Consider our model of competition ECON 221(Bertrand Competition), spelled out in Case Study 2. Suppose we keep everything (in terms of demand curves, marginal costs, etc.). However, suppose we now have three firms instead of two. The game is otherwise the same (firm 1 moves first, then firm 2, then firm 3, etc.) (a) (10 points) What is the SPNE in this game? How does it compare to the solution we found in class? Explain. (b) (5 points) Does the solution to a model of Bertrand competition depend on the number of players? Explain. You don't have to solve the model in general, but your argument should be clear and detailed
