New Fundamental Law of Network Economics 106

intersys writes "A new fundamental law of economics has been formulated by Rod Beckstrom, former Director of the National Cyber Security Center. In Words: The value of a network equals the net value added to each user's transactions (PDF) conducted through that network, valued from the perspective of each user, and summed for all. It answers the decades-old question of 'how valuable is a network.' It is granular and transactions-based, and can be used to value any network: social, electronic, support groups, and even the Internet as a whole. This new model or law values the network by looking from the edge of the network at all of the transactions conducted and the value added to each. One way to contemplate the value the network adds to each transaction is to imagine the network being shut off and what the additional transactions' costs or loss would be. Beckstrom's Law replaces Metcalfe's law, Reed's law, and other concepts which proposed that the value of a network was based purely on the size of the network (and in the case of Metcalfe's law, one other variable)."

      On one hand, you have to put it in context. There have been several models of network value, and none of them have taken this "common sense" approach of defining value in terms of what you get out of the network.

      But before running with that, we have to look at the other hand, and see why none of the older models take this approach. I think it comes down to the question of "what is the model's purpose"? The simplicity and usability of a model are potentially as important as its accuracy.

      If I can't predict the inputs to my model, then my model can't be used for prediction. I can predict a certain level of information about a hypothetical network using size-based models.

      Moreover, if I can't measure the inputs to my model, then I can't use it at all. Claims that we can "measure the value of the Internet" are a bit much.

      Don't get me wrong, this model may be well-suited to some purposes. But it does not, as TFS claims, "replace" the existing models any more than relativity "replaces" classical physics. Sure, it may be a highly accurate definition of the value of a network when you can observe that network empirically (but a definition is not a "law"). This assumes that it accounts for negative value of a transaction, though. (What is the contribution of spam to the value of the Internet?)

      • (What is the contribution of spam to the value of the Internet?)

        For the spammer it is placed squarely in the plus column.

        No, he lays it all out right there for us:

        the value of a network equals the net value added to each user's transactions... It... can be used to value any network... even the Internet as a whole

        See? So I'll just start adding. Once I get done quantifying the value of every transaction I've ever performed over the internet, I'll start on yours next. So can you email my your entire history of internet usage (including the email itself) and I'll get to it when I finish mine, in about... one hundred years. Following this model, I may finish tabulating the current value of the internet sometime before the heat death of the universe.

    • Exactly. If the article summary is accurate, this seems to just take the centuries-old theory of subjective value and applies it to an economy characterized by a network. Network economics must be in a sad state if it's taking so long for the basics to just be "discovered".

    I think this definition is pretty damn useless -- how is one supposed to calculate this value for anything but trivial example cases? You would have to determine the value of each transaction, and then the 'value-add' of the network for that transaction, as determined by the user. I make 'transactions' (financial and otherwise) on the Internet all the time, and I couldn't begin to guess at useful values for these. And I'm just one of millions of such users.

    Finally, how would one even begin to define 'value' for the transactions in a social network? How much (or little!) is being poked worth?!?

      One word: Statistics.

      You are right, though, about the value of a social network. But this is not a problem of appraising internet, it is a much older issue which has to do with foundations of economics. It falls into a wide category which one writer calls "shadow work". An extreme example is the work of a parent at home, raising a child. The economic worth to the society is tremendous, but no one gets paid for it. Likewise, a person may produce tremendous value by simply connecting the right people with each other, but there is no easy way to put a price sticker on it, simply because there is no money exchange.

      It may be to the best. I personally like the fact that we have other economies besides the one based on money.

    Beckstrom:

    = Sum(i=1..n,Sum(k=1..n, B(i, k) - C(i, k))).

    Vj = Sum(i=1..n, Sum(z=1..n, Ai))
    = Sum(i=1..n, n*Ai)
    = n* Sum(i=1..n, Ai)

    Value is an ill-defined term, and different observers will value the same transaction differently. This isn't only because it's ill-defined, but also because valuation is observer centric.

    Because of this the law is both too vague to be useful, and silly. Many observers will only value some of the transactions. Others will value some of the transactions negatively. Etc.

    E.g., what is the value of the advertisement that may appear at the top of this page? To slashdot it's valued as a source of income. To the advertiser it's valued as a way of attracting business. To most readers it's ignored. To some readers it's a nuisance. Each means of valuing the ad gives it a different valuation...and each valuation is clearly observer-centric.

  • I'm no fancy expert like this guy, but here are two obvious problems that invalidate the theory as far as I'm concerned:

    1. It's impossible to measure. Ergo, it's useless.

    2. There is value in potential uses, not just actual transactions. For example, how much is 911 service worth? Zero until you break your arm? No. There is a value in knowing that you can reach 911, regardless of whether you use it. Similarly, networks provide value by creating opportunity, even if that opportunity is unrealized.

  • "The value of a network equals the net value added to each user's transactions"

    -----So, if I build a $25,000,000 computing center, and 1,000,000 people make searches for porn, then each search was worth $25?

    I don't think so.

    What determines a network's value is:

    1. Quality of network hardware,
    2. Quality of network software,
    3. Network speed,
    4. Network efficency.

    However, this is just the value of the network.

    The value of each transaction is dependent on the transaction's criticality value to the user, with 'cri

  • The problem with this kind of model if that it give a value in such a way that business men can start to calculate how much they should charge for a given pipe, even the pipe to your house. Quantizing everything, giving it value. Well to do that you have to Identify each kind of thing over that pipe, which means they have to know what each thing is, its type, its size, track on it save its value.

    Two problems. The cost of doing that and saving that intformation is huge. Of course that would be factored into

    2. SAVING Cash is BAD
    3. SPENDING Cash is UGLY
  • Great, its defined by the 'transactions'. So what is a transaction? The intellectual value gained from reading a website? Credit card values charged? Advertisement revenues? Bandwidth use?
