Suppose that demand is q = 10-p. Firms 1 and 2 compete in this market. Consider the following game. In the first period, both firms simultaneously choose capacities k1 and k2. Capacity cost per unit is constant and equal to 1. In the second period, firms compete by simultaneously choosing p1 and p2 with the restriction that the quantities sold cannot exceed the installed capacities, q1 <= k1 and q2 <= k2. There are no additional production costs in the second period.

(a) In the price competition stage, given the first period capacity choices (k1,k2) = (1,6) [k1 = 1 and k2 = 6], determine the two firms profits.

Final answer:

In a market with demand q = 10 - p and capacities k1 = 1 and k2 = 6, Firm 1 maximizes its profit by setting p1 at $9, leading to a profit of $8. Firm 2 can set p2 just below Firm 1's price to capture more market share and will have a profit of $47.94, assuming they set the price at $8.99.

Step-by-step explanation:

To determine the profits of firms in this two-stage game where they first choose capacities and then compete on prices, we need to analyze the second stage given the capacities k1 = 1 and k2 = 6. The market demand is q = 10 - p, where p represents the price. As there are no additional production costs in the second period, cost is only related to capacity, which is constant and equal to $1 per unit.

In the price competition stage, Firm 1 and Firm 2 will choose prices p1 and p2 respectively, and sell quantities q1 and q2. Since the capacities are constraints, q1 cannot exceed 1 and q2 cannot exceed 6. We presume the market will bear the lower of the two prices since the firms are selling a homogeneous product. If both firms set the price above $9, neither can sell because market demand is zero. Firm 1, with a maximum capacity of 1, has limited influence and will likely set p1 to yield one unit of sales, thus maximizing its profit at p1 = 9. Firm 2 can undercut this price slightly to capture the entire market up to its capacity of 6.

Firm 1's profit will be (Price - Average cost) * Quantity, which is (9-1)*1 = $8. Firm 2's profit, by setting a price just below Firm 1's, say at $8.99, would sell 6 units and its profit would be (8.99-1)*6 = $47.94.
