Interest Rate Models Theory and Practice In implementing mathematical models for pricing interest rate derivatives one has to address a number of practical issues such as the choice of a satisfactory model, the calibration to market data, the implementation of efficient routines, and so on. This book aims both at explaining rigorously how models work in theory and at suggesting how to implement them for concrete pricing. This is an area that is rarely covered by books on mathematical finance. The book is meant both to help quantitative analysts and advanced traders price and hedge with a sound theoretical apparatus, and to encourage academics to develop a feeling for the practical problems in the interest rate market that can be solved with the use of relatively advanced tools of mathematics and stochastic calculus in particular. Advanced undergraduate students, graduate students and researchers should benefit from seeing how mathematics can be used in concrete financial problems.
