Question
Two identical firms lets call them firm 1 and firm 2 must decide simultaneously and independently whether to enter a new market and what product
Two identical firms lets call them firm 1 and firm 2 must decide simultaneously and independently whether to enter a new market and what product to produce if they do enter the market. Each firm, if it enters, can develop and produce either product A or product B. If both firms enter and produce product A they each lose ten million dollars. If both firms enter and both produce product B, they each make a profit of five million dollars. If both enter and one produces A while the other produces B, then they each make a profit of ten million dollars. Any firm that does not enter makes a profit of zero. Finally, if one firm does not enter and the other firm produces A it makes a profit of fifteen million dollars, while if the single entering firm produces B it makes a profit of thirty million dollars.
You are the manager of firm 1 and you have to choose a strategy for your firm.
(a) Set this situation up as a game with two players, firms 1 and 2, and three strategies for each firm: produce A, produce B or do not enter.
(d) Find all the pure strategy Nash equilibria of this game.
