Summary
The Production Possibility Frontier (PPF) illustrates the maximum productive potential of an economy, showing efficient and inefficient resource allocation, possible and unattainable production, and opportunity cost. It also represents economic growth and decline, and distinguishes between capital and consumer goods.
- Production Possibility Curve (PPC) — a graphical representation of the maximum combination of goods and services produced in an economy per period. Example: A PPC shows the trade-off between producing textbooks and computers.
- Opportunity Cost — the cost of forgoing the next best alternative when making a decision. Example: Moving from point B to A on the PPC to produce more textbooks means giving up the production of computers.
- Economic Growth — an increase in the productive potential of an economy, shown by a rightward shift of the PPC. Example: Investment in capital goods can lead to potential growth.
- Efficiency — using resources in such a way that maximizes the production of goods and services. Example: Operating on the PPC indicates full employment and efficiency.
- Capital Goods — goods used to produce other goods, significant for productivity and economic growth. Example: Machinery and equipment that help increase future production.

Key Definitions to Remember
- Production Possibility Curve (PPC)
- Opportunity Cost
- Economic Growth
- Efficiency
- Capital Goods
Common Confusions
- Confusing actual growth with potential growth
- Misunderstanding the difference between shifts and movements along the PPC
Typical Exam Questions
- What does a point inside the PPC indicate? It indicates underemployment of resources.
- How is opportunity cost represented on a PPC? By the slope of the curve, showing trade-offs between two goods.
- What causes a shift in the PPC? Changes in resource availability or technology.
What Examiners Usually Test
- Understanding of opportunity cost and its representation on the PPC
- Ability to explain shifts versus movements along the PPC
- Distinction between capital and consumer goods and their impact on growth
