Step 1: Understanding the Concept:
In economics, resources are scarce. Choosing one option means giving up another. Opportunity cost represents the value of the next best alternative that is sacrificed to make a particular choice.
Step 2: Formal Definition:
Opportunity cost is the cost of the next best alternative foregone. It is not the total of all alternatives, but specifically the single most valuable one that was not chosen.
Step 3: Example:
Suppose a farmer has a piece of land and can grow either Wheat or Rice. If he chooses to grow Wheat, the amount of Rice he could have grown and the profit from it is the opportunity cost of growing Wheat.
Step 4: Final Answer:
Opportunity cost is the value of the next best alternative foregone. Example: If you spend $10 on a movie instead of a book, the enjoyment of the book is the opportunity cost.
