Investigating the Impact of Energy Carrier Price Shocks on Iran's Economics: Dynamic Stochastic General Equilibrium Patterns (DSGE)

The purpose of this study was to investigate the impact of price shocks on selected energy carriers in household consumption basket and firm production functions (both supply and demand side of economy) simultaneously on macroeconomic of Iran. The stochastic dynamic general equilibrium model consisting of households, firms, foreign trade and government and central banks has been calibrated and simulated for the Iranian economy. The data related to the estimation of the research model were seasonally available for the period 1996-2006. The final model equations were linearized around the stable state using linearized stochastic equations by the method of Uhlig (1999: 40) as a spatially-state model in the Matlab programming environment. The results of the simulation and analysis of the model's immediate reaction functions show that all price shocks in selected energy carriers, while increasing production costs and creating inflationary conditions, reduce total consumption, total investment and total demand, and after reducing the production of non-oil products and total production, employment decreases. The results of variance analysis also show that most of the changes in employment (compared to production) are due to diesel fuel and electric shocks, respectively, so that 1,08 percent of employment changes (compared to non-oil production), due to diesel fuel shock and 1,01 percent due to electric shock. The severity of the adverse effects created at the employment level during the first 10 periods following the energy price shocks is significant, indicating the need to pay special attention to the unemployment rate when the subsidy targeting law is fully implemented.
