Market Failures in Healthcare

This topic offers an in-depth examination of the pervasive market failures that characterize healthcare systems, making them unsuitable for pure, unregulated competition. Tertiary students will analyze the breakdown of each standard assumption for a perfectly competitive market—including lack of consumer sovereignty, imperfect information, presence of externalities, and the option-good nature of healthcare—and their consequences for efficiency and equity. The module critically evaluates the quote that healthcare markets "fail every single one" of the conditions for Pareto optimality. For Zambian students in health economics and related programs, this topic is central to understanding the economic justification for government intervention in the health sector. It provides the analytical tools to diagnose systemic problems in Zambia's own healthcare market, from information gaps between patients and providers to the challenges of infectious disease externalities. Excelling in this area is essential for exams and forms the bedrock for designing and evaluating health policies, insurance models, and regulatory frameworks aimed at correcting these failures in the Zambian context.
