Describes the events leading up to the imposition of the London congestion charge. Views about the congestion charge, both pro and con, are presented. Also discusses, in general terms, the economics of traffic congestion, pointing out that an unregulated market for driving will not reach the social optimum. Contains sufficient data to estimate the deadweight loss in an unregulated market and the reduction of the deadweight loss due to the imposition of the congestion charge in 2003.

To provide a good illustration of how an unregulated market with negative externalities can lead to an overprovision of a good (in this case driving). Also, to show how an externality tax (in this case, London's congestion charge) can lead to an improvement in social welfare.

Fingerhut, based in Minnetonka, Minnesota, is a direct-marketing company that sells a smorgasbord of consumer goods through an array of specially targeted catalogs. In November 1996, an article in the Star Tribune, a major Minneapolis newspaper, drew attention to a class-action lawsuit pending against Fingerhut that suggests the firm made its profits by exploiting the poor. Several civil rights groups rallied around the suit and submitted amicus curiae in favor of the litigation. The case illustrates issues in ethics and management communication. Discussions focus on the constituencies. Is Fingerhut exploiting its customers or providing them with an affordable method of obtaining valued consumer goods on credit? Do retailers have a duty to offer products at reasonable prices? Are the high interest rates reasonable given the risk? What are the options: pawn shops, rent-to-own? What is the profile of the typical Fingerhut customer? Discussions also focus on the issues communicating to the constituencies. How much damage will the lawsuit do to Fingerhut's image as an ethical, socially conscious company? What communication strategies can the firm employ? Should it react to the lawsuit? What should it tell its employees?

Groupon, an online coupon company, was one of many companies that considered an initial public offering (IPO) during what might be a second technology/internet/social media IPO boom in 2011. Some companies chose to postpone their IPOs, while others took advantage of the media attention focussed on technology companies, and in particular, social media firms. Should investors hop on the tech IPO bandwagon, or hold off to better evaluate the long-term prospects of tech companies, and in particular social media companies? Would the valuation of Groupon justify an investment in IPO shares?

The case was researched from secondary sources, using Groupon's IPO filing information, news articles about the IPO and industry research sources, such as IBIS World.

This case is appropriate for an advanced undergraduate or MBA corporate finance or investment elective. Most introductory finance classes do not have the time to cover later chapters in a finance textbook, where information about IPOs is generally found. It could also be used at the end of a core finance course, where the instructor wanted to introduce this topic through a case study of a hard-to-value internet-based company to illustrate the difficulties in setting IPO prices. The case could also be used in an equity analysis class, an entrepreneurial finance class or an investment class, to spur discussion about valuing an internet company and choosing appropriate investments for pension fund investing. This case could also be used in a strategy class, focussing on the five forces question, and eliminating the valuation question.

There is a great deal of literature about IPOs and their long-term performance. An excellent source is Jay R. Ritter's research, http://bear.warrington.ufl.edu/ritter, which has a longer time period and more data than could be contained in this case. IPO puzzles include persistent undervaluing of IPOs; in other words, the offer price is lower than, and sometimes substantially lower than, the first day close price. A second issue is the generally poorer long-run performance of companies after their IPO when compared to similar firms that did not do an IPO.

The data used to present this case was collected from secondary data sources. These sources included media reports associated with Michael Jordan and his trajectory since entering the sport, as well as specific information published about his time at the Chicago Bulls. Another key source of information is the ESPN documentary conducted specifically on Jordan’s relationship with his National Basketball Association (NBA) team.

The case follows the story of Michael Jordan, who took his team, the Chicago Bulls, to fame in a rather controversial manner. To do so, Michael Jordan had to alter his leadership style over the years to be respected as a leader and motivate his team to win one NBA championship after another. On 20th April 2020, ESPN’s “The Last Dance”, a 10-part documentary about Michael Jordan and his time playing for the Chicago Bulls was released to much acclaim. The documentary became highly noted as Jordan himself, both directed and starred in the documentary. Jordan’s great achievements stood out, but so did the conflicts that the basketball star had with The Bulls’ management team and mainly, his teammates. Relationships between teammates were far from harmonious, which led to questions around whether Michael Jordan was as good a leader, as he was a star player. Cultural change within the organisation was primarily linked to the often-contested leadership of Jordan.

The case can be used at UG, MSc and MBA levels. It works for in-person teaching and for online teaching. It is most suitable in leadership, strategy and strategy in practice courses. However, it is critical to note that the case can shed light on the dynamics that leaders and teammates have within their teams. Therefore, this case may be valuable to students studying courses where they themselves must work in groups and oftentimes encounter challenges in managing their team. These challenges can arise at all levels of experience. As such, the case provides particularly useful reflection for decision makers who may be beginning to develop their leadership skill (UG), those who have already experienced working in teams (MSc) or leading teams themselves (MBA, Executive MBA). The case addresses the challenges associated with achieving high team motivation and performance. It also sheds light on the challenges associated with leading a cultural change within a team and the approaches of different actors involved. It may be best to introduce the case in the context of a (1.5–2 h) workshop once students understand the basic frameworks and tools used to analyse leadership styles and their characteristics.

At the dawn of the twenty-first century, Boeing and Airbus, the leading manufacturers of large aircraft, were locked in a battle for market share that drove down prices for their new planes. At about the same time, the two industry heavyweights began developing new aircraft families to address the future market needs they each projected.

Aircraft take many years to develop, so by the time the new planes made their inaugural flights, significant changes had occurred in the global environment. First, emerging economies in the Asia-Pacific region and elsewhere were growing rapidly, spawning immediate and long-term demand for more aircraft. At the same time, changes to the market for air travel had created opportunities for new products. These opportunities had not gone unnoticed by potential new entrants, which were positioning themselves to compete against the market leaders.

In October 2007, the Airbus superjumbo A380 made its first flight. The A380 carried more passengers than any other plane in history and had been touted as a solution to increased congestion at global mega-hub airports. Four years later the Boeing 787, a smaller long-range aircraft, was launched to service secondary cities in a point-to-point network.

The case provides students with an opportunity to analyze the profit potential of the global aircraft manufacturing industry in 2002 and in 2011. Students can also identify the actions of participants that weakened or intensified the pressure on profits within the industry.

Microsoft Office was facing an uphill task in engaging the undergraduate student community. Attracting this audience—the most tech-savvy generation ever—was critical to the future of the Microsoft Office franchise. Microsoft's past advertising efforts to reach this audience had proven lackluster, while its key competitors were gradually entrenching themselves among this demographic. Microsoft's challenge was to determine the best tactics that could successfully connect with this audience. The (A) case describes Microsoft's dilemma and briefly addresses what college students mostly care about: managing homework, creating great-looking schoolwork, preparing for the workplace, and collaborating with friends and classmates. It also provides competitive information, chiefly Google's increasing presence in universities and its focus on the higher education market and the growing influence of Facebook among students and its evolution into a productivity tool. The (B) case describes the qualitative research tools that Microsoft used to get a better understanding of college students: day diaries using Twitter, technology diaries using the Internet and smartphones, focus groups, and one-on-one interviews with students. The case helps students understand the value of ethnographic and qualitative research techniques, draw inferences from the data, and subsequently make recommendations. It illustrates how ethnographic and observational studies enrich research by generating deeper consumer insight than traditional methods.

Students will learn: - How online tools in ethnographic and observational research offer new insights not revealed by traditional survey research - How different qualitative market tools are used to collect data, as well as the pros and cons of different ethnographic research techniques - To interpret and synthesize data from qualitative and ethnographic research - How research can influence a firm's marketing and advertising tactics
