Answer: True
Step-by-step explanation:
Marginal benefit is the maximum amount that a consumer will be willing to pay for an extra product. It should be known that as consumption rises, the marginal benefit starts reducing.
The marginal cost is the extra cost that a producer incurs when an extra unit of a product is made. Economic decisions made by economic agents are typically based on marginal as it'll be possible to know the impact of an extra decision made on a variable.
Therefore, it is better to evaluate economic decisions at the marginal, where the decision has to be made as long as its marginal benefit exceeds its marginal cost, if not equal to its marginal cost.
