he figure below shows the payoff matrix for two firms, Firm 1 and Firm 2, selecting an advertising budget. For each cell, the first coordinate represents Firm 1's payoff and the second coordinate represents Firm 2's payoff. The firms must choose between a high, medium, or low budget.
Payoff Matrix | Firm 1 | |||
High | Medium | Low | ||
Firm 2 | High | (0,0) | (5,5) | (15,10) |
Medium | (5,5) | (10,10) | (5,15) | |
Low | (10,15) | (15,5) | (20,20) |
Use the figure to answer the following questions. Note: you only need to submit scratch work for the mixed strategy calculations.
This game can be simplified by eliminating strategies that are strictly dominated.
Which budget will Firm 1 never select (High, Medium, or Low)?
Which budget will Firm 2 never select (High, Medium, or
Low)?
There are two pure strategy Nash equilibria in this game. What are they? Submit the answers as coordinates. For example: (High, Low) represents the strategy where Firm 1 plays 'High' and Firm 2 plays 'Low'.
Pure Strategy Nash Equilibrium 1:
Pure Strategy Nash Equilibrium 2:
This game also has a mixed strategy. What is the mixed-strategy Nash equilibrium? Enter your answers as decimal numbers, rounding to two digits when needed.
Firm 1 will set a 'High' budget with probability:
Firm 1 will set a 'Medium' budget with probability:
Firm 1 will set a 'Low' budget with probability:
Firm 2 will set a 'High' budget with probability:
Firm 2 will set a 'Medium' budget with probability:
Firm 2 will set a 'Low' budget with probability:
