In October 2005, Yahoo! Inc. ("Yahoo") formed a partnership with Alibaba Group Holding Limited ("Alibaba"), the country's biggest e-commerce firm. The company invested US$1 billion in Alibaba for a 40% stake and transferred the ownership of Yahoo! China ("Yahoo China") to Alibaba. However, some media outlets have described the two companies' relationship since 2005 as being anywhere from rocky to downright ugly. Yahoo's decision in mid-2009 to switch to Microsoft's Bing search technology has prompted Alibaba to adopt a search engine from Yahoo's local competitor Sohu.com. Then Alibaba collaborates with eBay Inc. instead of Yahoo in entering the US business-to-business market. Meanwhile, Yahoo directly competes with Yahoo! China for advertisers by soliciting companies in southern China to advertise on Yahoo's Hong Kong website. Alibaba has been taking a loss in its operations since 2006, and the search revenue share of Yahoo! China has dropped from 27% in 2005 to an insignificant level in 2010. But Yahoo! has turned down Alibaba's offer to buy back its stake because it would like to wait for the IPOs of Alibaba's two major subsidiaries before any exit. In light of growing tension with Alibaba, Yahoo's board would like to review its approach to managing this partnership and figure out what should be done to mend the ties.

In early 2003, an outbreak of SARS in Hong Kong led to a plunge in inbound travel to the city. Many local travel agencies started hosting below-cost inbound tours, dubbed "zero-fee tours", for mainland Chinese tourists. They make a profit by bringing these tourists to shop in designated retail outlets that charge them inflated prices but offer lucrative commissions to tour operators. Zero-fee tours first caught the public's attention in October 2006 when a group of tourists were abandoned at a pier because they spent too little while shopping. Then in June 2010, a tourist died of a heart attack after a heated argument with a tour guide over a shopping arrangement. Despite preventive measures implemented by the industry association, tourist complaints keep increasing and high-profile cases in which tour guides insult or even fight with tourists continue to happen. Trendy Travel Limited is a local travel agency that hosts regularly priced inbound tours. Facing strong market demand for zero-fee tours, it would like to understand the business model of zero-fee tours: what is the driving force, is it sustainable, and what are the impacts to the company and the entire industry? It also wants to determine how to position its inbound tour business in the short and long term.

Hong Kong Business Intermediary ("HKBI") was Hong Kong's first business brokerage company that specialised in small business sales. Leading the company was Edwin Lee, a young entrepreneur who took his every chance to drive the company to new levels of success. In November 2001, after realising that there were no business brokerage firms in Hong Kong, Lee set up HKBI and started to offer "matchmaking" services for prospective business sellers and buyers. As the company diversified into too many additional services without proper planning, the rising operation cost turned into a cash flow disaster for HKBI in 2005. Lee then restructured his business model into a more systematic and integrated way and successfully turned his company around, earning himself the award of Hong Kong's Innovative Entrepreneur of the Year 2007. HKBI's business model and efforts in promoting entrepreneurship had also received recognition worldwide. Meanwhile, local rivals began to tap into the under-developed sector in Hong Kong, and many of them were former HKBI employees. Lee knew when a blue ocean began to turn red, he needed to continue to reinvent his business to safeguard HKBI's market leader position. He envisioned HKBI to become a small business property developer in the future. How did Lee distinguish HKBI from others by associating the business brokerage operation with the finance, private equity and property markets in an innovative way? How did take it as his employees striking out on their own and becoming his competitors while one the objectives of HKBI was to promote entrepreneurship?

For Chinese corporation Haier Inc, the biggest seller of major appliances in the world, entering India as an emerging market multinational is like having a double-edged sword. Its global presence gives it credibility to offer more sophisticated products that warrant a premium price, but Indian consumers have yet to develop the willingness to embrace its China-made, high-priced products. Seven years into its India business endeavours, sales remained sluggish and market share minimal. The company then undertook a swift change in pricing strategies and overhauled its marketing infrastructure to save its market. The case provides an overview of the situation and lends a discussion of marketing and localisation strategies of emerging market multinationals in India. It also gives insights into the challenges these multinational corporations face. The case also explores issues of product offerings, brand communication, pricing strategies, market capture and late-comer disadvantages. The comparison between Haier's behaviours in India and other markets also points to the level of localisation/globalisation the company adopts across markets.

This note introduces a framework for formulating strategy that helps a manager identify which decisions are strategic-and thus which decisions to focus on (both when developing strategy and when executing it)-and that provides a practical test for whether a particular set of choices is a strategy. The framework is based on the definition of strategy as "the smallest set of choices to optimally guide the other choices."

Three years into a major public-private partnership between GlaxoSmithKline and Fiocuz, Brazil's principal health institute, the company assesses technology transfer and joint research under the agreement. GSK was selling its Synflorix vaccine (against pediatric pneumonia) at fixed prices even as it transferred technology and know-how to Brazil for eventual domestic production. At the same time, GSK was co-sponsoring research into a new vaccine for Dengue fever with the Brazilian government. GSK's management must consider whether the PPP provides strategic advantage to its consumer healthcare businesses in Brazil and to access other emerging markets as well as the risks posed by the aggressive product obsolescence built into the technology transfer agreement.

In the Competition Simulator Exercise, students explore through trial and error some important economic foundations of competitive strategy and managerial economics. In particular, the nine simulator exercises let students explore horizontal differentiation with and without price setting, strategic complements and substitutes and their implications for commitment and for first-mover advantage, the effect of the number of competitors on the competitiveness of a market, capacity limitations and judo economics, natural monopoly and the effect of market size, technology choice as entry deterrence, endogenous economies of scale, and capacity limitation in commodity markets. It can be used to introduce these concepts without necessarily relying on a lot of math or as an intuitive complement to a more mathematical exposition.

The chief executive officer of Mission Hills, a Chinese golf course operator, is thinking about how to expand his resort operations into Hainan Island, a few hundred kilometres away. He is wondering what his organization needs, from a human resources standpoint, to be able to develop another five-star resort. Mission Hills is a top golf course brand in China employing 7,000 people in its Shenzhen and Dongguan facilities. The expansion to Hainan Island is part of a larger plan to establish Mission Hills resorts around China.

Rick Anderson, senior director of NextEra's Green Marketing Group, is crafting a marketing strategy to move Renewable Energy Certificates (REC) on the voluntary market by demonstrating the added value of the company's EarthEra RECs. NextEra not only markets RECs, but also funds the construction of renewable energy projects. Anderson is seeking to expand the EarthEra program and brand. While there has been some good responses to EarthEra RECs, there have also been setbacks. Demand for RECs is decreasing. The end of federal incentives for renewable energy projects, the 2008 financial crisis, and a rejection of federal RPS legislation have depressed the market for voluntary RECs. Anderson's challenge is to find the right strategy to expand the EarthEra REC program in the midst of these difficultiesThis case was written by graduate students Jenna Agins, Rajat Bhatia, Andrea Cunningham, Natalie George, Daniel Gonzalez-Kreisberg, and Jonathan Mattson, under the supervision of Professor Andrew Hoffman.

This is the first in a series of lecture notes which, if tied together into a textbook, might be entitled "Practical Regression." The purpose of the notes is to supplement the theoretical content of most statistics texts with practical advice based on nearly three decades of experience of the author, combined with over one hundred years of experience of colleagues who have offered guidance. As the title "Practical Regression" suggests, these notes are a guide to performing regression in practice. This technical note introduces students to the essential elements of convincing empirical research using regression. Students who read this note will be prepared to perform an unstructured research project. The note presents ten essential steps in research, starting with model development and ending with presentation of results. Coverage is given to important subjects such as identification and model robustness.

What is the right mix between business-driven and pure research? This case considers the question in the setting of IBM Research India, where a management push for balance between exploratory research and the fulfillment of business needs meets some resistance from employees who were accustomed to so-called pure basic research. The case looks at the Spoken Web project, a good example of use-inspired research for which management has yet to develop a viable business plan.

The chairperson of the United Church Housing Corporation (UCHC) of Regina, Saskatchewan, received some information from an external consultant who was hired to assess the state of affairs of the UCHC. This non-profit organization had operated for over 50 years and had built accommodations for many seniors that were both affordable and offered personal independence. In 2005, the UCHC board approved a new four-storey assisted living facility, Wascana Wing, which was to be built in response to long waitlists. With this decision, the UCHC board had taken out a $3 million mortgage to finance the project. Since opening the new facility, UCHC had been plagued by high vacancy rates as new for-profit competitors entered the market for senior accommodations. The combination of high vacancy rates and UCHC's highly leveraged financial position were the source of losses from 2006 to the present. The board's break-even mentality was not working. UCHC was at a major crossroads - the housing situation of more than 100 seniors residing in assisted living apartments and cottages would need to be decided upon at the next meeting. The question was whether or not June, a retired nurse, would recommend that the board proceed with winding up UCHC or make suggestions that would call for major changes to the current business model.

Datavast Inc., a product designer and manufacturer based in China, had just launched its new private cloud storage product, the Data Security Box. The general manager of Datavast was faced with the dilemma of who to sell this product to. He determined that segmenting by size was the most effective method, as customers in different industries and regions did not have very different needs or buying characteristics. However, SMEs (companies with 200-500 computers) and large companies (companies with 1,000+ computers) exhibited vastly different needs and purchasing behaviour. The general manager had limited resources, so he faced the decision of focusing on either SMEs or large companies. Although Datavast did not have any direct competitors at the time, its decision was complicated by the company's current state and capabilities, as well as the data storage industry in China. Also, the general manager was hoping to retire within five years and was unwilling to make additional capital investments in the company. Datavast was operating at a loss and his goal was to bring the company into profitability within the next year. A net loss also meant that the company could not afford to be burdened with large additional expenses. Lastly, private cloud storage was a new technology in China and the market needed to be familiarized with the concept.
