Consider two rubber companies, Firestone and Goodyear. Both companies create air pollution when they produce rubber. The air pollution can be reduced by the firm, but the abatement comes at a cost. Specifically,MACF = 1200 – 6eF, where eF = tons of emissions produced by FirestoneMACG = 400 – 2eG, where eG = tons of emissions produced by GoodyearA) the government wants to use an effluent tax to reduce emissions to 200 tons. What tax level reduces emissions in the most cost-effective way for the firms and what is the optimal number of emissions for each firm?
