Study Notes

Chapter 4: Labor Market Equilibrium

Labor market equilibrium balances firm and worker desires, determining observed wages and employment levels.
Different market structures (monopsony, monopoly) result in unique equilibria.
- Monopsony: one buyer of labor
- Monopoly: one seller of labor

Equilibrium in a Single Competitive Labor Market

Competitive equilibrium occurs when supply equals demand, leading to a competitive wage and employment level.
Real-world labor markets are dynamic, rarely in perfect equilibrium, constantly moving towards that state.

Efficiency

Pareto efficiency exists when all potential gains from trade are exhausted.
In a Pareto-efficient state, improving one person's well-being inevitably reduces another person's.
Policy changes are "Pareto-improving" if they benefit at least one party without harming others.

Equilibrium in a Competitive Labor Market

Equilibrium in a competitive labor market occurs when labor supply equals labor demand (E*).
At this equilibrium, all workers seeking employment at the prevailing wage (w*) are able to find jobs.
Producer surplus (P) and worker surplus (Q) are maximized in a competitive market. The sum of producer and worker surplus (P + Q) is the maximized value of output.

Competitive Equilibrium Across Labor Markets

Free movement of labor and labor market entries/exits result in a uniform wage for all workers.
Worker allocation to firms where their marginal product is equalized maximizes national income (allocative efficiency).
This "invisible hand" process results from pursuing self-interest.

Efficiency Revisited

In competitive equilibrium, wages equal the value of a worker's marginal product.
This equalizes wages across different markets, eliminating regional wage differences.
Efficient allocation of labor across markets results from workers and firms seeking highest possible returns.

Wages and International Trade: NAFTA

NAFTA established a free trade zone in North America.
Free trade reduced income disparities and maximized the total income of countries within the zone due to equalized economic opportunities.

Competitive Equilibrium in Two Labor Markets Linked by Migration

Worker migration to higher-paying regions leads to wage equalization across regions.
The supply and demand curves shift until wages are equalized across areas.

Wage Convergence Across States

Data shows a tendency for wage convergence among US states over time.

Payroll Taxes and Subsidies

Payroll taxes (imposed on employers) lead to a parallel shift down in labor demand.
- Creates a wedge between the amount firms pay and workers receive.
Taxes reduce employment as they increase total costs of employment.
Costs are shared between firms and workers, with wage decreases to offset the increased cost for firms.
Payroll taxes cause deadweight losses.

Payroll Subsidies

Employment subsidies reduce hiring costs for firms.
This shifts the labor demand curve to the right.
Total employment increases as the cost of hiring has fallen.

The Impact of a Mandated Benefit

A mandated benefit increases costs to employers, reducing the demand for labor, leading to lower wages.

Immigration

Immigration increases the labor supply, shifting the labor supply curve to the right.
Overall employment increases.
Equilibrium wages decrease.

Effect on Native-Born Workers

Immigration can reduce wages for similarly skilled native workers.
However, natives may increase productivity by specializing in more suitable tasks.
Some natives' employment might be impacted, while others may experience increased wages due to complementarity with immigrants.

The Short-Run Impact of Immigration When Immigrants and Natives Are Perfect Substitutes

When immigrants are perfect substitutes for natives, immigration increases labor supply resulting in reduced wages and a decline in the number of native workers employed.
The short-run impact of immigration is a lower wage for all workers.

The Short-Run Impact of Immigration When Immigrants and Natives Are Complements

When immigrants are complements to natives, immigration boosts labor demand resulting in higher wages and greater employment among natives.
The short-run effect of immigration boosts native employment and wages.

The Long-Run Impact of Immigration When Immigrants and Natives Are Perfect Substitutes

Over time, capital expands, and labor demand increases, eventually restoring the original level of wage and native employment.
The long-term effect of immigration often sees a return to equilibrium wages for native workers despite initial reductions.

Scatter Diagram Relating Wages and Immigration for Native Skill Groups

Studies show a negative correlation between immigration and the wages of native workers with similar skills.

The Short-Run Labor Demand Curve Implied by Different Natural Experiments

In certain cases, increased immigration has no effect on wages in the short run.
Other cases show that minimum wage laws don't affect employment levels in the short run.

Policy Application: High-Skill Immigration

High-skill immigration can bring benefits to host countries by expanding human capital.
This can boost native productivity and enhance the economy through beneficial spillover effects.

Policy Application: COVID-19 and the U.S. Labor Market

The Covid-19 pandemic caused a significant contraction in employment.
Predicting future trends in the labor market is challenging due to the uncertainty of the pandemic's evolution.

Noncompetitive Labor Markets: Monopsony

Monopsony is a market condition where a single buyer of labor (a firm) exists.
Monopsonists face an upward-sloping labor supply curve, requiring increases to attract more workers.

Perfectly Discriminating Monopsonist

Discriminating monopsonists can hire various workers at different wages.
To maximize profits, they pay each worker their reservation wage.

Nondiscriminating Monopsonist

Nondiscriminating monopsonists must pay all workers the same wage, regardless of reservation wage.
This results in the hiring of fewer workers compared to a competitive market.

The Hiring Decision of a Perfectly Discriminating Monopsonist

Perfectly discriminating monopsonists face an upward-sloping labor supply curve.
They maximize profits by choosing the employment level where the marginal cost of hiring equals the value of the marginal product (VMP).

The Hiring Decision of a Nondiscriminating Monopsonist

Non-discriminating monopsonists must offer the same wage to all workers.
They hire workers up to the point where the marginal cost of hiring equals the value of the marginal product (VMP).

The Impact of the Minimum Wage on a Nondiscriminating Monopsonist

Minimum wage laws can both increase wages and employment for workers in monopsonistic labor markets.
