To this end, we first perform a static and dynamic analysis to measure the total volatility connectedness in the entire period (the system-wide approach) using a framework recently proposed by Diebold and Yılmaz (2014). Second, we make use of a dynamic analysis to evaluate both the net directional connectedness for each market and all net pair-wise directional connectedness. Our results suggest that slightly more than only 38.23%, of the total variance of the forecast errors is explained by shocks across markets, indicating that the remainder 61.77% of the variation is due to idiosyncratic shocks. Furthermore, we find that volatility connectedness varies over time, with a surge during periods of increasing economic and financial instability42 p.application/pdfengcc-by-nc-nd, (c) Andrada-Félixa et al., 2017http://creativecommons.org/licenses/by-nc-nd/3.0/Mercat financerAnàlisi de regressióAnàlisi de variànciaEstadística matemàticaFinancial marketRegression analysisAnalysis of varianceMathematical statisticsinfo:eu-repo/semantics/workingPaper2017-05-08info:eu-repo/semantics/openAccess
