Health economics is a discipline of economics that studies the efficiency, effectiveness, value, and behaviour of health and healthcare producers and consumers. Interactions between individuals, healthcare professionals, and clinical settings are vital in understanding how to enhance health outcomes and lifestyle habits. Production, efficiency, disparities, competition, and regulatory theories are used by health economics to better inform the public and private sectors on the most efficient, cost-effective, and equitable course of action. Health economists assess a variety of financial data, including costs, charges, and expenditures. Economic appraisal of new technology, as well as the study of appropriate prices, antitrust legislation, optimal public and private investment, and strategic conduct, are all included in research.
