Park uses a perpetual inventory system. Determine the cost assigned to ending inventory and to cost of goods sold using (a) specific identification, (b) weighted average, (c) FIFO, and (d) LIFO. (Round per unit costs to
three decimals, but inventory balances to the dollar.) For specific identification, ending inventory consists of
225 units, where 90 are from the March 30 purchase, 80 are from the March 20 purchase, and 55 are from
beginning inventory.

Uppose the book-printing industry is competitive and begins in a long-run equilibrium. then hi-tech printing company invents a new process that sharply reduces the cost of printing books. suppose hi-tech's patent prevents other firms from using the new technology. which of the following statements are true about what happens in the short run? check all that apply. hi-tech's average-total-cost curve shifts downward. hi-tech's profits increase. the price of books remains the same. hi-tech's marginal-cost curve remains the same.

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.

Adistinguishing feature of ecological economics is the concept of cost-benefit analysis steady-state economies that, like natural systems, neither grow nor shrink environmental damage and also environmental benefits are external greenwashing to increase public acceptance of products the only healthy economy is one that is growing
