Abstract

This aim of this paper is to test whether or not there was evidence of financial crises ‘contagion’. The sovereignty debt bonds data for Brazil, Mexico, Russia and Argentine were used to implement such test. The ‘contagion’ hypothesis is tested using multivariate volatility models. It’s considered evidence in favor of ‘contagion’ hypothesis if there is indication of structural instability that can be linked in any sense to one financial crisis. The result suggests that there is evidence in favor of ‘contagion’ hypothesis
