Assume a competitive firm faces a market price of
$60, a cost curve of: C = 0.003q3+ 50q + 1000,
The firm's profit-maximizing output level is ___ units (enter your response rounded to two decimal places), and the per unit profit at this output level is $____ (enter your response rounded to two decimal places—include the minus sign if necessary).
This firm will▼ _______ (shut down or produce) in the short-run. The firm will realize▼________(economic profit or economic loss) , and ▼ ______ (must or may or may not) have a business profit.
In the long-run, if circumstances do not change, this firm will ▼_______ (shut down or produce).
Profit maximizing level where P = MC ( because this is a competitive firm)
MC = d(C)/dQ
MC = d( 0.003q3+ 50q + 1000) / dQ
MC = 0.009q2 +50
Put P = MC
60 = 0.009q2 + 50
10 = 0.009q2
10/0.009 = q2
q = 33.33
Per unit profit = (P-ATC)
ATC = C/Q = 0.003q2 + 50 + 1000/q
Put q = 33.33
ATC = 0.003(33.33)2 + 50 + 1000/33.33
ATC = 83.35
Per unit profit = P - ATC = 60- 83.35 = -23.35
The firm's profit-maximizing output level is 33.33 units (enter your response rounded to two decimal places), and the per unit profit at this output level is - $23.35
----
The firm will shut down in the short run if AVC is more than price
AVC = VC/Q [ VC = 0.003q3 + 50q]
AVC = 0.003q2 + 50
AVC = 0.003(33.33)2 + 50 = 53.33
As AVC is less than $60 so the firm will produce in the short run.
This firm will produce in the short-run. The firm will realize economic loss , and may or may not have a business profit.
In the long-run, if circumstances do not change, this firm will shut down.
