Harootunian Corporation uses a job-order costing system with a single plantwide predetermined overhead rate based on machine-hours. The company based its predetermined overhead rate for the current year on the following data:

Total machine-hours80,000Total fixed manufacturing overhead cost$312,000Variable manufacturing overhead per machine-hour$2.10

Recently, Job T629 was completed with the following characteristics:

Number of units in the job50Total machine-hours200

The predetermined overhead rate is closest to:

a. $8.10 per machine-hour
b. $2.10 per machine-hour
c. $3.90 per machine-hour
d. $6.00 per machine-hour

The risk-free rate is 7% and the expected rate of return on the market portfolio is 11%. a. calculate the required rate of return on a security with a beta of 1.92. (do not round intermediate calculations. enter your answer as a percent rounded to 2 decimal places.) b. if the security is expected to return 15%, is it overpriced or underpriced?

The market for corn in country a is highly competitive. at the current market price of $5/bushel there is a shortage of 100,000 bushels of corn in this country. media reports claim that the price of corn will rise drastically in the near future. according to these reports, the neighboring country b had witnessed a similar situation recently. at the same price, the shortage in country b was also 100,000 bushels and eventually the equilibrium price in b went up to $10/bushel. both countries are known to have equal number of corn producers and the market supply of corn is identical at all prices. this, combined with the fact that consumers in the two countries also have similar tastes and preferences, led the media to conclude that the price of corn in country a would soon be as high as $10/bushel. the new equilibrium price turns out to be below $10/bushel, what inferences can be drawn?

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.
