A senior manager at Ergonomica Consulting was under pressure to demonstrate to her client Solltram Hotels that the hotel's investment in LED lighting would provide a payback. Winning the client's buy-in would lead to an extension of the contract with the client, development of a new specialist practice area within Ergonomica Consulting, improvement of the manager’s chances of promotion, and the cementing of her reputation. However, at a critical moment, the manager discovered that a previously hidden error in her main spreadsheet, which contained over two million data points, had resulted in her overestimating the cost savings for the client. Should she conceal the mistake and win the important contract, improving her chances of promotion? Or should she own up to the mistake and risk losing the account, her promotion, and her reputation?

For the Deutscher Fussball-Bund e.V. (DFB)—the German Football Association—winning the most prestigious football trophy, the 2014 FIFA World Cup, was the culmination of a long period of suffering, reinventing, and rebuilding. Once the dominating force in world football, the German team had been at rock bottom around the beginning of the millennium. To manage its way out of this crisis and leave competitors behind once again, the DFB had to fundamentally reinvent itself. The turnaround required radical changes that would take a long time to pay off and involved substantial risks. How did the DFB reinvent itself to overcome the crisis and regain competitive strength, culminating in triumph at the 2014 FIFA World Cup in Brazil? How could DFB’s managerial options be applied to the corporate world and provide lessons on successfully managing a crisis? What could DFB’s management do to remain at the top of international football?

Hisense Co., Ltd. (Hisense) was the fourth-largest television maker in the world, but its market share and brand recognition remained low in Europe. Therefore, strengthening its branding and improving its sales there were priorities for the Chinese company. In 2013, Hisense was considering whether to establish a strategic alliance with the German high-end television manufacturer Loewe AG (Loewe). Despite having a good reputation, Loewe was suffering severe financial distress and facing possible bankruptcy. If Hisense co-operated with Loewe, it would gain access to Loewe’s distribution network in Europe and utilize co-brand advertising with Loewe. In turn, Loewe would benefit from Hisense’s long-term technical support and gain access to the promising Asian market. Should they proceed?

In 2017, Volkswagen Group was not satisfied with its performance in India. Tata Motors Limited, on the other hand, had been dealing with increased competition from new automobile players. In March 2017, both players made the announcement of a potential strategic alliance with one another. However, the alliance talks soon stalled over the potential use of a platform and the practicality of the business model. The question facing both companies was whether to work out their differences and move the alliance forward, or to terminate the negotiation talks and operate independently.

By 2017, Wal-Mart Stores, Inc. (Wal-Mart) had shaped purchasing power for more than a million U.S. workers. Wal-Mart’s economic muscle was so profound that one could assume that the corporation’s wage policies had had a significant impact on the struggle for a living wage in the United States—but did this assumption have any merit? Wal-Mart had set the benchmark for low-cost retail labour practices. Understanding how Wal-Mart set the agenda with wages invited the investigation of a few pertinent questions: What socio-economic forces were in play and what was the environmental context that shaped Wal-Mart’s approach to managing its labour force? What were Wal-Mart’s wage-related practices, and how did the hourly rate paid to workers by the corporation affect prevailing wage rates? Finally, what were the benefits for Wal-Mart if it pursued a progressive wage rate agenda related to a living wage, and what were the disadvantages if it did not?

In late 2015, the chairman of Sofame Technologies Inc. (Sofame), a Montreal-based manufacturer and marketer of energy-recapture systems, faced a dilemma. The firm, which transformed the waste heat generated by hot water and exhaust gases into usable energy, had struggled for more than a decade as it coped with low gas prices and a failed carbon credits management subsidiary. Sofame had just been delisted from the stock market and was precariously close to bankruptcy. However, the chairman continued to see value in Sofame and was considering a restructuring plan that involved the acquisition of a New York-based boilermaker that could save the firm. In addition to the financial viability of the acquisition and the difficulty of raising funds, he also needed to consider other issues, including the fact that, as the chairman of a Canadian Crown corporation, he could not preside over a firm undergoing the bankruptcy process.

Survival analysis refers to a collection of statistical techniques used to analyze the occurrence and expected timing of events. Survival analysis can provide not only the probability of an event of interest occurring, but also the time at which the event is likely to occur. A particularly useful application of survival analysis is in the area of "customer churn"-the loss of clients or customers-which is a major concern in many industries. This note introduces survival analysis and discusses two approaches to examine customer churn: the Kaplan-Meier estimator and the Cox proportional hazards model. Instructions are provided on how to build these models in Microsoft Excel, without add-ins.

In June 1913, President Woodrow Wilson confronts a legislative deadlock over terms to define a new Federal Reserve Bank for the United States. The recent panic of 1907 triggered a major civic reaction that sought to dispense with a 100-year-old antipathy to central banking. Now, Wilson must decide how best to harness the civic reaction in framing a new central bank. Wilson's dilemma occurs in the midst of a dramatic regime shift in American politics. The rise of Populists and Progressive politicians in reaction to the rapid transformation of America in the Gilded Age marks 1913 as a historic pivot point. It is useful to consider how the panic of 1907 contributed to that pivot and how the public subsequently reacted to the panic. This case and its supplemental B case are a vehicle for illuminating the dynamics of financial crises, comparing systems for financial stability such as clearinghouse associations and central banks, considering the origin of the U.S. Federal Reserve System, and exploring the dynamics of government policy making in the context of a regime shift in political sentiment.

Supplement to case UV7329. This follow-up to "The Panic of 1907 and the High Tide of Progressivism (A)" (UVA-F-1781) explores how well the Federal Reserve Act of 1913 addressed the issues exposed by the panic of 1907, as well as providing further food for thought about financial reform.

This case uses Japan's low-growth episodes since the 1990s to analyze economic policy in an environment featuring excess capacity, low growth, and low inflation. The case discusses the rationale behind "Abenomics"-Prime Minister Shinzō Abe's three-pronged approach to stimulating Japan's economy. In the case, Haruhiko Kuroda, the governor of the Bank of Japan (BOJ), is tasked with making the case to stick with Abenomics after five years under the policy. Were the three prongs of policy changes on course or was one or more of the prongs failing to reenergize growth? The answer would be especially topical during the upcoming general election, which many viewed as a referendum on Abe's economic policies.

In 2017, JetBlue, the airline founded on the mission to "bring humanity back to air travel", was considering becoming one of the first companies to report its sustainability performance according to the Sustainability Accounting Standards Board (SASB) standards. SASB standards identified climate change, labor issues, and corporate governance issues as important considerations for companies in the airline industry. Despite operating as a smaller player in an industry dominated by few legacy competitors, JetBlue leadership saw the company as a driver of industry progress. However, would the adoption of SASB standards help JetBlue achieve the goal of "relevant sustainability leadership?" How developing metrics and improved performance on material sustainability issues could be used as an instrument for change management? Should Sophia Mendehlson, the Chief Sustainability Officer, integrated Environmental, Social and Governance (ESG) metrics in the regulated fillings as in the 10-K, in separate sustainability reporting mediums, or as a separate report? JetBlue believed sustainability was more than simply a risk mitigation tool. Was it?

Founded in 2012, Jumia Nigeria, a startup effort by Germany-based Rocket Internet, aimed to become an African Amazon. The company entered the nascent market and immediately enjoyed an uptick in consumer spending fueled by the strength of Nigeria's oil-based economy. By 2016, however, Jumia's growth had begun to taper, hindered by plummeting oil prices, the subsequent economic downturn, and the pressure of Nigeria's limited retail ecosystem. In addition, Jumia's inventory-intensive retail model required significant infusions of capital that, in the face of a deteriorating economy and the company's inability to show a profit, was becoming increasingly difficult to obtain. Considering all this and looking to the success of the Amazon and Alibaba marketplace models where third-party sellers largely carried inventory costs, the Board had made a drastic decision: Jumia would shift from an online retail model to a marketplace model. They also made it very clear that a failure to properly implement this transition could mean the end of investor support for Jumia. Senior management wondered how they would meet the challenges ahead. While Amazon in the US and Alibaba in China had found success with the marketplace model, they wondered if Jumia would be able to do the same. Was this the right model for the very different Nigerian environment? Would vendors, many of whom already had retail operations in the country, choose to sell through Jumia? How could Jumia continue to provide the same high quality customer service on which the company's success had been built while switching to a marketplace model in which parts of this critical aspect would now be in the hands of third parties?

This follow up case study explores the ramifications of Jumia's decision to move from a retail led to a markplace business model for its e-commerce platform. The case visits the company's successes as well as its many failures when adopting this vendor-led strategy. It also considers Jumia's options going forward- should it return to the retail-led model or develop a hybrid alternative?

In the Republic of Georgia, legend had it their land was a precious gift from God he had intended to keep for his mother. But over time, the land had been under intermittent threat from without and within. In 2017, the Bitfury Group, which Valery Vavilov had co-founded, had helped publish 300,000 Georgian land titles onto the blockchain, making them immutable and, many believed, unhackable. What came next, Vavilov's team envisioned, were smart purchase and sale contracts via the blockchain; and from there, a full suite of property-related services and, eventually, blockchain as the foundation for a transformation in government services. Vavilov, who had co-founded Bitfury and expanded it substantially from its bitcoin mining roots, felt a blockchain-driven makeover of this sort would take place not just in Georgia's government, but around the world. It was not a matter of "if?" anymore; although that still left the question of "when?"
