The main and effective buyers and sellers of crude oil in global market are OPEC and OECD organizations that they are trying to change the prices in their favor. This paper investigated a game theory model for the two organizations which how to behave against each other in oil market. To examine the factors and extent of influence of each mentioned organization on crude oil price offered an econometric model by using Johansen_ Juselius technique. Result shows that OPEC organization is effective on petroleum price with amount of crude oil supply and OECD organization is effective on it by harnessing oil reserves. The crude oil price is sensitivity to OPEC supply more than oil reserves is controlled by the OECD. So that OPEC organization can use it as a tool to increase bargaining power. Other variables can affect the crude oil price such as global economic growth and the effective real exchange rate America are analyzed in this paper. The result is that global economic growth has direct effect on crude oil price and real dollar exchange rate has an adverse effect on it.

Thermal power plant emissions are considered as one of the most important environmental pollutions. In this study environmental efficiency of electricity industry for NOx emissions is calculated. Our data include 6 power plants of three Khorasan provinces for 1384-1387. We rely on hyperbolic translog distance function specification that treats the outputs asymmetrically by allowing equiproportional desirable outputs expansion and undesirable outputs contraction. This function is implemented by using conventional econometric techniques based on panel data maximum likelihood estimation. The result shows that environmental efficiency for this sample of plants is 93.81 on average. In addition, our estimated shadow price for each kilogram of NOx is 1.12 Rials. Results of this kind of studies can be useful for decision makers to have a better environmental prospect for planning.
