This paper analyses the international linkages of the Korean economy using the GVAR model developed by Greenwood-Nimmo, Nguyen and Shin (2012a, J. Appl. Econometrics). By employing a combination of generalized impulse response analysis and forecast error variance decompositions, we uncover a...

We develop an empirical network model to study bilateral sovereign credit risk spillovers during the European debt crisis. We show that the spillover density is typically asymmetric with heavy tails. This confounds efforts to track time-variation in spillover activity using the mean-based...

The spillover index developed by Diebold and Yilmaz (Economic Journal, 2009, vol. 119, pp. 158-171) is widely used to measure connectedness in economics and finance. Abrupt increases in the spillover index are thought to result from major economic and financial events, but formal evidence of...
