When variable costs rise faster than output.
159

163
Describe the relationship illustrated by a production function.
Production is the transformation of inputs (land, labour, capital) into goods and services. The actual relationship between an input and output is displayed on a production function. Illustrates the maximum output that can be achieved with a given level of an input, assuming all other inputs are fixed.
164
How do fixed and variable inputs differ?
Fixed inputs do not vary with the level of output. Variable inputs do.
165
In the long run, what happens to fixed inputs?
No fixed inputs in the long run.
| Quantity of all inputs can potentially be varied.
166
What is the law of diminishing returns?
Law states that each successive unit of output tends to result in smaller increases in output. Occurs in all production systems as the output becomes constrained by the other inputs.
167

Price x TPP
168
Marginal revenue is equal to what?
