Perfect competition
Perfect competition is a market model with many buyers and sellers, a homogeneous product, adequate information and free entry and exit. An individual firm is too small to influence the market price and is a price taker. The model provides a benchmark for analysing behaviour rather than a description every real market fully satisfies. Long-run normal economic profit does not mean there is no accounting profit or reward for the owner’s resources.
Worked example
A small supplier in an idealised homogeneous market can sell at the market price but loses buyers if it charges more for the identical product. It chooses output with regard to its costs rather than setting the market price.
Common mistake
Do not equate many competitors alone with perfect competition. Product differentiation, information limits and barriers can change the analysis.
