Zorluk: OrtaPerfect Competition: Price and Output Determination in Short and Long Run

If the market price falls below a perfectly competitive firm's short-run average total cost but remains above its average variable cost, the firm minimizes its losses by shutting down operations immediately.

Cevap: Cevap

Cevap

False. A perfectly competitive firm will continue operating in the short run to minimize losses as long as price covers average variable cost (P>AVCP > AVC), even if price is below average total cost (P<ATCP < ATC).
The statement is false because a firm minimizes losses by continuing production whenever market price covers average variable cost (P>AVCP > AVC). Because total fixed costs must be paid even at zero output, any excess revenue above variable costs reduces the overall loss compared to producing nothing.

Adım Adım Çözüm

1
Analyze the firm's price and cost relationship in the short run.
The firm operates where AVC<P<ATCAVC < P < ATC. Total revenue exceeds total variable cost (TR>TVCTR > TVC), but does not cover total cost (TR<TCTR < TC).
This indicates that the firm is suffering an economic loss.
2
Compare total losses under operation versus total losses under shutdown.
If the firm shuts down, output is zero (Q=0Q = 0) and its loss equals total fixed cost (TFCTFC). If it operates, revenue covers all variable costs and part of fixed costs, making losses less than TFCTFC.
Fixed costs cannot be eliminated in the short run.
3
Formulate the short-run production rule.
The firm continues producing output where MR=MCMR = MC to minimize loss, shutting down only if P<AVCP < AVC.
The short-run shutdown threshold is determined by the minimum point of the average variable cost curve.
