Perfect Competition

Under perfect competition a large number of firms compete against each other. Therefore, the degree of competition number perfect competition is close to one. Of the different kinds of market structures, the maximum competition happens in perfect competition. Monopoly has the least competition . The major characteristics of a perfect competition market are as follows :

a) There are a large number of buyers

b) There are a large number of sellers

c) The product is homogeneous

d) There are no entry and exit barriers


The more nearly perfect a market is, the stronger is the tendency for the same price to be paid for the same thing at the same time in all parts of the market.


A market is said to be perfect when all the potential sellers and buyers are promptly aware of the price at which transactions take place and all of the offers made by other sellers and buyers, and when any buyer can purchase from any seller, and vice versa.


Thus Perfect Competition is a market situation in which large number of buyers and sellers are gathered to deal in the similar product, having full knowledge of the market, equal price all over the market, and firms are free to enter into and to leave market.

Features/Characteristics of Perfect Competition

  1. A large number of sellers and buyers

Under perfect competition , the number of sellers and buyers is very large. The number of sellers and buyers is so large that the share of each seller in total supply and the share of each buyer in total demand is so small that no single seller can affect the market price by changing his supply, nor can a single buyer influence the market price by changing his demand.

  1. Homogeneous Product

 The products sold by perfectly competitive firms are so identical, that buyers are not able to distinguish the product of one firm from that of another firm. The product of each firm is regarded as a perfect substitute for the product of other firms. Nor do the firms distinguish between the buyers. For example unbranded spices, it would be very difficult for any consumer to differentiate between spices sold across the market. This is what we refer to as product homogeneity. This makes the buyers totally indifferent towards various sellers with respect to purchase of the product, because products of all the firms are perfect substitutes of each other.

  1. Freedom of entry and exit

All the firms are free to join or leave industry. There is no restriction on their entry and exit. Hence if the industry is making profits, new firms will enter into the market. Contrarily, if the industry is suffering loss, many firms will leave the market.

  1. Perfect Knowledge of Market Conditions

There is perfect dissemination of the information about the market conditions. Both buyers and sellers are fully aware of the nature of the product, its availability or saleability and of the price prevailing in the market.

  1. Perfect mobility of factors of production

For a market to be perfectly competitive, there should be perfect mobility of resources. This means that the factors of production must be in  a position to move freely into or out of an industry and from one firm to another.

  1. Independence of Decision Making

All the buyers and sellers are fully independent. None of them is committed to any one. Hence the buyers are free to purchase the commodity of their need from any seller and sellers are free to sell their commodity to any buyer or buyers. The price of a commodity at a particular time tends to be equal all over the market which all the firms have to follow.

  1. Perfectly Elastic Demand Curve

The demand curve of a perfectly competitive firm is perfectly elastic. If a particular firm decides to charge a price higher than the existing market price, its demand will be reduced to zero. This is because buyers have perfect knowledge about the product and the prevailing market price and they are indifferent about a particular firm, if one firm increases the price, buyers would promptly move away from this firm and shift over to its rival firms. On other hand, if a firm tries to gain advantage of increased demand by lowering the price, its demand would increase to infinity. Either of these lead to a perfectly elastic demand curve.

  1. No government intervention

In a perfectly competitive market, there is no government intervention with the working of the market system. There is no licencing system regulating the entry of firms to the industry, no regulation of market prices, i.e. fixation of lower or upper limits of prices, no control over the supply of inputs, no fixation of quota on production, and no rationing of consumer demand, etc.
