      Couldn't this be turned around by making false online identies? Tailoring it to garner the best prices?

      Yes, it could, thus the only reason I don't really feel all that concerned about the possibility of vastly different prices for different people.

      Not just online, though, but more importantly, in the real world as well. From the article, for example, it talks about the diehard Coke drinker paying twice as much because the company will exploit his preference. Easy solution? Find a similarly diehard Pepsi fan, and each buy the other's soda for them. So both pay less than the mean rate, as the respective companies try to lure each over to their own product with extremely discounted prices.

      Now, in some situations this wouldn't work. But for anything costing more than a few bucks (electronics, for example), "shopping around" would go from "check pricewatch" to "ask grandma (or someone who would normally have significantly different buying habits than yourself) how much she can get that great new toy for".

    I suspect that this field will become increasingly important in the years ahead. One problem (from the supplier side) in the current economy is the lack of pricing power available to boost earnings. Partly due to influences like the availability of product information on the web, consumers are more willing and able to find the best deal on a given item, rather than just march down to the store and pay MSRP.

    People also have to realize that price descrimination is and has been all around us for a very long time. Coupons, "daily specials", business-class travel, etc. are all examples of this. There should be plenty of opportunities to increase price descrimination without impacting customer privacy (i.e. the temperature-sensitive drink machine in the article).

    It is not at all similar to price fixing. Price fixing occurs if competitors get together and agree on a price for their product. Therefore, competition is eliminated. This is a cartel and illegal under all antitrust laws know to me. Price fixing also occurs in other circumstances, when, for example a producer sets a minimum (or maximum) price at which a retailer is allowed to sell its product.

    On the other hand, a company is price discriminating if it sells the same product at different prices. In many circumstances, this is entirely legal.

    Why price discriminate?

    Imagine a company selling product X. There are three different consumers, A, B and C. A values X at EUR50, B at EUR100 and C at EUR200.

    In a market where the company is unable to distinguish these customers, it can only sell the item to each customer at the same price. If it sells at EUR50, all three customers will buy, if it sells at EUR150, only customer C will buy.

    Therefore, the company has every incentive to price differentially, optimally EUR50 to A, EUR100 to B and EUR200 to C.

    Two problems: (1) The company will have to find out about the valuations. (2) The possibility of trading amongst the customers limits price discrimnation (A buys at EUR50 and sells on to C at a higher price).

    (1) is usually not solved perfectly. Price discrimination is usually applied across different groups that can be identified (ie customers in country A vs customers in country B or students vs non-students). However, the article describes how technology can be used to achieve perfect price discrimination.

    (2) Either the characteristics of the product are such that trading is impossible (ie personalised products) or difficult (high transaction costs). Alternatively, the company could prevent trading by using contracts or other competitive threats. This could be illegal under some circumstances.

Limited monopolies can be created through brand IDs, location, government franchise, patent and copywrite, being first to market, and so forth.

    I would say that there are at least 3 different forms of targeted pricing, none of which are that bad for the consumer:

    • The "Used Car Salesman" Technique: The Used Car Salesman has a listed price, and a "bottom line" price which is his minimum profit. He's never going to let you know the bottom line. If you want to take the list price, that's fine by him - maximum profit. If you want to haggle it down, he's going to haggle you back in a number of ways; value of your trade-in, financing available, etc., but if you try to undercut his bottom line, end of conversation. This is targetted in that the UCS is going to base his arguments and approach based on what he thinks you are willing to pay, even though you may be trying to go cheaper than this.
    • The "Preferred List" Technique: This is the one that really rankles people most, since it implies that somebody else is getting a benny that you aren't. When you find out that Mr. Jones across the street gets a catalog with lower prices just because he's in a different demographic segment, there's a certain amount of jealousy that "he's saving $5 where you aren't, therefore that company is giving him $5." Nothing could be further from the truth. Mr. Jones is only being marketed to more aggressively. Also, it's a staple of capitalism that the money exchanged for a product is valued by the seller more highly than the product being bought, and vice versa. Otherwise, why would the transaction take place? Therefore, the "loss" that the consumer feels by paying a higher price than another is really just a form of covetousness, since they can avoid the "loss" by simply declining to purchase.
    • The Auction Technique: Obviously we see this all over the place on eBay and Priceline, but it is also a form of targeted pricing. Rather than relying upon some classification of the customer to try to determine their "willing to pay" price, the customer is encouraged to volunteer it. There is still a "bottom line" as in the UCS Technique, which is enforced by Reserve prices or by declining to transact after the auction. However, the customer is quite often willing to pay the same higher price that they would be rankled by in another marketing method, due to some form of "gambling frenzy" that overrides the psychology of "perceived loss". In reality, the customer is just becoming honest about what they are able and willing to pay, or what is an acceptable value proposition.


    To wit: imagine the "Preferred List" technique, where you and Mr. Jones receive a catalog. There is a product which normally lists for $700, but Mr. J's catalog has it for $500, where your catalog has it for $600. This is unfair. However, imagine being in an online auction for the same product. He bids $500, you bid $600. You win, AND you save money.

    The only difference is that you feel superior in the auction method due to beating a number of people, whereas in the Preferred list method, you feel inferior due to being excluded from a perceived "gift".
