We want to understand HOW Coke & Pepsi have managed to maintain very high profitability over the course of their existence

1. We want to understand HOW Coke & Pepsi have managed to maintain very high profitability over the course of their existence. There are 2 tools I want you to use to show.
   • Porter’s 5 forces: use this to explain how external forces (horizontal & vertical) have been defeated by the cola companies
   • Use repeated interactions game theory analysis to explain what’s going on between the two firms (note: it is important to understand global market developments)

What’s your opinion on how they’ve sustained these profits?
