Applied Problems from Chapters 8 and 9 The application of material is the true test of knowledge. With the help of the concepts and theories learned from Chapter 8 and 9, this paper will answer the second applied problem from Chapter 8 and the second and fourth applied problems from Chapter 9. Chapter 8 At a management luncheon, two managers were overheard arguing about the following statement: “A manager should never hire another worker if the new person causes diminishing returns.” Is this statement correct?

The scenario presented describes a question managers must face every day. It is not wise hire another workers solely due to them causing diminishing returns. According to the Law of Diminishing Marginal Product, as long as the marginal product does not become negative, it would be wise that a manager hire beyond the initial diminishing number (Thomas and Maurice, 2011). For example, if 1200 units need to be produced and the 11th person hired causes the returns to diminish, then it would be advantageous to the manager to hire enough employees to satisfy the output without causing the marginal product to drop below zero.

Chapter 9 2. The Largo Publishing House uses 400 printers and 200 printing presses to produce books. A printer’s wage rate is \$20, and the price of the printing press is \$5,000. The last printer added 20 books to total output, while the last press added 1,000 books to total output. Is the publishing house making the optimal input choice? Why or why not? At the current input, Largo Publishing House is not making the optimal choice on input amounts. With the current inputs, they are underestimating the printers employed. Fifty printers could do the job of 1 printing press machine with a savings of \$4,000.

2a. If not, how should the manager of Largo Publishing House adjust input usage? To maximize output on a fixed budget, Largo Publishing House should transfer some of the money spent on printing presses to the printers. At 1650 printers and 195 printing presses, combined they could produce 228,000 books for their limited budget. On the other hand, at 1900 printers and 190 printing presses, Largo Publishing could not only produce the same amount but also save \$20,000 in the process.

4. The MorTex Company assembles garments entirely by hand even though a textile machine exists that can assemble garments faster than a human can. Workers cost \$50 per day, and each additional laborer can produce 200 more units per day (i.e., Marginal product is constant and equal to 200). Installation of the first textile machine on the assembly line will increase output by 1,800 units daily. Currently the firm assembles 5,400 units per day.

4a. The financial analysis department of MorTex estimates that the price of a textile machine is \$600 per day. Can management reduce the cost of assembling 5,400 units per day purchasing a textile machine and using less labor?

No it would not be possible to reduce the cost of assembling 5,400 units per day by purchasing a textile machine at the current worker wage of \$50 per day. The cost of the total production would be \$5,400 at any point where the amount if textile machines increased and the amount of workers decreased. For example, if three textile machines were bought and the amount of workers was decreased to 72, although totally they would produce 9000 units, it would still cost \$5400.

4b. The Textile Workers of America is planning to strike for higher wages. Management predicts that if the strike is successful, the cost of labor will increase to \$100 per day. If the strike is successful, how would this affect the decision in part a to purchase a textile machine?

In part a, if more the amount of workers decreased and textile machines were purchased, MorTex would have been spending the same amount of money toward their production total. If the strike is successful and the workers’ wages increased from \$50 to 100, it would be in the best interest of MorTex to purchase 9 textile machines and layoff all of their workers. If they pursued this option, they could produce 16,200 units with the same \$5,400 they were already spending.

Such as whether it worth to bear higher risk to do Job C, and do we have confidence in making different types of books. If we are confident towards the job, sure we can overlook the risk and try to maximize the profit but doing Job C. However, none of us are very confident in doing the job because it requires different number of pages and different color paper to make the cover. Eventually we decide to go for Job A, as it is easy to do, and in the time repeating the job, the labor himself may become more familiar with the job and hence, rate of production may increase through out the production time. The potential profits can be greater than we consider the production is under linear rate.…

For computer paper for the next fiscal quarter, according to the information given by the superintendent, Mendel Paper Company will receive a profit of \$240,000.00. If 30,000 units are produced and sold at \$14.00 then the total sales will be \$420,000.00. However it costs the company \$6.00 to produce each unit. So, 30,000 units at \$6.00 a unit costs the company \$180,000.00. The total sales cost of \$420,000.00 minus the cost of labor of \$180,000.00 equals the profit of \$240,000.00. News came in however from the vice-president of purchasing that the company has firm orders for 35,000 cartons of computer paper. So, if the company continues to sell each unit of computer paper at \$14.00 then the total cost of sales is \$490,000.00. It still costs Mendel Paper Company \$7.00 to produce each unit, therefore costing the company \$245,000.00. Making the total profit of computer paper \$245,000.00.…

This scenario where adding more workers or employees results in a diminished productivity is a classic example of the principle of diminishing marginal returns to a variable input. The concept, as discussed by Thomas and Maurice on page 296 states that the law of diminishing marginal product is “the principle that as the number of units of the variable input increases other inputs held constant, a point will be reached beyond which the marginal product decreases. For example, I work in a pastry shop and we make cakes. I typically schedule three bakery employees to make 90 cup cakes in three hours. That averages 30 cupcakes per employee in that three-hour time span. Assuming the variable being the number of employees all else remaining constant. If I add a fourth, fifth, or sixth employee I should get 30 cup cakes produced for every additional employee I add. The concept: law of diminishing marginal product, theorizes that at some point this will not be so. When the fifth or sixth baker shows up something happens, I run out of oven space, utensils, equipment, space, etc. All the bakers can’t possibly make 30 cup cakes each at the same time and things slow down. It then starts to take…
