You have been hired by Kia as manager for its Pakistan operations. Assume following is the short-run production function at their assembly plant outside Karachi:
Q = 10L2 – 0.5 L3 where L is variable input labor, Q is output of Cars assembled
a. At the end of the year it is expected that output will double with purchase ofnew equipment and machinery. The production function is estimated to be
Q = 60L.30K.70 where L is labor and K is capital.
Suppose initial L1 = 1 and K1 = 1. When inputs are in increased to L2 = 2 and K2 = 2,
do you observe increasing, decreasing or constant returns to scale?
b. Assume Kia Head Office is considering hiring more laborers either at their Gwadar plant or alternatively at the Karachi plant. What will be your advice if workers’ marginal product is 40 at wage of Rs=5/hour in Karachi and marginal product is 28 at wage of Rs=4/hour in Gawdar?
Develop a production plan and calculate the annual cost for a firm whose demand forecast is fall, 10,900; winter, 8,400; spring, 7,100; summer, 12,900. Inventory at the beginning of fall is 545 units. At the beginning of fall, you have 30 workers, but you plan to hire temporary workers at the beginning of summer and lay them off at the end of summer. In addition, you have negotiated with the union an option to use the regular workforce on overtime during winter or spring if overtime is necessary to prevent backorders at the end of those quarters. Overtime is not available during the fall. Relevant costs are hiring, $800 for each temp; layoff, $1,600 for each worker laid off; inventory holding, $5 per unit-quarter; backorder, $10 per unit; straight time, $25 per hour; overtime, $35 per hour. Assume that the productivity is 0.5 unit per worker hour, with eight hours per day and 60 days per season. In each quarter, produce to the full output of your regular workforce, even if that results…

- Box Electric makes electronic components and has estimated the following for a new design of one of its products. Fixed cost = $24,975 Material cost per unit = $0.17 Labor cost per unit = $0.12 Revenue per unit = $0.66 Note that fixed cost is incurred regardless of the amount produced. Per-unit material and labor cost together make up the variable cost per unit. Assuming that Box Electric sells all that it produces, profit is calculated by subtracting the fixed cost and total variable cost from total revenue. Construct an appropriate spreadsheet model to find the profit based on a given production level and use the spreadsheet model to answer these questions. (a) Construct a one-way data table with production volume as the column input and profit as the output. Breakeven occurs when profit goes from a negative to a positive value; that is, breakeven is when total revenue = the total cost, yielding a profit of zero. Vary production volume from 0 to 100,000 in increments of 10,000.…arrow_forwardDevelop a production plan and calculate the annual cost for a firm whose demand forecast is fall, 11,000; winter, 8,000; spring, 6,000; summer, 13,000.

There are currently 5 workers assigned to the production line, each capable of producing approximately 8 units per month. It is assumed that each month has the same number of production days. They can hire more workers at a hiring and training cost of $800 per worker. If they layoff any workers, the unemployment cost is $2,000 per worker. The product has a standard production cost (labor, material, and overhead) of $300 per unit. The extra cost to produce one unit on overtime is $50 and the maximum overtime is two units per month per worker. They can use inventory but it will cost them $25 per unit per month for any unit in inventory at the end of the month. Failure to meet market demand typically will imply the customer will buy from another supplier, and therefore cost the company $100 in profit. They currently have 0 units in inventory. a.
