workers a wage equal to $160 per day. What is the value of the marginal product of
labor for the fourth worker?

3) Ty lives in an apartment building and gets a benefit from playing his stereo. Olivia,
who lives next door to Ty and often loses sleep due to the loud music coming from Ty€s
stereo, bears a cost from the noise. Olivia is threatening to call the police to force Ty to
turn down his stereo. Under which of the following conditions would Ty be able to offer
Olivia some amount of money to keep her from calling the police and to allow him to
continue to play his stereo loudly?
a.The cost of the noise to Olivia must exceed the benefit of the music to Ty.
b.The benefit of the music to Ty must exceed the cost of the noise to Olivia.
c.The Coase Theorem guarantees that Olivia and Ty will always be able to come to an
agreement that keeps Olivia from calling the police regardless of the individual benefits
and costs.
d.The cost of the noise to Olivia must exceed the benefit of the music to Ty by an
amount greater than the transaction costs associated with the agreement.
