The Pillercat Corporation The Pillercat Corporation is a highly decentralized company. Each division manager has full authority for sourcing decisions and selling decisions. The Machining Division of Pillercat has been the major supplier of the 2,000 crankshafts that the Tractor Division needs each year. The Tractor Division, however, has just announced that it plans to purchase all its crankshafts in the forthcoming year from two external suppliers at Rs 2,000 per crankshaft. 

The Machining Division of Pillercat recently increased its selling price for the forthcoming year to Rs 2,200 per unit (from Rs 2,000 per unit in the current year). Juan Gomez, manager of the Machining Division, feels that the 10% price increase is justified. It results from a higher depreciation charge on some new specialized equipment used to manufacture crankshafts and an increase in labor costs. Gomez wants the president of Pillercat Corporation to force the Tractor Division to buy all its crankshafts from the Machining Division at the price of Rs 2,200. The following table summarizes the key data.
