In this work, we introduce the s,k-extremal coefficients for studying the tail dependence between the s-th lower and k-th upper order statistics of a normalized random vector. If its margins have tail dependence then so do their order statistics, with the strength of bivariate tail dependence...

Banks are linked through the interbank deposit market, participations like syndicated loans and deposit interest rate risk. the similarity in exposures carries the potential for systemic breakdowns. this potential is either weak or strong, depending on whether the linkages remain or vanish...
