“The current emphasis on price policy, as against price, as a proper object of study represents recent economic reflection on the significance of expectations, uncertainties, market control, and the position of price as one among many selling terms. Policy implies some degree of control over the course of events and, at the same time, the use of judgment as to the probable consequences of alternative lines of action. In perfect markets, whether monopolistic or competitive, price is hardly a matter of judgment and where there is no judgment there is no policy. The area of price policy, then, embraces the deliberative action of buyers and sellers able to influence price; that is to say, it covers practically the whole field of industrial prices.”
