Arvinitis-Laurent-Gregory 1999 model, extend the Jarrow-Lando-
Turnbull credit migration model by giving dynamics to credit spreads.
After a review of the general structure of these one-firm models, we
will turn to the issue of building in multifirm default correlations.
Of various possible approaches, we favour stochastic time change as
the driver of correlation for its computational efficiency. In the
resulting multifirm credit migration framework, a variety of
approximation methods can be invoked to enable the efficient and
accurate computation of prices and hedges for basket credit
derivatives as complex as collateralized debt obligations.
