  2. What level of output maximizes profit or minimizes loss?
  3. Should this firm operate or shut down in the short run? Why?
  4. Suppose that Wal-World and Tarbo are independently deciding whether to implement a new bar code technology or use the existing bar code. It is less costly for their suppliers to use one system, and the following payoff matrix shows the profits per year for each company resulting from the interaction of their strategies.

(Description of the graph: The payoff matrix shows two oligopoly companies: Wal-World and Tarbo, which are competing to increase their market share and payoffs. They have two strategies, which are playing existing bar code and new bar code. The two companies get different payoffs when they play different strategies. Existing bar code technology: upper-left box Wal-World earns $4 billion/Tarbo earns $3 billion. Upper-right box Wal-World earns $1 billion/Tarbo earns $2 billion. New barcode technology, lower-left box Wal-World earns $3 billion/Tarbo earns $1 billion. lower-right box Wal-World earns $2 bilion/Tarbo earns $4 billion.

  1. Does Wal-World have a dominant strategy? Briefly explain and justify your analysis.
  2. Does Tarbo have a dominant strategy? Briefly explain and justify your analysis.
  3. Is there a Nash equilibrium in this game? Briefly explain and justify your analysis.
