Employment and Unemployment

EMPLOYMENT AND UNEMPLOYMENT

• Introduction: Unemployment has severe economic, social, and psychological impacts on those affected.

Measuring Employment and Unemployment

• Definition of Potential Workers:

  • The civilian non-institutional population includes everyone except:

  • Children under 16 years

  • Active military personnel

  • Institutionalized persons (e.g., in nursing homes or jails)

• Population Statistics for 2025:

  • Total Population: 347.3 million

  • Excluded Individuals (Children + Active Military + Institutionalized): 72.48 million

  • Potential Workers: 274.82 million

Categories of Potential Workers:

1. Employed Persons:

   • Hold a paid full-time or part-time job.

2. Unemployed Persons:

   • Individuals without a job who have actively searched for one in the last four weeks and are available for work.

3. Not in Labor Force:

   • Individuals without a paid job and not actively searching for one.

• Labor Force Definition:

  • Labor Force = Employed + Unemployed

  • Size of the labor force does not provide insights into the “intensity” of work.

• Labor Force Statistics for 2025:

  • Not in Labor Force: 103.32 million

  • Employed: 163.99 million

  • Unemployed: 7.50 million

  • Total Labor Force: 171.50 million

• Participation Rates:

  • Labor Force Participation Rate (LFPR) = $rac{Labor\,Force}{Potential\,Workers} imes 100$

  • Employment Population Ratio (EPR) = $rac{Employed}{Potential\,Workers} imes 100$

  • Employment Rate (ER) = $rac{Employed}{Labor\,Force} imes 100$

  • Unemployment Rate (UR) = $rac{Unemployed}{Labor\,Force} imes 100$

Example of Calculating Labor Market Data (2025):

• Data (in Millions):

  • National Population = 347.30

  • Children, Active Military, Institutionalized = 72.48

  • Civilian Non-institutionalized Population = 274.82

  • Not in Labor Force = 103.32

  • Labor Force = Employed + Unemployed = 171.50

  • Employed = 163.99

  • Unemployed = 7.50

  • LFPR = rac{171.50}{274.82} imes 100 = 62.4 ext{%}

  • EPR = rac{163.99}{274.82} imes 100 = 59.7 ext{%}

  • ER = rac{163.99}{171.50} imes 100 = 95.6 ext{%}

  • UR (U-3) = rac{7.50}{171.50} imes 100 = 4.4 ext{%}

  • U.S. Bureau of Labor Statistics

Employment Data Charts:

• Civilian Unemployment Rate:

  • Trend includes data for Total, White, Black or African American, Asian, and Hispanic or Latino demographics across time.

  • Shaded areas indicate recessions as per National Bureau of Economic Research.

• Labor Force Participation Rate:

  • Illustrated by demographic trends over several years.

• Employment-Population Ratio:

  • Visual representation adjusts for seasonality and economic fluctuations.

Alternative Measures of Labor Underutilization:

• Data for 2025 (in Millions):

  • Total Labor Force = 171.50

  • Employed = 163.99

  • Unemployed = 7.50

  • Marginally Attached Workers = 5.34

  • Discouraged Workers = 1.67

  • Total Unemployment Rates:

  • U-3: 4.4%

  • U-4: 4.6%

  • U-5: 5.3%

  • U-6: 8.4%

Educational Attainment and Unemployment Rate:

• Statistics on unemployment rates segmented by educational achievement.

• Levels compared range from less than a high school diploma to bachelor’s degrees and higher.

Equilibrium in the Labor Market

• Labor Market Dynamics:

  • Equilibrium wage and labor quantity determined by the interaction of labor demand (firms) and labor supply (workers).

Labor Demand:

• Firms seek profit maximization:

  • Profit function defined as:
    $ext{Π} = ext{Total Revenue} - ext{Total Costs}$

  • Total Revenue as $PQ$ (with Q depending on inputs K,L).

  • Total Costs expressed as $wL + rk$, with w as wage, r as rental output.

  • Price-taking firms cannot influence output/input prices; they will hire additional workers as long as marginal benefit exceeds marginal cost.

Marginal Product of Labor (MPL):

• Definition:

  • Value of the output produced by the last unit of labor (VMPL).

  • Calculated as:
    $ext{VMPL} = P imes ext{MPL} = rac{ ext{ΔTotal Revenue}}{ ext{ΔL}}$

• Firms will hire labor until VMPL equals market wage (w):
  $ext{VMPL} = w$

Example of Labor Demand:

• Calculating Total Revenue and Marginal Product:

  Number of Cooks	Total Meals Produced	Price per Meal	Total Revenue	Value of Marginal Product of Labor	Market Wage
  1	4	$10	$40	$40	$20
  2	7	$10	$70	$30	$20
  3	9	$10	$90	$20	$20
  4	10	$10	$100	$10	$20

• Conclusion: The firm will hire three cooks because at 3 cooks the VMPL equals the market wage of $20.

Labor Demand Curve:

• Characteristics:

  • Represents the relationship between labor demand quantity and wage.

  • Slopes downward due to the Law of Diminishing Marginal Product.

  • Shifts due to changes in output price, demand for the good, technological advancements, and input prices.

Labor Supply:

• Worker Behavior:

  • Labor supplied relates to how workers allocate their time between paid work, leisure, and home activities.

  • Opportunity cost of leisure is the wage forgone.

Factors Influencing Labor Supply Dynamics:

1. Changes in wages affect supply positively (upward sloping).

2. Supply shifts due to:

   • Tastes/preferences

   • Opportunity costs of time

   • Demographic changes

Market Equilibrium:

• Occurs at the intersection of labor supply and labor demand.

• At equilibrium wage (w*), quantity of labor demanded equals quantity of labor supplied.

Causes of Unemployment

1. Frictional Unemployment:

   • Occurs due to imperfect information and the time-consuming nature of job searching.

2. Structural Unemployment:

   • Arises from persistent gaps between labor supply (Ls) and demand (Ld).

   • Causes include skill deficiencies and wage rigidity (market wages held above equilibrium).

   • Example of Wage Rigidity Factors:

     • Minimum wage laws

     • Labor unions

     • Efficiency wages

     • Worker aversion to lower wages.

3. Cyclical Unemployment:

   • Relates to business cycle fluctuations; calculated as the difference between current and natural unemployment rates:
     ext{Cyclical Unemployment} = u - ar{u}

• Estimates of Natural Unemployment Rate:

  • Data from various periods showing rates estimated across decades.

• Impact of Automation:

  • Concerns arise regarding employment and unemployment dynamics due to automation.

Key Ideas:

1. Potential workers are categorized into employed, unemployed, and not in the labor force.

2. Employment levels and wages depend on labor demand and supply, and wage rigidities.

3. Frictional and structural unemployment stems from market inefficiencies and search frictions.

4. Cyclical unemployment reflects economic downturns and variations from long-term trends.
