  The present article aimed to understand the effect of news shocks related to the technology on macroeconomic variables. In this regard, a dynamic stochastic general equilibrium model was used to analyze the reaction of macroeconomic variables in Iran based on seasonal data during 2001-2021. The results indicate that the news shocks increases the productivity of all production factors within one standard deviation. This increase escalates the wage rate as well as the interest rate. Household consumption, production and investment also increase opposing this shock. Due to the increase in production, the working hours will increase and consequently the inflation will decrease. Moreover, the economic prosperity grows due to the increased consumption and production. Manuscript profile

  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 aim of this paper is computing the welfare under different fiscal policies by using of  a Dynamic Stochastic General Equilibrium model in an optimal monetary and fiscal policy framework for the Iran's economy. In order to investigating the effects of using tax instruments some different scenarios were provided. First scenario, the case with all taxes available, Second scenario, the case without consumption taxes, third scenario, the case of income and consumption taxes. The results indicate that the number of fiscal policy instruments available to the planner, plays an important role in the welfare changes in the optimal monetary and fiscal policy model. The minimum welfare loss occurs in last scenario and the maximum of welfare loss is related to second scenario. The proposal is that planner deal with determining polices in an optimum fiscal and monetary policy model, regarding available fiscal policy instruments and effects from economic shocks on welfare changes.  Manuscript profile

  Abstract The purpose of this paper is to study the factors affecting Tradable and Non-tradable inflation. Accordingly, Dynamic stochastic General Equilibrium model was used during the period 1991 to 2016. The results of the Impulse Response Functions (IRF) indicate that non-tradable inflation is more responsive as a result of shocks. Monetary shock has had the greatest impact on non-tradable inflation, while Exchange rate and monetary shock have the greatest impact on tradable inflation in terms of initial effect and durability respectively. Based on the results, policy makers' attention to the components of inflation is suggested when economic decisions are made. Manuscript profile

  The aim of this study is to evaluate the result of the exsictance and change in consumer home bias on macroeconomic variables (such as consumption and inflation), in the event of exogenous shocks to the economy. In order to do so, seasonal data of the period 1394-1370 and a dynamic stochastic general equilibrium model has been used. After designing the model, parameters of the suggested model are estimated by Bayesian approach. Reviewing the impulse response functions in the event of exogenous shocks (such as oil revenue shock and technological shock) shows that, with home bias exsictance in the model, inflation and consumption volatility will reduced due to the increased volatility of exchange rate. Based on the results it is recommended that, In order to control endogenous variables (including inflation), In the event of exogenous shocks, especially oil revenue shock, the exchange rate should be allowed to fluctuate more.

  The purpose of this paper is to investigate the effect of existence of mark-up shocks, which is a criterion for monopolistic structure of industries on intensification of stagflation phenomenon in Iran’s economy. For this purpose, it has been utilized by the methodology of dynamic stochastic general equilibrium during the period of 1959-2014. The findings showed that mark-up shock increases price and decreases production which shows the existence of stagflation. Meanwhile, the mark-up shock will instantly decrease consumption and investment. As a result, mark-up shock does not have a positive effect on the economy as it tend to produce stagflation. Based on the results, it is possible that by consideration anti-monopoly laws it can be prevented increasing the mark-up. Manuscript profile

  Abstract         This paper examines an optimal fiscal policy model in the presence of agents heterogeneous in a dynamic stochastic general equilibrium framework. Therefore, the presence of heterogeneous agents in the model led to create limitation that will be call government preference. The role of these preferences and tendency of the Government to the poor or the rich group can change the results of optimal policies on the economy. By using a dynamic stochastic general model, the role of government preferences tendency was been surveyed. The results indicate that in these models, the role of government expenditure financing through available taxes in the policymaking system, is partly dependent on the government preferences tendency. On the bases of the results, it is suggested that separating the government preferences and tendency in relation to the poor and the rich. Manuscript profile

  The purpose of this paper is to examine the dynamics of exchange rates and the role of monetary and financial policies. For this purpose, we use a dynamic stochastic general equilibrium (DSGE) for a small open economy during the period of 1990-2016. The results show that in different scenarios there are signs of Dutch disease as a weakening of the trade sector, the strengthening of the non-trade sector, the increase in prices in the trade sector, the reduction of prices in the commercial sector and the reduction of the real exchange rate. Based on the results, active financial policies are recommended to control exchange rate fluctuations. Manuscript profile

  The purpose of this article was to investigate the replacement of traditional money with virtual currencies and its effects on macroeconomic variables with the approach of Dynamic Stochastic General Equilibrium (DSGE) models. For this purpose, the data of the period 2018-2019 with seasonal frequency have been used. In the model designed in this article, it is assumed that due to the use of virtual money, a substitution between virtual money and traditional money will happen in people's asset portfolio. In this study, the shock caused by the price and volume of Bitcoin transactions is considered as an indicator for the demand for virtual currency. The results show that the shock from virtual currencies has led to a decrease in the demand for traditional money, in other words, there has been a substitution between holding traditional money and virtual money. In addition, the results indicated that due to the shock of virtual currencies, the amount of consumption in the economy has increased, and on the other hand, the amount of government income from royalties and money printing has decreased. Also, the results showed that the government's tax revenues have also decreased due to the trend of financial resources in the economy towards the demand of virtual currencies. Manuscript profile

  Abstract In the literature, it is emphasized on the role of government spending in business cycle of economic activities, especially in the developing countries where public investment alongside with other government tools uses for economic growth stimulation. However, the effect of government spending depends on how the spending is financed. Oil in the Iranian economy plays a significant role, so that more than 45% of the budget is directly financed by oil revenue. Therefore, oil plays a major role in macroeconomic variables fluctuations. The aim of this paper is that while explaining the business cycle behavior of the oil income, its relation with some relevant macroeconomic variables including government expenditures, investment, growth, inflation and money is examined as well. To end this, we use a new Keynesian dynamic stochastic general equilibrium (DSGE) model to explain the transmission channels of oil revenues effect on macroeconomic variables through the government budget, public capital stock and monetary base channels.

  Abstract The purpose of this paper was to investigate the impact of stock market shock on macroeconomic variables with the approach of Dynamic Stochastic General Equilibrium (DSGE) models. For this purpose, the data of the time period 1990-2021 with seasonal frequency has been used. Modern financial systems usually include financing from the financial assets market in addition to financing the banking sector. The interaction between the stock market and aggregate activity has received much attention in the past decade. In this regard, traditionally, the stock price usually affects the stock market as the discounted current value of the expected stock profits. In this framework, stock prices are influenced by both production (through profits and dividends) and interest rates (through the rate at which future dividends are discounted). In this study, the capital market shock has an effect on the economy through the channel of consumption expenditures of households and investment expenditures of companies. The direct effects of stock price fluctuations on total spending have made the stock capital market known as a leading indicator in the economy. The obtained results indicated that the reaction of macroeconomic variables to the demand shock was more intense than the shock from the supply side, and only the variables of tax revenues and bank facilities showed a negative reaction to the demand shock in the conditions of the supply shock. Also, the amount of employment has shown a positive reaction in response to the shock on the supply and demand side in the capital market Manuscript profile

  AbstractToday To continue their economic life, financial institutions are required to adopt e-banking methods in order to be more competitive, reduce operating costs, increase profitability, and improve the quality of customer service. Electronic services and the development of e-banking are a big step towards reducing costs, reducing government spending and even controlling cost. This study aims to investigate the effect of e-banking in reducing banking operating costs and reducing government spending by using a random dynamic general equilibrium and considering the economic sectors of households, enterprises, government and monetary authority and information of private and public banks. To study in the period of 1375-1396. The results indicate that the use of electronic payment and receipt tools will lead to further reductions in bank costs, as well as lower energy prices and government spending.   Manuscript profile
