What does increasing marginal opportunity costs mean in the context of a production possibilities frontier (PPF)?

• A. Resources are perfectly adaptable to the production of all goods.
• B. Producing each additional unit of a good requires giving up increasingly larger amounts of the other good.
• C. The opportunity cost of producing a good remains constant as more of it is produced.
• D. The PPF is a straight line, indicating equal trade-offs between goods.

Answer: (B)

Verified step by step guidance

1. Understand that the Production Possibilities Frontier (PPF) represents the maximum combinations of two goods that an economy can produce given its resources and technology.
2. Recognize that 'increasing marginal opportunity costs' means that as you produce more of one good, the opportunity cost of producing additional units of that good rises.
3. This happens because resources are not perfectly adaptable; some resources are better suited for producing one good than the other, so shifting production leads to less efficient use of resources.
4. Graphically, this concept is shown by a PPF that is concave (bowed out) from the origin, indicating that producing each additional unit of one good requires giving up increasingly larger amounts of the other good.
5. Contrast this with a straight-line PPF, which would imply constant opportunity costs and perfectly adaptable resources, meaning the trade-off between goods remains the same regardless of the production level.
