Abstract

Although it is widely accepted that a decentralised system can enhance policy learning and the spread of best practices, an under-researched question is where that learning process takes place. Using data on the diffusion of health care policies in Switzerland, this article analyses the role of institutionalised intergovernmental cooperation and its impact on the spread of successful policies.The results show that joint membership of policy makers in health policy specific intergovernmental bodies is related to the diffusion of best practices.
