yes, very much so. W/computers normally everything gets

Amazon ‘robo-pricing’ sparks fears By Barney Jopson in New York

High-speed trading tools pioneered in the stock market are increasingly driving price movements on Amazon as sellers use them to undercut and outwit each other.
Prices change as often as every 15 minutes as some of the 2m sellers on the site join the online retailer in using computerised tools, often developed by former data miners at banks.
The “robo-pricing” has become a source of tension as Amazon competes with its clients but has access to their sales information and greater experience of data mining.
Amazon sellers – using third-party software – can set rules to ensure their prices are always, for example, $1 lower than their rivals’. More complex algorithms can analyse data to set prices most likely to secure a prominent position on the site.
But the tools create the risk of malfunctions similar to the 2010 flash crash, when algo trading was blamed for some US stock prices falling to near zero, then rebounding in 20 minutes.
Last year, out-of-control algorithms inflated the price of The Making of a Fly, a genetics book, to more than $23m, according to Michael Eisen, a biologist who blogged about it.
The opposite is possible. Some sellers have created dummy accounts with ultra-low prices to pull down those of rivals so they can corner a market by buying their goods, say pricing experts. That violates Amazon’s rules of conduct.
Jack Sheng of eForCity, which sells electronics accessories on Amazon, said the interaction of algorithms could trigger dangerous downward spirals. “If something is mispriced down to $1, your inventory can be cleaned out in no time,” he said.
Victor Rosenman of Feedvisor, an Israeli group that sells pricing tools to Amazon clients, said: “We took a lot of inspiration from the stock market?.?.?.? they have these learning algorithms that calibrate themselves and improve themselves. That is the idea we are following.” |
