Review Questions

• How does adverse selection impact the functioning of health insurance markets?
  • Adverse selection occurs when those most likely to need medical care are the ones most inclined to purchase health insurance. This can result in a risk pool that is skewed towards higher costs, as healthier individuals may choose not to buy insurance. Consequently, insurance providers may raise premiums to cover the increased risk, which can further deter healthy individuals from enrolling, creating a cycle that threatens the sustainability of the insurance market.
• In what ways does moral hazard affect healthcare utilization among insured individuals?
  • Moral hazard influences insured individuals to potentially overuse healthcare services because they do not bear the full cost of their decisions. For example, a person with health insurance might be less inclined to consider cost-effective preventive measures or avoid unnecessary treatments since they feel insulated from the financial consequences. This can lead to overall increased healthcare spending and strain on insurance resources, impacting both premiums and policy availability.
• Evaluate the strategies that can be employed to mitigate the effects of adverse selection and moral hazard in health insurance.
  • To address adverse selection, insurers can implement measures such as mandatory enrollment policies or offer incentives for healthier individuals to participate in their plans. Additionally, risk adjustment mechanisms can help balance costs across different groups. To combat moral hazard, insurers often use cost-sharing methods like deductibles and co-pays that encourage consumers to be more mindful about their healthcare usage. Education on preventive care and wellness programs also play a crucial role in promoting responsible utilization of services, ultimately leading to better health outcomes and controlled costs.
