Determinants of Wage Differences

  • Compensating Differentials: Higher wages for risky or unpleasant jobs to attract workers.
  • Human Capital: Investments in education and training that increase worker productivity and earnings.
  • Ability, Effort, and Chance: Natural talent and hard work also influence wages.
  • Signaling: Education may signal ability rather than increase productivity.
  • Superstar Phenomenon: A few highly skilled individuals earn outsized incomes due to scalable technologies.

Above-Equilibrium Wages

Some wages exceed competitive equilibrium levels due to:

  • Minimum Wages: Legal price floors on wages.
  • Labor Unions: Organizations that negotiate higher wages and better conditions.
  • Efficiency Wages: Firms pay above-market wages to boost productivity and reduce turnover.

Discrimination in Labor Markets

Despite competitive pressures, wage disparities persist due to various forms of discrimination:

  • Employer Discrimination: Firms discriminate but risk reduced competitiveness.
  • Customer Discrimination: Consumer preferences can sustain wage gaps.
  • Statistical Discrimination: Employers rely on group averages rather than individual merits.

Competitive markets may reduce employer discrimination over time, but systemic factors and social preferences continue to influence outcomes.
