Consider An Industry With An Incumbent Firm 1 And Potential Entrant Firm 2 Demand For Homogenous Good Is Given By P 1 (883.81 KiB) Viewed 12 times

Consider an industry with an incumbent (firm 1) and potential entrant (firm 2). Demand for homogenous good is given by p = 1 -Q. Potential entrant has marginal cost c-0.1, and a fixed sunk cost F. Incumbent marginal cost might be low (c= 0) or high (c = 0.1). Incumbent know the cost and entrant believes that it is low with a probability Pr(c = 0) = x. In the first period, firm 1 chooses its output. In the second period, firm 2 decides whether to enter or not. If firm 2 enters, it sinks its cost F and competes in quantity with the incumbent firm. Should Entrant know the incumbent's marginal cost, entrant will not enter if the incumbent firm is low cost and will enter if the incumbent is high cost. a) What is the Cournot equilibrium output when the incumbent firm is high cost? What is the Cournot equilibrium output when the incumbent firm is low cost? b) What is the maximum sunk cost for the entrant to enter if the incumbent firm is high cost? c) In a separating equilibrium, what is the equilibrium output for the incumbent firm in the first period? Does the incumbent firm successfully deter entry?
