In this paper, we deal with an axiomatic approach to default risk. We introduce the notion of a default risk measure …, which generalizes the classical probability of default (PD), and allows to incorporate model risk in various forms. We … discuss different properties and representations of default risk measures via monetary risk measures, families of related tail …
