Short Run Production Relationships         List and explain the 3 Short Run Production Relationships      Explain who in a business would care about them and how they might be used.

How does fixed cost affect marginal cost? Why is this relationship important?

In choosing a production technology, how will firms react if one input becomes relatively more expensive?

Average cost curves (except for avenge fixed cost) tend to be U-shaped, decreasing and then increasing. Marginal cost curves have the same shape, though this may be harder to see since most of the marginal cost curve is increasing. Why do you think that average and marginal cost curves have the same general shape?

A small company that shovels sidewalks and driveways has 100 homes signed up for its services this winter. It can use various combinations of capital and labor: intensive labor with hand shovels, less labor with snow blowers, and still less labor with a pickup truck that has a snowplow on front. To summarize, the method Choices are: Method 1: 50 units of labor, 10 units of capital Method 2: 20 units of labor, 40 units of capital Method 3: 10 units of labor, 70 units of capital If hiring labor for the winter costs $100/unit and a unit of capital costs 400, what is the best production method? What method should the company use if the cost of labor rises to $20/unit?
