Key Concepts

  • Absolute Advantage
  • Comparative Advantage
  • Opportunity Cost
  • Specialization
  • Gains from Trade

Learning Objectives

  • Differentiate between absolute and comparative advantage.
  • Calculate opportunity cost to determine comparative advantage.
  • Explain how specialization and trade based on comparative advantage lead to gains for all parties involved, even when one party has an absolute advantage in all goods.
  • Apply the concepts of absolute and comparative advantage to analyze real-world trade scenarios.

Educator Instructions

  • Introduction (5 mins)
    Begin by briefly reviewing the concept of opportunity cost. Engage students with a quick, relatable example, such as the opportunity cost of studying for an exam versus going out with friends.
  • Video Viewing (10 mins)
    Play the Khan Academy video "Comparative advantage and absolute advantage | Microeconomics". Instruct students to take notes on the key definitions and examples presented in the video.
  • Concept Clarification (15 mins)
    Lead a class discussion to clarify the definitions of absolute and comparative advantage. Use the examples from the video (Patty and Charlie producing plates and cups) to reinforce understanding. Emphasize that absolute advantage refers to productivity with the same inputs, while comparative advantage is based on opportunity cost.
  • Scenario Analysis (15 mins)
    Present students with new trade scenarios. Have students calculate opportunity costs for each party and determine who has a comparative advantage in each good. Discuss how specialization and trade would benefit both parties.
  • Wrap-up and Quiz Preview (5 mins)
    Summarize the key takeaways of the lesson. Briefly preview the format of the upcoming quizzes.

Interactive Exercises

  • Comparative Advantage Calculation Worksheet
    Provide students with a worksheet containing various production possibilities scenarios. Students calculate the opportunity costs and identify comparative advantages to determine optimal trade patterns.

Discussion Questions
