Document Summary

Cartel: group of firms acting in unison in a collusion. Market feels the effects of a monopoly market. The cartel would decide on an outcome that maximizes the total profit and how to split production. Outcome is socially inefficient: the equilibrium for an oligopoly. If the duopolists individually pursue their own self-interest when deciding how much to produce: Total quantity produced is greater than the monopoly quantity. Output > price = owner increases production. Price approaches mc and q produced approaches the socially efficient level. Countries chose to have more arms than the other, yet want a world without arms. Each country chooses to continue the arms race, resulting in the inferior outcome with both countries at risk: common resources: Can be bad for both society and the cartel: maintaining monopoly profits. Lack of cooperation is desirable from society"s standpoint. Monopoly outcome is good for the cartel and bad for consumers.

2. Deviating from the collusive outcome

Mays and McCovey are beer-brewing companies that operate in a duopoly (two-firm oligopoly). The daily marginal cost (MC) of producing a can of beer is constant and equals $0.80 per can. Assume that neither firm had any startup costs, so marginal cost equals average total cost (ATC) for each firm.

Suppose that Mays and McCovey form a cartel, and the firms divide the output evenly. (Note: This is only for convenience; nothing in this model requires that the two companies must equally share the output.)

Place the black point (plus symbol) on the following graph to indicate the profit-maximizing price and combined quantity of output if Mays and McCovey choose to work together.

Monopoly Outcome PRICE (Dollars per can)QUANTITY (Thousands of cans of beer)DemandMRMC = ATC

When they act as a profit-maximizing cartel, each company will producecans and chargeper can. Given this information, each firm earns a daily profit of, so the daily total industry profit in the beer market is.

Oligopolists often behave noncooperatively and act in their own self-interest even though this decreases total profit in the market. Again, assume the two companies form a cartel and decide to work together. Both firms initially agree to produce half the quantity that maximizes total industry profit. Now, suppose that Mays decides to break the collusion and increase its output by 50%, while McCovey continues to produce the amount set under the collusive agreement.

Maysâs deviation from the collusive agreement causes the price of a can of beer to toper can. Mays's profit is now, while McCoveyâs profit is now. Therefore, you can conclude that total industry profit when Mays increases its output beyond the collusive quantity.
