Long-run and Short-run Linkages Between Efficiency of Energy Use in National Output and Carbon Emission: Analysis for the Panel of South Asian Nations

Abstract

Higher economic output as measured in gross national product (GNP) may not always imply a higher quality of living. It has been the outcome of the long debate between growth and development of a nation. The aims of economic growth should be reconsidered because it has polluted the environment, wasted natural resources, harmed people’s quality of life, and failed to alleviate socioeconomic problems. It is also a common phenomenon to the economies of the South Asian region. The study is thus conducted to show the existence of long-run relationship and short-run interplays between output efficiency of energy use (GEU) and carbon efficiency of energy use (CEU) in the panel of countries in the South Asian region for the period of 1971–2014. The results show that there is a long-run and short-run association between energy efficiency in output and carbon emission as respectively measured in GEU and CEU. This means that in South Asia, energy consumption leads to an increase in both gross domestic product and carbon emissions. When GEU is used as the independent variable in vector error correction model (VECM), the result reveals that any short-run disequilibrium from the long-run stable connection will be adjusted over time, and the long-run stable relationship will be restored.
