- In an attempt to increase revenues and profits, a firm is considering a 4 percent increase in price and an 11 percent increase in advertising. If the price elasticity of demand is 1.5 and the advertising elasticity of demand is +0.6, would you expect an increase or decrease in total revenues?arrow_forwardIf the midpoint on a straight-line demand curve is at a price of $7, what can we say about the elasticity of demand for a price change from $12 to $10? What about from $6 to $4?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
- (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_forwardProve that price elasticity of demand is not the same as the slope of a demand curve.arrow_forwardWhat are the major determinants of a products price elasticity of demand? Studies indicate that the demand for Florida oranges, Bayer aspirin, watermelons, and airfares to Europe are elastic. Why?arrow_forward
- Suppose Erin, the owner-manager of a local hotel projects the following demand for her rooms: a. Calculate the price elasticity of demand between 90 and 110. b. Is the price elasticity of demand between 90 and 110 elastic, unit elastic, or inelastic? c. Will Erins total revenue rise if she increases the price from 90 to 110? d. Calculate the price elasticity of demand between 110 and 130. e. Is the price elasticity of demand between 110 and 130 elastic, unit elastic, or inelastic? f. Will Erins total revenue rise if she increases the price from 110 to 130?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_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_forward
- Consider the following supply schedule: What is the price elasticity of supply between a. P = 10 and P = 8? b. P = 8 and P = 6? c. P = 6 and P = 4? d. P = 4 and P = 2? e. P = 2 and P = 0?arrow_forwardThe 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_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_forward
