Study Notes on Union Wage Setting and Labor Demand

Introduction to Labor Demand and Union Wage Setting

• Overview of the relationship between wage changes and labor demand.
• Employment losses as a result of wage increases.

Union Wage Setting as a Monopoly

• Unions behave like monopolists in wage setting.
• Important to consider the union's preferences:
  • Wages and employment are both crucial for the union.
  • Unions aim to balance wage demands with the retention of jobs.

Indifference Curves in Union Decision-Making

• Use of indifference curves to model union preferences:
  • Utility from both wages and employment.
  • Indifference curves are downward sloping.
  • As wages decrease, employment increases, holding utility constant.
  • Higher indifference curves represent higher utility levels.

Objective Function of the Union

• Unions seek to maximize utility jointly for all workers.
• Components of utility:
  • Pay (wage level).
  • Employment level.

Demand Function and Its Implications

• Demand function arises from firms maximizing profits.
  • Typically, it is downward sloping.
  • The relationship indicates that lower wages lead to higher employment demand.
• Firms determine hiring levels based on profit motives.
• The union cannot directly control employment levels but factors into their wage demands.
• The demand function acts as a constraint on the union's wage-setting capacity.

Maximizing Utility Subject to Demand Function

• Union maximizes utility considering the demand function as a constraint:
  • Solution found at a tangency point between the union's indifference curve and the labor demand function.
• Representation of optimal wage ($WM$) and corresponding employment level (employmentm).

Elasticity of Labor Demand

• Two scenarios with different elasticity of labor demand:
  • Less Elastic Demand:
  • Steeper curve.
  • Wage increases lead to smaller employment losses.
  • Union can demand higher wages with minimal employment loss.
  • Result: Higher indifference curve achievable.
  • More Elastic Demand:
  • Flatter curve.
  • Wage increases lead to larger employment losses.
  • Union faces greater constraints.

Factors Affecting Labor Demand Elasticity

• Changes in technology or shifts in industry can affect labor demand elasticity:
  • Increased productivity may reduce reliance on labor, making demand more elastic.
  • Globalization could lead to outsourcing, impacting labor elasticity.

Implications of Union Wage Setting

• Monopoly unions typically result in a loss of economic surplus:
  • Wages are often set above equilibrium due to unionization.
  • Higher wages lead to unemployment, similar effects to a government-imposed minimum wage.
  • Surplus shrinkage among workers and producers.

Comparative Analysis of Labor Markets

• Representation of labor markets with varying wage structures:
  • Unionized sectors versus competitive sectors.
  • Movement of workers may raise wages in competitive sectors, but those wages cannot fall in unionized sectors.
• Result: Potential for unemployment and reduced overall economic efficiency in unionized markets.

Conclusion on Monopoly Union Model

• The monopoly union model presents complexities in labor market dynamics and wage setting.
• It raises questions about efficiency, surplus distribution, and the impact of external factors on labor demand.
