If enough vendors do it aggregate stats for that metric may not show them as outliers. You can extrapolate that the algorithms started competing around Feb This is what science is about! Curiosity, hypothesis and hard data! On the issue of algorithms driving crazy price inflation, it is all very interesting and innocent when it is a book, but it makes me wonder if there are similar forces currently pricing commodities in the financial markets given so much trading is executed by algorithms.
If they do this to more than all their book in catalogue then you know they are. It could be how Wall Street and the rest of the world economy gets destroyed one day. By people mindless using defective software. A few years ago it was really bad. And on and on. Ash, this explains it. Logged in one day and they were 6x the original price listed. Took it off my wish list. Have since bought it locally ish. At the local outlet of a major chain. What a great story! However, I did and very happy I did.
It was amazing how long it took anyone to find out about the pricing mishap and correct of it. Had you not stumbled upon this unique situation and followed it to the conclusion none of us would have known about the algorithm used by both parties in your story!
The article just fascinated me to no end and thanks so me much for shearing it! This is textbook oscillator stuff, if the factor is anything but an exact and constant 1, prices will either skyrocket or drop to nothing.
Story: 1. Forklifts shuttle the books around. The Math is suitable for a child. Price Skyrockets. Child gets tired and move onto next play-toy and parent sell back the book.
The records are shuffled around until GOLD is struck. Awesome post, Mike. This may be the way many people are actually making money on sites like Amazon. I knew fly dev bio is a narrow field, but not that narrow. Heaven help us. This happens lot more than just Amazon sellers especially when the products are not differentiated and customers look for price as a signal and the marketers lack the wherewithal to gain price leadership.
Part of his class is a pricing game play. The class will be split it into groups and told that they will be randomly matched with 2 others to compete in a market. Price is the only variable we can set. I do not want to give away the game, but you probably will be able to talk to Teck. He will have lots to say on this. She and her husband are tutors out of their home. They had an old textbook to sell on Amazon.
When someone bought it, they specifically requested that she not include an invoice with the package. She forgot, and sent one anyway. The addressee called her after receiving and asked who she was. Apparently, this person was not the buyer. The person on the other line had bought the book, listed as new condition, from someone on Amazon that was not her.
The obvious conclusion is that what happened in this story happened to my forum friend: Someone listed the book at a higher price, using their reputation to get the price so high, then bought her book when an order was placed. Link -via […]. We might see another post like this, except where someone paid negative two million dollars for something! Inevitably, there will be suggestions for avoiding this type of an issue in the future.
And sometimes it gives us books priced at over a million bucks! Maybe the prices are steganography, a coded message hidden in plain sight by embedding it in something innocuous? I suspect that the reset on April 22 was not because sanity prevailed, but because of integer overflow. The inadvertent pricing war leads to a 23 million dollar book on flies.
My wife and I were amazed it cost so much. Would make sense if it were the same kind of issue. I assume most sellers do this because it is simply impossible to do otherwise unless your inventory is very, very small.
The absurd price of this out-of-print book, first published in , was discovered by UC Berkley evolutionary biologist Michael Eisen, who went to Amazon to purchase the book. Hi Michael, Most of your assumptions are correct. Some sellers on Amazon list hundreds of thousands of titles. BTW this mimics the price of securities in speculative markets.
Michael, thanks for posting this — and for being so clear in your explanation. I still wonder about that. I can confirm that your assumption that one seller is simply listing books that other sellers are offering is correct. I used to work for a bookshop that listed its stock on Amazon. On more than one occasion we received orders from other bookshops. Do not include the shipping note or copy invoice.
They are merely using simple automatic software pricing bots that can raise or lower the price of the book based on the current lowest or highest selling price. With the pricing software you can chose to offer your copy at.
Otherwise it goes on endlessly. Also this has nothing at all to do with Amazon whatsoever. To the best of my knowledge Amazon. You should just examine the SellerEngine. The economics of The Jetsons. The science behind college football helmet stickers. Be The […].
Another possibility — I see bordeebooks has more than one listing under used editions. Today he tweeted about how he would love to make 23 million on his newest book and he linked to a blog post. After reading the post, I was amazed and enthralled by this article at how Amazon would use […]. Evidently they were using some kind of algorithm pricing software and it had some unpredicted results. Michael Eisen explains and has a screen shot; […]. A seller who made some sort of error in their formula a misplaced decimal point?
I was actually curious enough about it to write to the three venders; two wrote back and said that the listed prices were correct. Eisen theorizes that Profnath wanted to have the lowest price on the market, but not too low, thus the. Currently you can get this book about Lana Turner for almost a trillion dollars or a penny —your choice:.
Although no one really knows why one store set an algorithm of more than 1. Remove my book, buy the book for a dollar. A wonderful post. I am a longtime bookseller.
Back before book-selling on the internet the good old days there was a sub-profession among book-sellers made of of people who searched for books for clients. These search services advertised to the book-selling community through the AB Monthly.
Bookstores and book scouts read the AB and sent post cards to the search services with quotes of actual copies of the books from their stocks. Some search services also hit the phones or pounded the pavement in search of the books.
This was an honorable profession. One seller bought at retail or close to it and marked up the price. The customer was thrilled. Book-selling took to the internet and things progressively sped up. Now most of those services are gone. It is about as much work now to buy a book online as it once was to place a search with a search service. However, now, thanks to various services that support arbitrage book-selling Monsoon for example one can set up a constant flow of price adjustments on the stock that you hold.
This produces the stupid results so elegantly laid out by the author of the original post. At least one of these players is dumber than the average bear. FordMF correctly comments that once you get past a certain point in the list of sellers all that remains are these arbitragers a loathsome bunch. If Amazon had any ethics at all they would not tolerate them. However, they seem to be generating a net profit for Amazon. Once Amazon hears the word profit the word ethics drops out of their vocabulary.
There are many other venues through which one can buy books on the internet other than Amazon. Many booksellers have their own websites and you can buy direct.
I could not disagree more. There is no excuse for failing to offer a description of the condition and edition of the book that you are selling. Find a copy of the book offered by a bookseller who you can actually talk to on the phone.
Make that call. Amazon is for cheapskates and suckers. The reason reputable booksellers list their books on amazon. Mais je vous conseil fortement la […]. Well, one copy sold. Henry Hollander: This is kind of an off-topic tangent, but where Amazon is without any kind of real competition is foreign books. No other bookseller even comes close to Amazon when it comes to international distribution.

Someone should manually try and get the price as high as possible. It's like recess without all the dangerous playground […]. My remark about Amazon being for cheapskates or suckers is harsh I admit. Parnell read it as referring to sellers. That is not what I meant. I was referring to buyers. The situation for sellers is much more complex. Those who sell on Amazon are generally more savvy than those doing the buying. Amazon is absolutely the place in terms of eyeballs when it comes to books on the internet and so sellers flock there.
Amazon is great for the buyer who does not care about condition and will buy whatever the cheapest copy of the book is listed on Amazon hot deal or swindle no matter. However, for the customer who really needs the fourth edition and not the third, or the customer with a mildew allergy, or the customer who wants a giftable copy, or the customer who just wants to know what they are going to receive when they pay for their book Amazon just is not the best place to be.
Eisen offered the most elegant description of a type of nonsense that goes on on Amazon that I have yet seen. Perhaps he might be interested in the reverse phenomenon, that is, the regression of prices to near zero also due to the use of dynamic pricing software. That phenomenon is all to the pleasure of the buyer and the bane of the seller. I do not use dynamic pricing software. I also have the book listed on the website Tomfolio.
I have sold one copy on Tomfolio and as of yet none through my website. Who is wise? And there are many actors trading on the markets, and many decentral actors will cause prices to be relatively reasonable in the long run under most circumstances.
The only factor that can cause obvious mis-pricings is probably human failure. The short version: one vendor was automatically setting the sales price of a book that he was offering to be The number got up to almost 24 million before anybody noticed.
Check it out if, as either a buyer or a seller, you are tired of the Amazon insanity described here. He accused former JP Morgan analyst Daud Khan and industry colleague Paul Morland, once of analyst firm Peel Hunt, of carrying out "concerted and improper efforts to depress Autonomy's share price for their and their short-selling clients' benefit" and being "vehemently antagonistic towards Autonomy and its management.
If you struggled to get into your Gmail this morning, it wasn't just you. Unhappy users from Europe all the way to South Africa reported a significant outage. The issues kicked off at around 8. Interview New Zealand's Rocket Lab is set to launch another Electron rocket - a precursor to the rocketeer's first attempt at catching a descending booster.
The launch, dubbed "Love at First Insight", is currently scheduled for no earlier than 16 November owing to an "out of family ground sensor reading" when the launch window opened yesterday morning and has the primary objective of popping a pair of Earth-observation satellites into orbit for Black Sky.
Also featuring on the launch is Rocket Lab's latest evolution of its recovery technology. Unlike SpaceX's crowd-pleasing propulsive antics, the first stage of the Rocket Lab Electron will descend by parachute and attempt a controlled splashdown into the ocean, making it the third ocean recovery if all goes well.
The eventual plan is for a helicopter to snag the stage as it descends. This time, however, everything will be done except an attempt to catch the rocket. Facing rising demand for high-end Linux boxes but also issues supporting the software on its high-end kit, HP is trying solve the problem for customers by using Windows as a universal shim.
This feature extends to Redmond's WSL2. HP is using this to enable customers who want to do fancy GPU-accelerated stuff with Linux apps on the more familiar familiar to HP, that is basis of Windows. On Call A reader takes us back to a bygone era, when Blighty's brass inhabited wood-panelled offices, and the air was thick with pipe smoke and WW2 anecdotes. Welcome to On Call. Our story takes place in the s as the era of officers that served in the Second World War was coming to an end and computerisation was slithering into departments that had been hitherto resolutely manual.
According to a brief from analyst firm Gartner, it's "an emerging networking solution that provides services for computational tasks by sharing computing resources from multiple edge sites" and "a new type of decentralized computing solution that optimizes the efficiency of edge computing.
Let's start with the 27 flaws in the AMD Graphics Driver for Windows 10 — 18 of them rated High — because at least they're in software and Microsoft and Adobe's patch cadence means readers could be in the mood to fix code.
