The case illustrates how Microensure deploys strategies for the bottom-of-the-pyramid (BoP) as the cornerstone of a successful, cost-efficient scale-up that aims to democratize insurance in countries where consumers have very low incomes.

Agility is often mentioned but seldom defined or clearly illustrated. This case discusses UNICEF's response to the sudden disruption of its aid supply chain to Yemen after the bombing started in 2015. It illustrates how a forwarding hub was quickly established in Djibouti and dhow vessels were used to reach small Yemeni ports from there. The case analyzes the supply chain, the organizational and strategic aspects of agility and discusses how UNICEF can further develop its strategic agility as an organizational capability. It can be used in supply chain and strategy classes, as well as classes on change management and fast decision making processes in organizations. If you buy the case you will get access to all three parts, A, B, and C. Part A outlines the events leading up to the Yemen Crisis and presents the challenges faced by UNICEF. Part B then describes UNICEF's response to the crisis, and part C gives an analysis of this response. Parts B and C are restricted to instructors and only available on the dedicated case website https://cases.insead.edu/humanitarian-agility, but can be distributed to students as well.

Supplement to case UV7401. The president of the Belgian consumer goods subsidiary had made a conscious effort to engage his direct reports in ways that he felt aligned with their personalities. He had noticed some modest changes in the weekly management team meetings-all team members had begun taking advantage of opportunities to contribute to the deliberations, posing questions, and raising some minor concerns. Now a replacement must be picked to replace the senior marketing executive who had retired.

In 2016, electric car manufacturer Tesla announced that it was making an offer to acquire solar panel manufacturer SolarCity in an all-stock offer worth $2.6 billion in Tesla stock. Tesla's co-founder and CEO, Elon Musk, believed that the merger would generate significant cost and revenue synergies, based on his vision of the future of transportation, energy storage, and a "green" economy. However, most Wall Street analysts were highly skeptical of the deal, voicing concerns that the merger would burden Tesla with excessive debt, and that Musk was using the deal to advance his personal interests (at the expense of public shareholders) and bail out Tesla. Concerns were raised over possible conflicts of interest, given that Musk owned over 20% of the stock, and sat on the board of directors, of both companies. The viability of the merger was also questioned given that neither Tesla nor SolarCity had ever been profitable.

A Somali fisherman stands on a beach in early 2011, considering his options: should he embark in his tiny fishing vessel, or join a nearby pirate crew? His war-ravaged country, entering its twentieth year of civil war, was in the midst of a famine that had claimed hundreds of thousands of lives, and piracy had recently become the country's greatest claim to fame, securing ransoms to the tune of millions of US dollars in one of the poorest corners of the global economy. Why had piracy become such an attractive option for Somalis? Why did some even consider it "just," and how could maritime trade be made safer again?

On the evening of 3 August 1914, British Foreign Secretary Lord Edward Grey contemplated whether to advice King and Parliament to declare war on Germany in the wake of the country's invasion of Belgium, or to stay out of what quickly was becoming a world war triggered by a royal assassination in Sarajevo. Over the past century, the said world had become woven together in ways never before seen, and a truly global economy had emerged that many believed forever would banished the possibility of war altogether. But could trade really assure perpetual peace, and what ultimately mattered most; interest, or principles? The case considers the lessons to be had from the rise and fall of the last great period of globalization.

Horizontal and vertical analysis assignment hints for case BAB372.

Clover Network's founders didn't see the curveball coming at the end of 2012. The two-year-old start-up had just nine employees. It had dumped its first business idea, pivoted from its second, and was working hard on a new product: a tablet-based cash register with built-in credit card processing. Large credit card payment processing companies had started noticing Clover and one had just agreed to pre-order $2 million of Clover hardware. It was Clover's first such deal. But around Thanksgiving, Clover learned that First Data-the card processing industry's 800-pound gorilla-also was interested in Clover's technology. If it could bring First Data on as a customer, Clover would have a pipeline to a huge number of retailers. In early December, one of Clover's founders received a 2½-page letter from First Data. He had expected a proposal to buy and distribute Clover equipment, maybe with a small equity investment. Instead, First Data said it wanted to acquire "no less than 75 percent" of Clover, and close the deal by December 31. Was it time to sell Clover? The case highlights how a start-up decides to respond to an unexpected buyout offer and how it proposes to structure the deal.

Supplement to case HEC199. From 2008 to 2015, Valeant Pharmaceuticals International Inc. (Valeant) was a Wall Street darling under the leadership of CEO Michael Pearson. The company's stock price soared as Pearson went on an acquisition spree. Critics questioned Valeant's capacity for organic growth and its lack of commitment to research and development (R&D). In October 2015, investors began losing confidence when Valeant was subpoenaed to testify before the U.S. Senate Committee about its price-gouging practice. On-going investigations by the U.S. House Committee and Attorney's Offices regarding Valeant's patient assistance program and business relationships with Philidor Rx Services also contributed to the company's downfall. In May 2016, Valeant hired Joseph Papa to replace Pearson as CEO. One of Papa's top priorities was to pay down the $30 billion debt amassed to finance the company's acquisitions. In Case (A), students learn about the company's executive incentive compensation philosophy, acquisitions, and governance practices and are asked to assess the financial impact of Valeant's acquisitions. In Case (B), students are asked to identify the factors driving Valeant's stock price down and to assess the company's ability to pay down its $30 billion debt.

Supplement to case UV7380. In this case, James Jones and William West's company, JW Sports Supplies, has begun to offer a second product line-a customized gym bag. The owners consider the topic of overhead allocation in determining the cost of its basic gym bag and the new customized gym bag. The company currently uses a traditional overhead allocation system, with one cost pool being allocated based on units. Noticing that the custom gym bags tend to be ordered in small batch sizes and require more time from the sales staff to sell, the owners consider the implications of an activity-based cost system. After allocating overhead costs based on an activity-based cost system, students must consider potential alternative courses of action that they could explore.

This three-part case covers the history of Samsung from its origins as a small trucking company to one of Korea's largest conglomerates. Part A, "Drivers of Success, Family Assets and Business Strategy", charts the growth of Korea's the export-led economy after the end of Japanese occupation in 1945, driven by a handful of family-owned 'chaebols'. Founder Lee Byung-chull's trucking business, set up in 1938, diversified in the aftermath of the Korean War, as he forged a strong political network that enabled him to embed his family's influence and assets in the business strategy. Part B, "Heart Attack Puts Succession Planning at Risk", describes how the ill health of the second-generation leader Lee Kun-hee deprived the firm of a clear succession plan. As the de facto leader of Samsung, his son had to build up his power base to assume the role in the context of a complex ownership structure. Part C, "Court calls time out on Lee Jae-yong", examines how the de facto heir was convicted of bribery and given a five-year prison sentence, prompting speculation that he would run the Samsung empire from his cell.

In 2017, Miami was rated #1 among U.S. cities for startups, but about 40th for "scale-ups" - growth companies. This case shows how leaders of incubators and accelerators supported startups and a culture of entrepreneurship, but also describes some factors limiting growth, including a lack of local venture capital, big companies to serve as local customers or partners, and biases on the part of investors. The question is whether co-working spaces, training programs, and networks go far enough to build a new tech center for the future economy.

The effects of Miami's startup scene have not reached many "left-behind" lower-income Black communities, which are disproportionately affected by problems such as segregation and racial discrimination, lack of transportation access, crime, education quality, government incompetence, and climate change. Leaders such as mayors, real estate developers, civic entrepreneurs, and community activists are offering solutions to the systemic problems faced by Miami's lower-income Black communities. Can more innovative thinking and the entrepreneurial spirit help move such areas into the tech economy/green jobs future?

Supplement to case 717004.

This case, along with its A case (UVA-QA-0864), is an effective vehicle for introducing students to the use of machine learning techniques for classification. The specific context is predicting customer retention based on a wide range of customer attributes/features. The specific techniques could include (but are not limited to): regressions (linear and logistic), variable selection (forward/backward and stepwise), regularizations (e.g., LASSO), classification and regression trees (CART), random forests, graduate boosted trees (xgboost), neural networks, and support vector machines (SVM). The case is suitable for an advanced data analysis (data science, machine learning, and artificial intelligence) class at all levels: upper-level business undergraduate, MBA, EMBA, as well as specialized graduate or undergraduate programs in analytics (e.g., masters of science in business analytics [MSBA] and masters of management analytics [MMA]) and/or in management (e.g., masters of science in management [MScM] and masters in management [MiM, MM]). The teaching note for the case contains the pedagogy and the analyses, alongside the detailed explanations of the various techniques and their implementations in R (code provided in Exhibits and supplementary files). Python code, as well as the spreadsheet implementation in XLMiner, are available upon request.
