Lesson 3: Scarcity | Unit 3: Opportunity Cost Page: 9 of 17

Topic: The Concept <=PAGE BACK | PAGE NEXT=>

With limited resources and unlimited wants and needs, a lot of opportunities are forgone, a lot of alternatives can't be pursued. This is the idea of opportunity cost.

A definition:

  • Opportunity cost is the highest valued alternative foregone in the pursuit of an activity.
Three points related to this definition:
  • Foregone Alternative: Opportunity cost means NOT doing something else, not producing another good. Using resources to satisfy one want or need means they can't be used to satisfy another.
  • Highest Valued: Opportunity cost is all about giving up the best alternative possible, the most satisfying. Any activity has many alternatives. Opportunity cost is not all of these alternatives, only the most preferred, the highest valued.
  • Pursuit of an Activity: Using resources to produce goods that are consumed to satisfy wants and needs. The key economic activities foregone are production and consumption.
