Operating inside the PPC signals inefficiency

Steps:

• Recall that the production possibility curve (PPC) represents maximum output with full resource use and technology.
• Points on the PPC show efficient production at full capacity.
• Points inside the PPC indicate underutilization, such as unemployment or idle resources.
• This position implies output below potential, affecting growth dynamics.

Why C is correct:

• Inside the PPC means resources are not fully employed, leading to output below potential and thus a low level of output growth, per the definition of PPC as efficient frontier.

Why the others are wrong:

• A: Self-sufficiency relates to trade dependence, not PPC position.
• B: Competitiveness involves market performance abroad, unrelated to internal efficiency.
• D: Economic growth rate requires time-series data, not a single PPC point.

Final answer: C
