The measure of the advantage of producing one additional unit is called?

• A. Capitalism
• B. Economic decision making
• C. Marginal benefit
• D. Needs

Answer: (C)

Marginal benefit is the extra benefit you get from producing one more unit. It’s about the value the next unit adds to the decision maker, whether a firm or a consumer. In practice, this idea sits at the heart of optimization: you compare the additional benefit of one more unit to the additional cost of producing it. If the extra benefit exceeds the extra cost, producing another unit adds value; if not, you stop at the current level of output. For example, if making one more widget costs $5 and it can be sold for $8, that extra unit provides a $3 marginal benefit, supporting production of that unit. The other terms describe broader concepts—a economic system, the decision-making process, or basic needs—not the specific incremental measure of benefit from one more unit.
