Answer 1

Answer:

Assumed in perfect Competition

Many buyers

Price taking behavior

Not assumed in perfect Competition

A small number of producers

Significant barriers to entry

Firms selling similar but different goods

Explanation:

A perfect competition is characterized by many buyers and sellers of homogenous goods and services. Market prices are set by the forces of demand and supply. There are no barriers to entry or exit of firms into the industry.  

In the long run, firms earn zero economic profit.  If in the short run firms are earning economic profit, in the long run firms would enter into the industry. This would drive economic profit to zero.  

Also, if in the short run, firms are earning economic loss, in the long run, firms would exit the industry until economic profit falls to zero.
