The Credit Default Swap Market's Determinants
Greatrex, Caitlin Ann - Economics Department, Fordham University - 2008
This paper explores the ability of variables suggested by structural models to explain variation in CDS spread changes. Using monthly changes in CDS spreads for 333 firms from January, 2001 – March, 2006, I find that these variables are able to explain thirty percent of the variation in...
