ECON 30524 - Bocconi University. Strategic Decision Making and Markets BESS - 30458. GENERAL EXAM. Q&A
Consider a market in which two firms produce homogeneous goods. Market demand is given by Q = 300 − 2p. Firm 1 has capacity K1 = 130 while firm 2 has capacity K2 = 70. The marginal cost of product ion is the same for the two firms and is c1 = c2 = 30. STATEMENT TO DISCUSS: The pair of prices (p1 = 50; p2 = 50) is a Nash equilibrium of the game in which firms choose prices simultaneously.
