Firms in a polluting industry can be classified in two groups: newer Örms with a cleaner technology that can abate pollution at a lower marginal cost M CLA L = (1/2) aL and older Örms with dirtier M CAH = aH , where ai is the level of abatement undertaken by firms of type i = L,H. The social marginal benefit of abating pollution from this particular industry is MBA = 120 - A, where A is the aggregate level of abatement in that industry: (a) To design an efficient emissions standard, the government needs to determine which is the efficient abatement allocation (aL; aH ). In order to do this, obtain a cost e§ective abatement allocation (aL;aH) that provides an aggregate abatement level A = a*L , a*H and then proceed to determine the efficient level A * (Hint: You should obtain that MCA = A/3).
