The difference results from the downward-sloping demand curve. To sell one additional unit, the monopolist generally must reduce the price, and that lower price applies to the units sold under the new pricing decision. Consequently, the extra income from the added unit is smaller than the price received for that unit.
Demand elasticity provides a way to assess how strongly revenue responds to pricing decisions. Because a monopolist must consider the price reduction needed to increase sales, elasticity helps connect changes in price with changes in quantity sold. This analysis supports more informed evaluation of alternative pricing choices and their revenue consequences.
A revenue schedule organizes prices, quantities, total revenue, and marginal revenue across possible sales levels. Comparing entries shows how additional sales affect income and where revenue changes as output expands. It gives analysts a systematic basis for examining pricing decisions rather than relying on a single price or quantity observation.
They first calculate total revenue for each sales level by combining the listed price and quantity. They then compare total revenue between adjacent quantities to determine the additional income associated with one more unit. Reading these measures together shows how expanded sales and required price changes shape the seller’s income.
Revenue measures alone do not determine the most profitable output because production costs must also be considered. Analysts compare the revenue consequences of alternative quantities with the costs of producing them. This combined assessment identifies the output level at which the relationship between income and production costs supports the greatest profit.
Revenue analysis connects a monopolist’s pricing and output choices with the resulting positions of consumers and producers. Examining total revenue, marginal revenue, demand conditions, and production costs helps explain the economic consequences of market power. These relationships provide a framework for studying how different decisions distribute effects between the seller and buyers.
