GDP growth and unemployment rate are both important factors that characterize economies. Okun (1962) examined data about GDP and unemployment rate and found that there was a negative relationship between these two variables. After that, economists reexamined this relationship and presented it in different forms such as difference version, gap version and production function form. Because of much debate that is done in recent years regarding the labour market, in this study with the aim of presenting scientific analysis of current conditions in Iranian economy, we used pesaran et al (2001) approach to estimate long-run and short-run Okun coefficients in an ARDL model and the data is for the period of 1974-2011. We found that there is long run relationship between variables in three models that we used. The results show that to reduse the unemployment rate to less than %10, GDP growth rate must be over %10. These results points to deterioration of current economic conditions. At the end, Analysis of Granger causality showed that there are unidirectional causality relationships in all three forms of Okun’s law.

Red meat and chicken meat are of crucial importance in Irans’ house holds food baskets. An increase in the price of red meat has an increasing direct effect on chicken meat. Meat market is very fluctuating but due to liberalization and the elimination of government intervention the market is usually balanced. In this paper the structure of price changes and the relation between whole sale and retail sale prices have been investigated and analyzed by using ARDL & ECM modeling. The results show that the elasticity of this reaction is about 1-15. One may conclude that the main reason for price changes is the price changes in the whole sale market, which is to be considered as of a great importance by policy makers to have a balanced market.

Survey the economic aspects of diffusion green house gases and their environmental effects are very important, especially with respect to the increasing diffusion of these gases.
In this paper, we evaluated relationship between diffusion of carbon dioxide gas and gross domestic product (GDP) per capita during period of 1353 to 1384(1972-2005), then formatted Environmental Kuznets Curve(EKC) for IRAN.
We used quadratic regression model that estimated by OLS. Results show that there is a defective form of EKC in Iran .with respect to the higher growth rate of spreading carbon dioxide to growth rate of GDP per capita, Iran economy is in the upward part of EKC. In the other words iran's economic and social status and conditions of economic growth did not let to decrease environmental pollutants through economic growth.

In economic studies of cooperatives, little attention has been paid to the different economic behaviors of cooperative and profit maximizer firms.There is a rich theoretical literature of cooperation theory which indicates that if the society wishes to catch the benefits of the cooperation, the coops must ignore profit maximizing behavior .Instead,they must attempt to maximize their own and their members' welfare.In this study, the economic behavior of the Iran's small cheese coops were analysed.For this purpose ,a panel data of 7 coops for 1995-2003 period were used.Results showed that these coops were profit maximizer firms and not cooperative ones, and hence the producers who deliver their raw milk to them, and consumers of their produced cheese didn't make benefit from the advantages of a real cooperation behavior in milk processing industry. Besides results show that analysed coops have not full efficiency in applying fuel and raw milk factors.
