- (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_forwardIf automobiles and gasoline are complements, then their cross-elasticity coefficient is a. strictly greater than 1. b. positive. c. equal to zero. d. negative.arrow_forwardProve that price elasticity of demand is not the same as the slope of a demand curve.arrow_forward
- The price elasticity of demand for personal computers is estimated to be 2.2. If the price of personal computers declines by 20 percent, what will be the expected percentage increase in the quantity of computers sold?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_forwardSuppose a straight-line downward-sloping demand curve shifts rightward. 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_forward
- Estimates presented in Exhibit 5 show that Android users have a higher price elasticity of demand for apps in the Google Play Store than do iPhone users in the Apple App Store. Why might Android users tend to be more sensitive to app prices than iPhone users? What categories or types of apps (for example, games/social media) do you think have the highest price elasticities?arrow_forwardIf bus travel is an inferior good, its income elasticity of demand is a. strictly greater than 1. b. positive. c. equal to zero. d. negative.arrow_forwardSuppose you learned that the price elasticity of demand for wheat is 0.7 between the current price for wheat and a price 2 higher per bushel. Do you think that farmers collectively would try to reduce the supply of wheat and drive the price up 2 higher per bushel? Explain your answer. Assuming that they would try to reduce supply, what problems might they have in actually doing so?arrow_forward
