We develop a bivariate spectral Granger-causality test that can be applied at eachindividual frequency of the spectrum. The spectral approach to Granger causality hasthe distinct advantage that it allows to disentangle (potentially) di®erent Granger-causality relationships over di®erent time...

Decomposing Granger causality over the spectrum allows to disentangle potentially different Granger causality relationships over different frequencies. This may yield new and complementary insights compared to traditional versions of Granger causality. In this paper, we compare two existing...

It is often believed that the consumer sentiment index has predictive power for future consumption levels. While Granger causality tests have already been used to test for this, no attempt has been made yet to quantify the predictive power of the consumer sentiment index over different time...
