Perfect competition is defined as a market situation where there are a large number of sellers of a homogeneous product. An individual firm supplies a very small portion of the total output and is not powerful enough to exert an influence on the market price. A single buyer, however large, is not in a position to influence the market price.

9.2 Output Determination in the Short Run

Perfect Competition which may be defined as an ideal market situation in which buyers and sellers are so numerous and informed that each can act as a price taker, able to buy or sell any desired quantity affecting the market price. According to A. K, Koutsoyianis ,"Perfect competition is a market structure characterized by a complete absence of rivalry among the individual's firms". In perfect competition, there are large number of buyers and sellers in the market. The individual firm as buyer and seller is simply a price taker. Product homogeneity: Another feature of the perfect competition is the product homogeneity. All products are perfectly same in terms of size, shape, taste, color, ingredients, quality, trademarks, etc.

Price Determination under Monopolistic Competition. Imperfect competition covers all situations where there is neither pure competition nor pure monopoly. Both perfect competition and pure monopoly are very unlikely to be found in the real world. In the real world, it is the imperfect competition lying between perfect competition and pure monopoly. The fundamental distinguishing characteristic of imperfect competition is that average revenue curve slopes downwards throughout its length, but it slopes downwards at different rates in different categories of imperfect competition. The monopolistic competition is one form of imperfect competition.

Short Run and Long Run Equilibrium under Perfect Competition (with diagram)

Our goal in this section is to see how a firm in a perfectly competitive market determines its output level in the short run—a planning period in which at least one factor of production is fixed in quantity. We shall see that the firm can maximize economic profit by applying the marginal decision rule and increasing output up to the point at which the marginal benefit of an additional unit of output is just equal to the marginal cost. Each firm in a perfectly competitive market is a price taker; the equilibrium price and industry output are determined by demand and supply. Figure 9. Price and output in a competitive market are determined by demand and supply. No matter how many or how few radishes it produces, the firm expects to sell them all at the market price. The assumption that the firm expects to sell all the radishes it wants at the market price is crucial.

Perfect competition is a comprehensive term which includes the following conditions: 1. Free entry and exit of firms 2. Existence of a large numbers of buyers and sellers 3. Commodity supplied by each firm is homogeneous 4. Existence of single price in the market Under this condition, no individual firm will be in the position to influence the market price of the product. According to Bilas, The perfect competition is characterised by the presence of many firms; they all sell the same product which is identical. The seller is the price- taker Features of perfect competition- Existence of a large number of buyers and sellers Absence of government controls Homogenous products Normal profits Free entry and exit of firms Existence of single price Perfect knowledge of the market Perfect mobility of factors of production The market price is flexible over a period of time Full and unrestricted competition It is an ideal market situation It is a rare phenomenon which does not exist in reality Price-Output Determination under perfect competition There are two well known approaches to pricing under perfect competition: 1.

Price Determination under Monopoly. Monopoly is that market form in which a single producer controls the whole supply of a single commodity which has no close substitute. From this definition there are two points that must be noted:. Thus single firm constitutes the industry. The distinction between firm and industry disappears under conditions of monopoly.

Price Determination under Perfect Competition (3 Periods)

Under perfect competition, price determination takes place at the level of industry while firm behaves as a price taker. It produces a quantity depending upon its cost structure. The industry under perfect competition is defined as all the firms taken together.

Refers to a time period in which quantity supplied of a product cannot be increased with increase in its demand. In simple terms, in very short period of time, the supply of a product is fixed. For example, a confectioner has 20 pastries at a particular time. After an hour, a customer requires 40 pieces of pastries. In such a case, the confectioner cannot prepare 20 more pastries in an hour and can only supply 20 pastries.

Price Determination Under Perfect Competition

A perfectly competitive market is a hypothetical market where competition is at its greatest possible level. Neo-classical economists argued that perfect competition would produce the best possible outcomes for consumers, and society. The single firm takes its price from the industry, and is, consequently, referred to as a price taker. The industry is composed of all firms in the industry and the market price is where market demand is equal to market supply. Each single firm must charge this price and cannot diverge from it. Under perfect competition, firms can make super-normal profits or losses. However, in the long run firms are attracted into the industry if the incumbent firms are making supernormal profits.

Perfect competition is a comprehensive term which includes the following conditions: 1. Free entry and exit of firms 2. Existence of a large numbers of buyers and sellers 3. Commodity supplied by each firm is homogeneous 4.

Perfect competition is a market structure that leads to the Pareto-efficient allocation of economic resources. Market structure is determined by the number and size distribution of firms in a market, entry conditions, and the extent of product differentiation. The major types of market structure include the following:. Perfect competition leads to the Pareto-efficient allocation of economic resources. Because of this it serves as a natural benchmark against which to contrast other market structures. However, in practice, very few industries can be described as perfectly competitive. Nevertheless, it is used because it provides important insights.


In the short run a firm under perfect competition is in equilibrium at that output at which marginal cost equals price or Marginal Revenue. But, in the long run for a perfectly competition firm to be in equilibrium, besides marginal cost being equal to price, price must also be equal to average cost.

  • In economics , specifically general equilibrium theory , a perfect market , also known as an atomistic market , is defined by several idealizing conditions, collectively called perfect competition , or atomistic competition. Arnou L. - 10.06.2021 at 00:54
