In the long run all factors of production are

In the long run, all factors of production are considered to be variable. This means that all inputs used in the production process can be adjusted or changed to meet the needs of the business. This is in contrast to the short run where at least one input is considered fixed, usually capital or land. In the long run, a business can change the amount of labor, capital, and land that it uses to produce its goods or services, and can even change its production process altogether. Therefore, the long run is a period of time during which a business can make all necessary adjustments to its inputs and production process, and all factors of production are variable.
