UNDERSTANDING COMPARATIVE ADVANTAGE: JOHN AND DAN EXAMPLE
Comparative advantage is an economic concept that explains how people can work more efficiently by focusing on tasks they perform better or faster than others. By dividing work based on comparative advantage, both individuals can save time and increase productivity.
The question asks:
“It takes brothers John and Dan the same amount of time to clean the room they share, but John can mow the lawn faster than Dan. Which action would allow them to take advantage of their respective comparative advantages?”
The correct answer is:
“John mowing the lawn and Dan cleaning their room.”
Why This Is the Correct Answer
John can mow the lawn faster than Dan, meaning John has a comparative advantage in lawn mowing. Since both brothers clean the room at the same speed, Dan can focus on cleaning while John handles the lawn. This division of labor allows both tasks to be completed more efficiently.
By specializing in the task each person performs relatively better, they save time and improve overall productivity.
Why the Other Answers Are Incorrect
“Them both sharing each task equally” is less efficient because John’s faster lawn mowing ability would not be fully utilized.
“Dan mowing the lawn and John cleaning their room” ignores John’s comparative advantage in mowing the lawn.
“Dan doing both tasks” would take more time because John is faster at mowing the lawn.
What Is Comparative Advantage?
Comparative advantage happens when a person, business, or country can perform a task at a lower opportunity cost compared to others. This concept is important in economics because it explains why specialization and trade can improve efficiency and productivity.
- People save time by specializing in tasks they do best
- Work can be completed faster and more efficiently
- Resources are used more effectively
- Productivity increases through specialization
Conclusion
The best way for John and Dan to take advantage of comparative advantage is for
John to mow the lawn and Dan to clean the room. This arrangement allows both brothers to complete their tasks efficiently by focusing on their strengths.
