however been little emphasis on the incentives for subgroups of countries to jointly peruse carbon taxes. Yet for large i...

The United Nations Framework Convention on Climate Change and its Kyoto Protocol require Parties to take measures to minimise the adverse effects of climate change on vulnerable countries including small island states. In negotiations the Alliance of Small Island States (AOSIS) argue that this should mean assistance for capacity building and transfer of technologies to help them adapt to a chan...

after second world war, demand for oil increased and in 1970s reached to its maximum growth. and naturally, providing this level of demand depended on much more import from opec, especially from middle eastern members. contemporaneous, in the early 1970s, some opec governments stopped granting new concessions and starting to claim equity participation in the existing concessions, with a few of ...
