The Economics of Network Industries

This is an original academic textbook for network economics. Oz Shy starts the book by making some reasonable claims on his discipline at large: scientific papers in economics are too technical and use unnecessary amounts of calculus. Though the book is very analytical and covers a wide scope of issues, prerequisites are at a considerably low level. Because the book uses game theory and logical reasoning instead of calculus, it is accessible to readers with different backgrounds. This book will be in good use at least with the students of economics and engineering.The book starts from the basic economics of networks and then analyses various networked industries from hardware to software and airlines to social interactions. Most topics stand separately on their own feet. The book ends with a compact presentation on the used game theoretical concepts as appendices. Being a texbook in economics, however, does not excuse inaccurate and sometimes clearly misleading use of technical terms. I had serious problems understanding why "software" denotes in this book to all kind of digital content including music and movies. In my mind, the word software is restricted to computer programs and associated materials. Also, building models on some specific technology, Shy continuously leaps over the problem of defining its essential features, which should (or should not) be modeled. Taking definitions of technical terms as given (by Shy) can definitely confuse at least engineering students. In overall, this book might be best characterized as an academic add-on to the well-known business book "Information Rules" by Carl Shapiro and Hal Varian. With some inaccurancies and perhaps some time-gap to real world applications, it makes a good textbook. Essential parts are timeless and presentation clear.
