are the only reservicing business in South Korea. Therefore, you have a local monopoly.
Your experience running the company for many years has taught you that market
demand for your service can be described by the demand function:
p = 20 - Q.
The cost function is c =q². Therefore, marginal cost equals 2q. Quantity refersto square
metre of road resurfacing. Note the Q denotes aggregate market demand and q denotes
your production. Of course, if you are the only supplier than q = Q.
a) Compute profit maximising price and output. Compute profits.
b) The monopoly profit that you have been earning has attracted attention
from another firm that will set up operations in South Koreaand
compete for market share. You are concerned with losing market share

iii.
How much profit will each firm earn?
iv. What will be industry profits?
c) When you make the offer detailed in part b), the potential entrant
observes that aggregate industry profits are different than when the
