In perfect competition, a firm maximizes its profit by producing where:

Price is maximized

In the short run, a firm in perfect competition decides its production level based on:

In perfect competition, the price for all firms is:

Determined by the highest bidder
Constant and equal to the minimum of the demand curve

Total cost divided by total revenue

A firm in perfect competition will shut down in the short run if:

Total cost is less than total revenue
Total revenue is less than total cost
Total revenue is greater than total cost
Total cost is greater than total revenue

In perfect competition, firms are price-takers, meaning they:

Determine the market price based on demand
Set the market price
