Passage 3
The digital revolution, as exemplified by the Internet and electronic commerce, has shaken mark1eting practices to their core.  In a recent paper, Whartons Jerry Wind, director of the SEI Center for Advanced Studies in Management, and co-author Vijay Mahajan, a marketing professor at the College of Business Administration of the University of Texas at Austin, examine the impact of digital marketing on concepts like pricing, when customers can propose their own prices (priceline.com), or buyers and sellers can haggle independently in auctions (eBay.com).
The paper provides an overview of some of the emerging realties and new rules of marketing in a digital world, and outlines what the new discipline of marketing may look like in the early part of the new century.
