Define production possibility curve.

The Production Possibility Curve (PPC) is a graphical representation showing the maximum possible combinations of two goods that an economy can produce with its given resources and technology, assuming full employment and efficient use of resources. It illustrates the concept of scarcity, choice, and opportunity cost.

Key features of PPC:

• Points on the curve represent efficient production (full utilization of resources).
• Points inside the curve indicate inefficient use of resources (underemployment).
• Points outside the curve are unattainable with current resources and technology.
• The downward slope reflects the trade-off between producing two goods (opportunity cost).
• A rightward shift of the curve indicates economic growth (increased resources or technological advancement).
