Donald MacKenzie – författare

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 "futures." 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 world''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 mainstream—chaos theorist Benoit Mandelbrot''s model of "wild" randomness. MacKenzie''s pioneering work in the social studies of finance will interest anyone who wants to understand how America''s financial markets have grown into their current form.

"....sets a remarkably high standard in breadth of coverage, in scholarship, and in readability and can be recommended to the general reader and to the specialist alike." - Science and Society

"....This remarkably readable and well-edited anthology focuses, in a wide variety of concrete examples, not on the impacts of technologies on societies but in the reverse: how different social contexts shaped the emergence of particular technologies." - Technology and Culture

The book draws on authors from Karl Marx to Cynthia Cockburn to show that production technology is shaped by social relations in the workplace. It moves on to the technologies of the household and biological reproduction, which are topics that male-dominated social science has tended to ignore or trivialise - though these are actually of crucial significance where powerful shaping factors are at work, normally unnoticed. The final section asks what shapes the most frightening technology of all - the technology of weaponry, especially nuclear weapons.

The editors argue that social scientists have devoted disproportionate attention to the effects of technology on society, and tended to ignore the more fundamental question of what shapes technology in the first place. They have drawn both on established work in the history and sociology of technology and on newer feminist perspectives to show just how important and fruitful it is to try to answer that deeper question. The first edition of this reader, published in 1985, had a considerable influence on thinking about the relationship between technology and society. This second edition has been thoroughly revised and expanded to take into account new research and the emergence of new theoretical perspectives.

Around the globe, economists affect markets by saying what markets are doing, what they should do, and what they will do. Increasingly, experimental economists are even designing real-world markets. But, despite these facts, economists are still largely thought of as scientists who merely observe markets from the outside, like astronomers look at the stars. Do Economists Make Markets? boldly challenges this view. It is the first book dedicated to the controversial question of whether economics is performative--of whether, in some cases, economics actually produces the phenomena it analyzes. The book''s case studies--including financial derivatives markets, telecommunications-frequency auctions, and individual transferable quotas in fisheries--give substance to the notion of the performativity of economics in an accessible, nontechnical way. Some chapters defend the notion; others attack it vigorously. The book ends with an extended chapter in which Michel Callon, the idea''s main formulator, reflects upon the debate and asks what it means to say economics is performative. The book''s insights and strong claims about the ways economics is entangled with the markets it studies should interest--and provoke--economic sociologists, economists, and other social scientists. In addition to the editors and Callon, the contributors include Marie-France Garcia-Parpet, Francesco Guala, Emmanuel Didier, Philip Mirowski, Edward Nik-Khah, Petter Holm, Vincent-Antonin Lépinay, and Timothy Mitchell.

A remarkable look at how the growth, technology, and politics of high-frequency trading have altered global financial marketsIn today’s financial markets, trading floors on which brokers buy and sell shares face-to-face have increasingly been replaced by lightning-fast electronic systems that use algorithms to execute astounding volumes of transactions. Trading at the Speed of Light tells the story of this epic transformation. Donald MacKenzie shows how in the 1990s, in what were then the disreputable margins of the US financial system, a new approach to trading—automated high-frequency trading or HFT—began and then spread throughout the world. HFT has brought new efficiency to global trading, but has also created an unrelenting race for speed, leading to a systematic, subterranean battle among HFT algorithms.In HFT, time is measured in nanoseconds (billionths of a second), and in a nanosecond the fastest possible signal—light in a vacuum—can travel only thirty centimeters, or roughly a foot. That makes HFT exquisitely sensitive to the length and transmission capacity of the cables connecting computer servers to the exchanges’ systems and to the location of the microwave towers that carry signals between computer datacenters. Drawing from more than 300 interviews with high-frequency traders, the people who supply them with technological and communication capabilities, exchange staff, regulators, and many others, MacKenzie reveals the extraordinary efforts expended to speed up every aspect of trading. He looks at how in some markets big banks have fought off the challenge from HFT firms, and how exchanges sometimes engineer technical systems to favor certain types of algorithms over others.Focusing on the material, political, and economic characteristics of high-frequency trading, Trading at the Speed of Light offers a unique glimpse into its influence on global finance and where it could lead us in the future.
