Which model illustrates the trade-offs facing an economy that produces only two goods?

• A. Free market
• B. PPC/PPF
• C. Centrally planned economy
• D. Law of Demand

Answer: (B)

Trade-offs when an economy can produce only two goods are captured by the production possibilities frontier (PPF). With limited resources and given technology, choosing more of one good means giving up some of the other, and this trade-off is shown graphically as a curve that links all the efficient production combinations of the two goods. On the frontier, each point represents a fully efficient use of resources, where any gain in one good comes at the expense of the other. Points inside the curve show underutilized resources, while points outside aren’t attainable with current resources and technology. The slope of the curve tells you the opportunity cost: how much of one good you must give up to produce a little more of the other. If the curve bows outward, opportunity costs rise as you produce more of one good, reflecting resources that are better suited to producing one good than the other. If it were a straight line, opportunity costs would be constant. Other options describe different ideas (a market system, a planned economy, or how price affects demand) but don’t specifically illustrate the trade-offs between two goods with a fixed set of resources and tech that the two-good scenario demonstrates.
