Abstract

The contagion generated by the US subprime crisis and the European sovereign debt crisis that hit the Eurozone stock markets is still a highly debated subject. In this paper, we try to analyze the revision effect of the credit ratings of the Eurozone countries. To this end, we used a bivariate DCC-GARCH model to measure the extent of dynamic correlations between stock returns of our sample. Our results indicate that credit ratings revisions have a relatively limited effect on the dynamic correlations of the Eurozone stock markets.
