4. Consider Apple Computers back in 1988 and 1989. The DRAM chips were purchased for $38. Before they are used, a new virus spreads worldwide and shuts down production. With limited supply, the DRAM chips are now selling for $68.
All the other components that go into a Macintosh computer are worth $1000.

Choice 2 of 3:You should increase production and sales.
Choice 3 of 3:You should decrease production and sales.

Choice 1 of 2:True
Choice 2 of 2:False
Modeling Costs and Competitive Supply
1. A Cobb-Douglas production function for a company that buys its inputs in competitive markets leads to a linear cost curve.
Choice 1 of 2:True
Choice 2 of 2:False
Save Answer
2. A firm can use the information in the marginal cost curve to determine if it should operate or not.
