The Economics of Information Technology is a concise and accessible review of some of the important economic factors affecting information technology industries. These industries are characterized by high fixed costs and low marginal costs of production, large switching costs for users, and strong network effects. These factors combine to produce some unique behavior. The book consists of two parts. In the first part, Professor Varian outlines the basic economics of these industries. In the second part, Professors Farrell and Shapiro describe the impact of these factors on competition policy. The clarity of the analysis and exposition makes this an ideal introduction for undergraduate and graduate students in economics, business strategy, law and related areas.

A detailed analysis of Schumpeter's legacy and the impact of his thought on both theory and empirical work

It once took two decades to replace one-third of the Fortune 500; now a subset of new firms are challenging and displacing this elite group at a breathtaking rate, while armies of startups come and go within just a few years. Most new jobs are, in fact, coming from small firms, reversing the trend of a century. David Audretsch takes a close look at the U.S. economy in motion, providing a detailed and systematic investigation of the dynamic process by which industries and firms enter into markets, either grow and survive, or disappear. He shapes a clear understanding of the role that small, entrepreneurial firms play in this evolutionary process and in the asymmetric size distribution of firms in the typical industry.Audretsch introduces the large longitudinal database maintained by the U.S. Small Business Administration that is used to identify the startup of new firms and track their performance over time. He then provides different snapshots of the process of industries in motion: why new-firm startup activity varies so greatly across industries; what happens to these firms after they enter the market; the extent to which entrepreneurial firms account for an industry's economic activity and why that measure varies across industries; how small firms compensate for size-related disadvantages; and who exits and why.Audretsch concludes that the structure of industries is characterized by a high degree of fluidity and turbulence, even as the patterns of evolution vary considerably from industry to industry. The dynamic process by which firms and industries evolve over time is shaped by three fundamental factors: technology, scale economies, and demand. Most important, the evidence suggests that it is the differences in the knowledge conditions and technology underlying each specific industry -- key elements in innovation -- that are responsible for the pattern particular to that industry.

The past two decades have seen a gradual but noticeable change in the economic organization of innovative activity. Most firms used to integrate research and development with activities such as production, marketing, and distribution. Today firms are forming joint ventures, research and development alliances, licensing deals, and a variety of other outsourcing arrangements with universities, technology-based start-ups, and other established firms. In many industries, a division of innovative labor is emerging, with a substantial increase in the licensing of existing and prospective technologies. In short, technology and knowledge are becoming definable and tradable commodities. Although researchers have made significant advances in understanding the determinants and consequences of innovation, until recently they have paid little attention to how innovation functions as an economic process. This book examines the nature and workings of markets for intermediate technological inputs. It looks first at how industry structure, the nature of knowledge, and intellectual property rights facilitate the development of technology markets. It then examines the impacts of these markets on firm boundaries, the division of labor within the economy, industry structure, and economic growth. Finally, it examines the implications of this framework for public policy and corporate strategy. Combining theoretical perspectives from economics and management with empirical analysis, the book also draws on historical evidence and case studies to flesh out its research results.

Technology, Market Structure and Internationalization discusses the domestic and external factors that impinge upon the process of technological capability building in developing countries and draws policy implications. Specifically, it examines the interaction between technological effort in developing countries. Providing fresh insights, this volume will be of interest to researchers in development economics as well as to those involved with the creation of policy in developing countries.

This book introduces upper-level undergraduates, graduate students, and researchers to the latest developments in network economics, one of the fastest-growing fields in all industrial organization. Network industries include the Internet, e-mail, telephony, computer hardware and software, music and video players, and service operations in the banking, legal, and airlines industries among many others. The work offers an overview of the subject matter as well as investigations about specific industries. It conveys the essential features of how strategic interactions between firms are affected by network activity, as well as covering social interaction and its influence on consumers' choices of products and services. Virtually no calculus is used in the text, and each chapter ends with a series of exercises and selected references. The text may be used for both one- and two-semester courses.

Technical advance requires resources and is motivated by the quest for profits; therefore, the rate and direction of advance is determined by the economic system. Recognition of this fact has focused attention on the performance of the market economy in the allocation of resources to technical advance, and the consequent body of research is surveyed and synthesised in this book. The theories of market structure and innovation proposed by Schumpeter, Galbraith, Arrow, Schmookler, Scherer, Mansfield, Phillips, Barzel, Kamien and Schwartz, Loury, Nelson and Winter, Grabowski, Dasgupta and Stiglitz, and others are presented in an integrated form. These theories deal with the nature of competition, the incentives to innovate and the pace of innovative activity under different market structures, and the existence of a market structure that yields the most rapid rate of innovation. In addition, the findings of seventy empirical studies dealing with various facets of the microeconomics of technical innovation are presented. The book is designed to be accessible to economists working in a variety of situations - in universities, business and government - and who are concerned with questions of technical innovation. It is also suitable for senior-level undergraduates and first year graduate students approaching the subject in a comprehensive way for the first time.
