Written by economists Carl Shapiro and Hal Varian, Information Rules: A Strategic Guide to the Network Economy offers readers practical guidelines for understanding and working within the new "network economy." The book addresses matters of concern to public policy analysts, corporate economists, and educators alike. By applying traditional economics concepts to new economic models, the authors suggest compelling ways of navigating the nuanced world of information technology.
Included in Shapiro and Varian's discussion are broad overviews describing and defining the information economy; business strategies that deal directly with the hardware, software, and online industries; information related to pricing and version upgrades; copyright law; managing lock-in; and other topics pertinent to information technology economics. Comparing newer corporate giants like Microsoft to old-world technology bulwarks like Edison, Shapiro and Varian demonstrate how economic theories do not need to shift dramatically to account for the quirks of information technologies. In Information Rules, the authors illustrate how, in spite of enormous changes in the economy, "the basic laws of economics asserted themselves" (Ch. 1 Overview, 1st para.). Therefore, students of economics should be able to grasp the concepts presented in the book without straying too far from traditional economic theories.
Despite enormous advancements in technologies and technological infrastructures, the core principles of economics still push and pull at the market. For example, the authors note that "the old industrial economy was driven by economies of scale; the new information economy is driven by the economics of networks" (Ch. 7 Overview, 3rd para.). At the same time, the authors proceed to describe network economy theories and survival strategies that are grounded in familiar economic principles.
Similarly, temporary monopolies have replaced the oligopolies of old, and companies now contend with standards wars and technological compatibility instead of inflexible supply and demand curves. However, public policy reflects the same core values and legal principles that have guided technology businesses since Bell. The authors also show the codependent relationship between the software and hardware industries — one of the distinguishing features of the network economy is the interconnectedness of all market sectors. In order for organizations to survive within a network economy, corporations must anticipate upcoming technology changes, and both software and hardware manufacturers need to keep abreast of developments across all information technology sectors.
Information is defined by Shapiro and Varian as "anything that can be digitized" (Ch. 1 "Information" para. 1). As opposed to hard commodities, information involves "rather unusual" cost structures (Ch. 1 "Information" para. 2). Therefore, in order to understand the network economy, it is essential to understand core concepts of cost structures related to information. Shapiro and Varian note that information is relatively expensive to produce initially but relatively cheap to reproduce, meaning that cost structures must account for the initial production stage.
Ways that organizations deal with pricing include identifying key markets and altering prices based on version upgrades or demand-based services. This approach to versioning and differential pricing is one of the book's most practically useful contributions for businesses operating in information markets.
