The Effect of Oil Export Shock and its interaction with Monopoly Power on Iran’s Macroeconomic Variables: DSGE Approach

Due to the nature of oil price fluctuations on the world market, which has been facing a number of positive and negative shocks, In this paper we examine how oil price and mark-up shocks which is an indicator of monopolistic structure of industries will effect macroeconomic variables. So, we simulate Iran’s economy by the methodology of DSGE during the period of 1959- 2015. Period the results illustrate that the effect of mark-up shock on GDP, export, investment, and consumption is negative and on inflation is positive. So we can conclude that a rise in mark-up will result in a negative impact on household’s welfare. Meanwhile, a negative oil price shock increase import and consumption but decrease investment and labor’s demand. We can conclude that due to the dependence of the Iran’s economy on oil revenues and a decrease in oil price, and also an increase in mark-up, GDP and investment have decreased.
