a)
To compute: The labor productivity under each system.
Introduction: Labor productivity is the measure of productivity of a worker during a period of time. It the ratio of total output to the total productivity hours.
a)
Answer to Problem 4P
Explanation of Solution
Given information:
Prior to buying new equipment:
After buying new equipment:
After buying new equipment, one worker is transferred to another department, equipment cost is increased by $10/hour and output increased by four carts/hour.
Formula:
Calculation of Labor productivity:
Prior to buying new equipment:
Labor productivity prior to buying new equipment is calculated by dividing number of carts of 80 with the number of workers 5 which yields 16 carts/worker/hour
After buying new equipment:
Labor productivity after buying new equipment is calculated by dividing number of carts of 84 with the number of workers 4which yields 21 carts/worker/hour.
Hence, labor productivity before buying new equipment is 16 carts/worker/hour and after buying new equipment is 21 carts/worker/hour.
b)
To compute: The multifactor productivity.
Introduction: Multifactor productivity is also referred as total factor productivity. It is the measure of economic performance by comparing the amount of goods and services produced to the total input used to produce the output.
b)
Answer to Problem 4P
Explanation of Solution
Given information:
Prior to buying new equipment:
After buying new equipment:
After buying new equipment, one worker is transferred to another department, equipment cost is increased by $10/hour and output increased by four carts/hour.
Formula:
Calculation of Multifactor productivity:
Prior to buying new equipment:
Labor cost is calculated by multiplying number of workers (5) with 10/ hours which gives 50/hour.
Multifactor productivity is calculated by dividing output of 80 carts with the total cost of $90 ($50+$40) which yields 0.89 carts/dollar.
After buying new equipment:
Labor cost is calculated by multiplying number of workers (4) with 10/ hours which gives 40/hour.
Multifactor productivity is calculated by dividing output of 84 carts with the total cost of $90 ($40+$50) which yields 0.93 carts/dollar.
Hence, multifactor productivity prior to buying new equipment is 0.89 carts/dollar and after buying new equipment is 0.93 carts/dollar.
c)
To determine: The changes in productivity and comment the best one.
Introduction: Productivity is the measure of performance of a person, machine or an organization. It is computed by dividing the average output per period by the total cost incurred or resources used in the process.
c)
Answer to Problem 4P
Explanation of Solution
Given information:
Prior to buying new equipment:
After buying new equipment:
After buying new equipment, one worker is transferred to another department, equipment cost is increased by $10/hour and output increased by four carts/hour.
Formula:
Labor productivity growth:
The labor productivity growth is calculated by dividing the difference of 21 and 16 with 16 which gives 31.25%
Multifactor productivity growth:
Multifactor productivity growth is calculated by dividing the difference of 0.93 and 0.89 with 0.89 which gives 4.49%.
Hence, labor productivity growth is 31.25% and multifactor productivity growth is 4.49%.

- A Company that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labor content of the jobs needed to produce the shopping carts. Prior to buying the new equipment, the company used 6 workers, who produced an average of 78 carts per hour. Workers receive $10 per hour, and machine coast was $36 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $13 per hour while output increased by four carts per hour.a) Compute the multifactor productivity (MFP) (labor plus equipment) under the Prior to buying the new equipment.

Because the company produces other items that share resources used to make the dishwashers, the stamping machine is available only 30 minutes per hour, on average. The motor installation production line has 60 minutes available each hour. There are two lines for wiring, so the time availability is 90 minutes per hour.

- Charles Lackey operates a bakery in Idaho Falls, Idaho. Because of its excellent product and excellent location, demand has increased by 5555% in the last year. On far too many occasions, customers have not been able to purchase the bread of their choice. Because of the size of the store, no new ovens can be added. At a staff meeting, one employee suggested ways to load the ovens differently so that more loaves of bread can be baked at one time. This new process will require that the ovens be loaded by hand, requiring additional manpower. This is the only production change that will be made in order to meet the increased demand. The bakery currently makes 1,800 loaves per month. Employees are paid $8 per hour. In addition to the labor cost, Charles also has a constant utility cost per month of $800 and a per loaf ingredient cost of $0.35 Current multifactor productivity for 640 work hours per month =0.27loaves/dollar (round your response to three decimal places).arrow_forwardCharles Lackey operates a bakery in Idaho Falls, Idaho.
