Shifts of the PPC Defense goods Nondefense goods PPC could shift right due to: Improved technology Population growth Improved education and training Discovery of new natural resources Growth of the capital stock Defense goods Nondefense goods
Shifts of the PPC, part II PPC could shift left due to: Depletion of nonrenewable resources. Destruction of the capital stock resulting from war or natural disaster. Failure to replace worn-out capital Deteriorating quality of human resources Defense goods Nondefense goods
