a market structure with only a single seller of a

commodity
or service dealing with a large number of buyers. When a

single
seller faces a single buyer, that situation is known as bilateral

monopoly.



The most
important features of market structure are those, which

influence
the nature of competition and price determination. The key

element in
this segment of market organization is the degree of seller

concentration,
or the number and size distributions of the sellers. There is

monopoly
when there is only one seller in an industry, and there is

competition
when there are many sellers in an industry. In cases of an

intermediate
number of sellers, that is, something between monopoly and

competition,
there can be two sellers (duopoly), a few sellers (oligopoly),

or many
sellers (atomistic competition).



Today the
term monopoly is usually extended to include any group

of firms,
which act together to fix prices or levels of production. Complete

control of
all output is not necessary to exercise monopoly power. Any

combination
of firms, which controls at least 80 percent of an industry's

production,
can dictate the prices of the remaining 20 percent.



Aside from private
monopolies, there are public monopolies. One

example of
a public monopoly in the United
States is the nonprofit postal service. There is also the «natural» monopoly,
which exists when it is more efficient, technically, to have a single seller.
