Suppose there are 2 firms in a market. They face an aggregate demand curve, P=400-.75Q. Each firm has a Cost Function, TC=750+4q (MC=4). a. If the 2 firms could effectively collude, how much would each firm produce? What is aggregate output? What is price? What are the profits for each firm? Provide a graph illustrating your answer. b. Suppose instead that the firms compete in Quantity (Cournot Competition). Calculate each firm's best-response function using the formulae provided in the book. What is the Nash equilibrium level of production for each firm? What is the equilibrium price? What are the profits of each firm? Provide a graph illustrating your answer. c. Suppose instead that firm A is a Stackelberg leader and gets to choose quantity first. Calculate each firm's best-response function. What is the Nash equilibrium level of production for each firm? What is the equilibrium price? What are the profits of each firm?

Answer #1

Equilibrium condition is where MR = MC.

Under cournot model, firms compete on quantities.

In Stackelberg model, one firm act as leader and other follows. Due to this, leads has first mover advantage.

Suppose duopolists face the market inverse demand curve P = 100 - Q, Q = q1 + q2, and both firms have a constant marginal cost of 10 and no fixed costs. If firm 1 is a Stackelberg leader and firm 2's best response function is q2 = (100 - q1)/2, at the Nash-Stackelberg equilibrium firm 1's profit is $Answer

Two firms compete in a Bertrand setting for homogeneous products. The market demand curve is given by Q = 100 – P, where Q is quantity demanded and P is price. The cost function for firm 1 is given by C(Q) = 10Q and the cost function for firm 2 is given by C(Q) = 4Q. What is the Nash-Equilibrium price? What are the profits for each firm in equilibrium?

The market demand function is Q=10,000-1,000p. Each firm has a marginal cost of m=$0.16. Firm 1, the leader, acts before Firm 2, the follower. Solve for the Stackelberg-Nash equilibrium quantities, prices, and profits. Compare your solution to the Cournot-Nash equilibrium. The Stackelberg-Nash equilibrium quantities are: q1=___________ units and q2=____________units The Stackelberg-Nash equilibrium price is: p=$_____________ Profits for the firms are profit1=$_______________ and profit2=$_______________ The Cournot-Nash equilibrium quantities are: q1=______________units and q2=______________units The Cournot-Nash equilibrium price is: p=$______________ Profits for the...

Given an aggregate demand function Q( p) = 54 − 2 p and a cost function for each firm of C(q) = 3q^ 3+ 29. (Hint: we must have q ≥ 0, so when you look at the roots, pick the non- negative one.) (a) Suppose there are 36 firms. Setup and solve the firm profit maximization problem. Then solve for the price, quantity, and profits for each individual firm and aggregate equilibrium quantity, given that the number of firms...
