Perfect
competition is an industry which contains a lot of buyers and sellers and it
has no barriers to entry which means it is an open market or industry for
competitors to enter freely. For example, the people who are selling fruits,
vegetables, or meat in the competitive market. This industry is free for anyone
to come in as anyone who is interested to enter this industry is able to do so
because there are no brands to their products as they are homogeneous. Like fruits
has no brand. You can only differentiate it from their names or which
supermarket can you get them from.
On
the other hand, perfect competition is an industry which is a price taker. That
means the industry has no right to adjust the price of the products as the
price must be set according to the equilibrium market price. The demand of
these products is perfectly elastic since each firm’s or market’s outputs are
perfect substitute with one another. Then, the sellers have to know their
profits and losses in terms of short-run and long-run. So if the sellers or
firms are earning economic profit, they may enter new industry to maximize
their profit whereas if they are earning economic loss, they may have to exit
the industry.
