Suppose the demand for donuts in Bethlehem is;

P = 10 – Q where Q = qA + qB

There are only two firms that sell donuts in Bethlehem, Firm A and Firm B. Each firm has the same cost function;

TC = 2 + q

a. Determine the Cournot equilibrium.

b. Explain why the intersection of the best-response functions is the Cournot equilibrium.

Expert Solution

Answer)

Cournot's Model is a example of oligopoly industry in which firms are assumed to determine their output simultaneously given that output produced by other firms remain constant. We use concept of Reaction Curve to arrive at cournot's equilibrium. Reaction curves represent profit maximization output produced by one firm for a given level of output produced by other firm. Cournot Equilibrium is a Nash Equilibrium.

1. Suppose that the market demand is described by P = A – B(Q+q) where P is the market price, Q is the output of the incumbent firm, and q is the output of the potential entrant to the market. The incumbent’s total cost function is C(Q) = c1Q, whereas the cost function of the entrant is C(q) = c2q+F. a. If the entrant firm observes the incumbent producing Q* units of output and expects this output level to be...

Suppose that consumer (retail) demand for a product is given by: Q=100−P, where Q is the quantity demanded and P is the price. The inverse demand curve (which gives the price as a function of the quantity demanded) is: P=100−Q. The marginal cost of production and average total cost of production are $26 per unit, and the marginal cost of distribution and average total cost of distribution are $10 per unit. Suppose the retail distribution is monopolized by another firm....

Suppose the demand curve for aluminum is Q = 800 – 10P, where P is the price per unit of aluminum and Q measures millions of units of aluminum. The private marginal cost of producing aluminum is MC = Q + 20, while the external marginal cost of producing aluminum is $10. Find the equilibrium price and quantity when the firm ignores the cost of the externality; Find the equilibrium price and quantity when the cost of the externality is...
