Final answer:
The equality between marginal benefit and marginal costs does indeed result in the maximization of market efficiencies, as it balances costs and benefits to society, which is particularly true in a perfectly competitive market.
Step-by-step explanation:
Under marginal analysis, the statement that equality between marginal benefit and marginal costs will result in the maximization of market efficiencies is generally accepted as correct. Marginal benefit is what the consumer is willing to pay, and it reflects the perceived value of the good or service.
Marginal cost represents the expense of producing one additional unit. If the price (P) is greater than the marginal cost (MC), society stands to gain more from producing additional goods, as the benefits outstrip the costs. Conversely, if P is less than MC, then the costs to society exceed the benefits.
The ideal economic condition is achieved when P equals MC, where the costs and benefits to society are in balance, a situation typically found in a perfectly competitive market.
Thus, marginal analysis guides resource allocation for optimal efficiency within an economy, suggesting that if marginal costs exceed marginal benefits, resources could be reallocated for better use.
