If you can´t beat ´em, join ´em cooperative and non-cooperative games in network sharing

No Mobile Network Operator (MNO) will make the decision to share its network lightly. There are many financial and strategic considerations to this question. In this paper we outline a non-cooperative game which can be used to model the strategic decision of an MNO regarding mobile network sharing in a typical oligopoly telecom market. We make an estimation of the financial considerations, as an illustration of how this question can be approached. Because our model uses preference orderings of outcomes to establish equilibria, it allows for a quick exploration of the positions regarding sharing. This is helpful for both operators and regulators to evaluate strategy and policy.
