Electricity consumption, economic growth, urbanisation and trade nexus: empirical evidence from Iceland

Abstract

This study empirically investigates the relationship between economic growth, electricity consumption, trade and urbanisation in Iceland, covering the period 1965-2013. The A.R.D.L. bounds testing approach to co-integration is applied to investigate the existence of the long-run relationship. The causality was investigated among the variables using Granger causality under the V.E.C.M. framework. The A.R.D.L. bounds testing approach to co-integration confirms a long-run relationship between electricity consumption and its regressors. The empirical estimation indicates the existence of a positive and statistically significant impact of economic growth, trade and urbanisation on electricity consumption for Iceland, not only in the long-run, but also in the short-run. Furthermore, electricity consumption converges to its long-run position by 45.63% speed of adjustment using the channels of urbanisation, trade and economic growth. The results of Granger causality imply the presence of a feedback causal relationship between urbanisation and electricity consumption in the long-run, thus validating the feedback hypothesis. However, economic growth is causing trade, thus validating the growth-led trade hypothesis in the short-run. Additionally, no causal relationship was found between electricity usage and economic growth, which confirms the neutrality hypothesis. Implementing the energy conservation policy will have no damaging effect on economic growth for Iceland.

Electricity Consumption and Economic Growth: A Revisit Study of Their Causality in Malaysia

“…The first strand of empirical literature focused on past studies which are conducted in different countries context, while the second strand of the empirical literature is focused on the Malaysian perspective. Faisal et al, (2018) confirms a long-run relationship between electricity consumption and its regressors. The empirical estimation indicates the existence of a positive and statistically significant impact of economic growth, trade and urbanization on electricity consumption for Iceland, not only in the long-run but also in the short-run.…”

The relationship between electricity consumption, trade openness and economic growth in India

“…Motivated by some recent studies on electricity use and economic activity nexus (e.g. Faisal et al, 2018;Salahuddin et al, 2018;Zhang, 2018), the main methodological steps and techniques applied for estimation of relationship between the above-cited variables are shown in Fig. 6.…”

“…Indeed, electricity is the most versatile and broadly utilised form of energy. The electricity consumption is a widely used indicator of the socioeconomic development and well-being of a country (Best and Burke, 2018;Faisal et al, 2018). More importantly, the growth in electricity consumption is mainly driven by developing countries.…”

Assessment of the factors influencing competitiveness fostering the country’s sustainability

“…The first and most important step in time series analysis is to check the unit root. The most appropriate method can be used for verification from a wide range (Faisal et al, 2018;Popovi c & Eri c, 2018;Sasongko et al, 2019): Dickey-Fuller (DF) test, Augmented Dickey-Fuller (ADF) test, Philip Perron (PP) test, Kwiatkowski-Phillips-Schmidt-Shin (KPSS) test.…”
