A city Has built a bridge over a river and it decides to charge a toll to everyone who crosses. For one year, the city charges a variety of different tools told and records information on how many drivers across the bridge. The city thus gathers information about elasticity of demand. If the city wishes to raise as much revenue as possible from the tolls, where will the city decide to charge a toll: in the inelastic portion of the demand curve, the elastic portion of the demand curve, or the unit elastic portion? Explain.

take a moment to see if you can figure out which of the following products have elastic demand and which have inelastic demand. It may be helpful to remember that when the buyer is insensitive to price, demand is inelastic.

You decide to take advantage of this influx by starting a gourmet take-away food store. Assume that these DINKs in your neighbourhood are your only potential customers.You know that the price elasticity of demand for your food from DINKs is 0.5, and their income elasticity of demand is 1.5.From the standpoint of the quantity that you sell, explain which of the following changes would concern you most.First, the number of DINKs in your neighbourhood falls by 10 percent.Second, the average income of DINKs falls by 5 percent.arrow_forwardA minor league baseball team raised the average price of its tickets from $8 to $8.90 and found that average attendance at its games dropped from 5,200 to 4,700.

- 1. As a transit planner for the city of Miami, you must predict how many people ride the Miami Metrorail and how much money is generated from train fares. According to a recent study, the short-run elasticity of demand for Metrorail is 0.62 and the long- run elasticity is 1.59. The current ridership is 50,000 people per day. Suppose the city commission decides to increase fares by 10%. Predict the changes in train ridership over a one-month period and a five-year period. ANS: b. Over the one-month period, will total revenue increase or decrease? What will happen in the five-year period? ANSarrow_forwardConsider the following pairs of goods.

Epi-pens are used to quickly inject epinephrine into the body in the event of a severe allergic reaction. Many Americans require Epi-pens due to potentially life-threatening allergies. Using the concept of elasticity, explain why the government would likely not impose a tax on the market for Epi-pens. Suppose the government believes the price of Epi-pens is too high, so they impose a price control on the market. Would the government use a price floor or a price ceiling in this situation? What effect would the chosen price control have on the market. Suppose that the number of adults developing severe allergies increases. At the same time the patent for Epi-pens expires, allowing new producers of Epi-pens to enter the market. Explain what will happen to the equilibrium price and quantity of Epi-pens.arrow_forward
- Suppose a movie theater determines it can charge different prices to patrons who go to weekday matinees and people who attend evening and weekend shows. The movie theater's goal is to increase total revenue. See Hint The price elasticity of demand for weekend and evening patrons is -0.50, and the price elasticity of demand for matinee moviegoers is -2.80. Based on the price elasticity of demand for each group of people, how should the movie theater adjust its prices? Choose one: O A. Raise the price for matinee moviegoers, and keep the price the same for weekend and evening patrons. O B. Lower the price for matinee moviegoers, and raise the price for weekend and evening patrons. O C. Lower the price for matinee moviegoers, and keep the price the same for weekend and evening patrons. O D. Raise the price for matinee moviegoers, and lower the price for weekend and evening patrons.arrow_forwardThe price elasticity of demand for beer among young adults (age 18 to 24) is about 1.30, and the number of highway deaths is roughly proportional to the group’s beer consumption.
