Title: Contagious default: Application of methods of Statistical
Mechanics in Finance.
Abstract: Firms may default and thus not be able to honor their
financial obligations. Default is in general contagious (infectious).
Its study is therefore important for an institution holding a credit
portfolio of a large number of defaultable firms.
Interacting particle methods turn out to be a convenient tool to deal
with these phenomena. We shall study limit distributions when the
number of firms goes to infinity as well as their approximations when
the number of firms is finite but large. This allows to explain
various phenomena like default clustering and, in general, it allows
to view a credit crisis as a microeconomic phenomenon driven by
endogenous financial indicators.
