The
supply
of
a
thing
,
in
the
phrase
?
supply
and
demand
,
"
is
the
amount
that
will
be
offered
for
sale
at
each
of
a
series
of
prices
;
the
demand
is
the
amount
that
will
be
bought
at
each
of
a
series
of
prices
.
The
principle
that
value
depends
on
supply
and
demand
means
that
in
the
case
of
____________________
every
commodity
,
more
will
be
bought
if
the
price
is
lowered
,
less
will
be
bought
if
the
price
is
____________________
.
Therefore
sellers
,
if
they
wish
to
____________________
buyers
to
____________________
more
of
a
commodity
than
they
are
already
doing
,
must
____________________
its
price
;
if
they
raise
its
price
,
they
will
sell
less
.
If
there
is
a
general
falling
off
if
in
demand
?
due
,
say
,
to
trade
depression
?
sellers
will
either
have
to
reduce
prices
or
put
____________________
on
the
____________________
;
they
will
not
be
able
to
sell
the
same
____________________
at
the
same
price
.
Similarly
with
supply
.
At
a
certain
price
a
certain
amount
will
be
offered
for
sale
,
at
a
higher
price
more
will
be
offered
,
at
a
lower
price
less
.
If
consumers
want
more
,
they
must
offer
a
higher
price
;
if
they
____________________
less
,
they
will
probably
be
able
to
force
prices
down
.
That
is
the
first
result
of
a
change
in
demand
or
