Consider two firms with the following marginal abatement cost (MAC) functions: MAC1 = 22-2E1 MAC2 = 10-E2 Moreover, assume that the marginal external damages (MED) from the aggregate emissions of both firms (EA = E1 + Ez) is given by MED = 0.5EA. - Suppose that the government institutes a cap and trade (i.e., tradable permits) policy in order to achieve the socially efficient level of aggregate emissions (EA), meaning that the government sets the cap (or total amount of permits) equal to the socially efficient level of aggregate emissions EA*. If firm 2 is initially grandfathered 2 permits, then how many permits will it buy? Please round your final answer to two decimal places if necessary
