Adverse Selection Leading to Price Spirals
In markets with adverse selection, such as insurance, a price spiral can occur. When an insurer cannot distinguish between high and low-risk customers, it might set a single, high price. This price can deter low-risk individuals, causing them to leave the market. As a result, the remaining customer pool consists of higher-risk individuals, which forces the insurer to raise prices further to cover the increased costs. This cycle of rising prices and a deteriorating risk pool can continue, potentially collapsing the market.

Predicting Insurance Market Dynamics
An insurer offers a single-price travel insurance plan that covers trip cancellations. A new, highly-publicized weather forecasting model becomes available to the public, allowing travelers to predict with great accuracy whether their specific travel dates are likely to have severe, trip-canceling weather. The insurer cannot access this individual forecast data. What is the most likely effect on the insurer's business over time if they do not change their single-price model?
