Market situation where one
producer (or a
group of producers
acting in concert) controls
supply of a good or service, and where the
entry of new producers is prevented or highly
restricted.
Monopolist firms (in their attempt to maximize profits) keep the price
high and restrict the
output, and show little or no responsiveness to the needs of their customers. Most governments therefore try to
control monopolies by (1) imposing price controls, (2) taking over their
ownership (called 'nationalization'), or (3) by breaking them up into two or more
competing firms. Sometimes governments facilitate the creation of monopolies for reasons of national
security, to realize
economies of scale for competing internationally, or where two or more producers would be wasteful or pointless (as in the case of utilities).
Although monopolies exist in varying degrees (due to copyrights, patents,
access to materials, exclusive technologies, or unfair trade practices) almost no firm has a complete monopoly in the era of
globalization.
