Problem 08-14 (Algo)
You are the manager of a small pharmaceutical company that received a patent on a new drug three years ago. Despite strong sales ($150 million last year) and a low marginal cost of producing the product ($0.50 per pill), your company has yet to show a profit from selling the drug. This is, in part, due to the fact that the company spent $1.7 billion developing the drug and obtaining FDA approval. An economist has estimated that, at the current price of $1.50 per pill, the own price elasticity of demand for the drug is -2.
Based on this information, what can you do to boost profits?

[removed] Reduce price.
[removed] Keep price the same.
[removed] Raise price.

You are the general manager of a firm that manufactures personal computers. Due to a soft economy, demand for PCs has dropped 50 percent from the previous year. The sales manager of your company has identified only one potential client, who has received several quotes for 10,000 new PCs. According to the sales manager, the client is willing to pay $800 each for 10,000 new PCs. Your production line is currently idle, so you can easily produce the 10,000 units. The accounting department has provided you with the following information about the unit (or average) cost of producing three potential quantities of PCs:

10,000 PCs 15,000 PCs 20,000 PCs
 Materials (PC components) $600 $600 $600
 Depreciation 300 225 150
 Labor 150 150 150
 Total unit cost $1,050 $975 $900

Based on this information, should you accept the offer to produce 10,000 PCs at $800 each?

[removed] Yes.
[removed] No.
[removed] You should be just indifferent between accepting and declining.
