"Diebold and Rudebusch have succeeded in writing a milestone book that will be used variously as a standard reference, a guide for future research topics, a text book, or as a convenient introduction to the topics of yield curve modeling and macro-finance. Hence, while forecasting (especially about the future) is always fraught with peril, I'm confident that copies of the book will find their way into many collections, and that they will be actively used when they get there."--Leo Krippner, International Review of Economics and Finance "[T]he methods presented in the book are of great importance in financial market practice. The book is designed for academics, students, and practitioners working in yield curve modeling and forecasting, and it will be useful for all interested in bond markets and their links with the macroeconomic environment."--Malgorzata Doman, Zentralblatt MATH
