The article on Emission Taxes is talking about how the government sets an amount of taxes that companies pay for every unit of pollution that they produce. With this certain policy there is a couple of advantages, which are it makes businesses internalize negative externality costs, and can solve the problem of economic inefficiency by allowing firms to maximize profit and pollute at the most efficient level. This way there will be less pollution because companies will want to avoid the tax. When thinking about it that way I think that emission taxes would not be a bad idea, because there would be less pollution. The only problem with emission taxes is that the government would have to carefully measure how much to tax each company.
