Describe a perfectly competitive market?

• A. Many producers supply identical product; prices set by supply and demand
• B. A single producer sets prices
• C. Prices set by government
• D. A few producers control market

Answer: (A)

In a perfectly competitive market, many producers supply an identical product, and no single seller can influence the price. Because each firm is tiny relative to the whole market, it takes the going market price as given (price takers) and chooses its output to maximize profit. The price itself is set by the overall forces of supply and demand, so the market reaches a single equilibrium price and quantity. Characteristics like a homogeneous product, easy entry and exit, and perfect information help ensure that no firm can earn sustained profits by charging more or less than the market price.

The other scenarios wouldn’t fit: a single producer setting prices describes a monopoly, government-set prices describe price controls, and a few producers controlling the market describe an oligopoly or imperfect competition.
