Q4 [10 marks]. Suppose the market consists of two firms, both of which produce emissions of pollutants during their production process. The firms face the following marginal costs of abating emissions: MC1= 30 + 5A1, MC2= 42 + 3A2. Research suggests that the marginal benefit of abating emissions is MB = 88.5 4.5A, where A = A1+A2. A is the quantity abated in millions of tonnes, and the benefit and costs are given in /tonne. a) What is the socially efficient level of emissions abatement? [5 marks] b) What should the level of emissions abated by each firm be? [3 marks] c) What should the emission fee be to ensure that the socially optimal level of emissions abatement is reached?
