Cost of Gain First What you are giving up Afterwards

A Production Possibility Curve (PPC) illustrates the maximum combinations of two goods or services that an economy can produce when all its resources are fully and efficiently employed, given the current state of technology. It demonstrates the concepts of scarcity, choice, and opportunity cost.

An outward shift of the PPC, as shown in Figure 1 (the right-hand graph with arrows pointing outwards), represents economic growth. This means the economy's productive capacity has increased, allowing it to produce more of both goods (e.g., guns and butter) than before, using the same amount of resources.

The main causes for an outward shift in the PPC are:

• Larger Labor Force: An increase in the quantity or quality of available labor (e.g., through population growth or improved education) allows for more goods and services to be produced.
• A New Resource: The discovery or availability of new natural resources expands the economy's productive potential.
• Technology: Advancements in technology improve production methods, making it possible to produce more output with the same inputs, or to produce new goods.
