When do monopolists charge a higher markup?

Monopolists charge a higher markup when demand is highly inelastic because consumers are less sensitive to price changes. In this scenario, a price increase would not significantly reduce the quantity demanded, allowing the monopolist to raise prices without losing many sales. This situation typically occurs when there are few or no close substitutes for the product, meaning consumers have limited options and are more likely to continue purchasing despite higher prices.

As a result, the monopolist can maximize profits by increasing the price significantly, knowing that most consumers will still buy the product. In contrast, when demand is elastic, a price increase would lead to a substantial drop in sales, prompting the monopolist to keep prices lower to maintain sales volume. Thus, understanding the nature of demand elasticity is crucial for monopolists in setting their pricing strategies effectively.
