Oil revenues and taxes, respectively, are the first and second sources of government revenues in Iran's economy, with changes in their volume having significant effects on production, employment and ultimately, economic growth, which are the major objectives of the economy. The purpose of this paper was to assess the effects of tax shock on macroeconomic variables in an oil economy with the DSGE model approach. Estimation of model parameters was performed using seasonal adjustment time series data for the period of 1989 to 2017. The results indicate that a short-term tax shock has a negative effect on macroeconomic variables such as economic growth and consumption, but in the long run, with an increase in tax revenue, GDP growth and, consequently, consumption and investment in the economy have increased. In addition, the results reflect the fact that the effect of oil revenues alone on economic growth is positive, but with the introduction of explanatory variables, the amount of capital accumulation, due to the effect of oil revenues on this variable (effective mechanisms), has been negative.

The use of natural resource revenues for achievement of development has been a challenging issue for resource abound countries. These a challenging stem from the fact that incomes from natural resources are non-durable, unpredictable and uncertain. Many countries have pursued approaches and tools for managing these revenues to prevent economic fluctuations. The international organizations and economic experts propose a diversification into resource revenues in the form of different approaches for public investment. The present study evaluates the policy of increasing public investment in Iran in the form of three gradual, aggressive and conservative approaches for the period of 1978-2015 using a dynamic stochastic general equilibrium method. The results showed that after an oil revenue shock, the status of economic variables in the gradual increase approach is better than the other two approaches. In a gradual approach, in addition to increasing GDP and private and public consumption, public debt is also declining
