Comparative Advantage and Gains from Trade - AP Macroeconomics

1. What does a point on the PPF curve represent?

   Efficient production use of resources. All resources are fully employed and allocated optimally.

2. What does a point outside the PPF indicate?

   Currently unattainable production with given resources. Requires more resources or better technology than currently available.

3. What does a shift in the PPF signify?

   A change in resource availability or technology. Changes in productive capacity due to external factors.

4. Find the opportunity cost of 1 apple if 3 bananas can be produced instead.

   $Opportunity cost = \frac{3 \text{ bananas}}{1 \text{ apple}} = 3 \text{ bananas per apple}$. Represents the trade-off for producing one additional apple.

5. What is a production possibilities frontier (PPF)?

   A curve showing maximum attainable combinations of goods. Represents the production constraint given available resources and technology.

6. Calculate the opportunity cost of 1 book if 2 pens can be produced instead.

   $Opportunity cost = \frac{2 \text{ pens}}{1 \text{ book}} = 2 \text{ pens per book}$. Demonstrates the sacrifice needed to produce one additional book.

7. What is the impact of technological advancement on PPF?

   Technological advancement shifts the PPF outward. Improved technology increases productive capacity.

8. Which concept explains why countries trade?

   Comparative advantage explains why countries trade. Each country specializes in goods with lower opportunity costs.

9. How does trade affect a nation's PPF?

   Trade does not shift a nation's PPF. Trade affects consumption possibilities, not production capacity.

10. What does a straight-line PPF indicate?

    Constant opportunity costs. Resources transfer between goods at a fixed rate.

11. Determine the comparative advantage if Country A's OC is lower for wheat.

    Country A has a comparative advantage in wheat. Lower opportunity cost determines comparative advantage.

12. What is the effect of trade on total world production?

    Trade increases total world production. Specialization based on comparative advantage increases efficiency.

13. How does specialization relate to comparative advantage?

    Specialization occurs in goods with comparative advantage. Countries focus production where they have the lowest opportunity cost.

14. What does a point inside the PPF indicate?

    Inefficient use of resources. Resources are not being used at full capacity.

15. What is the effect of trade on global resource allocation?

    Trade improves global resource allocation. Resources flow to their most efficient uses globally.

16. Identify the principle that underlies gains from trade.

    Comparative advantage underlies gains from trade. Countries benefit by specializing in their lowest opportunity cost good.

17. Which type of advantage relates to opportunity cost?

    Comparative advantage relates to opportunity cost. Absolute advantage focuses on resource efficiency, not opportunity cost.

18. What determines the slope of the PPF?

    The opportunity cost of the goods. Steeper slopes indicate higher opportunity costs.

19. What happens to the PPF with a decrease in technology?

    The PPF shifts inward. Technological decline reduces the economy's productive capacity.

20. What does a bowed-out PPF indicate?

    Increasing opportunity costs. Resources become less suitable as production shifts between goods.

21. Which concept allows for increased consumption beyond PPF?

    Trade allows for consumption beyond PPF. Trade enables access to goods beyond domestic production limits.

22. What is the significance of a comparative advantage in the global economy?

    It boosts global efficiency and trade. Enables countries to specialize and increase overall world output.

23. What is the result of trade based on comparative advantage?

    Mutual gains from trade. Both trading partners benefit from specialization and exchange.

24. What is the opportunity cost of producing more of good A?

    The quantity of good B that must be forgone. Reflects the fundamental economic problem of scarcity.

25. What is the definition of comparative advantage?

    Ability to produce a good at a lower opportunity cost. Measured by what must be given up to produce one more unit.

26. How does trade affect consumption possibilities?

    Trade can expand consumption possibilities. Allows consumption beyond domestic production possibilities.

27. What is the definition of absolute advantage?

    Ability to produce more of a good using fewer resources. Measured in total output per unit of input.

28. What does the term 'gains from trade' refer to?

    The benefits from specialization and exchange. Countries benefit mutually when they trade based on comparative advantage.

29. How does specialization affect production costs?

    Specialization reduces production costs. Economies of scale and expertise reduce per-unit costs.

30. Calculate the opportunity cost of 1 car if 4 TVs can be produced instead.

    $Opportunity cost = \frac{4 \text{ TVs}}{1 \text{ car}} = 4 \text{ TVs per car}$. Shows what must be sacrificed to produce one additional car.

31. State the formula for opportunity cost.

    $Opportunity Cost = \frac{\text{Loss in Output A}}{\text{Gain in Output B}}$. Shows the trade-off ratio between two goods in production.

32. What is required for a country to have a comparative advantage?

    A lower opportunity cost in producing a good. Must sacrifice less of other goods to produce this good.

33. Which country has the comparative advantage in coffee if its OC is lower?

    The country with the lower opportunity cost in coffee. Comparative advantage is determined by relative opportunity costs.

34. What role does specialization play in trade?

    It enhances efficiency and output. Focusing on comparative advantage increases overall productivity.

35. What happens to the PPF if resources increase?

    The PPF shifts outward. Greater resource availability expands production possibilities.

36. Which factor can shift the PPF inward?

    A decrease in available resources. Natural disasters, wars, or resource depletion reduce capacity.

37. How does opportunity cost influence comparative advantage?

    Lower opportunity cost gives comparative advantage. The basis for determining which good to specialize in.

38. How does opportunity cost relate to decision-making?

    It helps in choosing the next best alternative. Compares the value of alternatives when making economic choices.
