Since the nationalization of the oil industry, especially after the 1979 revolution, Iran has always encountered economic sanctions. The oil embargo and international financial sanctions are the most severe sanctions imposed on Iran and have had significant effects on Iran’s macroeconomic variables. The current study aimed to analyze the effects of economic sanctions on Iran’s macroeconomic variables using a dynamic stochastic general equilibrium (DSGE) model based on the new Keynesianapproach. The simulation results showed that the intensification of the oil and international financial sanctions would 1) reduce foreign and government investment, technology innovation,export in the oil sector, and consequently oil production, 2) lead to a higher exchange rate and a decrease in the ratio of the central bank foreign exchange reserves to the monetary base, 3)reduce the GDP and non-oil exports and increase the inflation, which may cause stagflation, 4) increase household consumption and decrease household investment, 5) increase budget deficit, forcing the government to adopt policies to raise current expenditures and maintain housing and urban developmentbudget, which, in turn, will lead to a budget deficit and bond sales. The analysis of various optimal monetary policies in the context of economic sanctions and considering the contingent business interruption (CBI) loss function showed that the optimal simple rule, in the form of the producer price index, targeting monetary policy, could reduce the loss function and increase the importance value of output coefficient in themonetary policy.

The purpose of this paper is to investigate the optimal monetary and fiscal policies with emphasis on a non-inflationary exit from economic stagnation in Iran. In the first stage, Iran’s economy has been modeled in the form of a New Keynesian Dynamic Stochastic General Equilibrium model (NK-DSGE). After modeling and extracting the system of equations, the structural parameters of the model have been estimated by using seasonal data from 1989 to 2016 and also the Bayesian approach. The results show that monetary and fiscal expansionary policies increase production though they are associated with inflation. In the second stage, the optimal monetary and fiscal rules have been extracted from a social loss function, and accordingly the conditions of a non-inflationary exit from stagnation have been investigated. The results of the simulation show that the optimal monetary policy cannot by itself lead to the exit of the economy from stagnation without inflation. However, if this policy is applied along with an optimal fiscal policy, a non-inflationary exit from economic stagnation can be achieved.

In this study, we use a Dynamic Stochastic General Equilibrium (DSGE) model to investigate the household portfolio channel of monetary and credit shocks transmission in Iran. In this regard, we developed a canonical New Keynesian DSGE model with financial and banking sectors. The model is estimated by Bayesian method for the period 1990-2012. The result showed that the current and expected prices of financial and physical assets affected their optimal proportions in household portfolio. Second, banking sector had a significant impact on the household portfolio composition and also on the real sector variables. More specifically, a positive deposit rate shock reduced the proportions of financial and physical assets in household portfolio and increased marginal cost and inflation. This shock decreased investment and output. Third, a positive shock on stock price had negative effects on demand for other assets in household portfolio but these effects were discharged rapidly. Moreover, the housing price shock had similar effects on demand for mentioned assets but the effects were discharged slowly. The results emphasized the role of credit, banking and assets markets sectors in financial fluctuation, business cycles and monetary transmission in Iran.
