Case studies

Tiffany & Company was the leading U.S. luxury jewelry brand, generating more than $2.6 billion in revenue through 167 retail outlets globally and from catalogue and Internet sales. For nearly 170 years, Tiffany had managed its brand. In February 2007, a hedge fund, Trian Fund Management LP, announced that it had bought a 5.5% stake in Tiffany, and became its largest shareholder. Trian believed that Tiffany was undervalued and stated that it wanted to help the company “improve its earnings per share by addressing various operational and strategic issues.” In response, Tiffany began to consider different actions to increase shareholder value.

The case revolves around a marketing/sales executive who works in the Ad Sales wing of a popular search engine. Over the course of the case, the protagonist realizes that their marketing strategy needs to refocus on a different vertical than the one they have been paying the most attention to. He had done the required data analysis and feels the data strongly points to a need for change in their strategy. However, he needs to convincing the higher management by put together a compelling pitch using storytelling elements, so that the message in his data gets across clearly, compelling them to act.

After a tumultuous five months, Nestle India was exonerated in the Maggi crisis just in time for Diwali. Although the mood was one of vindication, the leadership team with Suresh Narayanan at the helm, knew they faced a major challenge to regain lost glory. Stock price had plummeted along with consumer confidence which went down from over 90 to less than 5 per cent. Part B traces the efforts of Nestle India to not only reinforce the message of product quality but also to engage consumer trust. Through changes in product strategy, organizational structure, and multi-pronged communication, Maggi was able to rekindle the emotional connect with the consumer and surge back. On 30 November 2019 despite loss of market share, consumer faith and trust in 2015, Nestlé India was trading at INR 14,453/55 (NSE/BSE;~US$225) per share after hitting a record low of INR 4981 (~US$76) on 29 February 2016. Part B of the case outlines the measures Nestle India took to bounce back and asks if Nestle India's reputation out of the woods. Could the past come back to haunt Maggi or was the worst behind them? 1. Evaluate communication strategies available to organizations in a crisis situation. 2. Analyse the power and influence of consumer sentiment in reputation management.

The case has the following learning objectives:

1. understand the various types of comparisons that are possible between groups over time and across space;

2. evaluate a policy intervention using relevant data and different methods; and

3. understand the meaning of the phrase “controlling for other relevant factors” in regression and non-regression contexts.

The difference-in-differences (DID) approach is a useful tool for making meaningful comparisons. This case tries to provide a non-technical introduction to the approach using a basic comparison of crime rates among districts in Punjab (Pakistan's largest province). Being the most populous region of the country, Punjab faces many governance challenges, and street crime is one of them. (Exhibit 5 provides additional information about the geographical and administrative setting used in this case study.) In 2016, Chief Minister Shahbaz Sharif established the Dolphin (police) Force in different locations to improve urban patrolling and reduce street crime. There were debates about the effectiveness of the Dolphin Force (DF).

Those who are skeptical of DF point to various situations that were handled incorrectly by DF personnel, as well as other administrative and operational problems in the initiative. Optimists believe it is beneficial and want it to be expanded to other districts and regions. The threat of street crime claims many lives and, according to optimists, necessitates the formation of a special force. Whether the huge resources invested in the DF worth their lot or not can be known through sound statistical analysis that can identify the difference in the rate of crime because of the DF. In this instance, the case provides information to answer the following question:

Is there a significant difference in crime rates between areas where the DF is operating and districts where it has not yet been installed?

In quantitative/statistical analysis classes, the case can be used to teach the DID technique to MBA/MS Applied Statistics/Applied Data Analysis students. It can also be used in undergraduate Econometrics classes.

The COVID 19 pandemic-related restrictions devastated South Africa’s economy in 2020 and although the restrictions were generally less damaging than in 2020, the government had to budget for vaccinations and rebuild the economy. Public service unions had just announced that they were demanding an increase of 4% above inflation for their members and that they were preparing for a strike. They were bitter about the fact that the South African Government had withdrawn from the last year of a three-year wage agreement in February 2020 and their members had not received an increase for the two years. These demands and Finance Minister Mboweni’s response to them had to consider the structural and cyclical impact on the fiscus and economy.

The learning outcomes are as follows: understand the general objectives of fiscal policy and stakeholders’ interests; understand the tradeoffs in fiscal policy and the implications of taking a position; and make recommendations based on reasoned judgements about those recommendations.

The learning outcomes are as follows: How to establish credibility of data sources; measurement scales of data; the importance of descriptive statistics and generating the following based on the type of data: mean, median and standard deviation; graphical methods; and test for differences: t-test and analysis of variance.

The case is set during the COVID-19 pandemic and the South African Government’s response to the pandemic. A brief timeline is provided as part of the introduction to the case study, with the following being a timeline of the events: 14 March 2020, 114 South African citizens were repatriated from Wuhan the epicentre of the COVID-19 outbreak; 15 March 2020, South Africa’s President, Cyril Ramaphosa declares a National State of Disaster, and this includes various measures to protect against the spread of COVID-19, while the health-care system is geared up to deal with the pandemic. Among the measures implemented, travel bans from high-risk countries and closing of air-traffic, closing of land ports and banning of gatherings of more than 100 people; 23 March 2020, President Cyril Ramaphosa announced a national lockdown beginning on 27 March 2020 for three weeks; 9 April 2020, President Ramaphosa extends the national lockdown by a further two weeks. The World Health Organisation (WHO) had commended South Africa on the swift action taken to curb the spread of the virus. Individuals and organisational leaders are grappling to make sense of the spread of the virus, and the barrage of the information that is being communicated through multiple channels, formal and informal. To make sense of the information, the case is premised on getting access to the raw data and conducting the analysis based on the publicly available data. The central requirement of the case is to compare the number of positive cases per million, based on the population data contained in the data set, of South Africa to a comparable country.

The learning outcome is to understand the difference between correlation and causation.

The case is set during the period of the COVID-19 pandemic, globally a search for effective treatments were underway. An initial forerunner that was being considered was Bacille Calmette-Guerin (BCG), given its effectiveness in the treatment of tuberculosis and other pulmonary-related infections. While there were a lack of randomised controlled trials, initial data from publicly related secondary data sources indicated that, in countries with BCG inoculation policies, the severity of the spread and mortality of COVID-19 was muted. The case is centered around the available information on BCG and COVID-19.

After the successful release of the first Hunger Games film in 2012, the film's distributor, Lionsgate, was preparing to release the next movie in the series, Hunger Games: Catching Fire. Fan expectations had grown after the success of the first film, and Lionsgate faced the challenge of keeping moviegoers interested and engaged in another Hunger Games movie. In an era marked by the rising popularity of digital and social media, Lionsgate knew that attracting fans to a sequel meant pushing the boundaries of traditional marketing tactics.

Digital brand storytelling is about using digital media in a holistic way to tell a brand story and build excitement for an audience. Brand storytelling seeks to make a connection with the audience by giving them an emotional experience that resonates with them. While Lionsgate was aware that traditional marketing would need to be blended with a digital campaign to bring in moviegoers, it also needed to strike a careful balance between the two and choose the appropriate platforms to tell a cohesive story. Should Lionsgate launch a brand storytelling campaign to appeal to fans? Lionsgate's comparatively small marketing team gathered to brainstorm about how to execute such a campaign and position the film for another big success.

The case can be used in the subject areas of finance and in particular investments, corporate governance, ESG, or responsible investments. It is suitable for students from all financial backgrounds, from a novice in the financial markets to an expert in finance. It is, however, expected that the class should have a sound fundamental grounding in financial analysis and valuations. The purpose of this case is to prepare students for future investments they would make in whatever capacity – whether in private or listed companies – and to prepare them for future roles on boards of directors. The examples of real-life events in this case study are used to prepare students for future similar situations in which they might find themselves.

This teaching case is aimed at postgraduate students pursuing an MBA or a specialist Masters in a finance programme. This case can be used as a master class in corporate governance, investments, or responsible investments. This case is also suited for an executive education class in management. It is particularly relevant to a module that focusses on investments, corporate governance, ESG, or responsible investments.

The case study chronicles meetings held on 8 November 2017 at a fictional South African asset manager, Active Investment Management (AIM). These meetings discuss the firm's investment in JSE-listed Steinhoff International Holdings. The case deals with the questions that active fund managers need to address when balancing financial analysis; environmental, social, and governance (ESG) analysis; portfolio management; and the need to comply with their fiduciary duty to clients. It also looks at the need for responsible investing in decision-making.

The understanding of the assessment around the complexities of asset management when it comes to responsible investment.

To determine why institutional investors should apply responsible investment principles when making investment decisions.

An understanding of the evaluation of the unique roles of the three pillars of corporate governance, namely asset managers, auditors, and the board of directors.

The ability to assess how to integrate financial analysis and ESG principles in making investment recommendations.

The case describes the fall of Eskom, which in 2001 was named the Financial Times’ Power Company of the Year, but by 2019 was suffering from “systemic corruption, malfeasance, fraud and state capture” that had “compromised the credibility of the organisation and eroded investor confidence”. Eskom’s incompetent management lays the ground for reasonable doubt as to whether the force majeure notice was indeed irresistible. The case suggests several methods available in financial markets to hedge risk – but to what extent are these relevant and appropriate? The main objective of the case, however, is to examine and assess the criteria required to claim force majeure. Two aspects are questionable: Was the virus unforeseeable and was it irresistible? Eskom is “bleeding” R².5m per month because of significantly reduced electricity demand, and while it clearly benefits Eskom to break their supply contract, the consequences for Exxaro are far more dire. And, if carried to conclusion, how would such actions impact the entire economy?

In April 2020 South Africa’s stated-owned electricity utility Eskom sent a pre-cautionary force-majeure notification to Exxaro Limited’s Grootegeluk Coal Mine. The notification, citing COVID-19 as an unforeseeable, external and irresistible event, would have disastrous consequences for the mine’s 25 m tonnes pa coal contract to supply Eskom’s Medupi power station. Not only was the legality of the force-majeure questionable, it was unethical, and not in the spirit of President Ramaposa’s call to businesses to continue paying contractors. The case briefly describes Eskom’s troubled history following South Africa’s 1994 democratic election. It examines the force majeure clause common in contracts, and questions whether COVID-19 meets the criteria of an “unforeseeable, external and irresistible” event.
