Refer to the matrix, which shows the profit payoffs to each of two oligopolistic firms of following either a high- or low-price policy. Gamma's payoffs are in the lower left corner of each cell; Delta's in the upper right. If Gamma uses a high-price strategy and Delta uses a low-price strategy: |
| | A) | their profits will be the same |
| | B) | Gamma's profits will exceed Delta's profits |
| | C) | Delta would prefer to switch to a high-price strategy |
| | D) | Gamma would prefer to switch to a low-price strategy |

Suppose several firms in a purely competitive industry begin to experiment slightly with their product designs. This product differentiation allows them to modestly increase their prices and increase their short-run profits. The industry now more closely resembles: |
| | A) | pure monopoly |
| | B) | oligopoly |
| | C) | monopolistic competition |
| | D) | competitive monopoly |
|

Suppose only three airlines service a particular route. One of the airlines typically signals its price intentions through a daily posting on its internet site, which the other two quickly match. This best describes: |
| | A) | cost-plus pricing |
| | B) | price leadership |
| | C) | a cartel |
| | D) | game theory |
|
|
|

If an oligopolist's demand curve is kinked at the going price: |
| | A) | The loss in revenue from reducing output by one unit exceeds the gain in revenue from expanding output by one unit |
| | B) | The gain in revenue from expanding output by one unit exceeds the loss in revenue from reducing output by one unit |
| | C) | total revenue will remain constant if price is changed in either direction |
| | D) | profits will rise if price is increased but fall if price is decreased |

The monopolistically competitive firm illustrated in the diagram exhibits productive inefficiency because its profit maximizing: |
| | A) | output is not at the intersection of demand and marginal cost |
| | B) | output is not at the intersection of marginal cost and average total cost |
| | C) | price exceeds marginal revenue |
| | D) | price exceeds marginal cost |
|
|

In an oligopolistic industry: |
| | A) | firms behave strategically |
| | B) | output is produced at minimum average total cost |
| | C) | firms make price and output decisions without regard to the responses of their rivals |
| | D) | high profits will attract many new entrants to the industry |
|

A particular industry consists of three firms whose market shares are 50%, 30%, and 20%. The Herfindahl index for the industry is: |
| | A) | 33.3 |
| | B) | 100 |
| | C) | 2400 |
| | D) | 3800 |

Refer to the matrix, which shows the profit payoffs to each of two oligopolistic firms of following either a high- or low-price policy. Gamma's payoffs are in the lower left corner of each cell; Delta's in the upper right. If both firms make their decisions independently, the most likely outcome is: |
| | A) | $50 for both Gamma and Delta |
| | B) | $30 for both Gamma and Delta |
| | C) | $75 for Gamma and $20 for Delta |
| | D) | $20 for Gamma and $75 for Delta |
