  1. Keith… Thank you so very much for a clear, concise, and easy to read explanation and… A full set of definitions.

    I believe I now (Really for the first time) fully understand now what Is meant by arbitrage.

    Thanks again!

  2. Keith,

    Your definition of straddle admits situations that Dr. Fischer would probably exclude, for instance, your example of the apple consumer. Taking our “humans act” view, you’ve illustrated how spreads motivate the choice of action. The consumer’s ranked preferences for apples, pears, and cash sets up two bid prices. The shopkeeper similarly posts two ask prices. Each fruit then has a “spread” within the consumer’s world view – even if the shop is not functioning as an auction market, Austrians model each human actor as engaging in an internal auction. When the consumer goes short cash and long pears it is clearly the start of an arbitrage which is resolved as she derives more consumed utility per dollar than any of her other choices.

    This apparent overloading of terminology isn’t just something done solely for the symmetry or reductionism of it (although those aren’t bad reasons) This explanation exposes the key property of arbitrage: it is the action which, when taken, closes a spread.

    The consumer’s purchase “straddles” one of those spreads. For the individual consumer the act narrows the spread considerably, right down to the fruit’s diminishing marginal utility. The higher profit (in consumer utility) from “pears on sale” should exceed what the consumer has come to expect from her apple habit, but there is probably a greater risk that the pears are “on sale” for quality reasons.

  3. Thanks for your comments.

    Greg: I agree with your assessment that a key to arbitrage is it narrows or closes a spread.

    I am somewhat amazed at how little has been said about the bid and the ask, and spreads in an economics context (traders get it more easily). Someone emailed me a while back and told me I was brilliant to come up with the idea of a separate bid and ask. He has studied Austrian economics! I wrote back and said thank you, but this comes straight from Menger.

    I think one could write a whole dissertation on arbitrage (this view of it, I am sure books have been written in mathematical finance). I don’t know why no one has.
