Examining the relationship between fiscal decentralization, renewable energy intensity, and carbon footprints in Canada by using the newly constructed bootstrap Fourier Granger causality test in quantile.

Current paper studies the nexus between fiscal decentralization, renewable energy intensity, and carbon footprints in Canada. Preliminary empirical findings strictly reject the preposition of data normality and highlight that the observed nexus is quantile dependent. Additionally, our test looks for systematic deviations from zero in the causality at a certain quantile and frequency. In particular, we consider the bootstrap Fourier Granger causality test in quantile. At each frequency, we test the sample causality against the distribution of the median causality across frequencies estimated for that process, which may disclose the misleading causal link in previous studies using only traditional Granger causality. Our results show a negative one-way Granger causality from fiscal decentralization to carbon footprints (quantiles: 0.1–0.9) and renewable energy intensity to carbon footprints, respectively (quantiles: 0.1–0.9). Herein, results show a positive one-way Granger causality through fiscal decentralization to renewable energy intensity (quantiles: 0.3–0.7). These conclusions are used to formulate policy suggestions. [ABSTRACT FROM AUTHOR]
