Microeconomics
A PPC diagram showing different levels of production efficiency and economic feasibility using combinations of consumer and capital goods.

Production Possibility Curve (PPC): Shows the maximum combinations of consumer and capital goods that an economy can produce using all available resources efficiently.
Point A: Inefficient use of resources — attainable but not desirable.
Point B: Efficient use of all resources — the economy is operating at full capacity.
Point C: Unattainable with current resources — requires economic growth to reach.
Point A lies inside the PPC and represents underutilization of resources — the economy is not producing at full efficiency.
Point B lies on the PPC curve and represents productive efficiency — the economy is maximizing its use of available resources.
Point C lies outside the PPC and is currently unattainable with the existing resource base and technology.
Economic growth or technological advancement would be required to shift the PPC outward and make point C attainable.
The PPC demonstrates opportunity cost: producing more of one type of good requires sacrificing the production of the other due to scarce resources.
