One of the characteristic elements of the New Economy is the abundance of informational goods (e.g., movies, magazines, software, music, stock market services, etc.), which significantly differentiates today's digital, weightless economy from the traditional industrial economy.

In the new economic environment of information abundance, the laws of economics are not abolished, but they do change. In their book "Strategy Guide to the Networked Economy," Karl Spahiro and Hal Varian, professors at the distinguished Haas School of Business at the University of California (Berkeley), examine the economic principles governing the information economy and, more importantly, explore what these imply for business strategy.

The authors explain clearly and accurately how, in the information economy, businesses will develop pricing strategies, introduce new lines of informational products, effectively manage intellectual property rights, exploit the effects of positive feedback and lock-in, and take into account government regulations.

This is an absolutely essential book for anyone who wants to understand the logic of the digital economy and the strategies of businesses within it.
