In An Engine, Not a Camera, Donald MacKenzie argues that the emergence of modern economic theories of finance affected financial markets in fundamental ways. These new, Nobel Prize-winning theories, based on elegant mathematical models of markets, were not simply external analyses but intrinsic parts of economic processes.

Paraphrasing Milton Friedman, MacKenzie says that economic models are an engine of inquiry rather than a camera to reproduce empirical facts. More than that, the emergence of an authoritative theory of financial markets altered those markets fundamentally. For example, in 1970, there was almost no trading in financial derivatives such as andquot;futures.andquot; By June of 2004, derivatives contracts totaling $273 trillion were outstanding worldwide. MacKenzie suggests that this growth could never have happened without the development of theories that gave derivatives legitimacy and explained their complexities.

MacKenzie examines the role played by finance theory in the two most serious crises to hit the worldandrsquo;s financial markets in recent years: the stock market crash of 1987 and the market turmoil that engulfed the hedge fund Long-Term Capital Management in 1998. He also looks at finance theory that is somewhat beyond the mainstreamandmdash;chaos theorist Benoit Mandelbrot's model of andquot;wildandquot; randomness. MacKenzie's pioneering work in the social studies of finance will interest anyone who wants to understand how Americaandrsquo;s financial markets have grown into their current form.

andquot;Donald MacKenzie has long been one of the world's most brilliant social and historical analysts of science and technology. Here he provides an original, astute, and exhaustively researched account of the development of finance theory and the ways in which it is intertwined with financial markets. An Engine, Not a Camera is essential for anyone interested in markets and the forms of knowledge deployed in them.andquot;

andquot;Having returned from an audacious incursion into the black box of modern financial markets, Donald MacKenzie shows how economic theory has succeeded in capturing and shaping them. This book will be of substantial interest to specialists in a range of fields including economics, finance theory, economic sociology, and science and technology studies. But MacKenzie's tour de force is to make clear, even to nonspecialists, that through complex technical issues, alternative forms of economic organization can be imagined and discussed.andquot;

andquot;An Engine, Not a Camera is a compelling, detailed, and elegantly written exploration of the conditions in which finance economists help to make the world they seek to describe and predict. Donald MacKenzie has long been without equal as a sociologist of how late modern futures are brought into being and made authoritative. This is his best work yet.andquot;
