Question 1
Assume that capital and labor are complementary inputs. If the firm increases the amount of capital it employs, this would
◦ cause the firm to move down along the
MP schedule for labor.
◦ cause the firm to move up along its
MP schedule for labor.
◦ shift the firm's
MP schedule for labor to the left.
◦ shift the firm's
MP schedule for labor to the right.
Question 2
The cost-minimizing equilibrium condition can be written as
◦
MPL =
MPK.
◦
PL =
PK.
◦ (
MPL)(
PL) = (
MPK)(
PK).
◦
MPL/
PL =
MPK/
PK.
