Abstract

In recent decades, many countries have improved systematic control over monetary policy and stabilized inflation at moderate levels. There is a great literature on how to conduct a monetary policy. A lot of macroeconomists (for example Taylor, McCallum, Woodford and others) proposed specific monetary policy strategies, regimes and rules. This paper considers a dynamic stochastic general equilibrium (DSGE), and two basic factors have been applied. The first one is a belief that monetary policy has impact on real economic activity in the short run. This effect comes from the presence of rigidities, which give rise to non-neutral effects of a monetary policy. The second factor is a considerable improvement under theoretical frameworks used for monetary policy analysis. The research also presents a sensitivity analysis of the optimal rules to deep structural parameters and investigate properties of an optimal simple rule with respect to prevailing type of shocks. Finally, the study highlights how an optimal policy rule depends on model structure, on the model calibration and nominal rigidities.
According to the research findings, based on the theoretical expectations, the effect of a positive shock inflicted on the government investment leads to increase and gradual accumulation of fixed capital formation in the public sector. Among estimated parameters consumption is first affected and reduces, then employment increases consequently, finally production will also be affected. Also with the shock of oil revenues, increased oil revenues results in public investment at first, because the increase in oil revenues, the government increases development expenditure. Though increase in development expenditure is more than Increase in current expenditure. Enhancing development expenditure & construction spending causes total spending increase and as a result of increased production of oil income, consumption and total investment will rise. This increase leads to inflation too.
Though by increasing the inflation resulted from oil revenues, the monetary authority will react through reducing the growth rate of the monetary base.
