The world economy is winessing excess capacity reaching levels not seen since
the 1930s. In the US it is now about 68 per cent. Last March Justin Lin, the
World Bank's chief economist, gave a speech in which he warned about the dangers
of excess capacity. In July he followed this up with another speech in which
he stated that "unless we deal with excess capacity, it will wreak havoc on
all countries". Excess capacity is evidently becoming an idee fixe.
And he is not the only one to sufferomg from this affliction.
Like the great majority of economists Lin was spoon-fed Keynesianism as a
student. Now in fairness to Lin he did say that economists must move beyond
Keynes to solve the present problem. What this really means is that Lin has
yet to discover what the real problem is. Now economics is qualitative and
not quantitative. This means that because economics deals with human action
there can be no mathematical relationships. What economists should be applying
to economic problems are not formulas or correlations but long chains of complex
reasoning, sometimes referred to as "verbal logic".
Unfortunately this approach is sneered at by the vast majority of today's
economists who treat that method as hopelessly old fashioned. This is why those
like Lin who are steeped in the mathematical approach find -- unlike the Austrians
-- the current situation incomprehensible. Left floundering for a solution
Lin is reduced to calling out for an explanation that goes beyond Keynes. However,
sound economics long preceded Keynes and easily provides a ready explanation
for what confounds the perplexed Mr Lin.
Lin is buying into the fallacy that excess capacity risks triggering a "deflationary
spiral" that will result in "mass lay-offs and drastic falls in investment
as firms retrench". Deflation properly understood is a contraction in the quantity
of money, not a fall in prices. From about the 1874 to the mid-1890s prices
fell steadily in Great Britain. Because of this phenomenon the period is sometimes
called the "Great Deflation" even though the money supply continued to grow
along with wages and employment.
In other words, the received wisdom that this was a deflationary period is
a myth whose origins spring from the lamentable fact that the vast majority
of economists can no longer distinguish between a monetary induced fall in
prices and a productivity induced fall. The first phenomenon is a real deflation.
The second phenomenon is the result of falling costs brought about by greater
investment in capital goods embodying improved technology. What makes the present
situation truly deplorable is that this fact was well known to contemporary
economists. Alfred Marshall pointed out that
...in the same way a manufacturer, though he has to pay for raw material
and wages would not check his production on account of a fall in prices,
if the fall affected all things equally, and were not likely to go further.
If the price which he got for his goods had fallen by a quarter, and the
prices which he had to pay for labour and raw material had also fallen by
a quarter, the trade would be as profitable to him as before the fall. Three
sovereigns would now do the work of four, he would use fewer counters in
measuring off his receipts against his outgoings; but his receipts would
stand in the same relation to his outgoings as before. His net profits would
be the same per centage of his total business. The counters by which they
are reckoned would be less by one quarter, but they would purchase as much
of the necessaries,, comforts and luxuries of life as they did before. (Economics
of Industry C. J. Clay, M. A. & Son, 2nd edition, 1881, p. 156).
In other words, falling prices are not only not a symptom of deflation when
they are productivity-induced but they are to be welcomed. Therefore what matters
to the producer is not the absolute level of prices but price margins. Robertson
endorsed this view when he wrote:
Thus ... a policy aiming at ultimate stability of the general price-level
seems to be neither the "most natural" nor the "most effective" policy for
the monetary authority to adopt. (D. H. Robertson, Banking Policy and
the Price Level, Augustus M. Kelley, 1989, p. 32, first published 1926).
On the other hand, nineteenth century economists were very much aware of the
existence of excess capacity. Unlike today's economists they did not confuse
cause with effect. They knew that the emergence of idle capacity and widespread
unemployment was a symptom of depression not a cause just as they knew that
deflation is the product of a monetary contraction. Although their view of
capital was far from being fully developed (John Rae's New Principles of
Political Economy, published in 1834, was a remarkable exception) they
understood that it involved the misallocation of resources and this is why
they called this state of affairs one of "disproportionality", meaning that
the saving-consumption ratio had been disturbed which in turn created a situation
where a great number of unsustainable investments (malinvestments) had been
made that would have to be liquidated at a later date. There was not the slightest
doubt in their minds that booms were an economic curse that must always have
a most unhappy ending. Thus Mill observed more than 170 years ago:
If alI are endeavouring to extend them [their operations], it is a certain
proof that some general delusion is afloat. The commonest cause of such delusion
is some general, or very extensive, rise of prices (whether caused by speculation
or by the currency) which persuades all dealers that they are growing rich.
And hence, an increase of production really takes place during the progress
of depreciation, as long as the existence of depreciation is not suspected....
But when the delusion vanishes and the truth is disclosed, those whose commodities
are relatively in excess must diminish their production or be ruined: and
if during the high prices they have built mills and erected machinery, they
will be likely to repent at leisure. (John Stuart Mill, Essays on Economics
and Society, University of Toronto Press 1967, London: Routledge & Kegan
Paul, p. 275).
The Austrians built on these insight and explained that "excess investments" were
created by forcing the rate of interest down below its market rate, the rate
that equates the supply of capital with demand for capital. This sent a false
signal to businessmen that there was more capital available than actually existed,
encouraging them to take on more time-consuming investments. Eventually the
party would have to come to an end as the shortage of capital made itself felt
and bottlenecks emerged.
Of course, if the current account was blowing out that might cause the central
bank to apply the monetary brakes before the shortage of capital became too
severe. Nevertheless, "excess capacity" would still emerge and for the same
reason. We can see that the idea that "excess capacity" is the result of demand
deficiency is a dangerous fallacy that results in accelerating inflation and
even more malinvestments as the central bank ramps up the money supply in an
attempt to cut "idle capacity".
There is only one way avoid mass layoffs and to prevent masses of capital
from being rendered idle and that is for central banks to adopt sound economics.
Unfortunately this will never happen while economists like Bernanke and Lin
insist on practising "macromancy".
