This research try to introduce the concept of horizontal collaboration, which firms are collaborating with another firms in the same level. Collaboration in supply chain is difficult to conduct, this research took one of the simplest form of collaboration which is information sharing. Competition asymmetry is not a new thing for the supply chain, therefore, this research also considers this condition by utilizing the Stackelberg game.
