The picture below shows the LRAC (long-run average cost) curve for a particular firm. Based on the picture below complete the sentences correctly! The portion of the LRAC curve, where it is downward- sloping from output levels Q1 to Q2 to Q3, illustrates the case of . In other words, as the quantity of output goes up, the cost per unit goes down. The portion of the LRAC curve, i.e. the flat portion of the curve around Q3, is the situation that allowing all inputs to expand does not change the average cost of production. We call this . The portion of the LRAC curve, running from output level Q4 to Q5, shows a situation where, as the level of output and the scale rises, average costs rise as well. We call this situation . Low-cost firms will produce an output level of , so that they can compete effectively. Firms producing less than or more than would face higher average costs and will be unable to compete.
