The main importance of anti-combined policy (antimonopoly
policy) is ideas to prevent industrial concentration or
monopolization, to achieve locative efficiency and to promote
competition. Even if many economists say that these are the main
aims of this policy some of them may argue that anti-combined
policies aren’t so effective and their goals aren’t always
achieved. The main important anti-monopolistic idea is that they
produce less output and charge higher prices than firms from
competitive market system. In pure competition firms produce
output quantity where P=MC. This equation is so important
because P represents benefit that society gains from extra unit
of output, while MC is the cost that society is ready to pay for
that extra unit. When this equation occurs (P=MC) society
doesn’t gain any higher total benefit by producing one more or
one less unit of output. However, a monopolist doesn’t maximize
profit by equating marginal benefit (not price) with marginal
cost. In this case, there is an under all
