Two Key difference between the monopoly and perfectly
competitive market are mentioned below:
- Entry and Exit of the Firm: In a perfect market condition the
firm is allowed easy entry and exit in the market. If a single firm
is making a supernormal profit in the market it will attract more
firms and it will continue to the point as long as the firm doesn't
make a supernormal profit anymore and same with the loss. A loss
will allow the firms to exit the market. But, in a monopoly, there
are several barriers to entry which doesn't allow the firms to
enter and exit.
- Level of production: In a perfectly competitive market, the
firm produces at a point where the allocation efficiency is there
i.e. the marginal cost of the last good produced is equal to the
price the consumer has paid for that good. But, in a monopoly,
there lies excess capacity and it means wastage of resources and no
allocative efficiency.
