The economic principle encompasses a wide variety of economic laws and theories that define or explain how an economy attempts to satisfy the unlimited demand in the marketplace with a finite supply of resources available to do so.

In corporate finance, as part of fundamental analysis, economic value added is an estimate of a firm's economic profit, or the value created in excess of the required return of the company's shareholders. EVA is the net profit less the capital charge for raising the firm's capital. 

Economics is the study of how man attempts to satisfy his unlimited wants and needs by way of limited resources. This relative scarcity of resources implies the existence of cost and the need for choice. 

In microeconomics, economies of density are cost savings resulting from spatial proximity of suppliers or providers. Typically higher population densities allow synergies in service provision leading to lower unit costs. 

Economies of scope are "efficiencies formed by variety, not volume". In economics, "economies" is synonymous with cost savings and "scope" is synonymous with broadening production/services through diversified products.
