|
|
|
11 | | Public transportation systems are often regulated monopolies that receive subsidies. The subsidies exist primarily because |

|
|
13 | | Networking in the economy can lead to monopoly market structures because |
| | A) | to network effectively a firm must have government regulation protecting the heavy initial investments. |
| | B) | The more people using the product, the more valuable the product is to everyone. This means the first firm in the market may dominate the market. |
| | C) | Networks are another name for backward vertical integrating which leads to control of key inputs. |

|
|
|

|
|
21 | | Given the demand curve P = 500 – 5Q and a constant marginal cost of 100, if the firm is a single price profit maximizing monopolist, how much deadweight loss to society will result from the monopolists behavior? |
