Monopolistic practices and the role of competition commissions in the Indian economy. There are many sellers of differentiated products, free entry and exit in the market, and each firm faces a downward sloping demand curve (Monopolistic Competition). The Competition Commission of India prohibits anti-competitive agreements and abuse of dominant positions to promote efficiency, productivity, choice and reduce costs. Advertising is used by firms in monopolistic competition to attract customers to differentiated products and establish brand names as a signal of quality.
