Interactions between energy and imports in Singapore: Empirical evidence from conditional error correction models

This study empirically tests for long-run equilibrium relationship and the direction of causality between imports and energy consumption in Singapore. The results of the present study reveal that a long-run equilibrium relationship exists between import growth and energy consumption growth in Singapore by using bivariate systems. Imports of Singapore converge to long-term equilibrium levels by 79.9 percent speed of adjustment through the channel of energy growth. Furthermore, the major finding of this study is that there are long- and short-term undirectional causalities that run from energy growth to import growth in Singapore, which denote that energy consumption in Singapore is a catalyst for importing.
