Production Possibilities Curve The PPC illustrateswhat is possible in termsof production with given resources and technology • Assumptions: • Fixed endowment of economic resources • Fixed technology • Resources fully utilized
Digression on technology • Technology is “applied know how.” • “A sharp knife is better than a dull knife.” • Specialization is the inevitable consequence of technology.
Feasible zone The PPC • U is an inefficient point • I is an impossible point A 200 B I 175 C 130 Defense goods U F 0 75 125 160 Nondefense goods
Shifts of the PPC • 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 0 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 qualityof human resources Defense goods 0 Nondefense goods
Why is the PPC bow-shaped? 1MOC is defined as marginal opportunity cost.
