INTRODUCTION
A market is one of many
varieties of systems, institutions, procedures, social relations and
infrastructures whereby parties engage in exchange. While parties may exchange
goods and services by barter, most markets rely on sellers offering their goods
or services (including labor) in exchange for money from buyers. It can be said
that a market is the process by which the prices of goods and services are
established.
For a market to be
competitive, there must be more than a single buyer or seller. It has been
suggested that two people may trade, but it takes at least three persons to
have a market, so that there is competition on at least one of its two
sides.[1] However, competitive markets rely on much larger numbers of both
buyers and sellers. A market with single seller and multiple buyers is a
monopoly. A market with a single buyer and multiple sellers is a monopsony.
These are the extremes of imperfect competition.
Markets vary in form,
scale (volume and geographic reach), location, and types of participants, as
well as the types of goods and services traded. Examples include:
• internet markets
• Ad hoc auction markets
• Markets for intermediate goods used
in production of other goods and services
• Labor markets
• International currency and commodity
markets
In mainstream
economics, the concept of a market is any structure that allows buyers and
sellers to exchange any type of goods, services and information. The exchange
of goods or services for money is a transaction. Market participants consist of
all the buyers and sellers of a good who influence its price. This influence is
a major study of economics and has given rise to several theories and models
concerning the basic market forces of supply and demand. There are two roles in
markets, buyers and sellers. The market facilitates trade and enables the
distribution and allocation of resources in a society. Markets allow any
tradable item to be evaluated and priced. A market emerges more or less
spontaneously or is constructed deliberately by human interaction in order to
enable the exchange of rights (cf. ownership) of services and goods.
Perfect competition
market
In economics, a perfect
market is defined by several conditions, collectively called perfect
competition. Among these conditions are
• Perfect market information
• No participant with market power to
set prices
• No barriers to entry or exit
• Equal access to production technology
The mathematical theory
is called general equilibrium theory. On the assumption of Perfect Competition,
and some technical assumptions about the shapes of supply and demand curves, it
is possible to prove that a market will reach an equilibrium in which supply
for every product or service, including labor, equals demand at the current
price. This equilibrium will be a Pareto optimum, meaning that nobody can be
made better off by exchange without making someone else worse off.[1]
Share and foreign
exchange markets are commonly said to be the most similar to the perfect
market. The real estate market is an example of a very imperfect market. Note
that the conditions for Perfect Competition mean that a perfect market cannot
be unregulated, since these preconditions for market function cannot at the
same time be products of the market, yet must be provided somehow.
Another characteristics
of a Perfect Market is normal profits, just enough to induce enough
participants to stay in the market to satisfy customer demand. The least
efficient producer may have very small profits, and be unable, for example, to
pay dividends to shareholders, while more efficient producers have larger
profits.
This attribute of
perfect markets has profound political and economic implications, as many
participants assume or are taught that the purpose of the market is to enable
participants to maximize profits. It is not. The purpose of the market is to
efficiently allocate resources and to maximize the welfare of consumers and
producers alike.
Basic structural characteristics:-
Generally, a perfectly
competitive market exists when every participant is a "price taker",
and no participant influences the price of the product it buys or sells.
Specific characteristics may include:
• Infinite buyers and sellers –
Infinite consumers with the willingness and ability to buy the product at a
certain price, and infinite producers with the willingness and ability to
supply the product at a certain price.
• Zero entry and exit barriers – It is
relatively easy for a business to enter or exit in a perfectly competitive
market.
• Perfect factor mobility - In the long
run factors of production are perfectly mobile allowing free long term
adjustments to changing market conditions.
• Perfect information - Prices and
quality of products are assumed to be known to all consumers and producers.[1]
• Zero transaction costs - Buyers and
sellers incur no costs in making an exchange (perfect mobility).[1]
• Profit maximization - Firms aim to
sell where marginal costs meet marginal revenue, where they generate the most
profit.
• Homogeneous products – The
characteristics of any given market good or service do not vary across
suppliers.
• Non-increasing returns to scale -
Non-increasing returns to scale ensure that there are sufficient firms in the
industry.[2]
Imperfect competition
market
In economic theory,
imperfect competition is the competitive situation in any market where the
conditions necessary for perfect competition are not satisfied. It is a market
structure that does not meet the conditions of perfect competition. [1]
Forms of imperfect
competition include:
• Oligopoly, in which there are few
sellers of a good.
• Monopolistic competition, in which
there are many sellers producing highly differentiated goods.
• Monopsony, in which there is only one
buyer of a good.
There may also be
imperfect competition due to a time lag in a market. An example is the “jobless
recovery”. There are many growth opportunities available after a recession, but
it takes time for employers to react, leading to high unemployment. High unemployment
decreases wages, which makes hiring more attractive, but it takes time for new
jobs to be created.
1.)OLIGOPOLY:-
An oligopoly is a
market form in which a market or industry is dominated by a small number of
sellers (oligopolists).[citation needed] Because there are few sellers, each
oligopolist is likely to be aware of the actions of the others. The decisions
of one firm influence, and are influenced by, the decisions of other firms.
Strategic planning by oligopolists needs to take into account the likely
responses of the other market participants
Characteristics of
oligopoly:
Profit maximisation
conditions: An oligopoly maximises profits by producing where marginal revenue
equals marginal costs.[1]
Ability to set price:
Oligopolies are price setters rather than price takers.[1]
Number of firms:
"Few" – a "handful" of sellers.[2] There are so few firms
that the actions of one firm can influence the actions of the other firms.[4]
Product
differentiation: Product may be homogeneous (steel) or differentiated
(automobiles).[3]
2.)Monopolistic
competition:-
It is a type imperfect
competition such that of one or two producers sell products that are
differentiated from one another as goods but not perfect substitutes (such as
from branding, quality, or location). In monopolistic competition, a firm takes
the prices charged by its rivals as given and ignores the impact of its own
prices on the prices of other firms.[1]
Monopolistically
competitive markets have the following characteristics:
• There are many producers and many
consumers in the market, and no business has total control over the market
price.
• Consumers perceive that there are
non-price differences among the competitors' products.
• There are few barriers to entry and
exit.[4]
• Producers have a degree of control
over price.
3.)Monopsony:-
In economics, a
monopsony is a market form in which only one buyer faces many sellers. As the
only or majority purchaser of a good or service, the "monopsonist"
may dictate terms to its suppliers in the same manner that a monopolist
controls the market for its buyer.
A monopsony is a market
condition where multiple sellers, [the majority of sellers in that market] all
have to sell to the same individual buyer because that buyer is buying a
significant portion of the entire market. This gives the buyer the advantage because
the buyer can keep asking each seller to match or undercut the competing
sellers prices, thus driving down the prices of the products in that market.
Monopoly market
A monopoly (from Greek
monos μόνος (alone or single) + polein πωλεῖν (to sell)) exists when a specific
person or enterprise is the only supplier of a particular commodity. Monopolies are thus characterized by a lack
of economic competition to produce the good or service and a lack of viable
substitute goods.[2] The verb "monopolize" refers to the process by
which a company gains the ability to raise prices or exclude competitors. In
economics, a monopoly is a single seller. In law, a monopoly is business entity
that has significant market power, that is, the power, to charge high prices.[3]
Although monopolies may be big businesses, size is not a characteristic of a
monopoly. A small business may still have the power to raise prices in a small
industry (or market).[4]
Monopolies typically
maximize their profit by producing fewer goods and selling them at higher
prices than would be the case for perfect competition. (See also Bertrand,
Cournot or Stackelberg equilibria, market power, market share, market
concentration, Monopoly profit, industrial economics). Sometimes governments
decide legally that a given company is a monopoly that doesn't serve the best
interests of the market and/or consumers. Governments may force such companies
to divide into smaller independent corporations as was the case of United
States v. AT&T, or alter its behavior as was the case of United States v.
Microsoft, to protect consumers.
Monopolies can be
established by a government, form naturally, or form by mergers. A monopoly is
said to be coercive when the monopoly actively prohibits competitors by using
practices (such as underselling) which derive from its market or political
influence (see Chainstore paradox). There is often debate of whether market
restrictions are in the best long-term interest of present and future
consumers.
In many jurisdictions,
competition laws restrict monopolies. Holding a dominant position or a monopoly
of a market is not illegal in itself, however certain categories of behavior
can, when a business is dominant, be considered abusive and therefore incur
legal sanctions. A government-granted monopoly or legal monopoly, by contrast,
is sanctioned by the state, often to provide an incentive to invest in a risky
venture or enrich a domestic interest group. Patents, copyright, and trademarks
are sometimes used as examples of government granted monopolies, but they
rarely provide market power. The government may also reserve the venture for
itself, thus forming a government monopoly.
Characteristics of
monopoly:-
• Profit Maximiser: Maximizes profits.
• Price Maker: Decides the price of the
good or product to be sold.
• High Barriers to Entry: Other sellers
are unable to enter the market of the monopoly.
• Single seller: In a monopoly there is
one seller of the good which produces all the output.[5] Therefore, the whole
market is being served by a single company, and for practical purposes, the
company is the same as the industry.
• Price Discrimination: A monopolist
can change the price and quality of the product. He sells more quantities
charging less price for the product in a very elastic market and sells less
quantities charging high price in a less elastic market.
