Insurance Market Decision-Making

Consider a hypothetical society where no individual has any information about their personal likelihood of needing expensive medical care in the future. An insurance company offers a health plan to everyone at a single, uniform price. This price is calculated to cover the average medical costs for the entire population. Which of the following outcomes is most likely to occur in this market, and why?

True or False: In a health insurance market where future health risks are unknown to all parties, a uniform premium based on average population cost would likely be unattractive to most individuals because they would prefer to save their money rather than pay for a risk that may not materialize.

Rationale for Insurance Purchase Under Uncertainty

Insurance Premium Rationale

A small, isolated community of 1,000 people establishes a health insurance plan. No one in the community, including the plan administrators, has any information about who is more or less likely to need medical care in the future. The total expected medical cost for the entire community for the year is $5,000,000. Based on this, a policy is offered to everyone for an annual premium of $5,000. Which of the following statements presents the most compelling justification for an individual to purchase this policy?

Imagine a scenario where an entire population is offered a health insurance policy at a single, uniform price. Crucially, no one—neither the individuals nor the insurance company—has any information about who is likely to become sick in the future. The price is set to cover the average expected healthcare costs of the whole group. In this situation, the market functions well, with widespread participation. Which of the following statements best analyzes the fundamental reason for this outcome?

Consider a community of 100 individuals where no one knows their future health status. It is statistically known that 10 people will incur medical expenses of $10,000 each, while the remaining 90 will have no medical expenses. An insurance company wants to offer a policy that covers all costs for the sick and breaks even financially. To achieve this, the company must charge a uniform annual premium of $____ to every person in the community.
