Economic Perspective

1.1 A viewpoint that envisions individuals and institutions making rational decisions by comparing the marginal benefits and marginal costs associated with their actions.

Scarcity

1.1 The limits placed on the amounts and types of goods and services available for consumption as the result of there being only limited economic resources from which to produce output; the fundamental economic constraint that creates opportunity costs and that necessitates the use of marginal analysis (cost-benefit analysis) to make optimal choices.

Opportunity Costs

1.1 The amount of other products that must be forgone or sacrificed to produce a unit of a product.

Utility

1.1 The want-satisfying power of a good or service; the satisfaction or pleasure a consumer obtains from the consumption of a good or service (or from the consumption of a collection of goods and services).

Marginal Analysis

1.1 The comparison of marginal (“extra” or “additional”) benefits and marginal costs, usually for decision making.

Scientific Method

1.1 The procedure for the systematic pursuit of knowledge involving the observation of facts and the formulation and testing of hypotheses to obtain theories, principles, and laws.

Economic Principle

Macroeconomics

Positive Economics

1.1 The analysis of facts or data to establish scientific generalizations about economic behavior.

Normative Economics

1.1 The part of economics involving value judgments about what the economy should be like; focused on which economic goals and policies should be implemented; policy economics.

Economizing Problem

1.1 The choices necessitated because society’s economic wants for goods and services are unlimited but the resources available to satisfy these wants are limited (scarce).
