The players: American Airlines and United Airlines
The choice: cut fares by 50% or leave fares alone
If both airlines cut fares, each airline’s profit = $400 million
If neither airline cuts fares, each airline’s profit = $600 million
If only one airline cuts its fares, its profit = $800 million the other airline’s profits = $200 million
Draw the payoff matrix, find each airline’s dominant strategy, and find the Nash equilibrium. (put American on the top of the payoff matrix)
