Title : Dependency or interdependency effect of the Corona-virus: Evidence of ADCC and copula multivariate GARCH models


Objective: This paper investigates contagion epidemic in a multivariate time-varying asymmetric framework, focusing on three European countries, namely United Kingdom, France and Italy, during the epidemic corona-virus.

Methods: Specifically, both a multivariate Gaussian copula model and the Asymmetric dynamic conditional correlation (ADCC) approach are used to capture non-linear correlation dynamics during the period January 22, 2020-April 30, 2020. The empirical evidence confirms a contagion effect from the epidemic country to all others, for each of the examined corona virus.

Results: The results also suggest that Italy is more prone to epidemic contagion, while the numbers of deaths turmoil has a larger impact than country-specific epidemic corona virus.

Conclusion: Our findings imply that policy responses to an epidemic corona virus are unlikely to prevent the spread among countries, making fewer domestic risks internationally diversifiable when it is most desirable.
