As is by now well known, attempts to form social judgments by aggregating individual expressed preferences always lead to the possibility of paradox. - Kenneth Arrow

The idealist doctrine then may be summed up by saying that each individual has two orderings, one which governs him in his everyday actions, and one which would be relevant under some ideal conditions and which is in some sense truer than the first ordering. It is the latter which is considered relevant to social choice, and it is assumed that there is complete unanimity with regard to the truer individual ordering.

From a theoretical viewpoint, one might say that the market is in a strange sort of equilibrium; there is some shadowy sort of price at which supply and demand are equated at zero. But this price is not performing much of a signaling function.

The Soviet Union and its satellite Socialist countries in Eastern Europe have typically avoided unemployment and business cycles, except as they are induced through their trade with the Western World. But on the other hand they are clearly inefficient and wasteful, at least relative to the West. As repeated statements by the socialist economists themselves make clear, the excessive concentration of economic decision-making is a prime cause of the inefficiency. There are recurring demands for "liberalization," even by the highest authorities (Yuri Andropov, the effective head of the Soviet Union, being the latest example), but they are responded to only mildly or not at all. Clearly, a really major step toward decentralization of economic power, to the plant managers or the workers themselves, is perceived as a threat to the system.
