The purpose of this paper is to design a Dynamic Stochastic General Equilibriummodel to examine the effect of trade rent-seeking on labor behavior in Iran's economy. The empirical results of the analysis of Impulse Response Functions indicate that, with the positive shock of the trade revenue, the trade rent-seeking rate has increased, and the labors has reduced its productive activity. In order to examine more precisely the welfare cost of rent-seeking, by Lucas's compensated variation pattern has been shown to decrease a 10% in rent-seeking rate it is increased households welfare benefit by 6%. Therefore, it is suggested that the economic policymaker with the import tariff setting based on the economic and society’s livelihood needs restricts the bargaining by the owners of the profit.

The purpose of this study is to investigate the effects of development Iran’s economy sectors on increasing the income of low, middle and high income urban and rural groups. To achieve this goal, the effects of development eight main sectors of Iran’ economy on income increase of urban and rural groups were studied by using social accounting matrix (2011) and structural analysis method. The results show that the effects of agricultural development and expansion on earnings income increment per unit increase in the final demand of this sector for all urban and rural income groups are higher than other sectors and the crude oil and natural gas sector has the least effect. Also, urban group income increase is higher than rural. Based on this, it is suggested that the agricultural sector be considered seriously in the process of development and decision-making programs for investment in the economic sectors as well as the need to pay attention to income groups.

This study has assessed the welfare effects based on increasing in the price of eight commodity groups. This research has been accomplished among Iranian urban households of different income deciles in terms of linear expenditure system via using Compensating Variations in the period 1372-1392 by time series data.  The results indicate that the increasing in prices leads to decreasing the welfare of lower income deciles rather than the higher income deciles, but with rising price a group commodity(and stability  of prices of  other commodity groups) in terms of reduced welfare, the most vulnerable income deciles is different. Based on the results, it is suggested that the amount and type of subsidy to the income deciles must be different, and special attention must be paid to low-income groups in the liberation of prices due to inflation.

The aim of this paper is to examine the impact of government fiscal policies on income distribution. For this purpose FAVAR method and quarterly data for the time period of 1393:q4-1369:q1 for 99 macroeconomic variables have been used. Impulse response functions show that a positive shock as size one standard deviation in government current expenditure, increases Gini coefficient and as result worsens income distribution. While, government development expenditure as well as direct and indirect taxes shocks reduce Gini coefficient and improve income distribution. According to the Findings, the government can reduce income inequality by reducing unproductive costs, increasing targeted development spending and improving tax system. Manuscript profile

The main purpose of this study is to investigate the interaction between institutions and development in the Middle East countries. To testing the hypotheses the Middle East countries were divided into two groups of oil exporting and non-oil-exporting, then the research models as systematic and three-stage least squares have been used by the data during the period 1996 to 2014 for the two groups. Wald, Kruskal-Wallis and least significant difference tests were also utilized in appraising the interaction between institutions and development.  The findings show that there is a significant difference between institutions and development interaction in the oil exporting and non-oil-exporting countries in the Middle East. In both groups, the estimated coefficient for the impact of development on institutions is more than the impact of institutions on development. Therefore, pay attention to development, automatically, in addition to improving its indices, upgrades the institutions conditions and improves the indices performance. This impact is exist by institution, also, but the variation speed is more by development.  Manuscript profile

This study investigates the effects of environmental regulations on manufacturing industries of the selected OECD countries (USA, U.K & Canada) using Porter Hypothesis (PH) and structure- conduct- performance- Paradigm (SCPP) during 1970-2013, by regarding to simultaneous equations, and considering interoperability among market elements.Pollution Abatement Capital Expenditures (PACE) and environmental innovations are substitute variables for environmental regulations and competitiveness subsequently. The results show that increased industries expenditure to reduce emissions significantly increases their innovations and this proves Weak Porter Hypothesis (WPH) indicating positive impact of environmental regulation on competitiveness of the industries. Therefore, environmental regulations promote not only environmental quality, but also improve the industries competitiveness. The results, also, confirm the view that environmental policies are a win-win strategy. Manuscript profile

The aim of this paper is to analyzing the persistency of inflation in Iran by using a general approach, with the goal of providing a plausible and acceptable explanation. For this, the inflation rate of Iran in period 1937-2016 and on the base of fractionally integrated (FI) approach was modeled and in the later phase inflation memory parameter has been estimated by using classic methods (the Geweke and Porter-Hudak semi parametric method  nonlinear least squares, exact maximum likelihood, and a minimum distance estimator) and Bayesian methods. The results of the estimation in both methods show that the inflation rate in Iran is stable. Stability of inflation rates has important implications for policy-making, especially monetary policy, so that due to the impact of economic shocks on inflation, its effects will be last for a long time. Therefore, it is necessary to policy makers identify the major sources of distorting inflation, including dependence on oil resources, no attention to the role and function of the reserve fund, the government budget deficit, central bank dependence and the existence of structural problems and consider appropriate approaches in this field.   Manuscript profile
