Questions

Lerner Index Calculator FAQ

What does a Lerner index value of 0.5 mean?
A value of 0.5 means the firm sets its price at twice its marginal cost, indicating moderate market power where the price exceeds marginal cost by 50 percent.
Can the Lerner index be negative?
No, the Lerner index ranges from 0 to 1; a value of 0 means price equals marginal cost (perfect competition), while values approaching 1 indicate strong market power.
How is the Lerner index different from profit margin?
The Lerner index compares price to marginal cost, whereas profit margin compares price to total cost; the index focuses on market power rather than overall profitability.
Is a higher Lerner index always better for a firm?
Not necessarily; a very high index may signal limited competition and potential regulatory scrutiny, while a low index often reflects competitive markets that benefit consumers.
