The demand for cigarettes is given by P 400 0.2Q. Cigarettes are manufactured at a constant marginal cost of 50 and sold in a competitive market. What is the quantity of cigarettes sold in equilibrium? Figure 1 Price 500- 450- 400- 350- 300- 250 200- QPrivate 1750 If cigarettes generate a marginal external cost of MEC = 0.05Q, what is the socially optimal level of cigarettes? QSocially optimal 1400 Using Figure 1 on the right that already shows the market demand curve to illustrate the private and social MC curves. Also, point out the private market quantity, the socially optimal quantity, and the social welfare cost. 1) Using the line drawing tool, illustrate the private marginal cost curve. Label this curve as 'MC'. 2) Using the line drawing tool, illustrate the social marginal cost curve. Label this curve as 'MSC'. (Hint: to plot this correctly you may first want to plot the socially optimal point 'B' in step 4 below) 3) Using the point drawing tool, illustrate the point that represents the profit-maximizing price and quantity. Label this point as 'A' 150 100 50 D 0 400 800 1200 1600 2000 Output

The figure below shows the market for a chemical, of which the production causes certain negative externalities in the form of pollution. Define MCP = marginal private cost, MCS = marginal social cost, D = market demand, P = price, and Q = quantity. 4 10 (a) (b) (c) (d) 100 P MC, ML D If the market is competitive, what is the equilibrium price and quantity? Is this equilibrium outcome socially optimal? In terms of the areas denoted by A, B, and C, what is the deadweight loss to society if the market is competitive? What can the government do to achieve the socially optimal level of pollution?

2) Suppose the demand curve for a rubber-based product is Q_D=225-0.5P, and the supply curve is Q_S=0.5P-15. If the external cost of the suit from the waste produced by the factory producing the item is MEC-Q, calculate: (a) Competitive price and quantity when there is no control over the waste disposal of the factory. (b) Price and quantity at the socially optimal level.

BN12.2 (a) Case: The market for dry cleaning is reflected by the demand and supply curves (Q is in thousands): Pa = 5-Q Ps= 2+2Q Producing dry cleaning creates ground water pollution with a constant marginal external cost of 1.2. Question: (a) Sketch a graph that shows the Dsoc, Spriv, Ssoc, Qopt (societal perspective) and DWL in an unregulated market (No need to label the values in the graph)?

2. Suppose that demand for a product is Q = 1200 - 4P and supply is Q = -240 +2 P. Furthermore, suppose that the marginal external damage of this product is $12 per unit. How many more units of this product will the free market produce than is socially optimal? Calculate the deadweight loss associated with the externality.

Only typed answer  You are an industry analyst that specializes in an industry where the market inverse demand is P = 100 - 3Q.

The supply and demand of sugar are given as           Qs = 5P,  Qd = 250- P   where Qs is tons supplied per year, P is the price per ton; Qd is tons demanded per year. Because of the pollution associated with production, marginal external costs of 40 are associated with each ton of sugar.  Assuming that sugar is sold in a competitive market,   What is the market price? How many tons of paper will be produced per year at that price? What is the efficient output of paper? What is the amount of total Pigouvian tax to achieve efficiency? What is the amount of total Pigouvian subsidy to achieve efficiency?

Consider a market where the demand curve is given by P = 190 – 0.2Q and the supply curve is given by P = 41 + 0.1Q. Production of this good generates an external cost as measured by the marginal external cost function MEC = 0.1Q. If the government wants to encourage firms to produce at the socially efficient level of output then how large should the per unit tax be? Enter a number rounded to two decimal places as necessary

Suppose the demand for a product is P = 400 - 0.25 Q and the supply of the product is P = 100 +0.75 P where Q is output and P is price. Suppose also that the marginal external cost (MEC) from production is constant and equal to 50$ per unit. What is the competitive (private) efficient level of output? What is the socially efficient level of output?
