Competitive firms' profits are monopolistically competitive firms' profits in the long run.

Answer and Explanation:

Competitive firms' profits (economic profit) are same as monopolistically competitive firms' profits in the long run. Both competitive firms and monopolistic firms have zero profit in the long run. This is because for competitive firms, increased competition by entry of new firms creates high competition therefore infinitely homogenous divisible products hence zero economic profit in the long run. Also in monopolistically competitive firms, there is economic profit in short run but it soon becomes zero profit in the long run
