The Coca Cola company faces negative publicity about cold drinks being used as toilet cleaners, which has led to a decrease in market share. The oligopoly market structure dominated by Coca Cola and Pepsi means that the two companies compete through advertising rather than prices. To regain market share, Coca Cola should focus on branding, product differentiation (such as Coke Zero), and partnerships with organizations that host events. This will help increase market share by appealing to different age groups and demographics. Furthermore, Coca Cola's elasticity of demand shows a high income elasticity, which means that high-income individuals prefer Pepsi over Coca Cola, but the cross-price elasticity suggests that people are more likely to shift to Pepsi when Coke is costlier, indicating that Coke is perceived as a higher-quality product.
