Production Possibility Curve Represents Efficiency

Steps:

• Define the production possibility curve (PPC) as a graph showing maximum output combinations of two goods with fixed resources and technology.
• Recognize that points on the PPC indicate efficient production, where no more of one good can be produced without sacrificing the other.
• Link efficiency to full utilization: all available resources must be employed, and technology must be at its current best.
• Confirm by noting that any deviation from full use shifts points inside the curve, representing inefficiency.

Why A is correct:

• The PPC boundary embodies allocative and productive efficiency, per economic theory, requiring full employment of resources and full use of technology to achieve unattainable output elsewhere.

Why the others are wrong:

• B: Underutilized technology would place the economy inside the PPC, not on it.
• C: Unemployed resources mean production is inefficient, inside the PPC.
• D: Both underutilization and unemployment result in points inside the PPC, not on the curve.

Final answer: A
