6) Felicien grows mirlitons (that's Cajun for Chayote squash) in

Question : 6) Felicien grows mirlitons (that's Cajun for Chayote squash) in : 1977127

6) Felicien grows mirlitons (that's Cajun for Chayote squash) in his 100 by 100 foot garden. He then sells the crop at the local farmers' market. Two summers ago, he was able to produce and sell 1200 pounds of mirlitons. Last summer, he tried a new fertilizer that promised a 50% increase in yield. He harvested 1900 pounds. Did the fertilizer live up to its promise?

7) The Dulac Box plant produces wooden packing boxes to be used in the local seafood industry. Current operations allow the company to make 500 boxes per day, in two 8-hour shifts (250 boxes per shift). The company has introduced some moderate changes in equipment, and conducted appropriate job training, so that production levels have risen to 300 boxes per shift.  Labor costs average $10 per hour for each of the 5 full-time workers on each shift. Capital costs were previously $3,000 per day, and rose to $3,200 per day with the equipment modifications.  Energy costs were unchanged by the modifications, at $400 per day. What is the firm's multifactor productivity before and after the changes?

8) Gibson Products produces cast bronze valves for use in offshore oil platforms. Currently, Gibson produces 1600 valves per day. The 20 workers at Gibson work from 7 a.m. until 4 p.m., with 30 minutes off for lunch and a 15 minute break during the morning work session and another at the afternoon work session. Gibson is in a competitive industry, and needs to increase productivity to stay competitive. They feel that a 20 percent increase is needed.

Gibson's management believes that the 20 percent increase will not be possible without a change in working conditions, so they change work hours. The new schedule calls on workers to work from 7:30 a.m. until 4:30 p.m., during which workers can take one hour off at any time of their choosing. Obviously, the number of paid hours is the same as before, but production increases, perhaps because workers are given a bit more control over their workday. After this change, valve production increased to 1800 units per day.

a.Calculate labor productivity for the initial situation

b.Calculate labor productivity for the hypothetical 20 percent increase

c.What is the productivity after the change in work rules?

d.Write a short paragraph analyzing these results.

9) A local university is considering changes to its class structure in an effort to increase professor productivity.  The old schedule had each professor teaching 5 classes per week, with each class meeting an hour per day on Monday, Wednesday, and Friday.  Each class contained 20 students.  The new schedule has each professor teaching only 3 classes, but each class meets daily for an hour.  New classes contain 50 students.

a.Calculate the labor productivity for the initial situation (students/hour).

b.Calculate the labor productivity for the schedule change (students/hour).

c.Are there any ethical considerations that should be accounted for?

d.Suppose that each teacher also is required to have 2 hours of Office Hours each day he/she taught class.  Is the schedule change a productivity increase?

10) A grocery chain is considering the installation of a set of 4 self-checkout lanes.  The new self-checkout lane setup will replace 2 old cashier lanes that were staffed by a cashier and bagger on each lane.  One cashier mans all 4 self-checkouts (answering questions, checking for un-scanned items, taking coupons, etc).  Checkout on the new lanes takes 2 minutes (customers bag their own orders) while checkout with the old lanes took only 45 seconds. In addition the electricity costs for both setups are $.05 per checkout while bagging (material) costs are $.1 per checkout with the old system and $.15 for the new system. The new lanes also require $100 in capital costs.  Assume that the lanes are always in use for 8 hours per day (1 shift) and that a worker makes $10/hour.

a.How many checkouts did the old system provide in a shift?

b.How many checkouts does the new system provide?

c.What is the multifactor productivity for each system?
