Aaron’s plan is to put $100 at the beginning of each month into a savings account which pays 4.5% interest, compounded monthly. As usual, interest is paid at the end of each month on money which has been in the account all month; in other words, the first deposit does earn interest during the first month. If he starts saving $100 per month when he is 25, how much will he have in the account when he turns 70? [Assume that he makes 12 deposits when he is 25, another 12 when he is 26, etc., but no more deposits once he is 70.]

Ajustification for job training programs is that they improve worker productivity. suppose that you are asked to evaluate whether more job training makes workers more productive. however, rather than having data on individual workers, you have access to data on manufacturing firms in ohio. in particu- lar, for each firm, you have information on hours of job training per worker (training) and number of nondefective items produced per worker hour (output). (i) carefully state the ceteris paribus thought experiment underlying this policy question. (ii) does it seem likely that a firm’s decision to train its workers will be independent of worker characteristics? what are some of those measurable and unmeasurable worker characteristics? (iii) name a factor other than worker characteristics that can affect worker productivity. (iv) if you find a positive correlation between output and training, would you have convincingly established that job training makes workers more productive? explain.

If jobs have been undercosted due to underallocation of manufacturing overhead, then cost of goods sold (cogs) is too low and which of the following corrections must be made? a. decrease cogs for double the amount of the underallocation b. increase cogs for double the amount of the underallocation c. decrease cogs for the amount of the underallocation d. increase cogs for the amount of the underallocation

(b) assuming that periodic inventory records are kept in units only, compute the inventory at april 30 using lifo and average-cost. (c) assuming that perpetual inventory records are kept in dollars, determine the inventory using (1) fifo and (2) lifo. (d) compute cost of goods sold assuming periodic inventory procedures and inventory priced at fifo.
