INTRODUCTION:
Now we are starting the third unit. This unit will give you all the details of the
different market structure. After reading this unit you will be able to know about
the different types of markets.
The number of firms and the level of product differentiation are useful parameters for
classifying various market structures. The level of competition also gets influenced by
product and production related factors, potential competitors, number of buyers and their
behaviour and the governmental policies.
We are now ready to analyze the various market
forms in greater detail. That will be attempted in the subsequent units in this block.
Meaning of market:
A market is a group of people and firms which are in contact with
one another for the purpose of buying and selling some product. It is not necessary that
every member of the market be in contact with each other.
Markets and competition

2. While all of us often use the word-'Market’, we-do' Do
not realize that very few, markets possess a well defined place in a geographical area or
have a postal address. The Bombay, Stock Exchange is, one such market with a building
and an area earmarked for transacting shares.
The central phenomenon in the functioning of any market is competition. Competitive
behavior is molded by the market structure of the product under consideration. It
is therefore necessary to have a thorough understanding of this concept.
Meaning of Market structure:
A simple definition of this concept can be found in
Pappas and Hirschey (1985).
According to them "Market structure refers to the number and size distribution of buyers
and sellers in the market for a good or service. The market structure for a product not

3. includes firms and individuals currently engaged in Buying and selling but also
the potential entrants.
CLASSIEFICATION OF MARKET STRUCTURES:
Markets are traditionally classified
into four basic types. These are :
Perfect competition is characterized by a large number of buyers and sellers of
an essentially identical product. Each member of the market, whether Buyer or seller, is
so small in relation to the total industry volume that he is unable to influence the price of
the product. Individual buyers' and sellers are essentially price takers. At the ruling price
a firm can sell any quantity. Since there is free entry and free exit, no firm can earn
excessive profits in the long run.
Monopoly: In this situation there is just one producer of a product. The firm has
substantial control over the price: Further, if product is differentiated and if there are no
threats of new firms entering the same business, a monopoly firm can manage to earn
excessive profits over along period.
Monopolistic competition : It is coined by E.M. Chamberlin “implies a market structure
with a large number of firms selling differentiated products”. The differentiation may be
real or is perceived so by the customers. Two brands of soaps may just be identical but
perceived by customers as different on some fancy dimension like freshness. Firms
in such- -a market structure have some control over price! By and large they are unable
to earn excessive profits in the long run. Since the whole structure operates on perceived
product differentiation entry of new firms cannot be prevented. Hence, above
normal profits can be earned only in the short run.
Oligopoly is a market structure in which a small number of firms account for the whole
industry's output. The product mayor may not be differentiated. For example only 5 or 6
firms in India constitute 100% of the integrated steel industry's output. All of, them
market almost identical products. On the other hand, passenger car industry with only
three firms is characterized by marked differentiation in products The .nature of products is
such that very often one finds entry of new firms difficult. Oligopoly is characterized by
vigorous competition where firms manipulate both prices and volumes in an attempt to
outsmart their rivals. No generalization can be made about profitability scenarios.
PARAMETERS OF MARKET STRUCTURES:
Now its clear that all the
market structures use only two parameters as distinguishing factors-number of
firms and degree of product differentiation. Other factors like product characteristics
and entry of new firms are also important but these determine the level of
competition in a given market structure.
In the real situation we will only find the imperfect market situation, and other market
situations like perfect competition, monopoly, and oligopoly are all myth. From the

4. above it is also clear that all these market structures can be classified in only two
fundamental forms-Perfect Competition and Imperfect Competition. Under this
classification Monopoly, Oligopoly and Monopolistic Competition are treated as special
cases of markets which are less than perfect. Thus these forms illustrate the degree of
imperfection in a market by using the number of firms and product differentiation
as basic criteria.
A convenient and effective classification scheme depicting types of competitive market
structures is shown in the diagram. A close look at the diagram reveals that most real world
markets are neither perfectly competitive or perfectly monopolistic. Most
industries that we come across can be classified in the realm of imperfect competition.

FACTORS DETERMINING THE NATURE OF COMPETITION
As we have seen that the number of firms and product differentiation are extremely crucial
in determining the nature of competition in a market. It has been tactically assumed that
there are a large number of buyers. What would happen if there are several firms
producing a standardized product but only one buyer? Obviously,' the buyer would
control the price, he will dictate how much to buy from whom. The entire price volume
decision takes on a different qualitative dimension. Similarly, product features and
characteristics the nature of production system the possibility of new entrants in a market
have profound impact on the competitive behavior of firms in a market. Since the 'entry'
of new entrants has special relevance in business behavior we reserve it to the
next section and deal with other issues in the present one.
Effect on buyer
We have already referred to the case where there is only one buyer. Such
situation is defined as monopoly. For example, there are just six firms in India
manufacturing railway wagons all of which supply to just one buyer The Railways. Such
a situation can also exist in a local labor market where' a single large firm is the only
provider of jobs for the people in the vicinity. A recent example is the new
petro- chemicals complex that is coming up in the rural parts of coastal Maharashtra.
More frequently encountered in the Indian markets is a case of a few large buyers,
defined as Oligopoly. The explosives industry which makes detonators and commercial
explosives has three major customers Coal India Ltd. (CIL), Department of Irrigation and

6. various governmental agencies working on road building activities of these, just one
customer, CIL takes nearly 60% of the. industry's output. There are about 10 firms. In the
industry which negotiate prices and quantities 'with CIL to finalize their short term-plans.
Most industries manufacturing heavy engineering equipment are typified in India by a
few manufacturers and few buyers with the Government being the major one. Price and
volume determination in such products often takes the form of negotiation across table
rather than the operation of any market forces. Since the members in the whole, market
inclusive of buyers and sellers are not many very often they know each other. In other
situations like the consumer goods firms have no direct contact with their customers.
Production Characteristics
Minimum efficient scale of production in relation to the overall industry output and
market requirement sometimes playa major role in shaping the market structure. Why
there are no more than say , 5 or 10 integrated steel plants even in an advanced country like
the U.S.A. can be partly explained by this factor. Since the minimum economic size of such
a steel plant is a few million tones, the entire world steel industry can have no more than
JOO efficient and profitable firms. Thus every country has only a handful of

7. steel plants. On the other hand, when one comes to re-rolling mills which take the steel
billets or bars as input, the minimum efficient size comes down considerably, and given
the existing demand, several firms can be seen to operate.
Further, the minimum size does not remain constant but changes drastically with
technological advancements, When technical changes push up the economic size of
a plant one notices that the number of firms decline over time. This can be noticed in
some process industries like synthetic fibre. Conversely, technological innovations may
make it possible for smaller sized. plants to become economically viable. In such a case
a lot of new entrants come and soon the market becomes highly competitive. Notice the
personal computers entry in India.
Apart from minimum plant size factors like availability of the required raw
material, Skilled labour etc. can also mould the market structure. Presently only one
Indian source (IPCL) provides all the raw material for plastic products. Like wise,
enough skilled people are not available work on the sophisticated machines. These
factors sometimes restrict output and push up prices even though adequate market
potential for expansion exists.
Product Characteristics
The above example referred to market situations with CTV and detergent powder
as product examples. Both these markets have many firms and the products
are differentiated. But in case of CTV, there are no close substitutes (BWTV) being a
poor one, whereas, there are many substitutes to a detergent powder (bar soaps; chips,
cakes). Therefore one notices more violent competition in the detergent Market than in
the CTV. market. In the CTV industry firms are competing with each other's products but
in the detergent market the firms are competing with other substitute products as
well. Of course you may remind us of the customer income constraint but even
with that there should be no difficulty in appreciating the differences in the degree of
c6mpet1tiveriess in these two markets. Similarly when two locations are connected by
road and rail, firms engaged in passenger bus service are not only computing with
themselves but also with an alternate mode of transport. . .
The physical characteristics or a product can also influence the competitive structure of
its market. If the distribution cost is a major element in the cost of a product, competition
would tend to get localised. Within a given region firms would compete and
make attempts to set up several plants around all the major markets in a bid to
show there presence in all the territories. Similarly, for perishable products, the
competition is invariably local
Conflict between physical characteristics and minimum economic size,
An interesting question arises in the case of a product like cement . for reason of
minimizing the transport costs on raw materials, most cement plants in the country are
located near mine sites. A large efficient plant near a mine site can manufacture cement at
the optimum cost, but the local demand is never large enough. If such a plant has to sell

8. In far away markets (from Gujarat to Kerala, for example) the transport costs can be quite
high. Customers located in such areas will always buy cement at a much higher price.
The government partly offsets this by using the mechanism of levy price which is the
same throughout the country.
BARRIERS TO ENTRY
In a classic book J .S. Bain (1956) analyzed the character and significance of the
condition of entry in manufacturing industries. Till that time, most analyses of
how competition works gave little. emphasis to the force of the potential or
threatened competition of possible new competitors. The attention was simply
focused on the competition among firms already established in an industry. Lately,
however the meaning of competition is inclusive of potential entrants.
The existence or otherwise of 'entry barriers' in a given industry has profound impact on
its performance and the behavior of firms in it.
If has been found that the firms in an industry are always worried about the possibility of
a new entrant. If the existing number is few then the degree of insecurity will be
correspondingly higher. To be sure, the existing firms, especially in an oligopoly, have ..
some advantages over the potential, entrant. But, because of the threat of new entrants,
the existing members cannot, exploit these advantages (by raising prices continuously)
beyond a point. What that point is and when the new entrants would find it profitable to
break the entry barriers are also not known. One thing is clear, that this potential
competition always puts a check on the pricing strategies of oligopolists.
What can act as an entry barrier?
Anything that retains the competitive advantages of the existing firms in an industry can
act as a barrier to those' desirous of entering it. Some of the commonly
encountered aspects are indicated below.
High Initial Investment
A new passenger car plant with a capacity to assemble say 50,000 automobiles
per annum can cost around Rs.1O0,crores. You know that not many firms have the
capacity to mobilize resources of that order. Naturally, there are high entry
barriers to the automobile market due to high level of initial investment. For similar
reasons, one does not find too many integrated steel plants coming up too often. On the
other hand, it takes only a few lakhs of rupees to set up a biscuit making unit.
The barrier on account of investment is quite low in such industries.
Economies of Scale in Non-production Activities
Scale economies are not restricted to manufacturing. These extend to distribution,
marketing and advertising. Consumer products like soaps, toothpastes display
considerable economies of scale in marketing and distribution. A nation-wide presence in
these industries presupposes an efficient and penetrating distribution network, high order
of brand related marketing skills and ability to service a fairly differentiated product line.

9. Thus, one may find numerous local soap makers but there are substantial entry barriers to a
new national brand penetrating the market.
Technology, Patents and Research
The ability to possess and commercially exploit certain specialized technology is one
more source of entry barrier. Specially chemicals, drugs, plastics are some of the
industries where the difficulty of developing a new. product or a process is well
understood. These are knowledge related factors. It is very difficult to penetrate
an industry where a few existing firms have a strong research base and a large
pool of product related patents. New entrants in such industries are often the employees
of the existing firms breaking away to form a new entity.
Switching Costs
Take an industry like earthmoving machinery. For such an industry each firm has a few
large customers like contractors, project authorities or coal mines. Consider that a
customer has a fleet of say 10 machines of a given brand. When he replaces one machine
or augments his fleet, more likely the choice would fall on the same brand. For him it
means a familiar machine, known operational details, already trained operators and a host
of other things like spare parts stocks. Thus, the cost of switching to a new brand can be
fairly high,' These costs can act as entry barriers. Along with earthmoving machines the
customer also has related equipment like loaders and dump trucks which he had
purchased on the ground of compatibility with a given brand of the main machine.
.
Take the case IBM. Why does every other personal computer.(PC) that one come
as across claims to be an IBM compatible. It has to be so, because all the
software is developed by using IBM standards. The PC cannot work without
software. By developing industry level standards, IBM has created 'high switching
costs' in an attempt to create entry barriers.
You will have notice a that' in oligopoly situations, firms should strive towards creating
high entry barriers, if the industry does not possess those necessary characteristics. This
is precisely what happens. If there are low entry barriers, new firms enter soon and the
profitability of the existing firms drops. Notice the state of the pocket calculator industry.
There, are virtually no entry barriers and with the existence of cheap smuggled products,
it is impossible to create them. As a result, most large firms are almost out of this market
leaving it open for the small scale units.

THE ROLE OF GOVERNMENT POLICY
,All governments, whether in India or abroad, impose taxes and duties. What is special
about the Indian governmental policies is their ability to control price, ,quantity of
production, distribution choice of product, location and almost every business decision of
a firm. Some reference to these have been made in the previous sections. Presently we
shall see the role of government policy in a synoptic way. Later, a full unit in Block No.
5 will talk about the regulatory environment in detail.
,"
Through its industrial licensing policies the Central Government has control over
the following business decisions:
1 Choice of the product
2 Scale of production (capacity)
3 Location of production
4 Choice of technology
The policy on foreign collaborations also regulates the aspects pertaining to choice
of technology. Import policies can have significant impact on the types and quantities of
raw materials that would become available for production. Choice of machinery is also
guide by the import regulations in force.
Through levy of customs and excise duties, the price of the end products as well as the
raw materials gets affected. Some industries like sugar aluminum, steel, edible.
oils, cement are subject to price controls. These are administered through various Acts
and, the job of determining prices is often entrusted to the Bureau of Industrial
Costs and Prices under the Ministry of Industry. Firms in these industries are thus partly
guided by market forces and partly by the Ministry in regard to their pricing decisions.
Apart from these, several state governments have their regulations for promoting
(or restricting ) 'the growth bf certain industries. All things considered, the job of
the business manager is made quite difficult in the Indian environment.
Ironically, government steps ill to correct certain imperfections in the market but
in the process adds a few of its own. The existence of many industries with only few
firms is mainly attributable to the government policies which have acted as entry
barriers for a long period of time. The picture is changing rapidly. There are fair
chances that in the future market related forces would operate more on the price volume
decisions of the firms, than the government, policy related factors.
