(85,373 posts)8. Three Expensive Milliseconds PAUL KRUGMAN
http://www.nytimes.com/2014/04/14/opinion/krugman-three-expensive-milliseconds.html
Four years ago Chris Christie, the governor of New Jersey, abruptly canceled Americas biggest and arguably most important infrastructure project, a desperately needed new rail tunnel under the Hudson River. Count me among those who blame his presidential ambitions, and believe that he was trying to curry favor with the government- and public-transit-hating Republican base.
Even as one tunnel was being canceled, however, another was nearing completion, as Spread Networks finished boring its way through the Allegheny Mountains of Pennsylvania. Spreads tunnel was not, however, intended to carry passengers, or even freight; it was for a fiber-optic cable that would shave three milliseconds three-thousandths of a second off communication time between the futures markets of Chicago and the stock markets of New York. And the fact that this tunnel was built while the rail tunnel wasnt tells you a lot about whats wrong with America today.
Who cares about three milliseconds? The answer is, high-frequency traders, who make money by buying or selling stock a tiny fraction of a second faster than other players. Not surprisingly, Michael Lewis starts his best-selling new book Flash Boys, a polemic against high-frequency trading, with the story of the Spread Networks tunnel. But the real moral of the tunnel tale is independent of Mr. Lewiss polemic.
Think about it. You may or may not buy Mr. Lewiss depiction of the high-frequency types as villains and those trying to thwart them as heroes. (If you ask me, there are no good guys in this story.) But either way, spending hundreds of millions of dollars to save three milliseconds looks like a huge waste. And thats part of a much broader picture, in which society is devoting an ever-growing share of its resources to financial wheeling and dealing, while getting little or nothing in return.
