Choose a product or service in a country of your choice that you believe to be supplied by an industry characterised by monopolistic competition, and justify why you believe the model of monopolistic competition applies. What are the implications of that market structure of monopolistic competition for customers of the product, and for firms producing the product, in terms of prices, costs of production, profits, product differentiation and innovation? What might cause the long-run equilibrium of an industry in monopolistic competition to be disturbed, and how will long-run equilibrium be regained?
