The game-theoretic modelling of negotiations has been an active research
area for the past five decades, that started with the seminal work by
Nobel laureate John Nash in the early 1950s. This book provides a survey
of some of the major developments in the field of strategic bargaining
models with an emphasize on the role of threats in the negotiation
process. Threats are all actions outside the negotiation room that
negotiators have ate their disposal and the use of these actions affect
the bargaining position of all negotiators. Of course, each negotiator
aims to strengthen his own position. Examples of threats are the
announcement of a strike by a union in centralized wage bargaining, or a
nation's announcement of a trade war directed against other nations in
negotiations for trade liberalization. This book is organized on the
basis of a simple guiding principle: The situation in which none of the
parties involved in the negotiations has threats at its disposal is the
natural benchmark for negotiations where the parties can make threats.
Also on the technical level, negotiations with variable threats build on
and extend the techniques applied in analyzing bargaining situations
without threats. The first part of this book, containing chapter 3-6,
presents the no-threat case, and the second part, containing chapter
7-10, extends the analysis for negotiation situations where threats are
present. A consistent and unifying framework is provided first in 2.
