Structural breaks and time-varying granger-causality: testing the spanning hypothesis
| Resumo: | This paper analyzes time-varying Granger-causality in the context of structural breaks and changes, employing recursive and recursive evolving window algorithms. A novel approach using the Flexible Fourier Form (Gallant, 1981) for modeling structural breaks is developed, and it is shown that there are no significant size distortions or power losses while accounting for structural breaks of unknown form and date in the deterministic component. Our methodology, applied to the Yield Curve Spanning Hy pothesis, reveals that the hypothesis cannot be universally upheld, as the yield curve only occasionally spans relevant information to predict yields. |
