The impacts of nonferrous metal price shocks on the macroeconomy in China from the perspective of resource security

Abstract

In recent years, the price of international nonferrous metals has undergone drastic fluctuations, which could exert significant shock effects on macroeconomic variables. Based on the perspective of resource security, this paper reveals the relationship between the nonferrous metal price shocks and China's macroeconomic variables by establishing a Dynamic Stochastic General Equilibrium (DSGE) model embedded with nonferrous metal consumption and means of production blocks. The model is based on the optimal decision-making behaviours of three departments that satisfy multiple constraints to realize optimal policy making. Furthermore, the Structural Vector Autoregression (SVAR) method is applied to verify the shock effects of nonferrous metal price and obtain more robust results. The Bayesian results show that there is consistency among nonferrous metal price shocks, consumer reference shocks, wage bonus shocks, technical shocks, and price-adjusted shocks. The impulse response function results indicate that the stimulation of an international nonferrous metal price increase would have significant positive impacts on the macroeconomic variables of investment, money supply, consumption and total output but negative effects on labour demand. In addition, the impulse responses of wage levels and the rate of inflation to nonferrous metal price shocks present obvious lagging effects.
