Achair manufacturer hires its assembly-line labor for $30 an hour and calculates that the rental cost of its machinery is $15per hour. suppose that a chair can be produced using 4 hours of labor or machinery in any combination. if the firm iscurrently using 3 hours of labor for each hour of machine time, is it minimizing its costs of production? if so, why? if not, how can it improve the situation? graphically illustrate the isoquant and the two isocost lines for the current combinationof labor and capital and for the optimal combination of labor and capital

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.

Miko willingly admits that she is not an accountant by training. she is concerned that her balance sheet might not be correct. she has provided you with the following additional information. 1. the boat actually belongs to miko, not to skysong, inc.. however, because she thinks she might take customers out on the boat occasionally, she decided to list it as an asset of the company. to be consistent, she also listed as a liability of the corporation her personal loan that she took out at the bank to buy the boat. 2. the inventory was originally purchased for $27,500, but due to a surge in demand miko now thinks she could sell it for $39,600. she thought it would be best to record it at $39,600. 3. included in the accounts receivable balance is $11,000 that miko loaned to her brother 5 years ago. miko included this in the receivables of skysong, inc. so she wouldn’t forget that her brother owes her money. (b) provide a corrected balance sheet for skysong, inc.. (hint: to get the balance sheet to balance, adjust stockholders’ equity.) (list assets in order of liquidity.)

Consider the labor market for computer programmers. during the late 1990s, the value of the marginal product of all computer programmers increased dramatically. holding all else equal, what effect did this process have on the labor market for computer programmers? the equilibrium wagea. increased, and the equilibrium quantity of labor decreased. b. decreased, and the equilibrium quantity of labor increased. c. increased, and the equilibrium quantity of labor increased. d. decreased, and the equilibrium quantity of labor decreased.
