| Abstract: | This paper develops a New Keynesian dynamic stochastic general equilibrium model with energy factors to study various channels through which China's economic fluctuations are linked to energy price shocks and to search for the optimal monetary policy to cope with energy price shocks. We conclude that there are channels through which changes in energy prices will have the following cause–effect relationships. First, a rise in energy price as a negative technology shock will raise the costs of providing capital services per unit of capital, thereby reducing output. Second, a rising energy price distorts the intertemporal choices of households and firms, creating downward pressure on the expected future return on capital. Third, an energy price shock places upward pressure on the marginal costs associated with an increase in inflation. Numerical simulation results show that a positive energy price shock has a positive effect on energy technology improvements. In addition, the effects of energy price shocks can be mitigated by nominal rigidities, and interest rate rules will determine the magnitude of those effects. Using the efficient frontier method, we also show that optimal monetary policy in China should help control energy price volatility. |
