Figure14-2A Payoff Matrix Two firms, Nestlé and Mars, must decide how much chocolate to produce. The profits of the two firms are interdependent: each firm’s profit depends not only on its own decision but also on the other’s decision.

Both firms will be better off if they both choose the lower output, but it is in each firm’s individual interest to choose the higher output.
