Long-Run Output Decision:
In the
long run
,
all
inputs (like labor, capital) are
variable.
The firm's main objective is to
maximize profit
or
minimize loss.
The
decision
rule in the long run: choose the
output
where
Marginal Revenue
(MR) =
Long-Run Marginal Cost
(LMC).
Long-Run Average Cost (LAC):
LAC represents the
average cost
per
unit
of
output
when
all inputs
can be
adjusted.
If the price is
greater
than
LAC
(
firm
covers
all costs
), the firm makes
profits.
If the price is
less
than
LAC
, the firm incurs
losses.
Marginal Revenue (MR) Curve:
The MR curve represents the
additional revenue
gained by
selling
one more
unit
of
output.
Firms
maximize profit
by producing where MR =
LMC.
LAC
Curve (
Long-Run Average Cost
): Shows the
lowest average cost
at which a firm can produce
different levels
of
output
in the
long run.
LMC
Curve (
Long-Run Marginal Cost
): Reflects the
change
in
total cost
as the firm changes its
output level.
MR Curve (Marginal Revenue): Represents the
additional revenue
from selling an
extra unit
of
output.
Long-Run Output Decision:
If price is
greater
than or
equal
to LAC1: The firm
produces Q1
and stays in
business
since it covers its
costs.
If price is
less
than LAC1: The firm should
shut down
because it cannot cover its
long-run average cost.
equilibrium point where
LMC
=
MR
and represents the
optimal output
level
The firm should produce where
LMC
=
MR
and where the firm can
cover
its
LAC.
If the price
falls
below
LAC1
, the firm should
exit
the market.
The long-run decision focuses on
minimizing
costs while ensuring that all
variable
inputs (
labor
and
capital
) are fully
adjustable.

If price is greater than or equal to LAC1: The firm produces Q1 and stays in business since it covers its costs.
If price is less than LAC1: The firm should shut down because it cannot cover its long-run average cost.
The firm should produce where LMC = MR and where the firm can cover its LAC.
If the price falls below LAC1, the firm should exit the market.
