Managerial-flexibility

A classic text on Real Option Theory. In comparison with Mr Copelands Text on Real Options, Trigeorgis has more depths, but Mr Copelands book is easier to read, as Copeland targets practitioners. The chapter on Real Options for the analysis of competetive strategies is worth reading, and much better than Mr Copelands remarks on that topic, but possibly not fully up to date. The future of real options seems to lie in their combination with game theory, CFROI and dynamic oligopolistic markets. Mr Trigeorgis describes that field of research in its baby stage, as the book is 6 years old, but his theories are still much better, than many other books on that topic.

Real Options is the study of how to value potential business based on the real options they create rather than on discounting a simple stream of (erroneously) forecasted cash flows. Any business venture can be seen as a tangible corollary to a financial option, most commonly the Call or Put Option. For example, when Toyota and Honda build electric-fuel hybrid cars, they are not counting on an immediate stream of cash flows from hybrid car sales. Instead they are establishing a "Real" American Call Option on the ability to go to full hybrid car production ahead of the competition when the market for such vehicles manifests itself. How much they spend on their hybrid car programs is determined by finding the value of this option.

Lenos Trigeorgis shows how this is done. Conceptually, one can follow it well enough, but Lenos is merciless with the math. Still, one can grasp the basic concept by studying this book. A good read on the subject.

It's a very good book, which has changed my way of thinking in

some sense. Real options method is an exciting and challenging

subject in corporate finance.For sure, it deserves more

attention. Thanks for Mr.Trigeorgis'good job.
