For each of the following characteristics, indicate whether it describes a perfectly competitive firm, a monopolistically competitive firm, both, or neither. (Note: If the characteristic describes neither, leave the entire row unchecked.) Characteristic Perfectly Competitive Monopolistically Competitive
Sells a product differentiated from those of its competitors
Has marginal revenue less than price
Earns economic profit in the long run
Produces at the minimum average total cost in the long run
Equates marginal revenue and marginal cost
Charges a price above marginal cost

Monopolistically Competitive

Monopolistically Competitive

Neither

Perfectly Competitive

both

Monopolistically Competitive

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.  

A monopolistic competition is when there are many firms selling differentiated products in an industry. A monopolistic competition has characteristics of both a monopoly and a perfect competition. the demand curve is downward sloping. it sets the price for its goods and services.

An example of monopolistic competition are restaurants  

When firms are earning positive economic profit, in the long run, firms enter into the industry. This drives economic profit to zero

If firms are earning negative economic profit, in the long run, firms leave the industry.  This drives economic profit to zero

in the long run, only normal profit is earned

In a monopolistic competitive market, firms always set the price higher than their marginal costs. As a result, the market cannot be productively efficient.

the answer is either c or b, i cant be to sure tho.
