Persistence of shocks on sectoral non-methane volatile organic compound from 1820 to 2019: Insights from a fourier quantile unit root test

Despite being directly related to anthropogenic consumption and production, researchers have paid less attention to understanding the dynamics of non-methane volatile organic compounds. The primary objective of this research is to investigate the persistence of potential shocks to non-methane volatile organic compounds in 20 developed from 1820 to 2019 performing traditional unit root approaches and a newly developed Fourier quantile unit root test. Great portion of the empirical results obtained by traditional unit root tests reveal that the sectoral non-methane volatile organic compounds follow a non-stationary process, while the Fourier quantile unit root test indicate quite different results. The Fourier quantile test shows that non-methane volatile organic compounds are stationary in the United Kingdom, Ireland, Germany, France and Austria. In the other 15 countries, government interventions to reduce non-methane volatile organic compounds can have lasting effects and success. The inferences and policy outcomes of the empirical results are discussed in the main body of the paper.

Automated summary

This research investigates the persistence of potential shocks to non-methane volatile organic compounds in developed countries from 1820 to 2019, using traditional unit root approaches and a Fourier quantile unit root test. The results indicate that the non-methane volatile organic compounds follow a non-stationary process according to traditional unit root tests, but the Fourier quantile unit root test shows different results. The test indicates that non-methane volatile organic compounds are stationary in the United Kingdom, Ireland, Germany, France, and Austria.
