In the Iranian economy, especially after the emergence of oil and its rise in price, we have witnessed a significant government presence in the economy and the payment of all kinds of direct and indirect subsidies to the society and manufacturing sectors. In 2010, the government took steps to liberalize prices in the energy sector and allocate proceeds to construction, housing, manufacturing, health and health sectors. Releasing energy prices can have an impact on the level of manufacturing and productivity. One of these industries associated with the daily lives of people is the food industry, which plays an important role in the economy.The purpose of this paper is to examine the effects of targeting subsidies on the productivity of food industry. Therefore, the statistical society, food industry of Iran and the research period have been considered from 2006 to 2013. Using the econometric model and with the help of Eviews software, the following results are obtained.The coefficients indicate that: The physical capital and machinery variable in the food industry is significant at 5% error level and Lee does not have the required productivity in the food industry. On the other hand, effective exchange rate is one of the variables affecting the growth of production as well as productivity. This variable is significant at the error level of 10% and has a positive effect on the productivity of food industry. The results of this paper show that the variable productivity of human capital in food industry is positive and significant.The results of this paper show that the variable productivity of human capital in food industry is positive and significant. Finally, the results show that the purposefulness of the subsidy, which is significant at 1% error level, has a positive and significant effect on the productivity of food industry. In enforcing the targeted subsidy policies, businesses have been able to improve their situation and experience a competitive environment in production and increase productivity.

This paper analyzes the dynamic relationship between housing market, stock market’s           general index and real effective exchange rate of Iran using VAR and MGARCH models. For this purpose, monthly data of time period between Farvardin 1383 till Ordibehesht 1395 (Persian calendar) have been used. Based on the obtained results, there is no significant effect of other markets’ returns on housing market returns, while there is a significant and negative effect of stock market and housing market returns on foreign exchange market returns. In addition, in this study, the effect of simultaneous fluctuations of the housing market, foreign exchange and stock markets have also been evaluated. The results show that each market is not independent from other markets and a single market fluctuations will affect on the other markets. Because of the degree of simultaneous fluctuations among three markets, in order to make decision in one market and reduce the errors in decision making, policy makers can also consider political tools in other markets. Furthermore, investors may allocate their assets to these three markets in order to reduce the risk of investment

The main objective of this study was to investigate the relationship between budget deficits, inflation and money supply growth rate in Iran as one of the most important subjects in macroeconomics. In many countries, the budget deficit policy is used as one of the tools of financial policy. The relationship between the government budget deficit and the macroeconomic variables is somewhat ambiguous. All data related to inflation, budget deficit and money supply growth rate have been collected from the Central Bank of the Islamic Republic of Iran and the Iranian Statistical Center. Econometric methods including stability test, White, Johansson and vector regression test (VAR) were used to examine the hypothesis. The results of the present study show a positive and significant relationship between budget deficit, inflation and money supply growth that confirms the hypotheses of the study.

Setting Exchange rate in a good manner, paying attention to its changes and the factors affecting it in any circumstances, can be a topic of discussion. On the other hand, an increase in non-oil exports has been the main economic policy of the Iranian government in recent decades. To get rid of single-product economy, the development of non-oil exports for the Iranian government is a necessity. Iran's share of global exports has not been dramatic over the past years, and this makes the development of non-oil exports necessary in order to reduce the country's economic dependence on oil revenues. In the present study, by stipulating appropriate model, from econometric method, ARDL model was used to examine the short-term and long-term effects of real exchange rate changes on Iran's non-oil exports during the period 1983-2013. Non-oil exports in this study have been measured using the variables of the real exchange rate, Iran's trading partners GDP, GDP and credit to the private sector. Estimation results suggest that symptoms of estimated coefficients are consistent with the theoretical basis of all variables, and results show that changes in the real exchange rate at level of 5% error in the short and long term have a positive effect on non-oil exports. Effect of Iran's trading partners GDP, GDP and credit to the private sector on non-oil exchange has been positive.

The purpose of this research is to investigate the cost of representation and growth of the company in the years companies were admitted to Tehran Stock Exchange. In this research, company growth is shown with two variables: asset growth and sales growth. With a sample of 168 companies during the years 1389-1393, the hypotheses of the research have been analyzed with the help of generalized least squares regression methods. The results of this research indicate that the cost of representation has a significant relationship with asset growth and company sales growth. Also, this research shows that company size and dividend policy have a significant effect on asset growth and sales growth.

The aim of this study is to show the effect of auditor industry specialization on the                relationship between auditing quality and level of cash holding on accepted firms in Tehran Stock Exchange. Information required for the study of the financial statements of 81 firms in the period 1390-1394 were collected. In this study, the independent variable and the dependent variable are auditing quality and the level of cash holding, respectively. The results of this study showed that the effect of auditor industry specialization has no effect on the relationship between auditing quality and level of cash holding. In other words, the amount of cash held is related to factors other than the auditing quality and the mutual influence of auditor industry specialization
