The aim of this paper is to study the technical, scale and technological efficiencies and also the changes in Partial and total factor productivities of provincial centers of Islamic Azad University. The methods used are DEA, Malmquist Index and a new approached known as truncated bootstrapped regression. The results indicate that out of 30 units of centers in the study, only 3 units are Fully efficient: Kermanshah, central Tehran and Yazd. For the periods under study (2010 and 2016), the productivity growths for all units have been positive and 18 units had TFP changes greater than one. The study revealed that environmental factors have effects on efficiency and productivity. Specifically, one percent increase in the ratio of the number ofthe professors and associate professors to total members will increase the efficiency by a factor of 0.89 percent. An increase in the age of unit and being in the metropolitan area increase the efficiency by the amount of 0.04 and 0.01 percent respectively.

The local and international environmental problems are one of the most important concerns for economists, politicians, and lawmakers. Therefore, an investigation of the relationship between economic growth and environmental pollution can be important ,because it may be used as a base for national and international environmental policies. In this study, a panel data approach was used to analyze the effect of economic growth, technical, preferential and political changes on the important air pollution factors in the 56 selected countries with different developments levels for the period 1995 - 2005.The results indicate that despite the positive effect of the economic growth on the environmental pollution, technological advances have played an important role in the reduction of sulfur and nitrogen dioxide,and in improvement of the political indices in the reduction of carbon dioxide as the air pollutant.

Present research study aims to test the capital-skill complementarity hypothesis in the context of Iranian economy. Capital and skilled labor are postulated to be complementary. Skilled labors are defined as those labors with university education. To test this hypothesis, sector-wise demand functions for this class of labor have been estimated. These sectors are classified as: agriculture, industry, public, social, personal and housing services and other services. The econometric results indicate that capital and skilled labor appear to be complementary in all production and service sectors. As such, introduction of policies such as tax credit investment would result in cost reduction in terms of investment expenditures, and increase in demand for skilled labor force. Across the production sectors, skilled and unskilled labor has appeared as substitutes while in service complementary to each other but with fuel it appears as complementary.

According to textbook arguments marginal cost pricing scores first on the effciency ground. However,if the monopolistic firm benefits from increasing returns to scale, the industry will not be financially viable. If this is the case, one option, which maximizes the welfare subject to a break-even constraint, is Ramsey Pricing. In this study this method of pricing is applied to the Iranian Electricity Industry.The prices are offered for different types of usage (residential, agricultural, public and commercial). The present study applies the direct price elasticity of demand for each usage as well as the marginal cost of producing, transmitting and distributing electricity.These prices are cpmputed by using a programme in MATLAB environment for peak and off-peak periods. Finally, the resulting welfare changes arising from applying Ramsey Pricing as an alternative model are estimated, and proven to be positive on balance.
