Although social scientists generally agree that technology plays a key role in the economy, economics and technology have yet to be brought together into a coherent framework that is both analytically interesting and empirically oriented. This book draws on the tools of science and technology studies and economic sociology to reconceptualize the intersection of economy and technology, suggesting materiality—the idea that social existence involves not only actors and social relations but also objects—as the theoretical point of convergence. The contributors take up general concerns, such as individual agency in a network economy and the materiality of the household in economic history, as well as specific financial technologies such as the stock ticker, the trading room, and the telephone. Forms of infrastructure—accounting, global configurations of trading and information technologies, and patent law—are examined. Case studies of the impact of the Internet and information technology on consumption (e-commerce), the reputation economy (the rise of online reviews of products), and organizational settings (outsourcing of an IT system) round off this collection of essays.<B>Contributors:</B> Elizabeth Popp Berman, Daniel Beunza, Michel Callon, Karin Knorr Cetina, Shay David, Thomas F.
