In 2010, 97% of the world's supply of rare earth elements (REE) came from mines in China. Global demand tripled from 40,000 tonnes to 120,000 tonnes between 2000 and 2010 while China steadily cut its annual exports. Fears of a crisis in Western countries increased as alternative supplies of these materials were sought. REE were used in a number of products, including in the military industry. Reports indicated that the US defence industry was "totally dependent" on imports of REE and advised defence contractors to try to limit their dependence on these materials as well as to actively seek substitutes. The United States faced the challenge of rebuilding domestic REE supplies to achieve self-sufficiency and protect the environment.

Prayas is a unique healthcare initiative, launched in India by Sanofi-Aventis, a French multinational pharmaceutical company, with the objectives of updating the medical knowledge of doctors in semi-urban and rural areas, bridging the gap between diagnosis and treatment, and making available quality medicines at affordable prices. This case discusses the evolution of the Prayas model from its inception to its current state, and the company's business strategies around it. Cognizant of the success of Prayas, many competitors of Sanofi-Aventis are actively developing and implementing similar models. The company's top management team has to respond to the competitive threat.

Regulatory uncertainty has been inherent in climate change policy due to the absence of a successor to the Kyoto Protocol. Many companies have called for more certainty and a stable policy framework. However, besides having clear disadvantages, regulatory uncertainty may also benefit some companies if they recognize the opportunities of flux and move early. This article explores business opportunities that have emerged for different types of companies, including utilities, banks, project development & carbon offset companies, brokers, exchanges, consultants, auditors, and legal services providers with respect to clean development projects and the related carbon market.

Coping with uncertainty is a fundamental challenge for firms. One way they can respond is by building up strategic flexibility. By looking at airlines' flexibility responses to regulatory uncertainty associated with their inclusion in the European Union Emission Trading Scheme, this article shows that firms can respond to regulatory uncertainty by developing such flexibility in two ways: they can either anticipate the potential consequences of changing regulatory conditions and try to prepare for them; or they can adapt quickly and efficiently to them once the regulatory situation has become clear. By examining evidence from nine case studies, the article identifies the organizational capabilities required to pursue an anticipatory or adaptive strategy and demonstrates that each type of response requires a specific bundle of capabilities.

Automotive assemblers and suppliers have employed a number of different strategies to deal with external uncertainty. These strategies have evolved relatively rapidly of late in part because of changes in the locus of innovation from OEMs to suppliers, changing market conditions, and the future regulations of greenhouse gases. This presents a unique challenge for the industry. Some auto firms have been more effective in dealing with market and regulatory uncertainty due to technology resource integration across platforms and integration between functions on the value added chain from suppliers to retailers.

This article offers two integrated strategies managers can use in the face of environmental regulatory uncertainty. As integrated strategies, they both recognize non-market forces while taking into account market realities. Advocating for pragmatic, progressive policies enables firms to shape future policy around existing environmental strengths; this strategy raises competitors' costs when competitors have yet to develop identical competencies. Systematically embracing advancing regulation enables firms to satisfy activists who are pressuring policymakers to force firms to conform to higher environmental standards in other jurisdictions; this strategy allows managers to adapt to coming regulation at their own pace while leveraging market competencies. This article presents four case studies that highlight how some firms have implemented these strategies, and why some have been successful at mitigating regulatory uncertainty and some have not.

With the world's population estimated to grow by 40% by 2050, an additional supply of grains, meat and dairy products would be required. Concerns over the global food supply have increased. Also, with China's growing urbanisation and increase in per capita incomes, there was additional pressure on the demand for food products. However, with arable land being fixed and in short supply the constraint on the supply side was more acute. The issue of food shortages was taken a lot more seriously in China than it was in other countries around the world, because the Chinese government's memories of the Great Famine in China between 1958 and 1961 were still too recent to take the matter lightly.

This exercise assesses one's exposure to the rest of the world's peoples. A series of worksheets require the respondents to check off the number and names of countries they have visited and the corresponding percentage of world population which each country represents. By summing a group's collective exposure to the world's people, the result will inevitably be the recognition that together they have seen much, even if individually some have seen little. The teaching note provides assignments and discussion questions which look at: why there is such a high variability in individual profiles; the implications of each profile for one's business career; and, what it would take for the respondent to change his/her profile. For marketers, it underscores the need to gather greater base knowledge about opportunities abroad.

The cases describe the demise of Arthur Andersen, a firm that had long set the industry standard for professionalism in accounting and auditing. Once an example of strong corporate culture with a commitment to public service and independent integrity, Andersen saw its culture and standards weaken as it grew explosively and changed its mode of governance. The (A) case describes a crisis precipitated by the admission of Waste Management, a major Andersen client, that it overstated its pretax earnings by $1.43 billion from 1992 to 1996. The resulting Securities and Exchange Commission (SEC) investigation ended with Andersen paying a $7 million fine, the largest ever levied against an accounting firm, and agreeing to an injunction that effectively placed the accounting giant on probation. Students analyze the causes of Andersen's problems and advise Andersen leadership. The (B) case covers Arthur Andersen's relationship with Enron, one of the great success stories of the "new economy" boom. When Enron's aggressive use of off-balance sheet partnerships became impossible to hide in autumn 2001, news reports stated that Andersen auditors had engaged in extensive shredding of draft documents and associated communications with Enron. Students are asked to act as crisis management consultants to Andersen CEO Joe Berardino. The (C) case details Andersen's collapse following its indictment and conviction on criminal charges of obstructing justice in the Enron case. Its conviction was later overturned by the U.S. Supreme Court on narrow technical grounds, but by then Andersen had ceased to exist, eighty-nine years after Arthur E. Andersen had taken over a small accounting firm in Chicago. Students can focus on the impact of media on a reputational crisis.

MentorMob had sprung from the passions-for web development and for online communities-of the company's co-founders, Kris Chinosorn (CEO) and Vince Leung (COO). The company pursued the ambitious goals of reinventing the way people learn and becoming the world's utility for learning about anything. The website leveraged a crowdsourcing model for information sharing, teaching, and learning. By enabling participants to learn-and to crowdsource from each other while learning-the site sought to both engage users at different stages of learning and to develop a compelling experience unobtainable without a crowd. Chinosorn and Leung needed to prioritize in order to achieve the growth and scale needed to become world's utility for learning. What should they do next to keep MentorMob's growth on track? What issues should get their greatest attention?

Corporate leaders have long subscribed to the belief that the sole purpose of business is to make money. That narrow view, deeply embedded in the American capitalist system, molds the actions of most corporations, constraining them to focus on maximizing short-term profits and returns to shareholders at the expense of worker safety and health, the environment, and society in general. In this article, HBS professor Kanter argues that a very different logic informs the practices of most high-performing and sustainable companies: an institutional logic. These companies believe that they are more than money making machines; they are also a vehicle for advancing societal goals. They deliver more than just financial returns; they also build enduring institutions. At great companies, institutional logic takes its place alongside economic logic in research, analysis, and managerial decision making. Six facets of institutional logic-a common purpose, a long-term focus, emotional engagement, partnering with the public, innovation, and self-organization-radically alter leadership and corporate behavior and form the building blocks of a more sustainable competitive advantage.

The sharper a company's differentiation, the greater its competitive advantage. In studying companies that sustained a high level of performance over many years, the authors, both partners at Bain, have found that more than 80% of them had a well-defined and easily understood differentiation at the center of strategy. But differentiation can wear with age: The growth it generates creates complexity, and complex companies tend to forget what they're good at. Often they respond by trying to reimagine their entire business models quickly and dramatically. That's rarely the answer, the authors write. Really successful companies relentlessly build on their fundamental differentiation, going from strength to strength. They learn to deliver it to the front line, creating an organization that lives and breathes its strategic advantages day in and day out. They learn to sustain it through constant adaptation to changes in the market. And they learn to resist the siren song of today's hot market better than their less-focused competitors do. The result is a simple, repeatable business model that a company can apply to new products and markets over and over again to generate sustained growth.

Although most companies have collected lots of friends and followers on social platforms such as Facebook, few have succeeded in generating profits there. That's because they merely port their digital strategies into social environments by broadcasting their commercial messages or seeking customer feedback. To succeed on social platforms, says Harvard Business School's Piskorski, businesses need to devise social strategies that are consistent with users' expectations and behavior in these venues-namely, people want to connect with other people, not with companies. The author defines successful social strategies as those that reduce costs or increase customers' willingness to pay by helping people establish or strengthen relationships through doing free work on a company's behalf. Citing successes at Zynga, eBay, American Express, and Yelp, Piskorski shows that social strategies can generate profits by helping people connect in exchange for tasks that benefit the company such as customer acquisition, marketing, and content creation. He lays out a systematic way to build a social strategy and shows how a major credit card company he advised used the method to roll out its own strategy.

In recent years criminal organizations have begun to mimic the tactics of legitimate businesses-becoming so sophisticated that they are now creating new best practices in adaptive strategy, supply chain management, the use of incentives, and other disciplines. Companies should study their techniques as a defensive measure, and also because they might well profit from some of the global gangsters' insights.

The majority owner and general manager of City Furniture and Mattress (CFM), needed to make several decisions that would determine the company's strategy. CFM had continued to grow in terms of sales, but the general manager and his father, also an owner and manager at CFM, were concerned with profitability and the increasing competition from local and big-box stores. The general manager looked at several options including capital investment, expanding global outsourcing, and store network expansion and vertical integration.

In 2011, HUGE, Inc. is the fastest growing digital agency in the U.S. Its CEO, Aaron Shapiro, is considering a set of novel growth strategies to take his firm to the next level. However, the digital strategy industry in which HUGE has made a name for itself is highly fluid and constantly evolving-the options facing Shapiro and HUGE must be considered in light of an industry structure that blurs the lines across competitors, complements, and clients and could easily shift for or against digital agencies such as HUGE in the near future. Using HUGE as a focal point, students are asked to evaluate competitive dynamics in the digital strategy industry and predict the evolution of the market. They are also asked to use the unique dynamics of the digital strategy industry as a backdrop for assessing HUGE's best growth option going forward.

Turbine, Inc., is releasing a massively multiplayer online (MMO) game, The Lord of the Rings Online, based on the popular film trilogy.
