Additional text

From the reviews:
“The book studies stable representations of constitutions. … the book is very well written and perfectly organized … . I can highly recommend the book by Bezalel Peleg and Hans Peters: a real pleasure for scholars working on effectivity functions and social choice functions, and a great learning opportunity for those who are not that familiar with the topics in question. It is an excellent contribution, bringing together a lot of material in a single manuscript in a coherent way.” (Agnieszka Rusinowska, Social Choice and Welfare, Vol. 40, 2013)
“The book presents in terms of effectivity functions (i.e. coalitional game forms) a very deep, clear and consistent exposition of the most important social choice problem–coalitional decision making. … Written by two authors who have made outstanding contributions to the developed theory, the book will be very useful for game and social choice experts, lecturers, and master’s and Ph.D. students in these fields.” (Fouad T. Aleskerov, Mathematical Reviews, Issue 2012 b)
