Professors Ho and
Lee are authors of the famous Ho and Lee interest rate model. Both have had long
and illustrative careers as academics and practitioners. As one might expect,
they have much to say about finance, and that is evident in the physical heft of
this book. Weighing 3.3 pounds, it is packed with information. Targeting
primarily a university audience, the book is positioned as an alternative to
Hull's (2002) aging classic.
Refreshingly, the
authors chart their own course. This isn't just an elementary introduction to
financial engineering. The book is a soup-to-nuts exploration of modeling in
finance. Topics include:
portfolio
theory,
equity, fixed
income and credit financial engineering,
financial risk
management, and
corporate
finance, including valuation and real options.
The authors may
have been influenced by the Black, Derman and Toy interest rate model. That
model was published in a completely non-technical article in the Financial
Analysts Journal. Not a single formula appeared in the entire paper yet, in
plain English, those authors explained to readers how to implement their model.
Such accessibility is no doubt a reason for that model's popularity. In this
book, Ho and Lee relegate most formulas to chapter appendices, favoring lengthy
plain-English explanations in the body of the text. I think, however, the result
is wanting. Black, Derman and Toy labored over the drafting of their paper for
months, writing and rewriting it over and over again. It was just a few pages
long. This book has 735 pages, so the authors had to spread their efforts more
thinly. The writing is good but not brilliant. Honestly, it could use some
polishing. More formulas would have clarified discussions. With formulas sparse, I think
readers will be frustrated. Another shortcoming is a complete absence of
exercises.

A challenge for
all authors of elementary financial engineering texts is the question of how to
use stochastic calculus. Readers of such books cannot be expected to have any
background in the subject, so what to do? Don't mention stochastic calculus?
Gloss it over? Delve into a lengthy but distracting introduction? Few books
handle the problem well, and this one is no exception. Targeting a mathematically
unsophisticated audience, the authors shun all use of calculus in the body of
the first few chapters. Then, when they start to discuss interest rate models,
they suddenly start tossing around stochastic differential equations. Ouch! The
students they were catering to in the earlier chapters are going to be lost.
Used in a
classroom, I think this could be a good text. It depends on the instructor. For
self study, I do not recommend it. Actually, it may appeal most to readers who
are more sophisticated than the target audience. Covering so many models, it
could serve as a competent reference. I think the treatment of interest rate models is
especially informative.
