        The aim of this article is to measure the dynamics connectedness of Tehran stock market with stock exchanges of selected countries from the Middle East and China, oil and gold markets, the dollar index and the euro-dollar and yuan-dollar. To this end, a variance decomposition approach has been used to measure connectedness of markets between January 2008 and the end of July 2019. The findings show that the variance of forecast errors in most of markets are due to the shocks of those markets themselves. The Qatari Stock Exchange has a significant impact on Saudi and UAE stock exchanges. As the time horizon increases, Brent's oil market will be more influential than other markets, and this market will be more affected by the stock exchanges of the Arab countries and the Shanghai Composite. According to the results, investing in the Tehran Stock Exchange and the yuan-dollar exchange rate due to insignificant dynamics connectedness with other markets is recommended to hedge risk.

        In the field of the new Keynesian school, this paper has been specified and estimated by the method of stochastic dynamic general equilibrium model in the small open export economy, in accordance with the structure of Iran's economy. Using the simulation results of the main model, while using the estimated parameters, the effects of oil shocks in recent years on selected macroeconomic variables have been evaluated. Determining the degree to which oil revenues affect economic indicators can, in addition to determining the degree of economic resilience, help policymakers determine future plans. The phenomenon of fluctuations in foreign exchange earnings from oil exports, due to the dependence of the structure of Iran's economy on oil revenues, affects all macroeconomic variables - both in the public and private sectors. Accordingly, it is proposed to reform the tax system and reduce dependence on oil revenues, diversify the government's revenue portfolio, commit to a balanced budget and prevent disproportionate growth of the monetary base, strengthen the role of the foreign exchange reserve fund and monetary discipline for the government.

        The impact of the development of information and communication technology on the labor market and social security has been the focus of international labor and social security organizations. This study examines the impact of ICT on Social Security Resources in the context of Iran’s economy during the period 1999 to 2019, using the Stochastic Dynamic General Equilibrium (DSGE) model, focused on duality of labor market (formal and informal).  The results of the study show that the development of information and communication technology affects social security resources by changing the structure of employment. A survey on the variables response to the positive impulse of ICT shows that the further increase in job opportunities in the informal sector provides more access to jobs in this sector and increasing in the participation rate, the number of informal workers increases. The finding show increasing in informal employment causes an increase in the lost resources of social security. Based on the results, it is suggested that policymakers and insurance funds develop flexible programs in order to expand insurance coverage and support informal workers with the participation of employers and the government.

        4 - Welfare costs of inflation using frictional unemployment in Iran:General Equilibrium Model approach

        The objective of this paper is to examine the welfare cost of inflation in the context of Iran's economy, incorporating labor market frictions (search theory) within a monetary general equilibrium model. The model also features a cash-in-advance constraint. To achieve this goal, through the utilization of calibration and sensitivity analysis in the steady state, the findings indicate that both employment and production are contingent on the elasticity of labor supply and the elasticity of vacancies in job matches. Depending on these two parameters, they may exhibit an increase in response to an escalation in the inflation rate. Additionally, the three-month optimal inflation rate in a stable state is determined to be 4.66%. The welfare gains, derived from reducing the three-month inflation rate from its current level of 5.3% to the optimal rate in a steady state, is calculated to be 0.0031% of total consumption. Therefore, based on the results, it is suggested that in inflation reduction policies, the effects of this reduction on welfare are taken into consideration, and special attention should be paid to the area of business investment by giving tax incentives, especially tax credits..

        Abstract The purpose of this paper is to investigate the distributive and welfare effects of the transition from the current payment system to a partially funding system in Iran. For this purpose a six period OLG Models have been designed and simulated. The simulation results of the specified model show that, the consumption of all generations has increased and the saving of individuals and, consequently, capital accumulation in the economy is decline due to these reforms; the result of these changes is the decline in total production of economy. Based on these results and the widespread recession in the country's economy, it is suggested that policymakers do not resort to structural reforms and transition to funded system. Manuscript profile
