Briefly explain using a graph whether given statement is true or false. “If firms in a monopolistically competitive industry are earning economic profits, new firms will enter the industry. Eventually, the representative firm will find that its demand curve has shifted to the left until it is just tangent to its average cost curve and it is earning zero profit. Because firms are earning zero profit at that point, some firms will leave the industry, and the representative firm will find that its demand curve will shift to the right. In long-run equilibrium, price will be above average total cost and each firm with make economic profit.”
Briefly explain monopolistic competition and provide an example of this in a South African industry.
Briefly explain any three key features of a Perfect Competitive and a Monopolistic market
