In the summer of 2002, the Office of Naval Research asked the Committee on Human Factors to hold a workshop on dynamic social network and analysis. The primary purpose of the workshop was to bring together scientists who represent a diversity of views and approaches to share their insights, commentary, and critiques on the developing body of social network analysis research and application. The secondary purpose was to provide sound models and applications for current problems of national importance, with a particular focus on national security. This workshop is one of several activities undertaken by the National Research Council that bears on the contributions of various scientific disciplines to understanding and defending against terrorism. The presentations were grouped in four sessions â€" Social Network Theory Perspectives, Dynamic Social Networks, Metrics and Models, and Networked Worlds â€" each of which concluded with a discussant-led roundtable discussion among the presenters and workshop attendees on the themes and issues raised in the session.

Why has capitalism produced economic growth that so vastly dwarfs the growth record of other economic systems, past and present? Why have living standards in countries from America to Germany to Japan risen exponentially over the past century? William Baumol rejects the conventional view that capitalism benefits society through price competition--that is, products and services become less costly as firms vie for consumers. Where most others have seen this as the driving force behind growth, he sees something different--a compound of systematic innovation activity within the firm, an arms race in which no firm in an innovating industry dares to fall behind the others in new products and processes, and inter-firm collaboration in the creation and use of innovations. While giving price competition due credit, Baumol stresses that large firms use innovation as a prime competitive weapon. However, as he explains it, firms do not wish to risk too much innovation, because it is costly, and can be made obsolete by rival innovation. So firms have split the difference through the sale of technology licenses and participation in technology-sharing compacts that pay huge dividends to the economy as a whole--and thereby made innovation a routine feature of economic life. This process, in Baumol's view, accounts for the unparalleled growth of modern capitalist economies. Drawing on extensive research and years of consulting work for many large global firms, Baumol shows in this original work that the capitalist growth process, at least in societies where the rule of law prevails, comes far closer to the requirements of economic efficiency than is typically understood. Resounding with rare intellectual force, this book marks a milestone in the comprehension of the accomplishments of our free-market economic system--a new understanding that, suggests the author, promises to benefit many countries that lack the advantages of this immense innovation machine.

Can open source software—software that is usually available without charge and that individuals are free to modify—survive against the fierce competition of proprietary software, such as Microsoft Windows? Should the government intervene on its behalf? This book addresses a host of issues raised by the rapid growth of open source software, including government subsidies for research and development, government procurement policy, and patent and copyright policy. Contributors offer diverse perspectives on a phenomenon that has become a lightning rod for controversy in the field of information technology. Contributors include James Bessen (Research on Innovation), David S. Evans (National Economic Research Associates), Lawrence Lessig (Stanford University), Bradford L. Smith (Microsoft Corporation), and Robert W. Hahn (director, AEI-Brookings Joint Center).

Schumpeter's framework of creative destruction applied to the rapidly changing telecommunications and related Internet industries. More than fifty years ago, Joseph Schumpeter stated that processes intrinsic to a capitalist society produce a "creative destruction," whereby innovations destroy obsolete technologies, only to be assaulted in turn by newer and more efficient rivals. This book asks whether the current chaotic state of the telecommunications and related Internet industries is evidence of creative destruction, or simply a result of firms, governments, and others wasting valuable resources with limited benefits to society as a whole. In telecommunications, for example, wireless, IP, and cable-based technologies are all fighting for a share of the market currently dominated by older, circuit-switched, copper-terminated networks. This process is accompanied by mergers, acquisitions, bankruptcies, and investment and divestment in worldwide markets.The selections discuss the primary challenge facing firms, governments, and other players: how to exploit the opportunities created by such destructive dynamics. They highlight the importance of national regulations promoting competition and nonmonopolistic market structures, as well as the role of new technologies such as the Internet in driving down the price and speeding the diffusion of innovative products and services in telecommunications, media, electronic retailing, and other "new economy" industries.

An authoritative look at the microeconomics of entrepreneurship Entrepreneurs are widely recognized for the vital contributions they make to economic growth and general welfare, yet until fairly recently entrepreneurship was not considered worthy of serious economic study. Today, progress has been made to integrate entrepreneurship into macroeconomics, but until now the entrepreneur has been almost completely excluded from microeconomics and standard theoretical models of the firm. The Microtheory of Innovative Entrepreneurship provides the framework for introducing entrepreneurship into mainstream microtheory and incorporating the activities of entrepreneurs, inventors, and managers into standard models of the firm. William Baumol distinguishes between the innovative entrepreneur, who comes up with new ideas and puts them into practice, and the replicative entrepreneur, which can be anyone who launches a new business venture, regardless of whether similar ventures already exist. Baumol puts forward a quasi-formal theoretical analysis of the innovative entrepreneur's influential role in economic life. In doing so, he opens the way to bringing innovative entrepreneurship into the accepted body of mainstream microeconomics, and offers valuable insights that can be used to design more effective policies. The Microtheory of Innovative Entrepreneurship lays the foundation for a new kind of microtheory that reflects the innovative entrepreneur's importance to economic growth and prosperity.
