Independent variable Coefficient Independent variable Coefficient
REI 0.035 (0.648) REI 0.505∗∗∗ (0.003)
GDP 0.218∗∗∗ (0.001) GDP 0.528 (0.465)
PPI 0.213∗∗∗ (0.009) PPI -1.692∗∗ (0.015)
COE -0.196∗∗∗ (0.003) COE -0.005 (0.998)

∗∗ and ∗∗∗ imply significance at 5% and 1%. Where applicable, trend and constant are included in the estimation. The bandwidth determination is premised on the Newey-West automatic and Bartlett kernel. The probability values are presented in the parenthesis.
