Question

How is a seller under perfect competition a price-taker? What is the relevance of the characteristic that ‘there are large number of sellers’ in this context?

Answer 1

A seller under perfect competition is a price-taker because there are a large number of sellers, each producing a very small portion of the total market output. No single seller can influence the market price by changing their individual output. The market price is determined entirely by the overall demand and supply in the market. If a firm tries to charge a higher price, buyers will simply purchase from other sellers, and if it lowers the price, it will not gain much advantage due to the uniform market price.

The relevance of the characteristic “large number of sellers” is that it ensures no individual seller has market power to influence the price. Since each seller’s contribution to total supply is insignificant, a change in one firm’s output does not affect the overall market supply or price. This condition makes all sellers price-takers rather than price-makers in perfect competition.
