It also stimulates production of IGF-1. GH is used as a prescription drug in medicine to treat children's growth disorders and adult growth hormone deficiency. In the United States, it is only available legally from pharmacies, by prescription from a doctor.
Marginal cost is the change in total cost when another unit is produced; average cost is the total cost divided by the number of goods produced. Distinguish between marginal and average costs. The marginal cost is the cost of producing one more unit of a good.
If marginal cost is greater than average total cost, then average total cost is rising. The vertical distance between the short-run average total and average variable cost curves is equal to marginal cost.he level of output at which the average product of a variable input is at a maximum corresponds to the level of output where short-run average total cost is at a minimum. All costs are variable costs in the long run. The long-run total cost curve is derived from the firm's expansion path.
