Output, renewable and non-renewable energy consumption and international trade: Evidence from a panel of 69 countries (original) (raw)

This paper uses panel cointegration techniques to examine the causal relationship between output, renewable and non-renewable energy consumption, and international trade for a sample of 69 countries during the period 1980-2007. In the short-run, Granger causality tests show that there is evidence of a bidirectional causality between output and trade (exports or imports), a one way causality running from renewable energy consumption to trade, and a bidirectional feedback causality between non-renewable energy consumption and trade. Interestingly, there is no direct short-run causality between the three variables renewable energy, non-renewable energy and output. However, there is an indirect short-run causality running from renewable energy to both non-renewable energy and output, which occurs through trade. Also, there is an indirect and bidirectional short-run causality between non-renewable energy and output through trade. In the long-run, OLS, FMOLS and DOLS estimates suggest that renewable and non-renewable energy consumption and trade have a positive and statistically significant impact on economic growth. Our policy recommendations are to encourage trade openness because this may reduce the share of nonrenewable energy consumption in total energy consumption. Indeed, through technology transfer and economies of scale, more trade openness could be a good policy for combating global warming by encouraging the use of renewable energies, while increasing output.
