Essential Knowledge: PRD-1.A.9
In the long run, firms can adjust all their inputs, and as a result, all costs become variable.
Essential Knowledge: PRD-1.A.10
The relationship between inputs and outputs in the long run is described by the scale of production—increasing, decreasing, or constant returns to scale.
Essential Knowledge: PRD-1.A.11
The long-run average total cost is characterized by economies of scale, diseconomies of scale, or constant returns to scale (efficient scale).
Essential Knowledge: PRD-1.A.12
The minimum efficient scale plays a role in determining the concentration of firms in a market and the market structure.
