The Impact of Output Volatility on CO2 Emissions in Turkey: Testing EKC Hypothesis with Fourier Stationarity Test

Abstract This study uses the environmental Kuznets curve (EKC) approach to determine the dynamic short- and long-term impacts of the volatility of economic growth (VOL) on carbon dioxide (CO2) emissions in Turkey from 1980 to 2016. The results of the Autoregressive Distributed Lag (ARDL) approach indicate that there is a long-run relationship between CO2, per capita real GDP, and VOL. The coefficients obtained from the ARDL estimation indicate that economic growth increases CO2 emissions, but VOL decreases CO2 emissions in the long run. However, the coefficients obtained from the ARDL error correction model show that VOL increases CO2 emissions in the short run. We also find that the EKC is valid in Turkey.
