This article discusses the results and prospects of the market reform in Dutch health care which came into force in 2006. Attention is paid to the results of the health insurance reform, the experience with the shift from passive to active purchasing and the impact of the reform on healthcare provision and cost control respectively. Other topics discussed are the consequences of the reform for administrative costs, institutional trust in health insurance, and the power balance in health care after reform. The central message is that the high expectations of the market reform have not come true. Dutch health care features a high degree of hybridity and there are indications that the system is becoming ever more hybrid: the system operates much less market-like than the market frame suggests. Currently, the policy narrative on the reform is changing. Policymakers and policy documents underscore the need for cooperation in provider networks and more state direction. The Dutch experience with health care reform illustrates the pendulum theory. After a period of a belief in competition and less state direction the pendulum in policymaking swings back to a belief in cooperation and a pro-active role of the state.
