You are operating a firm in a perfectly competitive market. In the short run, you have fixed costs of $30. Your variable costs are given in the following table:

Q | TVC |

0 | 0 |

1 | 70 |

2 | 120 |

3 | 150 |

4 | 190 |

5 | 270 |

6 | 360 |

A monopolist faces a demand curve given by:

P = 105 – 3Q, where P is the price of the good and Q is the quantity demanded. The marginal cost of production is constant and is equal to $15. There are no fixed costs of production.

A) (2 points) What quantity should the monopolist produce in order to maximize profit?

B) (2 points) What price should the monopolist charge in order to maximize profit?

C) (2 points) How much profit will the monopolist make?

D) (2 points) What is the deadweight loss created by this monopoly (hint: compare the monopoly outcome with the perfectly competitive outcome).

E) (2 points) If the market were perfectly competitive, what quantity would be produced?

**3.**

Suppose a competitive firm can sell its output for $6 per unit. The following table gives the firm’s short run production function.

Labor | Output |

1 | 20 |

2 | 50 |

3 | 90 |

4 | 110 |

5 | 120 |

6 | 124 |

In the table below, you will determine several points on the firm’s demand curve for labor. To do this, you must determine how many workers the firm should hire for different values of the wage rate in order to maximize profit. Complete the table below:

Wage Rate Per Worker | Quantity Demanded of Workers |

$50 | |

$80 | |

$100 | |

$150 |
