AP Microeconomics Unit 1 – Basic Economic Concepts: Comparative Advantage and Trade

Page 1: Key Concepts

• Absolute Advantage

  • Definition: The ability to produce more of a good or service with a given amount of resources than someone else.

  • Example: Canada produces 150 wheat while the US produces 100; Canada has an absolute advantage in wheat.

• Comparative Advantage

  • Definition: The ability to produce a good at a lower opportunity cost than competitors.

  • Example: A country may produce wheat more efficiently despite having lower technology if its opportunity cost is lower.

• Trade

  • Definition: The exchange of goods and services between countries, individuals, or businesses.

  • Benefits: Allows specialization in production, leading to increased efficiency and higher levels of production and consumption.

Page 2: Summary of Advantages

• Absolute vs. Comparative Advantage

  • Absolute advantage focuses on quantity produced; comparative advantage focuses on opportunity cost.

  • Trade based on comparative advantage boosts overall welfare and efficiency.

• Importance for AP Exam

  • Understanding opportunity cost is crucial for answering comparative advantage questions.

  • Two types of problems:

    • Output Problems: Focus on production quantities.

    • Input Problems: Focus on resource requirements.

Page 3: Determining Absolute and Comparative Advantage

• Absolute Advantage Example

  • Japan has an absolute advantage in steel (1200 > 1000).

  • Canada has an absolute advantage in coal (500 > 300).

• Comparative Advantage Calculation

  • Steel in Canada: 1/2 unit of coal (500/1000).

  • Steel in Japan: 1/4 unit of coal (300/1200).

  • Japan has a comparative advantage in steel; Canada in coal.

• Terms of Trade

  • Defined by opportunity costs; beneficial trade occurs when terms fall between the opportunity costs.

Page 4: Input Problems

• Absolute Advantage in Input Problems

  • Look for the country using the least resources.

• Comparative Advantage Calculation

  • Use the formula gain/give up.

  • Example: US has a comparative advantage in cars; Brazil in trucks.

• Terms of Trade Example

  • Acceptable terms: 1 truck for 1.5 cars.

Page 5: Key Terms to Review

• Absolute Advantage: Producing more efficiently than another entity.

• Comparative Advantage: Producing at a lower opportunity cost.

• Output Problems: Use monetary values; focus on production quantities.

• Input Problems: Use physical quantities; focus on resource requirements.

Page 6: Economic Concepts

• Opportunity Cost: Value of the next best alternative forgone.

• Free Trade: Unrestricted exchange of goods and services; enhances efficiency and competition.

• Input Problems: Challenges in resource allocation for production efficiency.

Page 7: Trade and Economic Implications

• Specialization: Focusing on a limited range of goods to enhance productivity.

• Terms of Trade: Relative prices for exchanged goods; crucial for understanding trade benefits.

• Trade: Enables specialization and efficiency, leading to economic gains.
