In the period that can change the size and quantity of all kinds of inputs as required. Therefore, Inputs used in the production of a single type is a variable factor. In the long term under the rule of the rule.
Production in a period that can vary in size and quantities of inputs of any kind is needed, so the inputs used in the production of one kind of factor variability in production long under the rule of law results from.
The production period of time can change the size and quantity of inputs of all kinds according to need. So inputs used in the production of a single species. The variable. The long-run under the rule of law benefit from.
