118 THE PROBLEM OF THE UNEMPLOYED
§ 5. Does a Fall of Prices Come from Increased
Supply or Restricted Demand?
Since a continuous fall of prices means nothing else
than an actual excess of supply over quantity demanded
at former prices, it may be explained either by the operation
of forces which feed Supply without stimulating
Demand to a corresponding extent, or by the operation
of forces which act primarily as a restriction of demand.
Since bimetallists repudiate the explanation that the fall
of prices since 1873 is due to a cheapening of “cost” of
production which has enlarged supply, they are driven to
the alternative admission that the result of an insufficient
supply of money is to restrict demand for goods. This
admission is seldom made in so many words because
currency men often seem to lose sight of the principle
that price-change always means in the first instance a
change in the quantitative relation of supply and quantity
demanded at a former price. But the bimetallist position
clearly rests upon the assumption that an insufficient
supply of money disables purchasers from buying as much
as they would otherwise have done. The two explanations
of falling prices, an enlargement of supply and a restriction of
demand, form, it is true, no logical antinomy ; both forces may
be operative in different degrees ; but for testing the truth or
falsehood of the financial explanation of depressed trade,
we may treat them as alternatives. Our position is that
the forces which depress prices have in fact operated by
enabling larger quantities of goods to be added to supply
at less labour-cost, and that in order to effect sales the
owners of these goods have been constantly obliged to
lower prices.
