    Nash equilibrium

    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    You operate in a duopoly in which you and a rival must simultaneously decide what price to advertise in the weekly newspaper. If you each charge a low price, you each earn zero profits. If you each charge a high price, you each earn profits of $3. If you charge different prices, the one charging the higher price loses $5 and the one charging the lower price makes $5.

    a. Find the Nash equilibrium for a one-shot version of this game.
    b. Now suppose the game is infinitely repeated. If the interest rate is 10 percent, can you do better than you could in a one-shot play of the game? Explain.
    c. Explain how "history" affects the ability of firms in this game to achieve an outcome superior to that of the one-shot version of the game.
