(11) Consider a market with private marginal benefit (quantity demanded) given by PMB = 400 – 4Q, social marginal benefit given by SMB = 400 – 2Q and private marginal cost (quantity supplied) given by PMC = 40+4Q. Assume PMC = SMC. (a) Graph these PMB, SMB, and PMC curves. (b) What kind of externality is present? (c) Find the equilibrium price and quantity if producers only respond to private mar- ginal costs.

1. Suppose that Good X is sold in a perfectly competitive market. The supply curve is given by P=2Q, where P is the price of X per unit and Q is the quantity supplied. The demand curve is given by P=470-7Q. Suppose that the production process emits unpleasant smoke to the neighbourhood. The external marginal cost is estimated to be $24 per unit produced. The deadweight loss associated with this negative externality will be $ ????
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.
(a) Explain the difference between a positive externality and a negative externality and why each result in an equilibrium point that is not optimal for society. (b) which externality results in an equilibrium quantity that is higher than the optimal social quantity of a good? (c) how can the impact of the externality in part b be corrected?

Problem 5 refers to the following setup: The demand curve in a market is Q = 6-P. Firm A and B are the only sellers, their marginal costs are constant at 2 and 3 respectively, and there is no fixed cost. They produce identical goods. 5. a) What is the socially efficient outcome? (Specify the quantity for each firm.) b) Find the quantity produced by each firm and the price under Cournot competition. c) What is each firm's profit under Cournot competition?

Question 4 The private marginal benefit for commodity X is given by 10-X, where X is the number of units consumed. The private marginal cost of producing X is constant at $5. For each unit of X produced, an external cost of $2 is imposed on members of society. In the absence of any government intervention, how much X is produced? What is the efficient level of production of X? What is the gain to society involved in moving from the inefficient to the efficient level of production? Suggest a Pigouvian tax that would lead to the efficient level.
Consider the market illustrated in the figure to the right. Supply curve S₁ represents the private cost of production and demand curve D₁ represents the private benefit from consumption. Suppose consumption of this good creates a positive externality. Show how the externality affects the market. 1.) Use the line drawing tool to draw either a new supply (S₂) or demand (D₂) curve incorporating the positive externality in consumption. Properly label this line. 2.) Use the point drawing tool to indicate the market equilibrium price and quantity. Label this point 'Market equilibrium'. 3.) Use the point drawing tool to indicate the efficient equilibrium price and quantity. Label this point 'Efficient equilibrium'. Carefully follow the instructions above, and only draw the required objects. Price Quantity S₁ D₁ N
