The purpose of the present research is to investigate the effective channels of the monetary transmission mechanism in Iran. To do so, we devised a New Keynesian Dynamic Stochastic General Equilibrium Model. In our model, the different types of nominal rigidities are introduced beside all the related structural equations, which are extracted and linearized around a steady state point. Furthermore, to design the DSGE model, two different monetary rules—Taylor and McCallum rules—are used. In other words, the different channels of monetary mechanisms are investigated on the basis of these two rules. To estimate the two mentioned models, seasonal data for the period 1990–2015 are collected. The estimation method used in the study is the Bayesian method. According to the results obtained from variance decomposition, in the Taylor rule-based, q-Tobin, interest rate, wealth and expectation channels are the effective channels in monetary transmission mechanisms; also, in the McCallum rule-based model monetary policy, wealth and expectation channels are the effective channels in monetary transmission mechanisms. In addition, based on the simulation results in the Taylor model, increasing interest rate causes a reduction in output, consumption, investment and capital utilization rate, and in the McCallum model, a positive monetary shock can cause an increase in preceding variables, which is a result of price rigidity.

Despite positive aspects of energy consumption, their negative externalities i.e., environmental pollutions, are considerable. Green taxes, paid for products and services that are not environmentally friendly, are recommended as an efficient way of improving health indices. Since, Iran is among the countries with high per capita consumption of energy, pollution can be a kind of threat. In this regard, to simulate the effect of green taxes on Iran’s health sector, we use a general equilibrium model, calibrated by Iran’s Social Accounting Matrix (SAM) in 2011. The results show green taxes reduces all kinds of environmental pollutions. Furthermore, 62% of health costs are spent on mortality, 26.4% on morbidity, and 11.6% on non-health effects.

This paper tries to analyze the impacts of intermediate goods trade on production, consumption, investment, net exports, employment, labor wage and capital rent of Iran in its bilateral trade relations with China. This analysis has been done by modeling, solving and calibrating an international real business cycles (IRBC) model in period 1980-2009. The results show that when elasticity of substitution between domestic and imported intermediate goods is low, increasing the share of Iran’s imported intermediate goods from China increases volatility of Iran’s macroeconomic variables. The value of an increase in volatility of Iran’s macroeconomic variables depends on elasticity of substitution between domestic and imported intermediate goods, when the elasticity of substitution between domestic and imported intermediate goods is low, an increase in the share of Iran’s imported intermediate goods from China leads to a further increase in the volatility of macroeconomic variables. These results indicate that imports of intermediate goods are an important path through for transmission of shocks between main bilateral trade partners.
