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?
A firm is considering the installation of an automatic data processing unit to handle some of its accounting operations. Machines for that purpose may be purchased for 20,000 or may beleased for 8,000 for the first year and 1,000 less every year now and then until the end of the fourth year. If money is worth 15%, is it advisable to rent or buy a machine?

- Develop a production plan and calculate the annual cost for a firm whose demand forecast is fall, 10,000; winter, 8,000; spring, 7,000; summer, 12,000. Inventory at the beginning of fall is 500 units. At the beginning of fall, you currently 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 stock-outs at the end of those quarters. Overtime is not available during the fall. Relevant costs are hiring, $100 for each temp; layoff, $200 for each worker laid off; inventory holding, $5 per unit-quarter; backorder, $10 per unit; straight time, $5 per hour; over time, $8 per hour. Assume that productivity is 0.5 units per worker hour, with eight hours per day and 60 days per season.

Fixed costs are $14,000. Current volume is 30,000 units. The firm can substantially improve the productquality by adding a new piece of equipment at an additional fixedcost of $6,000. Variable cost would increase to $.60, but volumeshould jump to 50,000 units due to a higher-quality product.Should the company buy the new equipment?arrow_forward

- Suppose that an aircraft manufacturer desires to make a preliminary estimate of the cost of building a 600-MW fossil-fuel plant for the assembly of its new longdistance aircraft. It is known that a 200-MW plant cost $100 million 20 years ago when the approximate cost index was 400, and that cost index is now 1,200. The cost-capacity factor for a fossil-fuel power plant is 0.79. Estimate the cost using power sizing method.arrow_forwardFirms will increase production when planned investment is less than (actual) total investment.” Is this statement true, false, or uncertain? Explain your answerarrow_forwardA company has the following demand data for the last three years of sales for their popular product B. 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.
