The "higgling and bargaining of the market" has been accorded but scant attention by economists. It has apparently been regarded as a kind of irrelevance--a comedy part, at best, in the serious drama of industry and trade, never for a moment hindering the significant movement and outcome of the major action. As if to excuse the incompetence of this treatment (or as another phase of it) theory has tended to lay stress upon, and mildly to deplore, certain of the less amiable and engaging aspects of the process. The very term indeed as used by Adam Smith, imported a certain aesthetic disesteem, albeit tempered with indulgent approbation on other grounds. In Boehm-Bawerk's more modern account this approbation has given place to a neutral tolerance. A certain buyer, he says (in his discussion of simple "isolated" exchange), will give as much as thirty pounds for a horse; the horse's owner will take as little as ten pounds--these are predetermined and fixed valuations brought to the exchange negotiations and nothing that happens in the game of wits is conceived to modify them. The price will then be fixed somewhere between these limits. But how? "Here ..." we read, "is room for any amount of 'higgling.' According as in the conduct of the transaction the buyer or the seller shows the greater dexterity, cunning, obstinacy, power-of-persuasion, or such like, will the price be forced either to its lower or to its upper limit."[61] But the higgling cannot touch the underlying attitudes. Even "power of persuasion" is only one part of "skill in bargaining," with all the rest and like all the rest; if it were more than this there would be for Boehm-Bawerk no theoretically grounded price limits to define the range of accidental settlement and the whole explanation, as a theory of price, would reduce to nullity.[62] With this, then, appears to fall away all ground for a one-sided, or even a sharply two-sided, conception of the process of fixation of market-values. A "marginal utility" theory and a "cost of production" theory of market price alike assume that the factor chosen as the ultimate determinant is a fixed fact defined by conditions which the actual spatial and temporal meeting-together of buyers and sellers in the market cannot affect. In this logical sense, the chosen determinant is in each case an ante-market or extra-market fact and the same is true of the blades of Marshall's famous pair of scissors.
