Suppose that a price-discriminating monopolist has segregated its market into two groups of buyers, the first group described by the demand and revenue data that you developed for question $5 .$ The demand and revenue data for the second group of buyers is shown in the accompanying table. Assume that $\mathrm{MC}$ is $\$ 13$ in both markets and $\mathrm{MC}=\mathrm{ATC}$ at all output levels. What price will the firm charge in each market? Based solely on these two prices, what can you conclude about the relative elasticities of demand in the two markets? What will be this monopolist's total economic profit?

Key Concepts

Marginal Cost

Marginal cost (MC) represents the additional cost incurred from producing one more unit of a good. For a profit-maximizing monopolist, setting production where marginal revenue equals marginal cost is crucial. When MC is constant across markets, it serves as a benchmark for determining the optimal price in each segment.

Elasticity of Demand

Elasticity of demand measures how sensitive the quantity demanded of a product is to changes in its price. In the context of price discrimination, differences in price charged across market segments reveal variations in demand elasticity, with higher prices typically charged in markets where demand is less price-sensitive, and lower prices in markets where demand is more elastic.

Profit Maximization

Profit maximization for a monopolist involves choosing the output level in each market where marginal revenue equals marginal cost, thereby maximizing total economic profit. This process takes into account the differences in demand across markets and the resulting impact on revenue, while cost considerations remain constant.

Price Discrimination

Price discrimination is a pricing strategy where a seller charges different prices for the same product in different markets or segments, based on factors like demand elasticity or consumer willingness to pay. This strategy allows a monopolist to capture more consumer surplus by tailoring prices to specific groups, thereby increasing overall profit.

Market Segmentation

Market segmentation involves dividing a broad consumer market into sub-groups of consumers with similar demand characteristics, preferences, or willingness to pay. This segmentation is critical for effective price discrimination, as it enables the seller to set distinct prices that maximize revenue across different segments.
