2. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.12 CHAPTER 6 Market Forces  How is market competition different from competition in sports and in games?  Why do car dealers usually locate together on the outskirts of town?  What’s the difference between making stuff right and making the right stuff?  Why do government efforts to keep rents low usually lead to a housing shortage?  Why do consumers benefit nearly as much from a low price as from a zero price?

7. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.17 Surplus Forces the Price Down  Surplus—at a given price, the amount by which quantity supplied exceeds quantity demanded.  As long as quantity supplied exceeds quantity demanded, the surplus forces the price lower.

8. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.18 Shortage Forces the Price Up  Shortage—at a given price, the amount by which quantity demanded exceeds quantity supplied.  As long as quantity demanded and quantity supplied differ, this difference forces a price change.

9. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.19 Market Forces Lead to Equilibrium Price and Quantity  The equilibrium price, or market-clearing price, equates quantity demanded with quantity supplied.  Because there is no shortage and no surplus, there is no longer any pressure for the price to change.

10. © SOUTH-WESTERNCONTEMPORARY ECONOMICS: LESSON 6.110 Market Exchange  Markets answer the questions  What to produce  How to produce it  For whom to produce it
