Consider a firm that emits pollution into the air. Suppose that the marginal damage costs associated with the emissions are given by MDC-15+ 4c, where e is the quantity of the emissions. The firm's marginal costs of abatement are given by MAC 1200 - 20 c. (a) (b) (c) = Determine the quantity of emissions that the firm would discharge in the absence of government policy. Determine the socially efficient level of emissions. Calculate the total costs to society for both a and b and draw a diagram illustrating these costs.
