I cant work out the answers for the short answer questions as well. It seems so damn easy!

a) marginal cost pricing
b) to maximise revenue, the firm should produce where P=MC on the upward slope of the MC curve (obviously), however, at this point P<AVC so the firm produces nothing to minimise loss
c) Firms minimise cost i.e. produce as close to minimum ATC as possible, therefore q=5, P=7 as ATC = 7
d) not sure

monopolies are a source of inefficiency :p

they can eliminate it by price discrimination though


otherwise, they produce for profit maximisation i.e MR = MC

the question is so ambiguous...

a) is 7 cuz at p = 20, the firm is willin to produce up to 7 units (mc of 13 contrasting to 8th, which has mc of 21) and the firm can recoup it's variable cost (avc = 15.8<20)

b) is 0 as it firm will be willing to produce to 6th unit, provided that they recoup their variable cost (avc = 18 >10), they can't, so wise thing is not to produce...

c) well xiaoie didn't read the q properly, so i thought twas a monopolistic competition... but then again, it's perfect competition... the eqlbm q is at when LRATC = minimum... which is at q = 5... and for perfect competition, there are no super normal profit... so TC = TR... and TC = ATC x Q = 35... and TR = Q x P
so P = 7

d) is the ambiguous part... u don't really know if it is an increasing /decreasing /constant cost industry... in exam, i would have put all three scenarios down...

in this case, it is a constant cost industry, having long term supply curve of the industry as a horizontal line...

@ sarah: or the govtmt can put a price ceiling ^^
