Cointegration tests of energy consumption, income, and employment

A recently developed methodology of the cointegration test is employed to determine whether energy consumption has a long-run equilibrium relationship with the level of income or employment. It is found that the long-run equilibrium relationship fails to exist in either case. The finding implies a long-run neutrality of energy consumption, which is consistent with the short-run neutrality found in the literature. The results are further confirmed by splitting the sample into two sub-periods.
