In the long run (B.) inputs that were fixed in the short run(SR) become variable.
Resources are finite, and producers use one factor as the short-term variable (SR) while keeping all other factors constant. In SR, total output depends only on changes in the inputs of this variable. However, in the long run (LR), producers have many options, and in LR all inputs are alternatives to variable inputs. In LR, no factor of production is considered fixed.
Short-Term Frozen Inputs Remain Frozen: No inputs remain frozen in LR. All inputs are variable.
inputs that were temporarily variable are fixed. Only one input is considered variable in SR. However, LR considers all inputs to be variable, including inputs that are considered constant and inputs that are considered variable by SR.
Variable input is rarely used. The amount of output (Q) depends on the variable input. The change in output volume also depends on this variable input. Therefore, the production process requires variable inputs.
