Health economics is the study of how limited resources are used in the health care industry and how they affect health care systems. It aims to provide the best quality health care to as many people as possible given financial constraints. Key aspects of health economics include cost accounting, cost-benefit analysis, cost-effectiveness analysis, and analyzing the effects of factors like technology, population changes, and policies on health care systems. Resources in health care may be evaluated using quantitative techniques like cost minimization and cost-effectiveness analysis.
