A perfectly competitive market is defined as a market in which no individual firm can influence the market price on its own. Features 1. Large number of buyers and sellers – The number is so large that no single buyer or seller can affect the market. It implies that individual output of every seller is the negligible fraction of total output, so no one of them is capable of influencing the market, so they have to accept the price prevailing in the market. 2. Homogenous product – Goods produced by different firms are homogenous so that all buyers are willing to pay the same price for the product of all producers of a good. 3. Freedom of entry and exit of firms – There are no obstacles in the way of new firms joining the industry and existing firms leaving the industry. This ensures that there are neither above normal profits nor losses by any firm in the long-run. 4. Perfect knowledge of market conditions – This means that all producers and consumers are fully informed about the market. So, no consumer is prepared to pay a price higher than what is being charged in other parts of the market. 5. Perfect mobility of factors of production – mobility of factors from one industry to another industry, which gives them more remuneration.

Under perfect competition market, a firm is only a price taker. If a firm tries to sell at a price higher than market price it will lose all its customers. Nor can it afford to change a price less than the prevailing market price. It will not be beneficial for it to do so. This is because; the production of a firm under perfect 2

competition constitutes a very small fraction of the total production of the industry. A firm can sell its entire production at the prevailing market price. Hence, its marginal revenue is equal to its average revenue. Meaning of Monopoly “Monopoly is that market situation in which a firm has the sole right over production or sales of the product and it has no competitor in the market and no close substitute for its product”. 1. A single seller – There is only one producer of a product. It

may be due to some natural conditions prevailing in the market, or may be due to some legal restriction due to patent, copyright, state monopoly etc. No close substitutes – A monopoly market has no such close substitutes and, therefore, practically does not face any competition. Restrictions on the entry of new firms – Other firms are prohibited to enter this type of market. There are strong barriers that prevent entry of new firms into the industry. Firm is a price maker – Monopoly firm has full control over the supply of its product. The firm has full control over the supply becausea) thee is no competition in the market b) there are barriers to the entry of new firms. Possibility of price discrimination – The act of selling the homogenous product at different prices to different buyers is known as ‘ price-discrimination’. This act is possible If the monopolist have full control over supply, and operates in different market with no possibilities of resale, and different elasticities in different market. No selling cost – As there is no competition, hence, there is no need to incur advertisement costs or selling cost.

Causes responsible for emergence of monopoly 1. Natural factors – There are certain commodities which are

available in specific geographical area and climate. When a firm owns all the deposits of some specific minerals, it has to face no direct competition. 2. Legal prohibitions – The law may prevent the entry of new rival firms into the industry. 3. Cost factors – The firm enjoys monopoly, if its business has attained large size and highest order of efficiency. 4. Heavy investment – If certain industry requires heavy investment, competitive firms cannot be formed easily. AR & MR curve under Monopoly Under monopoly the AR curve slopes downwards form left to right. It means that if a monopolist desires to sell more units of the output, he will have to reduce the price & vice-versa. Hence there is a negative relationship between the demand for the product of a monopolist and its price.

Meaning of Monopolistic competition market “is a market situation where there is a large number of buyers and sellers selling closely related goods but surely not homogenous”. Features 1. Large no of sellers and buyers – As there are large no. of sellers and buyers , so the individual firm or buyers is incompetent to affect the price of the industry. Every firm 4

has its own price and output policy and does not bother much for the reactions of rival firms. Product differentiation - The products of different firms are not homogeneous but are close substitutes. Products are differentiated from each other in terms of brand name, colour , shape, quality , and type of service etc. Due to product differentiation, firms enjoy partial control over price, and have a independent price policy. Free entry and exit – Firms are free to join and leave the industry at their own will. A new firm may enter the industry and produce close substitutes, without significantly affecting the market. Free entry and exit imply zero profit in long run. Selling cost – Expenditure on advertisement are made to persuade buyers to buy a particular brand of the product in preference to other brands. Imperfect knowledge of market conditions – Due to product differentiation, it become difficult to compare the price of different products. Sometimes, the products of different sellers are really the same, but consumers may come o know a particular brand name more than others.

AR & MR curve under monopolistic competition market The AR & MR curve under monopolistic competition market is more elastic. If a firm under monopolistic competition raises the price ; the proportionate fall in its demand will be more. It is so because in an monopolistic competitive market goods have their substitutes and buyers are equally attracted towards them. If one firm raises the price of its products, the buyers will shift their demand to the substitute product, whose price remains unchanged. Thus, if a firm raises price, demand for its product will fall substantially and conversely, if its lowers the price, demand for its product will rise considerably.

Returns to scale Meaning – “ returns to scale relates to the behavior of total output as all inputs are varied in same proportion and it is a long-run concept”. The output in long period may show three possibilities – a) Increasing returns to scale b) Constant returns to scale Diminishing returns to scale.

c)

Increasing returns to scale Increasing returns to scale occur when a given percentage increase in all factor input causes proportionately greater increase in output. Causes of increasing returns to scale Economics of scale refers to the situation in which increasing the scale of production reduces the unit cost of production or raises output per unit of the factor inputs. It can be of two types – internal economies of scale and external economics of scale. Internal economies of scale – are those economies which are firm – specific. These are available to that particular firm in the industry which seeks to increase its level of output by way of increasing its scale of production. a) Technical economies – when a firm increases its scale of production, it becomes possible for it to make use of modern machines and superior technique of production. b) Labour economies – it becomes possible for the firm to introduce complex division of labour which results in greater efficiency of lab our and hence fall in the cost of production. c) Managerial economies – The firm producing on large scale can afford o engage competent and efficient manages.

Causes of diminishing returns to scale Internal diseconomies – refers to those factors which raise the cost of production of a firm, if its scale of production is increased beyond a point. These includes – a) management and co-ordination of different departments become difficult. b) Technical difficulties in the cooperation would stat emerging. c) A firm may have to pay more for increased supply of factos inputs.

b) As an industry expand, there will be competition among it s member firms for the factors of oproduction. c) When an industry is developed at a particular lplace, cost of stransportation increases.
