Hello I need help with this case study. Anybody ready to help?.

Question : 
Do an economic analysis of two giant competitor brands, Coke and Pepsi, in the context of them being rivals in the "Twenty-First Century" and use all the knowledge you have gathered over the last several weeks. Please do not make it a financial case.  It is to be an economics case study, utilizing the economic model of pure competition, monopolistic competition, oligopoly or monopoly. Use the most recent sources to make it more relevant. There is plenty of information out there including their home pages for starters. Please follow the same requirements as found in the first case (Week 3) and apply everything that you have learned in the class as long as it is relevant to the case.
