“Mathematical programming assisted by electronic computers becomes the fundamental instrument of long-term economic planning, as well as of solving dynamic economic problems of a more limited scope. Here, the electronic computer does not replace the market. It fulfils a function which the market never was able to perform.”

“Human needs, although originally derived from biological necessity, are thus a result of the existence of society and are conditioned by the stage of development which society has reached.”

“Capitalism operates only on the basis of private costs, only private costs are rewarded and repaid, and not social costs. And even in a competitive capitalism where competition forces producers to sell at cost price takes into account only private costs and not social costs.”

“Our conclusion about the objectivity of economic science may seem startling. Economists are rather notorious for being unable to reach agreement and for being divided into opposing "schools of thought," "orthodox" and "unorthodox," "bourgeois" and "socialist," and many others. The existence of profound disagr ment among economists, however, does not refute our thesis about the objectivity of economics as a science.”

“An economic system based on private enterprise and private property of the means of production can work only as long as the security of private property and of income derived from property and from enterprise is maintained. The very existence of a government bent on introducing socialism is a constant threat to this security. Therefore, the capitalist economy cannot function under a socialist government unless the government is socialist in name only.”

“It seems to us, indeed, that the real danger of socialism is that of a bureaucratization of economic life, and not the impossibility of coping with the problem of allocation of resources. Unfortunately, we do not see how the same, or even greater, danger can be averted under monopolistic capitalism. Officials subject to democratic control seem preferable to private corporation executives who practically are responsible to nobody.”

“The actual capitalist system is much better described by the analysis of Mrs. Robinson and of Professor Chamberlin than by that of Walras and of Marshall. But the work of the latter two will be more useful in solving the problems of a socialist system.”

“The capitalist system is far removed from the model of a competitive economy as elaborated by economic theory. And even if it conformed to it, it would be, as we have seen, far from maximizing social welfare. Only a socialist economy can fully satisfy the claim made by many economists with regard to the achievements of free competition.”

“The fundamental propositions of the theory of interest being obtained from a theory of production into which time does not enter as a variable, it follows that interest is not connected with time in any different way from the way in which the general theory of production is connected with time.”

“If people want to anticipate the development of Capitalism over a long period a knowledge of Marx is a much more effective starting point than a knowledge of Wieser, Boehm-Bawerk, Pareto or even Marshall (though the last-named is in this respect much superior). But Marxian economics would be a poor basis for running a central bank or anticipating the effects of a change in the rate of discount.”
