Answer:
a)
At Price 56, the equilibrium quantity is Q=8, because beyondQ=8, the Marginal Cost MC > Price of 56
Profit = TR – TC
=PQ – ATC*Q
=56*8 – 48.13*8
=62.96
The firm will produce in the short-run
The profit-maximizing output = Q =8
Economic profit = 62.96
At Price 40, the equilibrium quantity is Q=6, because beyondQ=6, the Marginal Cost MC > Price of 40
Profit = TR – TC
=PQ – ATC*Q
=40*6 – 47.5*6
=-45
The average variable cost at Q =6 is 37.5
Since the Price of 40 > average variable cost of 37.5, thefirm will produce in the short-run
The profit-maximizing output = Q =6
Economic loss = -45
At Price 32, the equilibrium quantity is Q=0, because Price of32 is lower than the average variable cost at each level ofoutput
Profit = TR – TC
=PQ – TFC
=0- 60
=-60
Since the Price of 32 <average variable cost atall levels of output, the firm will not produce in theshort-run
The profit-maximizing output = Q =0
Economic loss= TFC = 60
P = 56 | P = 40 | P = 32 | |
Will this firm produce in the short run (yes or no)? | Yes | Yes | No |
What is the profit-maximizing output? | 8 | 6 | 0 |
What economic profit or loss? | Economic Profit = 62.96 | Economic loss = -45 | Economic loss = 60 |
b.
The long-run equilibrium price is the minimum of the averagetotal cost, that is 47.14
c.
The shutdown price is the minimum of average variable cost, thatis 37
