The adverse selection death spiral occurs when private insurance companies:
A) charge higher-than-average prices for health insurance, which in turn drives off
healthy individuals and leaves only sicker, high-cost individuals, resulting in yet higher
premiums the following period.
B) find themselves with only healthy individuals to insure.
C) offer health insurance at average cost, which results in losses to the company.
D) refuse to insure very sick individuals.
Marginal benefit:
A) is the subsidiary benefit from an activity; for example, the main benefit from weight
training is an increase in muscle mass, and the subsidiary or marginal benefit might be a
reduction in cholesterol.
B) is the addition to total benefit due to undertaking one more unit of an activity.
C) must be increasing if total benefit is increasing.
D) normally increases as more of an activity is undertaken.
