Formula

The formula for calculating the Lerner Index is:

L = (P – MC) / P

• L: Lerner Index
• P: Price of the product
• MC: Marginal cost of production

This formula highlights how much more the firm charges above its marginal costs, indicating its pricing power in the marketplace.

Example Calculation

Let’s say a company sells its product at $100 and incurs a marginal cost of $70. To find the Lerner Index, apply the formula:

L = (100 – 70) / 100 = 0.30

This result indicates a Lerner Index of 0.30, suggesting the firm has a significant degree of market power, which allows it to charge a price that is 30% higher than its marginal cost.

While the Lerner Index is a valuable tool, it has certain limitations:

• Market Variability: The index may not capture dynamic market conditions where prices fluctuate frequently.
