Consider the diagram at the right of SRATC and LRAC curves. The SRATC curve is drawn for a given plant size. Part 2 a. Given a plant size associated with SRATC, the level of output that minimizes short-run average costs is Upper Q 2 Upper Q 0 Upper Q 1 . Unit costs in the short run at this level of output are c 1 c 3 c 0 c 2
