As the number of firms in an oligopoly market grows larger, the price will approach:

Perfect competition occurs when there are many firms in a market offering differentiated products.

*Each firm reasons that the monopoly price ($24) earns them $48 000 each (2000 tickets each) . If one of them increases output by 1000, the price drops to $18 (midpoint) . At 5000 tickets, the firm that drops its price earns 3000 x $18 000 = $54 000. The other firm earns $36 000. The NE is for both firms to increase output to 3000. -Refer to Table 16-1. Assume that there are two profit-maximising ecotourist companies operating in this market. Further assume that they are not able to collude on the price and quantity of tickets they sell. How much profit will each firm earn when this market reaches a Nash equilibrium?

One economic example of prisoner's dilemma is overuse of a common resource like an oil-deposit.

The only market where firms need not to be concerned about balancing the price effect and the output effect when making production decisions is a:

Table 16.6 Two firms share a common fishery. One strategy available to the firms is to fish sustainably. This maintains a healthy breeding population of fish, and keeps the price of fish relatively high. The other strategy is to overfish. This reduces the breeding population and fish prices tend to fall. The game is represented in the following table. -Refer to Table 16-6. If firm B uses its dominant strategy, its profit at the Nash Equilibrium will be:

The story of the prisoners' dilemma contains a general lesson that applies to any group trying to maintain cooperation among its members.

Consider two cigarette companies, PM Inc. and Brown Inc. If neither company advertises, the two companies split the market. If they both advertise, they again split the market, but profits are lower, since each company must bear the cost of advertising. Yet, if one company advertises while the other does not, the one that advertises attracts customers from the other. -Refer to the information provided. What will these two companies do if they behave as individual profit maximisers?

The Nash equilibrium for a game can be a sub-optimal outcome for players when:

If there are many firms participating in a market, the market is either:

If identical products are sold by firms participating in a market, the market is which of the following? (i) perfectly competitive (ii) an oligopoly (iii) monopolistically competitive

While on holiday in Berserkistan, you are arrested and accused of spying for Australia. You are, of course, innocent. Your captors inform you that if you confess, you will receive a sentence of two years while your co-conspirator (whom you have never heard of) will receive a sentence of 20 years. If you both confess, you will each receive a sentence of three years. You are also told that your co-conspirator is being offered the same option. You suspect that there is not enough evidence to convict you unless your alleged co-conspirator confesses. If you are risk-averse, what should you choose to do?

Game theory is necessary for understanding competitive markets.

The logic of self-interest causes the duopoly's output level to be which of the following? (i) above the monopoly level (ii) above the oligopoly level (iii) below the competitive level

Table 16-7 The demand for a product that is produced at zero marginal cost is reflected in the table. (a) What is the profit-maximising level of production for a group of oligopolistic firms that operate as a cartel? (b) Assume that this market is characterised by a duopoly in which collusive agreements are illegal. What market price and quantity will be associated with a profit-maximising Nash equilibrium? (c) Assume that this market is served by three identical firms that operate as independent oligopolists (no collusive agreements). What market price and quantity will be associated with a profit-maximising Nash equilibrium? How does your answer differ from that in part b above?

Table 16-3 Imagine a small town in which only two residents, Robert and John, own wells that produce water for safe drinking. Each Saturday, Robert and John work together to decide how many litres of water to pump, bring the water to town, and sell it at whatever price the market will bear. To keep things simple, suppose that Robert and John can pump as much water as they want without cost; therefore, the marginal cost of water equals zero. The weekly town demand schedule and total revenue schedule for water are shown in the table. -Refer to Table 16-3. As long as Robert and John operate as a profit-maximising monopoly, what will their weekly revenue be?

In the absence of price-fixing, a monopoly will make more total profit than an oligopoly operating in an identical market.

Describe the output and price effects that influence the profit-maximising decision faced by a firm in an oligopoly market. How does this differ from output and price effects in a monopoly market?
