Among them, marginal revenue (MR) refers to the extra revenue per unit of sales, while marginal cost (MC) refers to the extra cost per unit of output. When MR equals MC, enterprises will stop adjusting output, because increasing or decreasing output at this time will not bring more profits.
This principle applies not only to enterprises, but also to other types of economies, such as non-profit organizations, and how to optimize their resource utilization according to their costs and benefits.
In a word, MR=MC is a very important concept in economics, which can help enterprises determine the optimal output and maximize profits.
