Economic growth is one of the most important goals of macroeconomics in current communities and its rate shows the rate of increase or reduction of GDP and improvement or reduction rate of welfare of people. This study evaluates the important factors of economic growth in Iran based on the effects of subsidy targeting plan. The study period is 1991-2012 and the study variables are including time series of Iran economy. After performing unit root test and evaluation of the stationary of variables based on Augmented Dickey-Fuller Test (ADF), the model coefficients are estimated by concurrent equations system and Two-Stage Least Square Method (2SLS) in Eviews software. The study findings show that value added of various economic sectors has positive and significant impact on GDP and economic growth. As the government size is evaluated by government costs to GDP ratio, the coefficient of government expenditures variable is negative and significant at level 6% statistically. The coefficient of public level variable of prices is negative and significant and it shows that inflation phenomenon and increasing the price of energy carriers increase production costs in short-term and GDP growth rate is reduced. The elimination of paid subsidies to manufactures and increases of production costs of economic enterprises and serious economic sanctions reduce economic growth rate.

This study is devoted to test the inflation persistence in Iran. For this purpose, respect to the time series data on inflation in Iran (1972 - 2011), Autoregressive Fraction- ally Integrated Moving Average model is used. The results of this study show that based on methods of maximum likelihood and modified maximum likelihood degrees of differencing, respectively, are d1=0.482 and d2=0.483. Therefore, based on these findings, the inflation persistence hypothesis is not rejected in Iran. Gradual vanishing of inflation shocks, possibility of inflation is structural and regard to monetary discipline is the most important recommendations of this study.

Decreasing unemployment rate is one of the most striking objects for economic planners and decision makers; and achieves to this, will lead to solve a lot of economic and social problems. According to theory and empirical studies, total factor productivity growth has a determinant role in unemployment rate. This study investigates the impacts of total factor productivity on the unemployment rate in the economy of Iran, based on annual data spanning the period 1971-2009. Results of the study indicate that total factor productivity growth has a significant and negative effect on unemployment rate of Iran's economy in the short-term and long-term. On the one hand, Granger causality test shows two-way causality relationship between unemployment rate and total factor productivity rate in economy of Iran, both in the short-term and the long-term. Thus, promoting the level of technical knowledge (technology) and enhancing motivation of workforce for more and use full work as well as avoiding of determining wages as imperative and other production factors, can move toward increase total factor productivity and reduce unemployment rate of Iran’s economy.
