  Bill & Melinda Gates Foundation: Shaping the Vaccine Manufacturing Ecosystem (Abridged)

  Willy C. Shih

  This case describes the efforts of the Bill & Melinda Gates Foundation to lower the cost of producing vaccines to prevent polio infections. It is an abridged version of HBS Case No. 620-021 with less emphasis on comparison between traditional and the new compact modular process developed with the Foundation's funding. It focuses more on the lowering of entry barriers to vaccine manufacture and some of the perceived risks associated with that.

  Dollar General (A)

  Willy Shih, Stephen P. Kaufman and Rebecca McKillican

  Dollar General Corporation (DG) operates one of the leading chains of extreme value retailers in the United States. 2006 revenues reached $9.2 billion, making DG the 6th largest mass retailer in the country. With revenues growing at 9% annually over the five-year period up to 2005, DG had the distinction of being only one of three retailers to outperform Wal-Mart in both revenue and profit growth in that time. Life in a Dollar General store paints a vivid picture of the roots and historical focus of the company. Opportunistic buying has given the stores an eclectic merchandise mix. Analysts often referred to this category as "treasure hunt" SKUs. Offers an opportunity to examine a company's business model, particularly since DG has been so successful competing with Wal-Mart where so many other retailers have not. While it started out as a family business in the five-and-dime tradition, it evolved to a close-out retail model where its unique low-overhead operations were advantageous. As it added highly consumable categories its mix shifted, but it managed to retain its low-overhead model. Interestingly, the mix shift was likely more an emergency strategy driven by store-level operations than by top-down driven strategy. Frames the growth options available to DG's CEO as he grapples with how to maintain growth.

  Myanmar: Special Economic Zones

  Willy Shih and Dawn Lau

  This case examines four Special Economic Zones in Myanmar. While the country's development had been hobbled by a complex history of military rule, ethnic conflict, and international sanctions, as it pursued liberalization it sought avenues to developing its economy. The four zones described in the case – Dawei, Kyaukphyu, Thilawa, and the New Yangon City project all had different roots and different motivations. The different rates of progress of each reflected the interests and approaches of each of the projects' participants.
