What is defined as "market failure" in the context of healthcare?

Market failure in healthcare is defined as a scenario where the healthcare market is unable to allocate resources efficiently, leading to suboptimal health outcomes. This situation occurs when there are significant inefficiencies in market operations, resulting in either an oversupply or undersupply of healthcare services and products, which ultimately affects the quality of care that individuals receive.

The concept of market failure in healthcare is critical because the market does not operate like typical goods and services due to unique characteristics such as the presence of information asymmetry (where providers have more information than patients), externalities (unintended side effects of healthcare services that affect third parties), and the necessity of healthcare as a basic need. These factors can prevent the market from self-regulating and achieving optimal results for the population's health.

Understanding this definition helps clarify why health economies require intervention, whether through regulation or public policy, to address these market failures and improve healthcare outcomes for society. The other choices, while related to healthcare dynamics, do not accurately capture the essence of market failure as defined in economic terms.
