SELF-INSURANCE WITH GENETIC TESTING TOOLS

The development of genetic testing creates opportunities to better target disease prevention actions. In this article, we determine how the genetic information modifies self-insurance efforts in different health insurance market equilibria with adverse selection. We show that a regulation prohibiting insurers from using genetic information for rate-making purposes: (1) cancels the benefits of genetic testing when pooling equilibria occur and (2) does not prevent the exploitation of the benefits derived from genetic testing when separating equilibria (both of the Rothschild-Stiglitz or of the MiyazakiSpence type) prevail in insurance markets.
