Introduction
In game theory, the Rubinstein bargaining model is a solution to the problem of finding an optimal agreement between two parties who have conflicting interests and asymmetric information. For example lets just say two parties Bob and Alice, engage in a series of alternating offers and counteroffers on a resource that is valuable to both, until they reach an agreement or until they reach a predetermined deadline. How will they behave or what are the necessary steps must be taken by each player? What are the possibile results in the end of the bargaining? In this chapter you will find further details and deepdives about Rubinstein Bargaining concept and solution.
Problem Definition
In the Rubinstein bargaining model, two parties usually referred to as "players," are trying to reach an agreement on the division of a pie, where the pie represents a set of resources that are valuable to both parties. The players have conflicting interests and asymmetric information, meaning they have different preferences over how the pie should be divided, and they need complete information about the other player's choices. The Rubinstein model is a two-stage game.
In the first stage, each player offers the other player how the resource should be split. In the second stage, the other player can accept the offer, reject it, or make a counteroffer. The game continues with the players making alternating offers and counteroffers until they reach an agreement or until they reach a predetermined deadline. The players are assumed to be rational and have complete information about their preferences but not about the importance of the other player. The goal of each player is to maximize their utility, which is the measure of their satisfaction or happiness with the outcome of the negotiation. The Rubinstein model seeks an equilibrium, a stable agreement that either player cannot improve upon.
Rubinstein Bargaining game has 3 definitive rules that must be followed through as each stage performed.
- The negotiation begins with an initial offer from one of the parties.
- Initial offer must receive a response in form of either accept, reject, or a counteroffer.
- Bargaing must end with either an agreement is reached or a predetermined timeout deadline is set.
Fact: The model does not specify a fixed number of stages or a fixed deadline, and the actual number of stages and the length of the negotiation will depend on the specific circumstances of the negotiation.
