Question

Quizplus · Accepted Answer

Labor is not fixed as it can vary in terms of quantity and quality. The available workforce can increase or decrease depending on factors such as immigration, population growth, and education/training programs. Additionally, the skills and productivity levels of the workforce can also change. The other factors of production (technology, entrepreneurship, land, and money) may be variable to some extent, but they are generally considered to be fixed in the short run.
