To calculate elasticity along a demand or supply curve economists use the average percent
change in both quantity and price. This is called the Midpoint Method for Elasticity, and is
represented in the
following

- . Gas Prices and Public Transit Ridership. Consider the effect of higher gasoline prices on public transit ridership. The initial price of public transit is $2.00 per ride and the initial ridership is 100,000 people per day. Suppose the elasticity of transit ridership with respect to the price of gasoline is +0.667 or (2/3) and the price of gasoline increases by 30 percent? A. Assume the price of public transit remains at $2. Use a graph to show the effect of the increase in the gas price on transit ridership. B. Suppose the transit authority matches the increase in the price of gasoline, increase the transit fare by 30 percent. The price elasticity of demand for transit ridership is 0.333 (or 1/3). Use your graph to show the combined effect of the gas tax and higher transit fare. C. Explain why the net change in transit ridership is positive or negative.arrow_forwardApple, the consumer electronics giant, on Tuesday rolled out new versions of its popular iPod music player. CEO Steve Jobs also unveiled cheaper models of its Touch music player, a touchscreen-only device. An 8-gigabyte version now costs $229, down from $299. A 32-gigabyte model costs $399, down from $499. If the cross elasticity of demand is positive between iPods and iPhones, then the two goods are A. complements. B. substitutes. C. normal goods. D. inferior goods.arrow_forwardEvidence suggests that the cross elasticity of demand between private and public transport, although positive, is low. Therefore it follows that: A fall in the demand for private transport would cause a small rise in the price of public transport A fall in the demand for private transport would cause a small rise in the demand for public transport The effects cannot be determined from the information given A rise in the price of private transport would cause a small rise in the demand for public transport A fall in the price of private transport would cause slight rise in the demand for public transport Some other answerarrow_forward
- How elastic is the demand for student parking at college campuses? The answer to this question likely varies based on the profile of the institution, but we are going to explore a particular example. Let’s consider a community college campus where all of the students commute to class. Required courses are spread throughout the day and the evening, and most of the classes require classroom attendance (rather than online participation). There is a reasonable public transportation system with busses coming to and leaving campus from several lines, but the majority of students drive to campus. A student parking permit costs $40 per term. As the parking lots become increasingly congested, the college considers raising the price of the parking passes in hopes that it will encourage more students to carpool or to take the bus. If the college increases the price of a parking permit from $40 to $48, how many fewer students will buy parking permits? If you think that the change in price…arrow_forwardLabel demand as elastic, unit elastic, or inelastic for each scenario. Use the midpoint method when applicable to calculate the price elasticity of demand Contain Yourself!, a plastic container company, raises the price of its signature Lunchbox container from $3.00 to $4.00. As a result, the quantity sold drops from 20,000 to 15,000. Economists working for the United States have determined that the elasticity of demand for gasoline is 0.5 Capital Metro decides to increase bus fare rates from $2.00 to $2.21. Consequently, the number of passengers who decide to take the bus in Austin drops from an average of 70,000 riders a day to an average of 61,000 riders a day. Answer Bank perfectly elastic elastic unit elastic inelastic perfectly inelasticarrow_forwardOnline the timing and tailoring of prices to specific products is the key to successful pricing in online markets. And " Thanks to the ready availability of data in online markets, a pricing manager can easily approximate the elasticity of demands for the different products it sells online." Assuming a 10 percent decrease in price increases sales by 30 percent, calculate the price elasticity of demand? If the wholesale price of the online product is $50 and sells at a price comparison site that charges $0.50 per click and boasts a conversation rate of 5 percent ( an average of 20 percent clicks are needed to generate sale), the incremental cost of each sale is $50. What price should you change for the product? What is the markup? B) . The authors assert that price sensitivity is affected by (1) product cycle, and (2) number of competitors. In fact, " When the number of competing sellers doubles, a firm's elasticity of demand is expected to double ( you should be able to verify this…arrow_forward

The railroad argued that declining revenues made this rate increase essential. Opponents of the rate increase contended that the railroad's revenues would fall because of the rate hike. It can be concluded that: both groups felt that the demand was elastic but for different reasons. both groups felt that the demand was inelastic but for different reasons. the railroad felt that the demand for passenger service was inelastic and opponents of the rate increase felt it was elastic. the railroad felt that the demand for passenger service was elastic and opponents of the rate increase felt it was inelastic.arrow_forward
