CDC: Public Health Economics and ToolsEconomics is the study of decisions—the incentives that lead to them, and the consequences from them—as they relate to production, distribution, and consumption of goods and services when resources are limited and have alternative uses. CDC uses economics to identify, measure, value, and compare the costs and consequences of alternative prevention strategies. The site includes tools that can be used to evaluate the costs and burden of various health problems and the effectiveness and efficiency of health programs.
