Correlation Statistics

This paper investigates the long-term dynamic cross-correlation evolution between US economic policy uncertainty index (USEPU) and Guangdong carbon emission trading price (GDCP) from the multifractal detrended cross-correlation analysis (MF-DCCA) perspective. With the calculation of correlation statistics and fluctuation function, the beginning procedures of MF-DCCA, we find that the cross-correlation between USEPU and GDCP is significant and presents power law property. Also, with the Hurst exponent, we find that the long-horizon correlations between series are persistent. Moreover, we perform Rényi exponent and spectrum singularity check. The empirical findings reveal that the all the correlations are of multifractality and the correlation of GDCP holds the highest degree.

The Relationship

This paper investigates the relationship between economic policy uncertainty and corporate tax rates in a panel dataset of 126 countries throughout 2003–2018. We use the so-called “World Uncertainty Index” to measure the level of economic policy uncertainty. We utilize various estimation techniques and find a one-way causality from economic policy uncertainty to corporate tax rates. Specifically, a rise in economic policy uncertainty leads to higher corporate tax rates. We also discuss potential implications.
