This paper provides a critical analysis of the subadditivity axiom, which is the key condition for coherent risk measures. Contrary to the subadditivity assumption, bank mergers can create extra risk. We begin with an analysis how a merger affects depositors, junior or senior bank creditors, and...

The aim of this paper is to combine two hitherto unrelated lines of research, namely the granularity adjustment technique for unsystematic credit risk and the theory of coherent risk measures. In theexisting literature, it has always been taken for granted that such a granularity adjustment is...

The granularity adjustment technique is embedded into a general multi-factor model. ... In this paper, a counter-example with negative value of the granularity adjustment is given for the well-known Vasicek (2002) model.

Value at risk (VaR) is today the standard tool in risk management for banks and other financial institutions.
