Answer:
The cost of production is marginal. Fixed and variable costs included. With regard to fixed costs, this is only calculated at the marginal cost of production is to be expanded. In contrast, marginal costs always include variable costs.
Explanation:
THE IMPORTANCE OF MARGINAL COST:
In economics, marginal costs are important as they help companies to maximize profits. When marginal costs are equal to marginal income, we have so-called profit maximization. In this respect, the cost of producing a further product is exactly the same as the sales of the company. That is, the company does not make money at that point anymore.
As seen from the below marginal costs curve, marginal costs begin to decrease as the company benefits from scale savings. Marginal costs can however increase with businesses declining in productivity and suffering from scale disadvantages. Costs are increasing and they ultimately receive marginal income.
It could be because the company becomes too big and inefficient, or because the management problem gets less productive and demotivated. Whatever the reason, companies may have to face up to rising costs and stop production if their income is identical to the marginal price.
