Inter-firm collaborations are common in today's business world, but sometimes distrust can hinder their success. A new model using Game Theory has been developed to help manage distrust and promote trust among firms in business networks. This model requires a network governance actor with specific skills to guide the process. Game Theory is also used to study how competitors can collaborate, known as co-opetition. This research aims to understand why some collaborations fail and how trust can be built to improve business relationships.
