Risk Selection in Natural-Disaster Insurance

It is widely recognized that market failure prevents efficient risk sharing in natural-disaster insurance, leading to several public-private partnership arrangements across the globe. We argue that risk selection by the private partner is potentially an important issue. We illustrate our concerns with a simple model of reinsurance in a natural-disaster insurance market, based on the French system. Risk selection is a likely equilibrium outcome. Notably, the policies implemented by the French government correspond to the ones we identify to alleviate risk selection. Next, we discuss two public-private partnership settings that deal effectively with risk selection: Florida and Spain.
