Like most of oil exporting countries, Iran’s economy is exposed to the government’s great share of economic activites, complicated monetary and economic policies and a meager activity in production section.Thus a shock in oil price has a significant effect on domestic production, inflation and money. On the proposed model of Qu and Perron (2007), the present study Investigates structural shocks of Iran’s economy stemed from exogenous oil price considering the variables of production, inflation and money as independent and endogenous variables during the period from March 1961 to February 2012. Accordingly, five structural shocks have been identified in September 1973, July 1979, May 1990, July 1994 and May 2006. The most considerable effect of oil price on production, inflation and money growth were in the first, first and fifth regimes respectively. Moreover, the longest period of oil price effects on production, inflation and money growth were in forth, second and fifth regimes respectively.

The analysis of efficiency trend by applying window Data Envelopment Analysis and research about environmental and structural forces affecting on efficiency in electricity distribution companies after vertical decomposition and ownership change in Iran is very important object. On the basis of circuit density, companies decomposed in two groups with low circuit density (group1) and high circuit density (group2). On the basis of research results, window efficiency mean of first and second groups under the variable and constant returns to scale with respect to metafrontier have had increasing and decreasing trend respectively. But second group efficiency mean is higher than first group efficiency mean into whole windows. Shiraz city, Golestan and Mazandaran electricity distribution companies in second group have had unsatisfactory performance with respect to metafrontier and group frontier in comparison to other companies. High circuit density companies have had fewer gaps between group performance and potential better performance or metafrontier. Network load factor increasing would be led to lower efficiency and transformator load factor increasing would be led to higher efficiency. Privatization has insignificant effect on efficiency in the short-run but has significant effect in the long-run.

In Lucas growth endogenous, we focus on human education that causes the weakness of decline return. Therefore the lack of autogenous technology cannot omit long term per capita growth. Human capital against autogenous growth model can be saved by investment i.e. people can choose how long they invest on education. So it is supposed that human capital is an accumulated input with fix return. Finally from the model concluded that in shortage of autogenous technical progress the long term growth rate can be explained by accumulation of human capital. In this paper it is tried to search the effect of human education on growth rate in Iran by Lucas growth endogenous. The model that has been used in this paper is estimated by time series of 1959-2007 and five steps co-integration approach of Johansson and Vector Error Correction Model. Finally, based on two obtained co-integrated vectors, it is concluded that in long term there is a positive relationship between index of knowledge oriented employment and increase of physical capital's accumulation on Iran's economic growth. In addition, both of these vectors show that knowledge oriented employment has been very influential in the economic growth of the country in the long term.
