Symmetry Between Price Markup and Wage Markdown
A direct parallel exists between a firm's power in the product market and its power in the labor market. This symmetry is captured by the price markup (μ) and the wage markdown (η). The price markup measures a firm's power over consumers by showing how far the price is set above marginal cost, and it is high when product market competition is low. Symmetrically, the wage markdown measures a firm's power over workers by showing how far the wage cost per unit is set below marginal cost, and it is high when labor market competition is low.

Symmetry Between Price Markup and Wage Markdown
Effect of Labor Market Competition on Wage Markdown (η)
A large manufacturing plant is the only major employer in a remote town. In a major industrial city, dozens of similar plants actively recruit from the same labor pool. Assuming worker productivity is identical in both locations, how would the 'wage markdown'—the proportional gap by which a firm's marginal cost of output exceeds its wage cost per unit—compare between the two locations, and what is the underlying reason for this difference?
Calculating and Interpreting the Wage Markdown
Symmetry in Market Power: Wage Markdown vs. Price Markup
A manufacturing firm observes that its wage markdown, the parameter that measures the proportional difference between its marginal cost of output and its wage cost per unit, has increased from 0.10 to 0.15. Assuming worker productivity remains constant, which of the following statements accurately interprets this change?
A firm observes that its wage markdown—the proportional gap between its marginal cost of output and its wage cost per unit—has increased. This change implies that competition among firms for labor has become more intense.
A firm with significant power in its local labor market has a marginal cost of output of $30. The average productivity of its labor is 3 units per hour. Given this information, which of the following hourly wage rates is most consistent with the firm's market position?
Explaining the Wage Markdown
A company determines that the marginal cost of producing one additional unit of its product is $12. The wage cost associated with producing that same unit is $10. Based on this information, what is the value of the firm's 'wage markdown', which represents the proportional gap between the marginal cost and the wage cost per unit?
Match each labor market scenario with its most likely effect on a firm's wage markdown (η). The wage markdown represents the proportional gap by which a firm's marginal cost of output exceeds its wage cost per unit.

Monopoly and Monopsony Market Power
A company is the sole producer of a unique, patented pharmaceutical drug, giving it significant control over the product's price. However, the company's research labs are located in a major city where it must compete with numerous other firms to hire qualified scientists. Based on this situation, what is the most likely combination of the firm's price markup over its marginal cost and its wage markdown below its marginal cost?
Evaluating the Impact of Antitrust Policy
Market Power in Different Locations
Match each market condition to the most likely outcome for a firm's pricing and wage-setting behavior, based on its resulting market power.
A firm that faces intense competition for its products but is one of the few major employers in its town would likely exhibit both a low price markup and a low wage markdown.
Explaining Market Power Symmetry
An increase in the number of competing firms in the product market will most likely lead to a ____ in the price markup, while an increase in the number of firms competing for workers in the labor market will most likely lead to a ____ in the wage markdown.
Just as the price markup quantifies a firm's market power over consumers by measuring how far the price is set above marginal cost, the wage ____ quantifies the firm's market power over workers by measuring how far the wage cost is set below marginal cost.
Analyzing Asymmetric Market Power
A firm operates in a labor market that was previously competitive. Arrange the following events in the correct logical sequence to show how a decrease in labor market competition leads to a higher wage markdown.
