Capital human made resources used to produce goods and services-enhances ability in the future Scarcity is an objective concept that describes a factual situation. Poverty is a subjective concept that refers to personal opinions on defined level of income.

(arguably the most important guidepost, sometimes called basic postulate of all economics) 4. Individuals make decisions at the margin (marginal- effects of a change in the current situation) 5.

(secondary effects-indirect impact of an event or policy that is not easily perceivable or often unintended or overlooked) 7. The value of a good or service is subjective and based on individual preferences 8. The test of a theory is its ability to predict, economics is scientific thinking based on theories and tests.
