Learning to share nicely: leveraging the Nobel prize winning Shapley value to enhance collaboration and co-operation in healthcare systems

Healthcare systems are facing mounting financial pressures, often intensified by structural fragmentation that fosters 'self-serving profit centres,' fuels a 'medical arms race,' and leads to a 'tragedy of the commons.' As these systems shift toward more integrated and collaborative models, the need for fair, efficient, and transparent cost-sharing mechanisms becomes increasingly urgent. The Nobel Prize-winning Shapley Value, derived from cooperative game theory, offers a principled approach to allocating costs and benefits based on each party’s contribution. This method not only promotes equity and accountability but also encourages sustainable collaboration toward shared objectives. Given the complexity of healthcare decision-making, the Shapley Value represents a promising approach that merits further exploration and evaluation in real-world settings.
