What is the primary effect of achieving allocative efficiency in a market concerning consumer surplus?

Allocative efficiency occurs in a market when resources are distributed in a way that maximizes the total benefit to society. This means that goods and services are produced and consumed at levels where the price reflects the true value to consumers. When allocative efficiency is achieved, consumer surplus—the difference between what consumers are willing to pay and what they actually pay—increases. For example, if a bakery sells bread for $2, but consumers would be willing to pay up to $3 for it, the $1 difference represents consumer surplus. Therefore, when a market reaches allocative efficiency, more people can buy bread at a fair price, leading to higher overall satisfaction and welfare.
