Health economics is concerned with applying economic theory and methods of analysis to the production and consumption of health and health care. It involves studying how scarce resources are allocated among alternative uses for health care and improving health. Key aspects of health economics include efficiency in resource allocation, the health care market, demand and supply of health care, equity in health outcomes and care, and health sector budgeting and planning. Economic evaluation techniques used in health economics include cost-benefit analysis, cost-effectiveness analysis, cost-utility analysis, and cost-minimization analysis to compare costs and consequences of alternative health interventions or programs.
