Question

In economics, ________ is a period where some factor inputs are fixed, while the others are variable.

• A. long run
• B. short run
• C. very long period
• D. none of the above

Answer 1

The correct option is B short run

The short run, as economists use the phrase, is characterized by at least one fixed factor of production so the proportion of inputs can be changed, the law of variable proportion will only operate in the short run. It is in the long run all factors are variable as producers have enough time to organize all factor inputs in the appropriate proportions to achieve the minimum efficient scale.
