Quote by Joan Robinson

“After the war, when the problem of deficient effective demand seemed to have faded into the background, a fresh question came to the fore — long-run development. The change arose partly from the internal evolution of economics as an academic subject. The solution of one problem opens up the next; once Keynes’ short-period theory had been established, in which investment plays the key role, it was evidently necessary to discuss the consequences of the accumulation of capital that investment brings about. [p. 92]”

“The analysis of the /General Theory /shows that inflation is a real, not a monetary, phenomenon. It operates in two stages (once more giving a crudely simple account of an intricate process). An increase in effective demand meeting an inelastic supply of goods raises prices. When food is supplied by a peasant agriculture a rise of the prices of foodstuffs is a direct increase of money income to the sellers and increases their expenditure. The higher cost of living sets up a pressure to raise wage rates. So money incomes rise all round, prices are bid up all the higher and a vicious spiral sets in. The first stage — a rise of effective demand — can very easily be prevented by not having any development. But if there is to be development there must be a stage when investment increases relatively to consumption. There must be an increase in effective demand and a tendency towards inflation. The problem is how to keep it within bounds. Some schemes of investment that seem to be clearly indispensable to improvements in the long run, such as electrical installations, take a long time to yield any fruit and meanwhile the workers engaged on these have to be supplied. The secret of non-inflationary development is to allocate the right amount of quick-yielding, capital-saving investment to the consumption-good sector (especially agriculture) to generate a sufficient surplus to support the necessary large schemes. It is in this kind of analysis, rather than in the mystifications of “deficit finance,” that the clue to inflation is to be found. [pp. 110-11]”

“The /utility /economists, according to Wicksell, were committed to a “thoroughly revolutionary programme” precisely on this question of distribution of income.^9 Marshall, and to some extent Pigou, got out of the fix that their theory had landed them in by emphasizing the danger to total physical national income that would be associated with an attempt to increase its /utility /by making its distribution more equal. This argument has been spoiled by the Keynesian revolution. If, as Keynes expected, saving is more than sufficient for a satisfactory rate of private investment, to use it for social purpose is not only harmless but actually beneficial to National Income, while if more total saving is needed than would be forthcoming under /laisser faire /it can easily be supplemented by budget surpluses. Edgworth, as we saw above,^10 and many after him, took refuge in the argument that we do not really know that greater equality would promote greater happiness, because individuals differ in their capacity for happiness, so that, until we have a thoroughly scientific hedonimeter, “the principle ‘every man, and every woman, to count for one,’ should be very cautiously applied.”^11 Many years ago, this point of view was expressed by Professor Harberler: “How do I know that it hurts you more to have your leg cut off than it hurts me to be pricked by a pin?” It seemed at the time that it would have been more telling if he had put it the other way round. Such arguments are getting rather dangerous nowadays, for though we shall presumably never have a hedonimeter whose findings would be unambiguous, the scientific measurement of pain is fairly well developed, and it would be very surprising if a national survey of the distribution of susceptibility to pain turned out to have just the same skew as the distribution of income. If the question is once put: Would a greater contribution to human welfare be made by an investment in capacity to produce knick-knacks that have to be advertised in order to be sold or an investment in improving the health service, it seems to me that the answer would be only too obvious; the best reply that /laisser-faire /ideology can offer is not to ask the question.

“There was frequently a moral lesson lurking just below the surface in Hayek’s accounts, usually having to do with Keynes’s overweening self- confidence and the dangers of hubris. His retelling of their final conversation is illustrative. Hayek had asked Keynes whether he was at all concerned about the uses to which his disciples were putting his theories, and in particular, whether a theory that had made sense in “the age of plenty” of the 1930s might not stimulate inflation as the economy neared full employment. Keynes assured Hayek that were his theories ever to become harmful, he could turn public opinion against them like that, and snapped his fingers. Unfortunately, as Hayek concluded, “six weeks later he was dead”.”

“Those concessions might also explain why Keynes responded to the book as he did, a response that might surprise later generations. Keynes read it on the boat on the way to Bretton Woods, and on arriving in Atlantic City sent a letter saying that it was a “grand book” and that “morally and philosophically I find myself in agreement with virtually the whole of it; and not only in agreement with it, but in a deeply moved agreement” (Keynes to Hayek, June 28, 1944, quoted in Keynes 1980b, 385). Keynes went on to say that they would probably disagree on the question of where to draw the line regarding more or less intervention. Keynes thought that almost certainly more planning was necessary, which could be carried out safely if the lead- ers were “rightly orientated in their own minds and hearts to the moral is- sue” (Keynes 1980b, 387). So there were obvious differences between them. But the general sentiment expressed underlines once again the fact that in the context of their times and especially with respect to central planning and the men of science who advocated such a path for Britain, Keynes and Hayek were on the same side.”
