In this module, we introduce the basic concepts of game theory and use strategic games to learn competitor analysis. We answer “what is a strategy?” and look at the different ways to determine a best or dominant strategy. We also discuss the concepts of Nash Equilibrium and Prisoners’ Dilemma - and learn that it is important to anticipate and take into consideration the actions of the other players. Lastly, we analyse what happens when we change the game from simultaneous (where everybody acts at the same time) to sequential (where players move after each other).
