FO H /. ÂOH ÂN / D p n. FN //: (9) If the functional . / is “smooth enough”, it is fairly natural to expect that the asymptotic behaviour of (9) can be obtained by Proposition 1. The smoothness condition on . / that proves useful in this case is its Hadamard differentiability (cf. ). A map . / W DŒ 1; C1 ! E, E being an appropriate normed space, is Hadamard differentiable at the “point” G, with Hadamard derivative G0 . /, iff there exists a continuous, linear map 0 W DŒ 1; C1 ! 0 E as t # 0, ht !
This clustering, from an operational point of view, is a suitable categorization of the banks with respect to the shares of trading activities. 5 %, has the effect to separate the largest banks from the rest of the population. This value was triggered by the problem, to address a limited number of European banks that are so large compared to the others to be subject to supervision independently by their activities, for the potential impact they have on the whole system. The obvious alternative to the trimming parameter is to remove a priori these outlying banks from the analysis.
We follow an MCMC approach to parameters and latent variable estimation and provide evidence of significant volatility shifts in asset returns, strong simultaneous increases in cross-market correlations, as well as sharp declines in correlations patterns. Overall, these findings are highly consistent with various empirical characterizations of contagion put forward in the literature, allowing us to conclude that the recent financial crisis generated severe contagion effects in sovereign debt markets of eurozone countries.
