Effective Demand Quotes

“In the last chapter of the /General Theory, /quoted above,^35 he [Keynes] falls into the fallacy of supposing that there is some kind of /neutral /policy that a Government can pursue, to maintain effective demand in general, without having any influence upon any particular demand for anything. The Government has to undertake “the task of adjusting to one another the propensity to consume and the inducement to invest” but everything else is best left to “the free play of economic forces.”^36

This is a metaphysical conception as unseizable as /abstract labour /or /total utility. /What is a policy which /merely /adjusts the demand for investable resources to the supply?

To increase effective demand when it threatens to flag, various means can be used: to reduce taxation or to shift the burden from those most likely to increase their consumption to those most likely to reduce their savings; to foster competition so as to reduce profit margins; to increase subsidies or outlays on social services — all means which tend to reduce inequalities in consumption. Or Government expenditure on investment can be increased, directly or through nationalized industries, or reductions in taxation and credit policy can be used to encourage private investment. Contrariwise, when effective demand seems excessive, taxes to discourage consumption, credit restriction and reduced Government expenditure can be brought into play. And all this has to be worked out so as to preserve the balance of trade at some level or other, as well as to preserve employment. What is a /neutral /policy? What mixture of these means is it that leaves private enterprise unaffected in content and acts only on the quantity?

“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]”
