The demand for fabric is Q = 40 - P/2. The private cost of producing fabric is C(Q) = Q2, with private marginal cost PMC = 2Q. Washing and dyeing fabric causes water pollution with total damages CE(Q) = Q2/2, so external marginal costs of EMC = Q.

Calculate the net benefits under competitive equilibrium and under efficient equilibrium, as well as the DWL. What can you conclude from the value of DWL (which equilibrium is the right level or production)?

Expert Solution

Deadweight loss under competitive equilibrium is 40

There is a deadweight loss under competitive equilibrium. So, we can conclude that efficient equilibrium is the right level of production.

We can also conclude that the efficient equilibrium is the right level by looking at the net benefit in each type.

In competitive equilibrium, the net benefit is 600 whereas in efficient equilibrium, the net benefit is 640. Therefore, the right level is efficient equilibrium.

Consider a market where inverse demand is given by P = 40 − Q, where Q is the total quantity produced. This market is served by two firms, F1 and F2, who each produce a homogeneous good at constant marginal cost c = $4. You are asked to analyze how market outcomes vary with industry conduct: that is, the way in which firms in the industry compete (or don’t). First assume that F1 and F2 engage in Bertrand competition. 1....

A firm's total cost of producing Q units of output is C (Q) = 79 + 20Q. The inverse demand curve for the firm's product is P(Q) = 100-Q, where P denotes the price of the product.

A firm's total cost of producing Q units of output is C (Q) = 79 + 20Q. The inverse demand curve for the firm's product is P(Q) = 100-Q, where P denotes the price of the product. a) If the price of the product is set equal to the firm's marginal cost, what profit will the firm earn? b) If the firm charges a two-part tariff (a fixed fee plus a per unit price), how large is the fixed fee?

The demand function for iPhone is Q(p) = 100 – P and the cost function is C(Q) = 5Q. Apple initially sets the price of iPhone to be p1; after one-year Apple lowers the price to p2. Suppose the price decrease is not anticipated by the consumers. The number of consumers buying the iPhone at p1 is q1, and the amount buying at p2 is q2, where q1=Q(p1) and q1+q2=Q(p2). Find the profit-maximizing p1 and p2 and the corresponding q1...
