Özet

Using a novel Wavelet Nonparametric Quantile Causality approach, we investigate the time-quantile predictive content of Cable News-based economic policy uncertainty (TVEPU) for energy and precious metal commodities. Our results indicate that TVEPU possesses predictive power for both energy commodities and precious metals across various periods and quantiles. Additionally, we find that the predictive power of TVEPU is stronger in higher quantiles for both causality-in-mean and causality-in-variance.
