The market for financial
textbooks is crowded at both the introductory and doctoral levels, but much less so at the
intermediate level. Teaching opportunities at this level, however, are multiplying rapidly
with the advent of masters of science programs in finance (master in computational
finance, in mathematical finance, and the like) and the strengthening demand for
higher-level courses in MBA programs.
The Masters in Banking and
Finance Program at the University of Lausanne admitted its first class in the fall of
1993. One of the first such programs of its kind in Europe, its objective was to provide
advanced training to finance specialists in the context of a one-year theory-based degree
program. In designing the curriculum, it was felt that students should be exposed to an
integrated course that would introduce a wide breadth of topics in financial economics,
similar to what is found at the doctoral level. Such exposure could, however, ignore the
particulars and detailed proofs and arguments and concentrate on the larger set of issues
and concepts to which any advanced practitioner should be exposed.
Our ambition in this text is,
accordingly, first to review rigorously and concisely the main themes of financial
economics (those that students should have encountered in prior courses) and, second, to
introduce a number of frontier ideas of importance for the evolution of the discipline and
of relevance from a practitioner's perspective. We want our readers to be at ease with the
main concepts of standard finance (MPT, CAPM, etc.) while also being aware of the
principal new ideas that have marked the recent evolution of our discipline. Contrary to
introductory texts, we aim at depth and rigor; contrary to higher-level texts, we do not
emphasize generality. Whenever an idea can be conveyed through an example, this is the
approach we chose. We have, similarly, ignored proofs and detailed technical matters
unless a reasonable understanding of the related concept mandated their inclusion.
Throughout the book the emphasis is on the notion of competitive financial
equilibrium-what it means and how it is characterized in a variety of contexts ranging
from the Arrow-Debreu model to the consumption capital asset pricing model. These concepts
are presented as a platform for an in-depth understanding of the newer arbitrage pricing
approaches.
Intermediate Financial Theory
is intended primarily for masters level students with a professional orientation, a good
quantitative background, and a preliminary education in business and finance. As such, the
book is targeted for masters students in finance, but it is also appropriate for an
advanced MBA class in financial economics, one with the objective of introducing students
to the precise modeling of many of the concepts discussed in their capital markets and
corporate finance classes. In addition, we believe the book will be a useful reference for
entering doctoral candidates in finance whose lack of prior background might prevent them
from drawing the full benefits of the abstract material typically covered at that level.
Finally, it is a useful refresher for well-trained practitioners.
As far as prerequisites go,
we take the view that our readers will have completed at least one introductory course in
finance (or read the corresponding text) and will not be intimidated by mathematical
formalism. Although the mathematical requirements of the book are not large, some
confidence in the use of calculus as well as matrix algebra is helpful.
Over the years, we have
benefited from numerous discussions with colleagues over issues related to the material
included in this book. We are especially grateful to Paolo Siconolfi and Jeremy Staum,
both of Columbia University. We are also indebted to several generations of teaching
assistants-Francois Christen, Philippe Gilliard, Tomas Hricko,Aydin Akgun, Paul
Ehling-and of MBF students at the University of Lausanne who have participated in the
shaping of this material. Their questions, corrections, and comments have lead to a
continuous questioning of the approach we have adopted and have dramatically increased the
usefulness of this text. In addition to these, we would like to acknowledge our reviewers,
John Primus of California State University-Hayward and Victor Abraham of Pasadena City
College. Finally, we would like to thank the Fondation du 450eme of the University of
Lausanne for providing "seed financing" for this project.
