You are watching: When marginal cost is greater than average cost, average cost is
There space several methods to measure the prices of production, and some of these costsare connected in exciting ways.For example, average cost (AC), also called average complete cost, is the complete cost divided by amount produced; marginal cost (MC) is the incremental cost of the last unit produced. Here"s exactly how average costand marginal expense are related:
The production procedures of many businesses eventually an outcome in diminishing marginal product that labor and also diminishing marginal product the capital, which way that many businesses reach a allude of production where each additional unit of labor or resources isn"t as beneficial as the one that come before.
Once diminishing marginal commodities isreached, the marginal expense of producing each added unit will certainly be higher than the marginal cost of the vault unit. In various other words, the marginal expense curve for many production processes will ultimately slope upward, as displayed here.
Because typical cost has fixed cost but marginal price does not, that is normally the instance that average cost is higher than marginal price at small quantities that production.
This means that average price generally take away on a U-type shape, because average cost will it is in decreasing in quantity as lengthy as marginal expense is much less than average cost butthen will start enhancing in quantity when marginal expense becomes higher than median cost.
This relationship likewise implies that typical cost and also marginal expense intersect in ~ the minimum the the average price curve. This is because average cost and also marginal price come together when average price has done every its decreasing however hasn"t started boosting yet.
Because marginal cost for a natural monopoly doesn"t increase in quantity as it at some point does for most firms, average price takes top top a different trajectory for herbal monopolies than for various other firms.
Specifically, the addressed costs involved with a natural monopoly imply that average price is better than marginal expense for small quantities the production. The reality that marginal cost for a natural monopoly doesn"t boost in quantity means that average price will be higher than marginal price at all manufacturing quantities.

This way that, quite than gift U-shaped, average expense for a natural monopoly is constantly declining in quantity, as shown here.
