- Your friend is a talented artist. She has no other employment options, she finds painting effortless, and the cost of materials is low enough that it can be safely ignored. Based on your analysis of market data, you estimate that elasticity of demand for her paintings is given in the displayed table. If your friend wants to maximize her income, what price do you advise her to charge for her paintings? Include a brief explanation. (If you think you can only determine a price range, as opposed to a precise price, give a price range.)Suppose (the numbers are loosely based on reality) that the tax on petrol is raised from 40 cents per litre to 60 cents per litre. The before-tax total cost of retailing petrol is $1.20 per litre. Assume that 100% of the tax is always passed through to consumers. After the increase in taxes, the quantity of petrol sold falls from 3,000,000 litres a day to 2,800,000 litres a day. Calculate the price elasticity of demand for petrol using the mid-point formula, based on the change in price due to the tax. Use three decimal places in your calculations. What are the implications for policymakers who want to raise revenue, when considering raising taxes on petrol?If the price of an airline ticket from DSM to ACY were to increase by 20%, from $250 to $300 roundtrip, while all other demand factors remain at their initial values, the quantity of rooms demanded at the Lakes from rooms per night to rooms per night. Because the cross-price elasticity of demand is , hotel rooms at the Lakes and airline trips between DSM and ACY are
- Taxicab fares in most cities are regulated. Several years ago, taxicab drivers in Boston obtained permission to raise their fares 10 percent, and the anticipated revenues would increase by about 10 percent as a result. They were disappointed, however, when the commissioner granted the 10% increase, revenues only increase about 5%. What can you infer about the elasticity of demand for taxi cab rides? What were taxicab drivers assuming about the elasticity of demand?Transport operators in Belize received permission to increase their fares 15percent, and they anticipated that revenues would increase by about 15percent. When the 15 percent increase was enacted revenues increased by only about 5 percent. What can you infer about the elasticity of demand for transportation? What were operators assuming about the elasticity of demand. Suppose a ticket to a Rolling Stones concert is $400 and at that price, the quantity of tickets demanded is 47,000 per concert. Using the midpoint method of calculating percentage changes, if the ticket price increases to $500 and the quantity demanded decreases to 46,000, what is the price elasticity of demand for Rolling Stones concert tickets? Referring to the above, which is greater -- the % change in quantity demanded or the % change in price? What will happen to total revenue (TR) when the price increases to $500? Briefly explain.
- If own-price elasticity of demand equals 0.3 in absolute value, then what percentagechange in price will result in a 6% decrease in quantity demanded?You are the manager of a gas station and your goal is to maximize profits. Based on your past experience, the elasticity of demand by Texans for a car wash is -4, while the elasticity of demand by non-Texans for a car was is -6. If you charge Texans $20 for a car wash, how much should you charge a man with Oklahoma license plates for a car wash? a. $20.00 b. $1.50 c. $18.00 d. $15.00Suppose you are in charge 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 company’s 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 with relevant diagrams

What is the price elasticity of demand for the Daily Newspaper when elasticity iscalculated using the midpoint method?b. What is the advantage of using the midpoint method?c. If the Daily Newspaper's only concern is to maximize total revenue, should it raise the price of a newspaper from Ghc1.00 to Ghc1.50? Why or why not?d. Suppose there is an increase in consumers' incomes. In the market for automobiles (a normal good), does this event cause an increase in demand or an increase in quantity demanded? Does this cause an increase in supply or an increase in quantity supplied? (Explain. NB: Explanation must not be more than half a page.)e.

(a) Obtain a formula for the price elasticity of demand E. E = (b) In one of the years the actual selling price was $365 per phone. What was the corresponding price elasticity of demand? (Round your answer to two decimal places.) E = Interpret your answer. The demand was going ---Select--- down up by about % per 1% increase in price at that price level.
