Minimum Price for Alcohol in GB

http://www.bbc.co.uk/news/health-20515918 describes a proposal to put a minimum price on the retail price of a unit of alcohol in Great Britain. A study estimates that setting the minimum @ 45 p would reduce consumption by 4.3%. Also see http://www.huffingtonpost.co.uk/2012/11/28/theresa-may-to-announce-m_n_2202231.htmland http://www.marketplace.org/topics/world/british-government-wants-booze-price-hike.

A colleague wonders why GB is thinking about setting a minimum price instead of imposing or increasing a tax. Using higher taxes will also reduce the quantity demanded and would have the additional benefit of generating tax revenue. Using a minimum price has the advantage of targeting cheap alcohol, the consumption of which imposes more externalities than sipping brandy.

Rationing water in CA

This article from CNN reports that Gov. Brown calls for 'voluntary "20% conservation of our water use"'. It might be a good way to introduce rationing in courses. It could also spur discussion about why we typically rely on governments instead of free markets to supply water in most localities. Finally, it might be the basis for a good question: "What percentage price increase reduces water usage by 20%?"

Amazon increases the price for Prime

This article from the WSJ reports that Amazon is increasing the price of its Prime service from $79/year to $99/year. It is a good introduction to pricing, elasticity, and behavioral economics.

If the does not work, conduct a Google search on the title.

SUMMARY: Amazon plans to raise the rate for Prime membership to $99 a year from $79, the first price increase for the shipping and video-streaming service. The Seattle retailer said the 25% increase was needed to offset rising delivery and content-acquisition costs. As a result of the 25% price increase, "analysts said they expect fewer than 10% of the more than 20 million Prime members to drop their accounts."

CLASSROOM APPLICATION: Instructors can use the article to present the price elasticity of demand for Amazon Prime services, and also present the reason Amazon is increasing the price of the service.

QUESTIONS: 
1. (Advanced) According to the data presented in the article, what is the possible range of the price elasticity of demand for Amazon Prime?

2. (Introductory) Why is Amazon raising the price of its Prime service? Is it an increase in cost of providing the service or an increase in demand?

3. (Advanced) Under what condition would it be profitable for Amazon to price Prime at below the marginal cost of providing the service?

Price elasticity and ebooks

This article in the New Yorker reports that Amazon wants Hachette to reduce the prices for most ebooks it offers through Amazon and to increase the percentage of the price paid to authors from 25% to 35%. It is a great introduction to elasticity and pricing.

1. What is the arc-price elasticity if Amazon is correct when it wrote, "for every copy an e-book would sell at $14.99, it would sell 1.74 copies if priced at $9.99." 
2. Would revenue rise if Hachette cuts price from $14.99 to $9.99?
3. Who gains and who loses if price decreases from $14.99 to $9.99, the percentage retained by the author increases from 25% to 35%, Hachette's share falls from 45% to 35%, and Amazon's share remains constant at 30%? Assume that the marginal cost of an additional download of an ebook is $0.
4. Are the interests of Hachette, the authors, and Amazon aligned over what price to charge?
5. Are the interests of Hachett, the authors, and Amazon aligned over how to share revenues and (fixed) costs?
6. Why does Amazon advocate that some books be sold at prices in excess of $9.99?

Competition, strategies, and UPS's profit margin

This article from the WSJ reports that UPS has seen its profit margin decrease as e-business deliveries quadrupled. Some juicy quotes follow.

"Because of the ubiquity of free shipping, fierce competition from other delivery services and Amazon's power to drive down shipping costs as it gets even more enormous, UPS's average revenue on each Internet-related package it handles is dropping.

"UPS is under more pressure than FedEx Corp. and the U.S. Postal Service because UPS is the biggest e-commerce carrier and its two rivals dived into the business later with narrower strategies.

TOPICS: Innovation
SUMMARY: Google and Cablevision Systems are preparing new cellphone services that would turn the wireless industry's business model on its head, increasing pressure on companies already dealing with a price war. Related article: Cablevision's service, dubbed "Freewheel," will take advantage of the 1.1 million Wi-Fi hot spots the company has deployed in its greater New York service area since 2007.
CLASSROOM APPLICATION: Students can conjecture about the effect of the introduction of wireless service using Wi-Fi hot spots and cellular connections on the price of wireless service.
QUESTIONS: 
1. (Advanced) Distinguish the types of consumers who use 'Wi-Fi only,' 'Wi-Fi first,' and cellular wireless service. Conjecture on the price elasticities of demand for these different types. How would the consumer price elasticities of demand affect the equilibrium prices of these services?

2. (Introductory) How would the increasing popularity of 'Wi-Fi only' service affect the equilibrium prices of cellular service?

3. (Advanced) What are "sunk costs"? Are the costs of constructing cellular networks fixed and sunk? How do large fixed and sunk costs required to offer a service affect entry into an industry? How does limited entry affect equilibrium prices?

4. (Advanced) What is "normal economic profit"? Does the limited entry resulting from large fixed costs of entry imply that the firms operating in an industry earn above normal economic profit? Are cellular companies earning above normal economic profit?

TOPICS: International Trade

SUMMARY: High-level talks to wrap up a 12-nation Pacific trade pact have put one set of Hawaii's locals on edge: Maui's sugar cane operation, which is concerned that U.S. concessions to growers in other countries could hurt its business model. "The proposed Trans-Pacific Partnership appears all but certain to allow more sugar imports into the U.S. from some countries, putting pressure on farmers and potentially disrupting a carefully balanced government program that protects the industry, American growers say."

CLASSROOM APPLICATION: Students can examine the winners and losers of reducing trade barriers. With reduced U.S. trade barriers for sugar imports, losers could include the U.S. sugar farmers and processors, while winners could include American confectioners and other sweetener consumers. Students can also examine the tradeoff to U.S. politicians of reducing trade barriers. "As with several thorny issues in the Pacific talks, U.S. trade representative Mike Froman is seeking to strike a delicate balance on sugar, opening American markets to more foreign competition without disrupting a politically entrenched program protecting the industry, according to people following the talks."

QUESTIONS: 
1. (Introductory) What is the effect of the U.S. lowering barriers to sugar imports on the price of sugar in the U.S.?

2. (Advanced) In the U.S. who is harmed by reduced barriers to sugar imports? Who benefits by the reduced barriers?

3. (Advanced) What is the effect of U.S. increasing the Australian quota on the Mexican sugar industry?

TOPICS: Opportunity Costs

SUMMARY: There are new ways to look at the value of time, allowing people to make more thoughtful choices.

CLASSROOM APPLICATION: Instructors can use this Work & Family column to introduce issues involved in determining opportunity cost of time. They can also use the column to highlight the types of mistakes people make in time-use decisions.

QUESTIONS: 
1. (Advanced) Why does putting a dollar value on your time require more than dividing your pay by hours worked?

2. (Advanced) What are examples of inconsistencies in decisions about the use of time?

3. (Introductory) Should people factor opportunity cost into their time-use decisions?

Who benefits from subsidies to college students?

This article in the WSJ reports that the primary beneficiaries of subsidies to college tuition are the colleges. It might be a good example to illustrate the incidence of a subsidy for a good with an very inelastic demand.

TOPICS: Education

SUMMARY: A new Fed study shows that colleges pocket most student subsidies. The New York Fed staff paper is available at http://www.newyorkfed.org/research/staff_reports/sr733.pdf.

CLASSROOM APPLICATION: Students can evaluate the effect of grants for higher education on the tuition by using supply and demand, students can evaluate the effect of subsidy on the demand for higher education and ultimately the equilibrium price. Investigating the issue in greater detail, students can examine the relationship between the price elasticities of supply and demand and the effect of federal student aid on equilibrium tuition rates.

QUESTIONS: 
1. (Advanced) In a perfectly competitive market, what is the effect of a subsidy for purchasing a good on the price of the good? How does the magnitude of the price change depend on the price elasticities of supply and demand?

2. (Advanced) What is the effect of federal subsidies to higher education on tuition?

3. (Introductory) Should the federal government subsidize higher education? Should it cap tuition increases set by colleges and universities?

Price controls and medical care

This opinion in the WSJ states that access to medical care is better under private insurance than under government programs such as Medicaid. Here are some questions to consider.

1. Why would "55% of doctors in major metropolitan areas refuse new Medicaid patients"?
2. Why would "29% of Medicare beneficiaries who were looking for a primary-care doctor in 2008 already had a problem finding one"?
3. Why would "patients with private insurance have better outcomes than similar patients on government insurance"?
