A Comparative Study of Public—Private Catastrophe Insurance Systems: Lessons from Current Practices

摘要

Natural disasters risk is increasing in several regions around the world as a result of socio-economic development and climate change. This indicates the importance of establishing affordable and sustainable natural disaster risk management and compensation arrangements. Given the complexity of insuring extreme risks, insurers and governments often cooperate in catastrophe insurance systems. This paper presents a comparative study of the main components and a broad range of indicators of fully private and fully public, as well as public-private (PP) insurance systems, for extreme events, in ten countries. This analysis results in the following nine main recommendations for policymakers who aim to establish new, or improve existing, insurance arrangements for natural disasters: (1) mandatory participation requirements are advisable to achieve a high market penetration rate; (2) adequate monitoring and enforcement mechanisms need to be put in place to ensure compliance with these requirements; (3) the government needs to take responsibility for part of the (extreme) damage in order to keep an insurance system financially viable and affordable; (4) private insurance companies should participate in a PP insurance scheme by selling and administering policies and by covering medium-sized losses; (5) the integration in systems of risk transferring mechanisms is advisable; (6) it is advisable that governments stimulate the building-up of insurers reserves by providing tax exemptions; (7) risk mitigation policies should be carefully integrated in a natural disaster insurance system; (8) a detailed assessment and mapping of risk provides the basis for an effective mitigation policy; (9) insurance should provide financial incentives for policyholders to take risk mitigation measures. © 2012 The International Association for the Study of Insurance Economics.
