Short Answers  

 

1. Define isoquant.  What is measured on the axes of a diagram with isoquants?  What is the relationship between the isoquant map and the production function?

 

2. Isoquants are downward-sloping, non-intersecting, convex curves.  Explain the basis for each of these characteristics.

 

3. For a particular combination of capital and labor we know that the marginal product of capital is 6 units of output and that the marginal rate of technical substitution is 3 units of capital per unit of labor.  What is the marginal product of labor?

 

4. If a firm’s isoquants were straight lines, what would that imply about the two inputs?  Is this realistic – give an example of why or why not?

 

5. If a firm’s isoquants were L-shaped, what would that imply about the two inputs?  Is this realistic – give an example of why or why not?
