Externalities-analysis and policy design: Suppose that in a competitive market, demand is given by the equation P = 600 - Q, and supply is given by the equation P = 160 + Q, where P is price and Q is quantity of some good or service. Production of each unit of output Q leads to a marginal external cost of $50, caused by pollutants emitted by the production of Q. If we add this marginal external cost to the market information, the equation for the social-cost supply curve is given by P = 210 + Q.

b. Compute the monetary value of the deadweight social loss from the market failure that occurs if society lets firms to continue to produce negative externalities without regulation.
