Positive marginal utility occurs when the consumption of an additional item increases the total utility, while negative marginal utility occurs when the consumption of an additional item decreases the total utility. In other words, marginal utility is the utility of the marginal use. In this situation, increasing production volume causes marginal costs to go down. Because marginal analysis is only interested in the effect of the very next instance, it pays little attention to fixed start-up costs.
