What is a feature common to both Monopolistic-Competition and Oligopoly type of markets?
O productive efficiency will occur in both the short run and long run, a desirable economic property of markets.
many smaller sized firms can produce the good or service at lower cost per unit than larger sized firms, thus
large firms fail in the long run.
the demand curve for each firm is not going to be purely elastic, because products are at least slightly
different than potential rival firms' product and/or there may be some consumer brand loyalty.
Firms in both types of markets eventually will be broken up by government anti-trust laws and regulations.

You operate in a duopoly in which you and a rival must simultaneously decide what price to charge for the same homogeneous product. Assume each you and your rival can choose a “low price” or a “high price”. 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 million. If you charge different prices, the one charging the high price loses $5 million and the one charging the low price makes $5 million.
What is the Nash equilibrium for the non-repeated version of this game?
Now suppose the game is infinitely repeated. If the interest rate is 10%, can you do better than you could in the non-repeated version of this game? If your answer is “yes”, provide the players’ strategies and any other conditions that must hold.
