Theory and ApplicationsIntroduces the concept of indifference pricing in models of discrete time and finite state spaces where duality theory can be exploited readily. This book also discusses utility indifference pricing for diffusion models, and addresses problems of optimal design of derivatives.Preface ix PART 1. FOUNDATIONS 1 Chapter 1.
