Using a payoff matrix/table to determine the equilibrium outcome
Suppose there are only two firms that sell smartphones, Flashfone and Pictech. The following payoff matrix/table shows the profit (in millions of dollars) each company will earn, depending on whether it sets a high or low price for its phones.
Pictech Pricing
High
Low
Flashfone Pricing
High
10, 10
4, 12
Low
12, 4
9, 9
For example, the lower left cell shows that if Flashfone prices low and Pictech prices high, Flashfone will earn a profit of $12 million and Pictech will earn a profit of $4 million. Assume this is a simultaneous game and that Flashfone and Pictech are both profit-maximizing firms.
If Flashfone prices high, Pictech will make more profit if it chooses a price, and if Flashfone prices low, Pictech will make more profit if it chooses a price.
If Pictech prices high, Flashfone will make more profit if it chooses a price, and if Pictech prices low, Flashfone will make…
Two cigarette manufacturers repeatedly play the following simultaneous-move billboard advertising game. If both advertise, each earns profits of $0 million. If neither advertises, each earns profits of $10 million. If one advertises and the other does not, the firm that advertises earns $20 million and the other firm loses $1 million. If there is a 10 percent chance that the government will ban cigarette sales in any given year, can the firms “collude” by agreeing not to advertise?
One of the critical moments early on in the The Lord of the Rings trilogy is the meeting in Rivendell to decide who should take the One Ring to Mordor. Gimli the Dwarf won’t hear of an Elf doing it, whereas Legolas (who is an Elf) feels similarly about Gimli. Boromir (who is a Man) is opposed to either of them taking charge of the Ring. And then there is Frodo the Hobbit, who has the weakest desire to take the Ring but knows that someone must throw it into the fires of Mordor. In modeling this scenario as a game, assume there are four players: Boromir, Frodo, Gimli, and Legolas. (There were more, of course, including Aragorn and Elrond, but let’s keep it simple.) Each of them has a preference ordering, shown in the following table, as to who should take on the task of carrying the One Ring.
Of the three non-Hobbits, each prefers to take on the task himself. Each would prefer that other than themselves and Frodo, no one should take the Ring. As for Frodo, he doesn’t really want to do it…

Each firm can choose either a High quantity of 3 or a Low quantity of 2. The price for both firms is 9-Q, where Q is the sum of both their quantities. Costs are zero; the profit is simply price times quantity. For example, if firm 1 chooses High and firm 2 chooses Low, then price is 9-(3+2)=4; payoff for firm 1 is 12 while payoff for firm 2 is 8.
