in this paper, a novel hybrid model based on neural network and game theory is proposed to support the analyzers in oil market. in this model, first the neural network is utilized to learn the oil prices associated with opec production level and usa imports level. then the learned neural network is applied by a game model. finally the nash equilibrium points of the game present the optimum deci...

from OPEC-caused price changes.) In addition, we believe that use of regulated prices is inconsistent with the spirit of a study purporting to demonstrate the advantages of increased competition. Our second alternative question modifies the meaning of an optimally configured capital stock. We call it the dynamic optimization (DO)

This study further develops a party to party gas price bargaining model (expanded in a research paper by Okugu, 2002) by using proxies of prices of these replacement fuels in OPEC spot oil prices and Henry Hub (HH) spot gas prices. The study finds a significant relationship between the variables. When optimally lagged data are analysed in a vector autoregressive model, a significant longer-term...

This paper is mainly concerned with the classical KKT reformulation and the primal KKT reformulation (also known as an optimization problem with generalized equation constraint (OPEC)) of the optimistic bilevel optimization problem. A generalization of the MFCQ to an optimization problem with operator constraint is applied to each of these reformulations; hence leading to new constraint qualifi...

the organization of the petroleum exporting countries (opec) has a key role in making universal political and economic decisions regarding petroleum. therefore, it seems highly important to assess the opec member’s degree of concentration and its monopoly.  this research, aims to assess and classify the concentration of petroleum export in the opec countries during the 1997-2011 period by the h...

Between January 2017 and March 2020 a coalition of oil producers led by OPEC Russia (known as OPEC+) cut production in an attempt to raise the price crude oil. In corona virus shock collapse this coalition, members did not agree on keeping market tight face large negative demand shock. Yet, was OPEC+ actually effective sustaining oil? early when strategy place, inventories fell substantially re...

This paper contributes to the discussion of role that terrorism plays in oil production and prices literature by studying dynamics terrorist attacks OPEC. To this purpose, we use techniques based on fractional integration, cointegration VAR (FCVAR) wavelet analysis. Monthly data related OPEC production, basket crude from January 1970 December 2018 are used. The results, using integration techni...

This study estimates three hypotheses of OPEC behavior: market-sharing, target revenue and competitive model for the period 1980 to 2000 for all OPEC courtiers except Iraq. To examine co-integration relation for oil production, we use ADF test in OLS estimation. Also we use ARDL approach to examine these hypotheses and the long run relationship of them. Results indicate none of three hypotheses...
