FLUCTUATIONS

§ j. Short Period and Long Period Fluctuations.
Now, if in the skilled trades here represented we are
justified in counting the minor “ leakages ” and special
displacement due to introduction of new machinery, etc.,
us a fairly constant quantity, taking one year with another,
we cannot fail to recognise that some greater forces
are at work which account for the large bulk of the
unemployment here displayed. In January, 1900, the
necessary minor “leakages” and specific displacements
were going on, and yet these only caused 2.7 unemployment.
If, then, we are called upon to explain why in
January, 1903, 10 per cent, are “unemployed,” we must
seek another cause or causes. A further comparison of
one year as a whole with another will disclose the fact
that the force to which we must attribute the mass of
unemployment is one which operates over wider periods
than a year. We are driven irresistibly to the conclusion
that the great tidal movements of trade, and not the
minor detailed movements of special trades, are the rootcauses
of the evil we are investigating. No accumulation
of minor short-period causes will explain why, on the
average, throughout 1899 the rate of “ unemployment ” was
only 2.4, while in 1893 it was 7.5, and in 1894 6.9.
So far as these statistics of skilled trades can be taken
as an index of general trade movements, we must conclude
that the great trade depressions are the vital factor
with which we have to deal, and that no palliatives or
cures will be of much service unless they serve to mitigate
the force of these vast world-movements in trade.
