In Iran, oil supplies the needed fuel and is the main source of foreign exchange earnings. Thereby, any volatility in oil prices will affect Iran's foreign exchange earnings at first and economic growth through time. This study, using Structural Vector Auto Regression (SVAR) model, investigates the effects of oil price volatility on economic growth of Iran through some institutional, monetary and financial variables during the period 1981-2017. The results show that the impulse of oil price volatility has a negative reaction from the growth of production. The index of democracy's reaction to the oil volatility is negative and, given its direct relation to production growth, overall production growth is reduced. Similarly, as for the government expenditures, it leads to reduced production growth. But the M2 has a positive reaction to the volatility of world crude oil prices and also has a positive effect on the production growth in the short run. The results also show that the most important variable affecting production growth changes in both the short and long run is the impact of government expenditures changes. Then, for achieving sustainable growth and using private sector dynamics, the assignment of public sector companies to the private sector based on the Article 44 of the Constitution should be followed.

Undesirable environmental changes such as global warming and greenhouse gases emissions rising have created much concerns worldwide during recent decades. Environmental problems emerged from economic activities have become a controversial problem due to achieve higher economic growth rate. The aim of this research is to investigate the effects of economic growth, trade and financial development on environmental quality in Iran. To this end, the statistical data during the period of 1970-2011 has been used. Also by using the Auto Regression Model Distributed Lag (ARDL) short-term and long-term relationships between the variables of model were estimated and analyzed. The results show that financial development and economic growth increase the degradation of the environment. In addition, the rise in trade openness reduces the degradation of the environment. Error correction coefficient (ECM) shows that in each period 51 percent of imbalance will be compensated and it closes to its long run process. CUSUM and CUSUMSQ tests show that the estimated coefficients are stable over the period.

Empirical studies show that money has real effects in short-run but is neutral in long-run. According to transmission chanels of monetary policy, there is a possibility that each sector has a different response to monetary shocks. This paper, using the BVAR method and seasonal data, investigates the sectoral effects of monetary shocks during 1988:Q2 to 2011:Q2. The results show that monetary shocks have real effects in short-run and the reaction of sectors are different. In addition, the effects of moneatary shocks on services and industry sectors are stronger than on agriculture sector.

Increasing productivity, as a way to reduce the gap between supply and demand and also as a factor to reduc the production costs and to increase the efficiency of resources use and the quality and competitiveness of products, is considerable for economists and policymakers. On the other hand, the reduction of unemployment is another challenge facing the countries of the world too. But the ambiguity to achieve both goals simultaneously has been appeared in the recent theoretical and empirical studies. The main question in this study is whether productivity enhancing, causes reduction in Iran's indusrial employment? to address this question, a multivariate structural VAR model, including industrial labor productivity, employment and CPI for the 1973-2007 period has been applied and the data gathered from APO, statistic center and central bank of Iran. Estimation of structural model is based on Blanchard-Quah decomposition approach. The results show that promoting productivity policies have little role and importance in the employment variations, thereby its size in reducing employment in the long run is negligible.
