This document provides an overview of different market structures, including perfect competition, monopoly, and monopolistic competition. It defines a market as an arrangement where buyers and sellers can directly or indirectly buy and sell goods. Markets are classified based on geographical area, time period, and level of competition. Perfect competition has many small sellers and buyers, homogeneous products, free entry and exit, and price-taking firms. A monopoly has a single seller controlling the entire market supply of a unique product without substitutes. Monopolistic competition involves differentiated products, many firms and free entry. The document outlines characteristics and pricing dynamics for each market structure.

2. Outline of the Unit:
• Market
• Market structure
• Characteristics of perfect competition
• Monopoly
• Monopolistic competition

3. Concept of Market:
“An arrangement whereby buyers and sellers come in close
contact with each other directly or indirectly to sell and buy
goods is called as market”.
Analytically markets may be categorised into:
a) Product market: Product market or commodity market refers
to an arrangement in effecting buying and selling of commodities
or products.
b) Factor market: Factor market refers to the factors of
production such as land, labour & capital are transacted.
Classification of market structures:
The markets may be classified on the basis of different criteria
such as Geographical space or area, Time element and the nature
of Competition.

a) Perfect competition
b) Monopoly
c) Oligopoly
d) Monopolistic competition

6. Perfect Competition:
It refers to the market structures where competition among the
sellers and buyers prevails in its most perfect form.
In the perfectly competitive market a single market price prevails
for the commodity, which is determined by the forces of total
demand and supply in the market.
Under perfect competition every participant is a price taker.
Everyone has to accept the prevailing market price as
individually no one is in a position to influence it.
Characteristics of Perfect Competition:
a) Large number of sellers
b) Large number of buyers
c) Product homogeneity
d) Free entry and exist of firms
e) Perfect knowledge of market conditions
f) Perfect mobility of factors of production
g) Government non-intervention
h) Absence of transport cost element

7. Price Determination Under Perfect Competition:
In a market the exchange value of a product expressed in terms of
money is called as price.
In a market economy the equilibrium market price is determined by the
market forces.
Under perfect competition, there is a single ruling price-the equilibrium
price determined by the interaction of forces of total demand and
supply in the market.
Thus both the market or equilibrium price and the volume of
production in a market under perfect competition are determined by the
intersection of total demand and supply.
Possible Price

Total Supply

price
20 1000 10000 Downward
19 3000 8000 Downward
18 4000 6000 Downward
17 5000 5000 Neutral
16 7000 4000 Upward
15 10000 2000 Upward

9. Monopoly:
Monopoly is the other extreme form of market situation.
Pure monopoly is just opposite of perfect or pure competition.
Pure monopoly is a market structure in which there is only one
seller . He controls the entire market supply of a product. Because
there is no rival producing a close substitute, the monopoly firm
itself is an industry, so its output constitutes the total market
supply
Characteristics of Perfect Competition:
a) There exists only one seller but there are many buyers.
b) The monopoly firm is the industry.
c) There are many entry barriers such as STEPIN which do not
allow competitors to enter in the market.
d) Monopoly firm is a price maker
e) There are no closely competitive substitutes for the product
f) Monopoly is a complete negation of competition
g) Monopolist has a complete control over the market supply in
the absence of close substitute for his product

10. Types of Monopoly:
a) Pure Monopoly and Imperfect Monopoly
b) Legal, Natural, Technological & Joint Monopolies
c) Simple Monopoly and Discriminating Monopoly
d) Private Monopoly and Public or Social Monopoly

11. Monopoly Equilibrium in the Short Run:
The conditions for Equilibrium in Monopoly are the same as
those under perfect competition. The marginal cost (MC) is equal
to the marginal revenue (MR) and the MC curve cuts the
MR curve from below.

12. Monopolistic Competition:
It refers to the market structure in which there are a large number
of firms producing similar but identical products.
It is a blend of monopoly and competition.
It is similar to perfect competition in that it has a large number of
sellers but dissimilarities lie in its product differentiation.
Characteristics of Monopolistic Competition:
a) There are large number of sellers
b) There are large number of buyers
c) There is product differentiation.
d) Each seller resorts to advertising and sales promotion efforts.
e) It has two aspects i.e. Price competition and Non-price
competition.
f) Free entry
g) Selling costs
h) The group (Automobiles, Textiles, Footwear, Soaps,
Electronics, Computers, Cement, construction etc.)

13. Short-run Equilibrium of the Firm Under Monopolistic
Competition:
The firm maximizes its profits and produces a quantity where the
firm's marginal revenue (MR) is equal to its marginal cost (MC).
The firm no longer sells its goods above average cost and can no
longer claim an economic profit.

14. Long-run Equilibrium of the Firm Under Monopolistic
Competition:
In the long run, a firm in a monopolistic competitive market
will product the amount of goods where the long run marginal
cost (LRMC) curve intersects marginal revenue (MR). The price
will be set where the quantity produced falls on the average
revenue (AR) curve.
