Short-Run Average Cost (SAC) and Long-Run Average Cost (LAC) Curve

In this article we will discuss about the relation between the short-run and long-run cost curves. In the long run all factors are variable. Therefore, the producer can operate without facing the constraints of the fixed factors. The long-run cost (LAC) is not more than the short-run cost (SAC) because the unconstrained minimum average cost at any output cannot be [...]
