			[[F.A. Hayek]] argues that the theory of perfect competition has little claim to be called "competition" at all, and that its conclusions are of little use as guides to policy. None of the devices adopted in ordinary life for what is normally understood as competition would still be open to a seller in a market in which so-called "perfect competition" prevails.

			Advertising, undercutting, and improving ("differentiating") the goods or services produced are all excluded by definition — "perfect" competition means indeed the absence of all competitive activities.

			Especially remarkable in this connection is the explicit and complete exclusion from the theory of perfect competition of all personal relationships existing between the parties. In actual life the fact that our inadequate knowledge of the available commodities or services is made up for by our experience with the persons or firms supplying them — that competition is in a large measure competition for reputation or good will — is one of the most important facts which enables us to solve our daily problems.

			No products of two producers are ever exactly alike, even if it were only because, as they leave his plant, they must be at different places. These differences are part of the facts which create our economic problem, and it is little help to answer it on the assumption that they are absent.

			That in conditions of real life the position even of any two producers is hardly ever the same is due to facts which the theory of perfect competition eliminates by its concentration on a long-term equilibrium which in an ever-changing world can never be reached. At any given moment the equipment of a particular firm is always largely determined by historical accident, and the problem is that it should make the best use of the given equipment (including the acquired capacities of the members of its staff) and not what it should do if it were given unlimited time to adjust itself to constant conditions.

			Competition is the more important the more complex or "imperfect" are the objective conditions in which it has to operate. Indeed, far from competition being beneficial only when it is "perfect," Hayek argue that the need for competition is nowhere greater than in fields in which the nature of the commodities or services makes it impossible that it ever should create a perfect market in the theoretical sense.

			The economic problem is a problem of making the best use of what resources we have, and not one of what we should do if the situation were different from what it actually is. There is no sense in talking of a use of resources "as if" a perfect market existed, if this means that the resources would have to be different from what they are, or in discussing what somebody with perfect knowledge would do if our task must be to make the best use of the knowledge the existing people have.<ref name="Hayek_Competition">Friedrich A.
