3. Firms and Consumers Have Perfect Information:

It implies that each firm is aware of the market prices and cost of manufacturing different products as well as the business opportunities available in each industry. The consumers also have perfect information regarding price charged by different firms for the same product.

4. Products are Homogenous:

In a perfectly competitive market, the products sold by different firms are so identical that one firm’s product cannot be differentiated from the products produced by the other firms. As a result, the consumers do not have any preference for products made by a particular firm.

Homogeneity of products not only refers to identical physical attributes of the products but also implies the same behaviour of the sellers, selling location etc.

5. Free entry and free exit:

Perfectly competitive market does not have any entry or exit barrier. The underlying meaning of this assumption is that the existing firms cannot stop the new firms to enter into the industry. Similarly, if any firm incurs losses, they may also close down the business and leave that industry without any hassle. An extension of this assumption is perfect mobility of the factors of production (raw materials, labour etc.).

If a firm observes that there exists a profitable business opportunity at a particular time and location, it will be able to mobilise all the relevant factors of production instantaneously for exploiting that opportunity.

Similarly, if the firm finds that the current business cannot offer the required rate of profit, the firm will be able to discharge its factors of production without any difficulty and delay.
