Online business scams are rising because the Internet offers a perfect medium for con artists, who know that the money's in business. Companies can meet that threat with three defensive strategies.

HBR's editors searched for the best new ideas related to the practice of management and came up with a collection that is as diverse as it is provocative. The 2004 HBR List includes emergent concepts from biology, network science, management theory, and more. A few highlights: Richard Florida wonders why U.S. society doesn't seem to be thinking about the flow of people as the key to America's advantage in the "creative age." Diane L. Coutu describes how the revolution in neurosciences will have a major impact on business. Clayton M. Christensen explains the law of conservation of attractive profits: When attractive profits disappear at one stage in the value chain because a product becomes commoditized, the opportunity to earn attractive profits with proprietary products usually emerges at an adjacent stage. Daniel H. Pink explains why the master of fine arts is the new MBA. Herminia Ibarra describes how companies can get the most out of managers returning from leadership-development programs. Iqbal Quadir suggests a radical fix for the third world's trade problems: Get the World Bank to lend to rich countries so that there are resources for retraining workers in dying industries.

The music industry, described in breezy prose in John Alderman's Sonic Boom: MP3, Napster, and the New Pioneers of Music, is coming under intense pressure from Internet-based technologies that challenge traditional property rights. Industry executives are denouncing the upstarts, but Napster and companies like it are actually producing efficiency, not anarchy. To understand the full force of the Napster challenge, reviewer Clay Shirky says, one has to look beyond Sonic Boom's collage of people and events. Music has always been a business of high fixed costs and low marginal costs, and Internet technology is reducing marginal costs to practically zero. Before Napster, music industry executives assumed they would apply traditional per-unit pricing to sales over the Internet. Napster's success means the all-you-can-eat model has won. Newspaper and software publishers have already begun to adapt to this reality, and now it's the music industry's turn. This shift actually represents a big revenue opportunity for the industry, not a clear loss. Per-unit pricing imposes enormous psychological barriers to purchase, so shifting to an unlimited-access, subscription-based model will unleash pent-up demand for music. And the industry's abilities to develop and screen talent will be even more important to consumers in a Napster world.
