For Amazon, long-term growth confers two major benefits: the kind of economies of scale enjoyed by Wal-Mart and eliminating or weakening competitors. The book retailer Borders has been forced out of business and a rival, Barnes & Noble, is struggling. Best Buy, the electronics retailer, reported this week that earnings plunged 29 percent, despite higher revenue and a surge of Black Friday sales, because the chain had to cut prices and offer free shipping to compete with Amazon. Amazon inflamed many competitors this holiday season by offering extra discounts to shoppers who took mobile devices into stores and then used them to compare prices and order from Amazon.
