At a Goldman Sachs technology conference, eBay CEO John Donahoe answered questions about the company's strategy and philosophy. One investor asked Donahoe: "I always worry Amazon is going to clip your growth as you go to fixed price [sellers]. Why don't I have to worry about Amazon every time you talk to a reporter?" Donahoe responded that e-commerce "is not going to be a winner-take-all market." Donahoe likened eBay to Costco, a discount retailer that competes against Wal-Mart and Target but with a "slightly different business model." "I think of us as the Costco because Costco has a strong emotional component," Donahoe said.
