6. An example of a normal good is shoes such as Nike tennis shoes. The demand goes up as income goes up. An example of an inferior good is a bag of frozen french fries bought at the store. I can buy them for $.99 or less, but when I have more income, I can go to McDonalds or a local cafe to purchase them at a higher cost.


7. A price ceiling that is set below the equilibrium will cause a shortage because the quantity supplied is less than the quantity demanded thus creating a shortage of the good.
