Characteristic
- Many small firms Identical products (perfect Substitutes)
- Low Barriers to Entry - easy for firms to enter and exit the industry
Seller has no need to advertise - Firms are "Price Takers" - each firm has no control over price


Perfect Competition in the Long-Run
Firms will enter if there is Profit
Firms will leave if there is loss
So, all firms break even, they make NO Economic Profit (No Economic Profit = Normal Profit) In Long-Run Equilibrium a perfectly competitive firm is extremely efficient.
Price = Marginal Cost (MC) = Minimum Average Total Cost (ATC)
