Really worth reading! [Posted on 2005-02-19]
As a graduate student in Economics having an undergraduate degree in Information Management, I pay much attention toward those "new economy" issues. The Economics of Information Technology illustrates the application of economic knowledge on information technology in an easy and clear way. As Professor Varian argues, "Many of the effects that drive the new information economy were there in the old industrial economy-you just have to know where to look." (p. 12), the authors demonstrate how to use the models we learned in microeconomics to discuss the development of information technology as well as the rationales behind intellectual property. The economics used throughout this book is pretty straightforward; anyone who has the most essential microeconomic knowledge can understand the whole book. Besides, the authors also review the most recent issues in intellectual properties and patents and then propose ideas about the reform of the patent system. This book is undoubtedly a very good introduction; furthermore, it exemplify some further applications and research directions, which would also benefit those who want to take a step further into this field.

Good enough to make it a required text [Posted on 2005-08-20]
This is a great concise treatment of the topic with footnotes sufficient to allow the interested reader to perform further research. I am seldom disappointed by Varian's work, and no exception here. This is good enough that it is now part of the required reading for my course "Economics of Technology" in the Masters of Information Management program at Washington University in St. L. - Prof. Steve Parsons

A fair introduction [Posted on 2005-12-22]
The rise of the Internet and its resulting commercialization have caused many to wonder whether the economics of the information age is governed by a different set of rules than can be found in "classical" economic treatises. If information technology is indeed different in this regard, this would be of great interest to those businesses whose goal it is to generate profits by its use. This very short book, composed of only two articles, gives a fairly good introduction to the economic issues that arise in the use of information technology. The authors in the book certainly motivate the subject well, but the length of the articles, along with the relative paucity of references, entails that the reader will have to do a lot of outside research in order to obtain a more in-depth understanding of the issues.

The author of the first article clearly believes that high-technology industries face the same market forces as any other industry, but that there are some that are of particular concern to them. Fixed costs for example are very high for information goods, but the marginal costs are very small. In addition, intellectual property is very important to the high-tech industry.

The Internet "boom" has become the paradigmatic example of the economics of information technology due to the speed in which the Internet took hold in business all around the world and in the "wild" speculation that took place in dot.com companies in the late nineteen-nineties. The author claims that the large increase in the NASDAQ during this time is evidence of the efficacy of competition, but he does not offer detailed evidence for this claim. When discussing the reasons behind the Internet financial "bubble" he also annoys the reader somewhat by referring to the differences between "rational" investors and "real people". It would be difficult he believes to cause a financial bubble with the former class but relatively easy with the latter. There is however no evidence for this view, from either historical data or from simulation studies. This reviewer knows of no study that is able to distinguish between a `rational investor' and a `real person' in terms of their ability to cause a financial bubble. It would be difficult in and of itself to arrive at criteria that would distinguish the two classes. It would be even more difficult to collect historical data to indeed show their behavior is different in the financial markets.

The author interprets the Internet boom as an example of what he calls "combinatorial innovation." This characterizes an historical period where a collection of technologies emerges whose components can be combined to form new products. Innovators cause a technology boom by working through all the possibilities in these components. This would seem to be a plausible explanation of the Internet boom, but it is one that would need to be examined with more care. The designation of a product as being innovative or an idea as being creative is difficult, as patent officials will attest to wholeheartedly. In addition, innovation must also be correlated with utility, in that products must be useful to the individuals or businesses that are using them. And arriving at a sound notion of creativity and innovation is also very important to those who want to automate these processes. If information technology can itself be trained (or "programmed") to create useful products, this would be very significant economically (possibly resulting in another technological "boom"), and would have major ramifications for employment and productivity.

The second article of the book is concerned with the economics of intellectual property in information technology, with particular emphasis on the role that it plays in the competitive strategies of IT firms. Legal issues are discussed in various places in the article, giving some insight into their complexity. The authors discuss the current schism between the `incentives' school, which emphasizes the ability of innovators to claim financial awards for their creations, and the `openness' school, which emphasizes the role of open (and essentially free) development in the public domain. There have been few empirical studies done on resolving which one of these approaches is optimal in terms of the creation of wealth or the creation of social benefit.

In discussing the issue of whether the patent system can provide any incentives for a private firm to make a commitment to innovation and research, the authors outline a simple mathematical (static) model to illustrate the tradeoffs that are involved. The results of this model indicate that the patent system will not offer sufficient incentives for investors. The authors point out however that this model is too simplistic to model the real issues involved in the economics of the patent system, and that a dynamic model would reveal that patent holders are able to obtain rewards that are much greater than the social contributions they make. They do not discuss this model at any length, nor give references to the "large literature" they claim exists on patent system economics. One would like to know for example what the dependence of the incentive is on the lifetime of the patent; whether a patent system can be optimized with respect to all industries, i.e. whether it can ensure optimal incentives regardless of the products offered; the degree to which patents have to be original or "creative" in order for incentives to be optimal; whether empirical studies have been done that indicate vulnerabilities to patent issuing; and whether a company can exist solely by innovation and the resulting licensing of patents.

intro to economics of information technology [Posted on 2008-09-23]
In this little book (only 102 pages long) Hal Varian, Google's Chief Economist, and his colleagues, all three at UC Berkeley, tackle with ease a difficult topic for the general reader. In the benchmark model of competition all economic agents have perfect sight of, and easy access to, information. There are no profit incentives to hide information that everyone already have. The Economics of Information Technology exposes the weaknesses of such a model. The intellectual property rights system is reasonably strong in dealing with information technology goods. However, "copyright law is critical in the information content industries...." Such law tends to be restrictive. Information is by nature a common good, beset by the tragedy of the commons. The topic is pretty dense, but the benefits from reading this book are enormous. Besides, because it is a short book, the reader can always re-read it. Highly recommended!!
