Мини-курс «Современные модели теории торга» профессора Ханну Вартиайнена

 

Bargaining is about conflict – there is a common pool of resources and individuals with, at leat to some degree, diverging interest of how the resources should be used. Bargaining theory aims to understand how rational negotiation takes place and what is the predicted outcome of such negotiation process.

The axiomatic approach to bargaining takes as the starting point the outcome of the process, and asks what properties any such outcome should satisfy, if bargaining is characterized by rational, consistent behavior. The conditions – axioms - are then taken as constraints of the possible solution of the process. The aim is to identify enough conditions that leave us with a unique feasible bargaining solution. The non-cooperative approach, on the other hand, takes as the starting point the actual bargaining protocol, the game the bargainers play. Such game is characterized by the description of the order of moves and possible strategies. The solution is obtained by applying non-cooperative equilibrium concepts to the strategies. The Nash program seeks to combine the two approaches. The idea is to start with the axiomatic approach, to identify a normatively appealing outcome of the process. Then a non-cooperative game is developed that explains, in the sense of positive economics, why this particular outcome indeed becomes implemented. Implementation theory, in turn asks precisely the question of what outcomes can even in principle implemented of the players are rational. Thus implementation theory can be used to derive bounds on axiomatic solutions that meet the Nash program. 

 

The aim of the course is to provide an overview of the classic results on as well as some recent developments in bargaining theory. An attempt is made to provide an integrated view of the key insights.
