Final answer:
Health insurance can lead to increased demand for healthcare services because individuals face a lower out-of-pocket cost, leading to potential overuse and inefficient resource allocation when the societal cost exceeds the individual benefit.
Step-by-step explanation:
The question looks at how health insurance impacts the quantity of healthcare services people uses. In a scenario where a medical procedure costs $160, but a person with insurance only pays an out-of-pocket expense of $40, we’d expect to see a shift in the demand for healthcare. The insurance covers the remaining $120, which is offset by premiums, but those premiums do not change based on individual usage. Consequently, people might use more healthcare services than if they had to pay the full cost, leading to an over-consumption relative to the cost to society. This phenomenon is part of the moral hazard issue, where individuals with insurance consume more healthcare than they would without it, and this can lead to an inefficient allocation of resources, where the cost of producing healthcare services exceeds the value they provide to those individuals.
