''Nonlinear Cointegration and Asymmetric Adjustement between Economic policy uncertainty and Gold price: Evidence from the United States''
( 2021, Vol. 41 No.3 )
The main objective of this paper is to estimate the interaction between gold price and US- EPU by using monthly data during the period span from January 1997 to September 2020. The threshold cointegration approach focus on TAR, C-TAR, M-TAR and consistent-MTAR is employed. Results indicate the evidence of asymmetry in the adjustment process to equilibrium. Unidirectional causality is reported between variables. In addition, gold price became cointegrated with economic uncertainty. The adjustment mechanism is asymmetric and the speed of adjustment to the equilibrium is different when the last equilibrium error has different signs.
