Suppose the price elasticity of demand for the market of mobile phones is 0.90.
If all mobile-phone companies simultaneously increased their prices, will total revenue in the industry increase or decrease?
If a single mobile-phone company increased its price, would you expect the company’s total revenue to increase or decrease? Explain.
Suppose that the price in the market is initially $10 and the quantity demanded is 100 units. If the price in this market increases by 10%, what will be the percentage change in the quantity demanded?

- Suppose you are in change of sales at a pharmaceutical company, and your firm has a new drug that causes bald men to grow hair. Assume that the company wants to earn as much revenue as possible from this drug. If the elasticity of demand for your companys product at the current price is 1.4, would you advise the company to raise the price, lower the price, or to keep the price the same? What if the elasticity were 0.6? What if it were 1? Explain your answer.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_forwardUsing the midpoint formula for calculating the elasticity of supply, if the price of a good rose from $95 to $105, what would be the elasticity of supply if the quantity supplied changed from a. 38 to 42? b. 78 to 82? c. 54 to 66?arrow_forward
- Suppose 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_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 that your demand schedule for DVDs is as follows: Price Quantity Demanded (income = 10,000) Quantity Demanded (income = 12,000) 8 40 DVDs 50 DVDs 10 32 45 12 24 30 14 16 20 16 8 12 a. Use the midpoint method to calculate your price elasticity of demand as the price of DVDs increases from 8 to 10 if (i) your income is 10,000 and (ii) your income is 12,000. b. Calculate your income elasticity of demand as your income increases from 10,000 to 12,000 if (i) the price is 12 and (ii) the price is 16.arrow_forward
- Although we could describe both the cross-priceelasticity of demand between paper coffee cupsand plastic coffee lids and the cross-price elasticityof demand between sugar and artificial sweeteners as highly elastic, the first cross-price elasticityis negative and the second is positive. What is thereason for this?arrow_forwardExplain in your own words what information the income elasticity of demand provides. If a good is an inferior good, what will the sign of the income elasticity of demand be? Explain. If a good is a normal good, what will the sign of the income elasticity of demand be? Explain. Suppose consumers experience an increase in income. If the income elasticity of demand is equal to 1.6, what will happen to the demand for new cars? As a result of the increase in income, holding other things constant, what will happen to new car prices. Suppose consumers experience an increase in income. If the income elasticity of demand is equal to -1.6, what will happen to the demand for used cars? As a result, holding other things constant, what will happen to the price of used cars?arrow_forwardA: Suppose the initial demand at the price of $10 was 100. When the price rises to $12, the demand drops to 30. Find the price elasticity of the demand. Is the demand elastic or inelastic in this price range? Will the revenue increase or decrease as the result of this price change? Justify your answer. B:. Using calculus, calculate the price elasticity of the following demand functions: D(p)=10-2ln(p) and D(p)=7p -3 . C: Suppose now that the demand is D(p)=12-3p. At what price is the revenue maximized? What is the maximum revenue? What is the price elasticity of demand at this price?arrow_forward
- Suppose that the demand curve for a product is given by Qdx=100-2Px+aPy where Px = £20, where Py = £20 is the price of another product, and where a is 0. Calculate the demand for good X in this market at the current price level. How much revenue would the firm make? If the firm wishes to increase total revenue, would it need to increase or decrease the current price of good X? Calculate the cross-price point elasticity between goods X and Y at the current price level. Are the goods complements or substitutes?arrow_forwardQ.3. Suppose the own price elasticity of demand for good X is −5, its income elasticity is 2, its advertising elasticity is 3, and the cross-price elasticity of demand between it and good Y is 6. Determine how much the consumption of this good will change if: Instructions: Enter your responses as percentages. If you are entering a negative number, be sure to use a (−) sign. a. The price of good X decreases by 4 percent. percent b. The price of good Y increases by 7 percent. percent c. Advertising decreases by 3 percent. percent d. Income increases by 2 percent. percentarrow_forwardSuppose household annual demand for gasoline follows the equation QD = 2000 – 500P + 25I where P is the price of a gallon of gasoline and I is household income in 1000s of dollars. Suppose that P = 3 and I = 60. What quantity of gasoline will households demand at this price and income level? __________ What is the income elasticity of demand for gasoline at this price, income, and quantity level? __________ What happens to the income elasticity of gasoline demand if I rises from 60 to 100? It _____________ (rises/falls) to ______________. Does this change in elasticity make gasoline buying more or less sensitive to income changes? __________arrow_forward
