| Abstract: | Based on the EMU Broad Market indices, this paper reports studies of the intertemporal stability of the covariance (here as: cov./covs.) and correlation (as: corr./corrs.) matrices of credit spread (as: cr-spr.) changes on weekly data. For a multivariate framework, the Box and Jennrich tests are the most commonly used test statistics. However, it is shown that for small samples these tests are not well specified. A bootstrap-based statistical inference provides evidence that corrs. and covs. btw. various cr-spr. changes are unstable over the 1998-2003 period. |
