Assume that Amazon sells the MacBook Pro, a computer produced by Apple, for a retail price of $1,500. Amazon arranges its operations such that customers receive products directly from Apple Stores rather than Amazon. Customers purchase from Amazon using credit cards, and Amazon forwards cash to Apple equal to the retail price minus a $150 commission that Amazon keeps. In this arrangement, how much revenue will Amazon recognize for the sale of one MacBook Pro?

4. suppose that pollution in a neighborhood comes from two factories, with marginal benefit curves given by mb1 = 12 – p1 and mb2 = 8 – p2. the level of pollution in the neighborhood is given by p = p1 + p2. the government wants to limit pollution by instituting a pollution-rights market. the government’s desired level of p is 10, so it prints 10 pollution rights and offers them for sale to the firms.a)find the equilibrium selling price of a pollution right, as well as the allocation of rights (and hence pollution levels) across the two factories. b)repeat part (a) for the case where the government’s desired level of pollution equals 14. c)comment on the usefulness of a pollution rights market in achieving efficient levels of pollution abatement.
