The Production Possibilities Curve and Efficiency

Two Types of Efficiency Productive Efficiency- Products are being produced in the least costly way. This is any point ON the Production Possibilities Curve Allocative Efficiency- The products being produced are the ones most desired by society. This optimal point on the PPC depends on the desires of society. 2 Copyright ACDC Leadership 2015

Productive and Allocative Efficiency Which points are productively efficient? Which are allocatively efficient? 14 12 10 8 6 4 2 Productively Efficient combinations are A through D A B G Allocative Efficient combinations depend on the wants of society (What if this represents a country with no electricity?) Bikes C E F D 0 2 4 6 8 10 Computers 3

Why two types of efficiency? Is combination “A” efficient? Yes and No. It is productively efficient but it is not the combination society wants Size 20 running shoes A Size 10 running shoes

Shifting the Production Possibilities Curve

3 Shifters of the PPC Production Possibilities 4 Key Assumptions Revisited Only two goods can be produced Full employment of resources Fixed Resources (4 Factors) Fixed Technology What if there is a change? 3 Shifters of the PPC 1. Change in resource quantity or quality 2. Change in Technology 3. Change in Trade

Production Possibilities What happens if there is an increase in population? Computers Pizzas

Production Possibilities What happens if there is an increase in population? Computers Pizzas 11

Production Possibilities What if there is a technology improvement in pizza ovens Computers Pizzas 12

Production Possibilities What if there is a technology improvement in pizza ovens Computers Pizzas 13

Capital Goods and Future Growth Countries that produce more capital goods will have more growth in the future. Panama – Favors Consumer Goods Mexico – Favors Capital Goods Current PPC Future PPC Future PPC Capital Goods Current PPC Capital Goods Consumer goods Consumer goods Panama Mexico

PPC Practice Draw a PPC showing changes for each of the following: Pizza and Computers (3) 1. New computer making technology 2. Decrease in the demand for pizza 3. Mad cow disease kills 85% of cows Consumer goods and Capital Goods (4) 4. Destruction of power plants leads to severe electricity shortage 5. Faster computer hardware 6. Many workers unemployed 7. Significant increases in education

New computer making technology A shift only for computers Question #1 New computer making technology A shift only for computers Computers Pizzas 16

Question #2 Decrease in the demand for pizza The curve doesn’t shift! A change in demand doesn’t shift the curve Computers Pizzas 17

Mad cow disease kills 85% of cows A shift inward only for Pizza Question #3 Mad cow disease kills 85% of cows A shift inward only for Pizza Computers Pizzas 18

Question #4 Destruction of power plants Decrease in resources decrease production possibilities for both Capital Goods (Guns) Consumer Goods (Butter) 19

Question #5 Faster computer hardware Quality of a resource improves shifting the curve outward Capital Goods (Guns) Consumer Goods (Butter) 20

Question #6 Many workers unemployed The curve doesn’t shift! Unemployment is just a point inside the curve Capital Goods (Guns) Consumer Goods (Butter) 21

Question #7 Significant increases in education The quality of labor is improved. Curve shifts outward. Capital Goods (Guns) Consumer Goods (Butter) 22
