TY - JOUR ID - 30852 TI - A Change in Energy Intensity: Test of Relationship between Energy Intensity and Income in Iran JO - Iranian Economic Review JA - IER LA - en SN - 1026-6542 Y1 - 2006 PY - 2006 VL - 11 IS - 15 SP - 123 EP - 130 DO - 10.22059/ier.2006.30852 N2 - In this paper we study the long- term trend of energy intensity for Iran. We use a quadratic function of the logarithm of income to take account of the change in trend of energy intensity and test the non-monotonic relationship between energy intensity and income during 1967- 2002 We find that the long-run coefficient on squared income is negative and significant, indicating a change in trend of energy intensity.
