# Nash equilibrium in this game

1. Time Magazine and Newsweek are two competing news magazines. Suppose that each company charges the same \$5.00 price for their magazines. Each wants to maximize its sales given the \$5.00 price. Each week, there are two potential cover stories. One is in politics. The other is on the economy. Sales of both companies are affected by the decisions on which story to place on their covers. The resulting sales for the two companies are given in the following table:

[SEE TABLE IN ATTACHED]

Assume the two companies make their decisions simultaneously
a. Construct a payoff table (by completing the table below) to show the sales (in dollars) each company would earn in each of the four decision situations.

[SEE TABLE IN ATTACHED]

b. Does Time Magazine have a dominant strategy? If so, what is it? Why?

c. Does Newsweek Magazine have a dominant strategy? Why? If so, what is it? Why?

d. What is the Nash equilibrium in this game? Explain why?

2. Suppose the Newsweek Magazine chooses and announces its cover story before Time Magazine chooses its cover. Construct a diagram (game tree) that shows the structure and payoffs of the game and answer the following questions (showing the diagram here is optional).
