A monopolist has four distinct groups of customers: group A has an elasticity of demand of 0.2, group B has an elasticity of demand of 0.8, group C has an elasticity of demand of 1.0, and group D has an elasticity of demand of 2.0. The group paying the lowest price for the product will be group:

Emily bought 200 shares of abc co. stock for $29.00 per share on 60% margin. assume she holds the stock for one year and that her interest costs will be $80 over the holding period. ignoring commissions, what is her percentage return (loss) on invested capital if the stock price went down 10%?

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.
