The law of demand is a principle that states that there is an inverse relationship between price and quantity demanded. Multiply both sides of this equation by price (P): (P- MC) = 0.5P, or 0.5P = MC, which yields: P = 2MC. Does marginal revenue actually refer to marginal revenue per time unit? When marginal revenue is higher than a firm's marginal cost, then it is making money. When marginal revenue equals marginal cost, it means that the additional revenue generated from selling 1 more unit (of whatever it is you're selling) exactly offsets the additional cost of producing that 1 unit. The Economics of Food and Agriculture Markets. Email us at[emailprotected]. If MR>MC then you will always increase profits as the revenue gained from that next unit exceeds the cost for that unit. To derive MC the first derivative of the total cost function is taken.
