Is the price elasticity of demand higher, lower, or the same between any two prices on the new (higher) demand curve than on the old (lower) demand curve?arrow_forwardIf the elasticity of demand for hamburgers equals 21.5 and the quantity demanded equals 40,000, predict what will happen to the quantity demanded of hamburgers when the price increases by 10 percent. If the price falls by 5 percent, what will happen?arrow_forwardPrice elasticity of demand tends to be larger in the long run than in the short run. Which of the following is a reason that this statement is true? a. Over time, peoples incomes rise. b. If price rises, over time, producers will be able to offer more substitutes. c.

- For each of the following, identify where demand is elastic, inelastic, perfectly elastic, perfectly inelastic, or unit elastic: a. Price rises by 10 percent, and quantity demanded falls by 2 percent. b. Price falls by 5 percent, and quantity demanded rises by 4 percent. c. Price falls by 6 percent, and quantity demanded does not change. d. Price rises by 2 percent, and quantity demanded falls by 1 percent.arrow_forward(Calculating Price Elasticity of Demand) Suppose that 50 units of a good are demanded at a price of Si per unit. A reduction in price to $0.20 results in an increase in quantity demanded to 70 units. Using the midpoint formula, show that these data yield a price elasticity of 0.25. By what percentage would a 10 percent rise in the price reduce the quantity demanded, assuming price elasticity remains constant along the demand curve?arrow_forwardThe Stopdecay Company sells an electric toothbrush for $25. Its sales have averaged 8,000 units per month over the past year. Recently, its closest competitor, Decayfigh ter, reduced the price of its electric toothbrush from $35 to $30. As a result, Stopde cays sales declined by 1,500 units per month. What is the arc cross elasticity of demand between Stopdecays toothbrush and Decayfighters toothbrush? What does this indicate about the relationship between the two products? If Stopdecay knows that the arc price elasticity of demand for its toothbrush is 1.5, what price would Stopdecay have to charge to sell the same number of units as it did before the Decayfighter price cut? Assume that Decayfighter holds the price of its toothbrush constant at $30. What is Stopdecays average monthly total revenue from the sale of electric toothbrushes before and after the price change determined in part (b)? Is the result in part (c) necessarily desirable? What other factors would have to be taken into consideration?arrow_forward
