Two oligopolistic aluminium manufacturers are engaged in bitter competition with one another. Both firms, Big Aluminium Giant (BAG) and Little Aluminium Giant (LAG), are deciding whether to expand capacity or not. The table below shows payoffs for the firms under various scenarios. The first number in each cell is the payoff of LAG. Suppose the game is played once and each firm has to make its decision simultaneously. Does BAG have a dominant strategy? Explain clearly.

Suppose a monopolist knows it has two types of customers. The inverse demand for the customers in the first market is P
= 60 - Q while the inverse demand for the customers in the second market is P 50 2Q. The marginal cost is €10 in
both markets. Suppose the firm wishes to charge a two-part tariff to its customers but it cannot distinguish between the
customers in the first and second markets Calculate the entry (fixed) fee that the firm should charge in these
circumstances.
