Long-run cost relationships The following graph shows the short-run average total cost curves and the long-run average cost curve for a publishing firm. The five marked quantities indicate points of tangency between each short-run average total cost curve (SRATC) and the long-run average cost curve (LRAC); for example, Q₁ marks the point of tangency between SRATC₁ and LRAC. The orange point on SRATC3 indicates the firm's current output level in the short run (Q3).
