ELASTICITY OF SUPPLY AS A DETERMINANT OF DISTRIBUTION 111
would otherwise be the case, and consequently would cause the
supply of this other factor to be produced more abundantly. This
in turn would raise the marginal productivity of the larger’
factor more than under the condition of equal sharing in the
product. Where, however, the smaller factor successfully takes
the aggressive, the unit loss to the larger factor is of a smaller
relative magnitude than its own gain, and consequently the
quantity of the other and larger factor will expand less than
would be the case where equal sharing prevailed, and a one per-
cent increase to one factor was accompanied by a one percent
loss to the other. Hence the ultimate marginal productivity of
the smaller factor will be less than it otherwise would be and it
would profit less from an increase in the effectiveness of its
bargaining power.
The matter may indeed be summed up by saying that it is to
the advantage of the factor which improves its bargaining power
to expand as little as possible in quantity, and indeed to decrease
as rapidly as possible, while the less the other factor decreases
and indeed the more it increases, the greater will be the perma-
nent gain secured by the factor which has advanced its bargain-
ing power. But such movements in the relative quantities of the
factors are not only caused by (a) the relative elasticities of the
supply of the factors as analyzed in the sections five, six and
seven, but also (b) the relative proportions of the total product
obtained originally by the two factors.
(1) When both factors have positively inclined supply curves,
the smaller the share enjoyed by the factor which improves its
position, the more it can gain, and the larger its share the less
it can gain. (2) When both factors have negative supply curves,
the larger the share of the factor which improves its position
the more it can gain, and the smaller its share, the smaller will be
its ultimate increased return per unit. (3) When one factor is
negative and the other is positive, both will gain more if, when
they improve their bargaining strength, the positive factor has
the larger share while both would lose more than they would
otherwise do if the negative factor were to have the larger share.
With regard to the quantity of a factor supplied the combined
