Asymmetric Information With Multiple Risks: The Case of the Chilean Private Health Insurance Market
Health Economics, Volume 35, Issue 5, Page 712-729, May 2026.ABSTRACT We extend the Rothshild and Stiglitz (1976) model to two sources of risk –inpatient and outpatient risk– to better proxy real‐world health insurance markets.
