CHAPTER 2 THE BASICS OF SUPPLY AND DEMAND QUESTIONS FOR REVIEW 1. Suppose that unusually hot weather causes the demand curve for ice cream to shift to the right. Why will the price of ice cream rise to a new market-clearing level? Assume the supply curve is fixed. The unusually hot weather will cause a rightward shift in the demand curve, creating short-run excess demand at the current price. Consumers will begin to bid against each other for the ice cream, putting upward pressure on the price. The price of ice cream will rise until the quantity demanded and the quantity supplied are equal. [pic] Figure 2.1 2. Use supply and demand curves to illustrate how each of the following events would affect the price…show more content…
However, in the long run all firms can increase their scale of production and thus have a larger long-run price elasticity. 6. Why do long-run elasticities of demand differ from short-run elasticities? Consider two goods: paper towels and televisions. Which is a durable good? Would you expect the price elasticity of demand for paper towels to be larger in the short-run or in the long-run? Why? What about the price elasticity of demand for televisions? Long-run and short-run elasticities differ based on how rapidly consumers respond to price changes and how many substitutes are available. If the price of paper towels, a non-durable good, were to increase, consumers might react only minimally in the short run. In the long run, however, demand for paper towels would be more elastic as new substitutes entered the market (such as sponges or kitchen towels). In contrast, the quantity demanded of durable goods, such as televisions, might change dramatically in the short run following a price change. For example, the initial result of a price increase for televisions would cause consumers to delay purchases because durable goods are built to last longer. Eventually consumers must replace their televisions as they wear out or become obsolete, and therefore, we expect the demand for durables to be more inelastic in the long run. 7. Are the following statements true or false? Explain your answer. a. The elasticity of demand is
