Given a set of alternatives, a set of consequences, and a correspondence between those sets, decision theory offers conceptually simple procedures for choice. This book presents an overview of the fundamental concepts and outcomes of rational decision making under uncertainty, highlighting the implications for statistical practice.

Conclusion -- Appendix: A Note on the Literature on HFT -- Notes -- References -- Index"Trading at the Speed of Light tells the story of how many of our most important financial markets have transformed from physical trading floors on which human beings trade face-to-face, into electronic systems within which computer algorithms trade with each other. Tracing the emergence of ultrafast, automated, high-frequency trading (HFT) since the early 2000s, Donald MacKenzie draws particular attention to the importance of what he deems the 'material political economy' of twenty-first century finance. Fast transmission of price data used to involve fibre-optic cables, but the strands in such cables are made of materials (usually a specialised form of glass) which slow light down to around two-thirds of its speed in free space. By contrast, microwave and other wireless signals used in HFT travel through the atmosphere at nearly full light speed. At these nanosecond speeds, the physical nature of information transmission and the precise spatial location of the equipment involved become hugely important, thus creating inevitable pinch points in the system. MacKenzie details the ways in which these pinch points - individual frequency bands, specific locations on the roofs of computer data centres, and particular sites for microwave towers - are especially advantageous, making it possible for those who control them to profit from that control. The book draws from over 300 interviews conducted with high-frequency traders around the world, the people who supply them with technological systems and communication links, exchange staff and regulators, as well as with others who function within markets that have not yet become dominated by HFT. MacKenzie focuses most closely upon the four main sites of international HFT - Chicago, New York, Amsterdam, and London - and examines both the technology and the politics underpinning modern financial markets"--Provided by publisher.InvestmentsData processingProgram trading (Securities)AlgorithmsStock exchangesFinanceAlexandre Laumonier.Automated Trading Desk.BrokerTec.CME.Chicago Mercantile Exchange.Dark Pools.E-Mini.EBS.Flash Boys.Juan Pablo Pardo-Guerra.Michael Durbin.Michael Gorham.Michael Lewis.Nidhi Singh.Scott Patterson.eSpeed.electronic order books.financial trading.foreign exchange.futures.geodesic.liquidity taking.market making.material political economy.materiality.political economy.science and technology studies.share trading venue.shares.social studies of finance.sociology of finance.sovereign bonds.speed bumps.InvestmentsData processing.Program trading (Securities)Algorithms.Stock exchanges.Finance.332.60285416MacKenzie Donald A.464054MiAaPQMiAaPQMiAaPQBOOK9910554220003321Trading at the speed of light2818759UNINA00987nam0 22002411i 450 UON0039538220231205104632.64820110707d1978 |0itac50 baitaIT|||| |||||Per una politica locale dei servizi socialila lunga marcia di avvicinamento all'Unità localeCarlo Trevisan. - Bolognail Mulino, c1978181 p.21 cm.001UON004040422001 Studi e ricerche82ITBolognaUONL000085TREVISANCarloUONV203335109405Il MulinoUONV245824650ITSOL20240220RICASIBA - SISTEMA BIBLIOTECARIO DI ATENEOUONSIUON00395382SIBA - SISTEMA BIBLIOTECARIO DI ATENEOSI VI DIR PUB D 0087 SI SC 5473 5 0087 BuonoPer una politica locale dei servizi sociali430147UNIOR
