A rational choice is made by comparing marginal benefit and marginal cost
The marginal cost in economics is the change in total cost that occurs when the amount produced is increased, or the cost of producing more quantity.
The law of declining marginal utility asserts in economics that the marginal usefulness of a good or service decreases as an individual consumes more of it. Consuming incremental amounts of a good provides less and less satisfaction to economic agents.
Marginal cost is an important concept in economic theory because a corporation seeking to maximize profits will produce until marginal cost (MC) equals marginal revenue (MR) (MR). After then, the cost of creating an additional item will outweigh the money generated.
