Ch.12 Perfect Competition and the Supply Curve Flashcards
conditions for perfect competition
- many producers, non has a large market share
- standardized product (commodity)
- free entry and exit (usually)
optimal output rule
max profit when price is set where MR = MC
to make a profit…
price > average total cost ATC
short run decision
P > min average variable cost, produce
P = min AVC, produce
P
Price must exceed ____ to make a profit
minimum ATC, the break even price
in the long run equilibrium with perfect competition
- MC is same for all firms
- each firm has 0 economic profit
- efficient
marginal revenue
revenue earned from selling one more of a good
shut- down price
minimum average variable cost AVC
in short run, firms ignore…
fixed costs
break even price
minimum average total cost ATC
minimum cost output
in the long run equilibrium with perfect competition
- MC is same for all firms
- each firm has 0 economic profit
- efficient, profit maximized
short-run individual supply curve is equal to
MC curve at/above the shut-down price
