Arvonalentumiskulu, also known as marginal cost, refers to the additional cost incurred by a firm when it produces one more unit of a good or service. It is a key concept in economics and is used to determine the efficiency of production and pricing strategies. Marginal cost is calculated by subtracting the cost of producing the previous unit from the total cost of producing the current unit. This cost includes both fixed and variable costs, but it is primarily influenced by variable costs, as fixed costs are spread over a larger number of units.

Understanding marginal cost is crucial for firms to make informed decisions about production levels and pricing. When marginal cost is less than the price of the good or service, a firm can increase production to maximize profits. Conversely, if marginal cost exceeds the price, the firm may need to reduce production or adjust its pricing strategy to remain profitable. Marginal cost also plays a significant role in market equilibrium, as it helps determine the quantity supplied at different price levels.

In a perfectly competitive market, marginal cost is equal to the price at the profit-maximizing output level. This is because in such markets, firms cannot influence the price of their products. In contrast, in monopolistic or oligopolistic markets, firms may set prices above marginal cost to maximize profits, leading to a deadweight loss in efficiency. The concept of marginal cost is fundamental to various economic theories and models, including supply and demand analysis, cost-benefit analysis, and production theory.
