10/26/2015Lesson 2: Cost40 Main Points People choose because resources are limited and insufficient to achieve all of their goals; people can’t have everything they want. It is easier to choose between goods and “bads” than good and goods. An economic decision involves using resources, goods or services Every economic decision involves a cost. There is no such choice as a free choice.
10/26/2015Lesson 2: Cost41 Main Points Opportunity cost is subjective and can only be identified by the decision maker. When people make a decision, they narrow the alternatives to two, select one (the choice) and give one up (the opportunity cost). Economics is the study of individual choices concerning the use of limited resources among competing goals.
10/26/2015Lesson 2: Cost42 Main Points Money is a tool for transferring resources into goods and services or exchanging one good or service for another Economics and finance are different. Economics is about resources; economic reasoning can be applied to finance. In a study of economics, needs and wants can’t be distinguished. Economic reasoning ranks wants according to priorities.
