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.
The short-run marginal cost (MC) curve will at first decline and then will go up at some point, and will intersect the average total cost and average variable cost curves at their minimum points.he average total cost (ATC) curve initially will decline as fixed costs are spread over a larger number of units, but will go up as marginal costs increase due to the law of diminishing returns. The graph below illustrates the shapes of these curves.Figure 3.8: Cost Curves.
