Three Movements of the PPC

1. Inside the PPC: this occurs when resources are unemployed or underemployed 
2. Along the PPC
3. Shifts of the PPC

What Causes the PPC to shift?

• Technological Changes (Shift Outside/Right of the Curve)
• Change in Resources (More Resources = Shift Outside/Right) (Less Labor = Shift Inside/Left)
•   Economic Growth (Shift Outside/Right of the Curve)
• Natural Disasters/War/Famine (Shift Inside/Left of the Curve)
• Change in Labor Force (Less Labor = Shift Inside/Left) (More Labor = Shift Outside/Right) More Education & Training (Shift Outside/Right of the Curve)
