I am gratified that there is sufficient interest in the subject matter
so as to support the offering of a second edition of this monograph. The
of differential games dynamic interpretation and game theoretic
foundation form a powerful and vital methodology for helping us study
and understand marketing competition. This second edition offers a blend
of what proved to be successful with the first edition and new material.
The first two chapters, reviewing empirical and modeling research, have
been updated to include contributions in the last decade that have
advanced the area. I have not changed the essential content in the
duopoly analyses in chapters 3, 4, and 5. A notable addition to the
present edition are the new chapters, 6, 7, and 8, which offer analysis
of three triopoly models. In the final chapter, I offer my summary view
of the area and hope for continued contributions. I want to express my
appreciation for the support of Josh Eliashberg, editor of the
International Series in Quantitative Marketing, as well as Zachary
Rolnik, Director, and David Cella, Publishing Editor, of Kluwer. Their
encouragement has provided crucial motivation in this endeavor.
