7. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.37 Productive Efficiency: Making Stuff Right  Productive efficiency occurs when a firm produces at the lowest possible cost per unit.  Competition ensures that firms produce at the lowest possible cost per unit.

8. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.38 Allocative Efficiency: Making the Right Stuff  Allocative efficiency occurs when firms produce the output that is most valued by consumers.  Competition among sellers encourage producers to supply more of what consumers value the most.

9. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.39 Distinguish between allocative efficiency and productive efficiency. Checkpoint: pg. 180  Productive efficiency occurs when the firm produces at the lowest possible cost per unit.  Allocative efficiency occurs when firms produce the output that is most valued by consumers.

10. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.310 Disequilibrium  Disequilibrium—a mismatch between quantity demanded and quantity supplied as the market seeks equilibrium  Disequilibrium is usually a temporary condition when the plans of buyers do not match the plans of sellers.

11. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.311 Other Sources of Disequilibrium  Government intervention in the market  Sometimes, as a result of government intervention in markets, disequilibrium can last a while.  Sometimes the market takes a while to adjust  New products  Sudden change in demand or supply

12. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.312 Disequilibrium  A price floor is a minimum selling price that is above the equilibrium price.  To have an impact, a price floor must be set above the equilibrium price.  The Minimum wage is a price floor in the market for labor.  The government sets the minimum labor price and no one is allowed to pay less.

13. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.313 Price Floor  If a price floor is established above the equilibrium price, a permanent surplus results.

14. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.314 Price Floor  A price floor established at or below the equilibrium price has no effect.

15. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.315 Disequilibrium  A price ceiling is a maximum selling price that is below the equilibrium.  To have an impact, a price ceiling must be set below the equilibrium price.  The good intensions of government officials create shortages and surpluses that often are economically wasteful.

16. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.316 Price Ceiling  A price ceiling is established below the equilibrium price, a permanent shortage will result.

17. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.317 Price Ceiling  A price ceiling is established at or above the equilibrium price, has no effect.

18. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.318 What happens when governments impose price floors and price ceilings?  When governments impose price floors or ceilings:  market prices are distorted and interfere with the market’s ability to allocate resources efficiently.  This results in disequilibrium of the market. Checkpoint: pg. 181

19. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.319 Consumer Surplus  Consumer surplus - is the difference between the total amount consumers would have been willing and able to pay for that quantity and the total amount they actually do pay.

21. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.321 An Application of Consumer Surplus: Free Medical Care  Certain Americans are provided government- subsidized medical care.  When something is provided for free, people consume it until their marginal benefit is zero.

22. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.322 How do consumers benefit from market exchange?  Consumers benefit from market exchange by receiving the goods they demand and want at a price they are willing to pay.  When there is a consumer surplus, consumers pay lower prices than they would have originally been willing to pay.
