. A monopolist has a cost function given by c(y) = 0.5y 2 and faces a demand curve given by P(y) = 120 − y.

What is its profit-maximizing level of output? What price will the monopolist charge?

• If you put a lump sum tax of $100 on this monopolist, what would its output be?

• If you wanted to choose a price ceiling for this monopolist so as to maximize consumer plus producer surplus, what price ceiling should you choose?

• Suppose that you put a specific tax on the monopolist of $10 per unit output. What would its profit-maximizing level of output be?

A monopolist has a total cost given by 9Q^2+18Q+21 and faces a demand curve given by -4Q+120. What is the profit-maximizing quantity the monopolist supplies the market? (Answer is 51/13, how did they get this?) What is the profit-maximizing price the monopolist sets in this market? ((Answer is 1356/13, how did they get this?)

A monopolist has the following cost function: C(q) = 800 + 8*q + 6*q2 It faces the following demand from consumers: P= 200 – 2*Q. There is another firm, with the same cost function, that may consider entering the industry. If it does, equilibrium price will be determined according to Cournot competition. How much should the monopolist optimally produce in order to deter entry by the potential entrant? How much would the monopolist produce if there were no threat of...
