Initially there is one firm in the market for widgets. The firm has cost function C(Q)=3Q and marginal cost function MC(Q)=3. Market demand is given by P(Q)=20-3Q. What price will the firm charge? What quantity will it sell? Now a second firm enters the market. This firm has an identical cost function to the incumbent firm. What is the Stackelberg equilibrium output for each firm if firm 2 chooses its quantity second? What are the profits earned by each firm in the Stackelberg equilibrium? Which market do consumers prefer: monopoly or Stackelberg duopoly? Why?

Initially there is one firm in the market for widgets. The firm
has cost function C(Q)=3Q and marginal cost function MC(Q)=3.
Market demand is given by P(Q)=20-3Q.
1. What price will the firm charge? What quantity will it
sell?
2. Now a second firm enters the market. This firm has an
identical cost function to the incumbent firm. What is the
Stackelberg equilibrium output for each firm if firm 2 chooses its
quantity second?
3.What are the profits earned by...

A single firm produces widgets, with a cost function and inverse
demand function as follows, C(q) = 150+2q P(Qd) = 10−0.08Qd
(a) Calculate the monopolist’s profit-maximizing price,
quantity, and profit if he can charge a single price in the market
(single price monopolist).
(b) Suppose the firm wants sell units after your answer to (a)
at a lower price in a later time period (2nd-degree price
discrimination). What quantity will be sold for what price in this
second-tier market? Calculate...

A monopoly faces market demand Q = 30−P and has a cost
function C(Q) = Q^2
(a) Find the profit maximizing price and quantity and the
resulting profit to the monopoly.
(b) What is the socially optimal price? Calculate the
deadweight loss (DWL) due to the monopolist behavior of this firm.
Calculate consumer surplus (CS) and producer surplus (PS) given the
profit maximizing price.
(c) Assume that the government puts a price ceiling on the
monopolist at P =22. How...
