"Overall this book provides an excellent summary of the state of knowledge of term structure modelling. It combines a solid academic background with the practical experience of someone who works in the financial sector." Alan White and John Hull, A–J Financial Systems, Canada The modelling of exotic interest–rate options is such an important and fast–moving area, that the updating of the extremely successful first edition has been eagerly awaited. This edition re–focuses the assessment of various models presented in the first edition, in light of the new developments of modelling imperfect correlation between financial quantities. It also presents a substantial new chapter devoted to this revolutionary modelling method. In this second edition, readers will also find important new data dealing with the securities markets and the probabilistic/stochastic calculus tools. Other changes include: a new chapter on the issues arising in the pricing of several classes of exotic interest–rate instruments; and insights from the BDT and the Brennan and Schwartz approaches which can be combined into a new class of "generalised models". Further details can be found on the links between mean–reversion and calibration for important classes of models.
