Analysis of cooperative alliance constituted by companies with different technology levels by using Shapley value

This paper focuses on the cost function influenced by sharing the technology among the companies possessing different technology levels rather than economy of scale. Based on the game with this cost function, shapley value can be simplified by using its axioms. Thus we show simplified version of shapley value and examine the stability of solutions in three-person game. Then modified Shapley value is also discussed so as to give stable solution by relaxing some of the axioms.
