Unemployment


               13-1
Learning Objectives
1. Discuss the four important trends that have
   characterized labor markets in the U.S. since 1960
2. Apply a supply-and-demand model to understand
   the labor market
3. Explain how changes in the supply of and demand
   for labor explain trends in real wages and
   employment since 1960
4. Define and calculate the unemployment rate and
   the participation rate
5. Differentiate among the three types of
   unemployment and the costs associated with each
                                                        13-2
Trend 1: Increasing Real
              Wages
• Common in industrialized countries in the 20 th
  century




                                                    13-3
Trend 2: Slower Wage Growth
          Since 1973
• The annual rate of real wage growth is uneven
• Data on real wage growth:
  –   1960 – 1973    2.5% per year
  –   1973 – 1996   -1.1% per year
  –   1996 – 2009    2% per year
  –   1973 – 2009    0% per year




                                                  13-4
Trend 3: Increased Wage
        Inequality in US
• Between 1960 and 2009
  – Average real weekly earnings of production workers
    decreased
     • Real wages of the least-skilled, least-educated
       workers decreased 25 to 30%
  – Best-educated, highest-skilled workers' real wages
    increased
• Income with an advanced college degree is
  – Three times the income of a high school graduate
  – Four times the income of a worker who did not
    graduate from high school
                                                         13-5
Trend 4: Increasing
          Employment in US
• In 2007, 146 million people in the US had jobs
  – 46 million new jobs since 1980
• In 1970, 57% of the over-16 population had jobs
  – In 2007, 63% worked
• Between 1980 and 2007 employment increased
  46%
  – At the same time over-16 population increased 38%




                                                    13-6
The Labor Market
• Supply and demand analysis can be used to find
  the price of labor (real wages) and the quantity
  (employment)
  – Analysis will consider the number of workers
    employed, not work-hours per year
• Labor market is an input market
  – Firms buy labor to produce goods and services
• Macroeconomics look at aggregate levels of
  employment and real wages
  – Microeconomics looks at wage determination for a
    category of workers
                                                       13-7
Wages and Demand for Labor
• The demand for labor depends upon:
  – The productivity of workers
     • Greater productivity increases employment
  – The price of the worker’s output
     • A higher real price increases employment
• Diminishing returns to labor
  – Assumes non-labor inputs are held constant
  – Adding one worker increases output but by less
    than the previous worker added
• Value of Marginal Product (VMP) is extra
  revenue that an added worker generates
                                                     13-8
Banana Computers (BCC)
• BCC can sell all its computers for $3,000 each

Demand Curve for Labor
• Hire an extra worker if
  and only if the VMP
  exceeds the wage paid




                            Wage ($000s)
• If wage is $60,000,
                                           60
  BCC will hire 3
  workers                                  50
   – At $50,000, BCC
      hires 5 workers                                           Labor
• The lower the wage, the                                      Demand
  more workers employed                         3 5

Shifting Demand for Labor
• Demand shifts when the value of the marginal
  product of a worker changes
• Two factors determine the demand (VMP) for
  labor
  – The price of the company’s output
     • An increase in market demand
  – The productivity of the workers
     • Greater quantity of non-labor inputs
     • Organizational change
     • Training and education

                                                 13-11
Price of Output Increases
• If the price of computers increases, demand for labor
  shifts to the right
   – There is a separate

Higher Productivity
                          Increases in productivity
                           increase VMP
                          Demand curve shifts right
                          Employers hire more
                           workers at any given wage

Individual Labor Supply
• Reservation wage is the lowest wage a worker
  would accept for a given job
  – Opportunity cost of working is your leisure activity
  – Work compensates you for lost leisure
     • If working conditions are unpleasant or dangerous, a
       premium for that would be included in the wage
  – Cost – Benefit Principle at work




                                                           13-14
Aggregate Labor Supply
• Macroeconomic determinants of labor supply
  – Size of the working age population
     • Domestic birthrate
     • Immigration and emigration
     • Ages when people enter and retire from the
       workforce
  – Share of working-age population willing to work




                                                      13-15

                                     slopes up because at a
                                     higher real wage, more
                                     people are willing to
                                     work

                                                        13-16
Shifts in Labor Supply
• A shift in labor supply is caused by any change
  in the number of workers willing to work at each
  wage
  – Increase in the working-age population
     • Baby Boom
     • Higher net immigration
     • Increasing age at retirement
  – Increase in the share of working-age population
    willing to work
     • Women's participation in the labor force has
       increased in the last 50 years
                                                      13-17
Trend 1: Increasing Real Wages
• Industrialized countries have had sustained
  growth in productivity in the 20th century
  – Increases demand for labor
  – Both real wages and                                    S
    employment increased




                             Real Wage

Trend 2: Slower Wage Growth
          Since 1970
• Slower growth in real wages could be either
   – Slower growth in demand for labor OR
   – Faster growth in the supply of labor
• Productivity growth and real wages move together
                          Annual Growth Rate (%)
                      Productivity      Real Earnings
 1960 – 1970              2.34%             2.90%
 1970 – 1980              1.71              1.23
 1980 – 1990              1.60              0.71
 1990 – 2000              2.04              1.50
 2000 – 2008              2.60              0.68
                                                        13-19
Trend 2: Slower Wage Growth
          Since 1970
• Slower demand growth explains slower wage
  growth
  – Does not explain rapid growth in employment
• Supply of labor must have increased as well
  – Increased participation by women
  – Baby Boom
  – High rates of immigration
• Looking forward
  – Labor supply growth will slow
  – Partly depends on whether productivity growth
    continues                                       13-20
Trend 3: Increased Wage
         Inequality in US
• Globalization results in an expansion of many
  markets to worldwide supply
   – Increasing ease of goods and services crossing
     national borders
• Benefit of globalization is increased
  specialization and efficiency
   – Principle of Comparative Advantage
• Globalization also means that some goods
  produced domestically are no longer competitive
   – Some domestic sectors shrink

Trend 3: Increased Wage
         Inequality in US
• When wages in importing industries fall and wages
  in exporting industries rise, wage inequality
  increases
   – Low-skill industries in the US face the toughest
     international competition
   – Political resistance to free trade grows
• Worker mobility is the movement of workers
  between jobs, firms, and industries
   – Market incentives move workers out of textiles and into
     software
   – Transition aid by government can assist workers to
     make the change
                                                           13-23
Trend 3: Increased Wage
         Inequality in US
• Technological change can be a source of
  increasing wage inequality
  – Occurs if technical change favors higher-skilled or
    better-educated workers
• Some innovation renders old skills less valuable
  – Addition and the calculator and computer
• Skill-biased technological change affects the
  marginal products of higher skilled workers
  differently from those of lower-skilled workers
  – Recent changes favor higher skilled workers
  – Automobile production lines increasingly use robots

Costs of Unemployment
• Economic costs
  – Lost wages and production
  – Decreased taxes and increased transfers
• Psychological costs
  – Individual self-esteem
  – Family stress of decreased income and increased
    uncertainty
• Social costs
  – Potential increases in crimes and social problems
     • Social resources spent to address these

                                                        13-29
Duration of Unemployment
• Costs of unemployment are directly related to
  the length of time a person has been
  unemployed
  – Unemployment spell is the period during which an
    individual is continuously unemployed
  – Duration of unemployment is the length of the
    unemployment spell
• The unemployed population in March 2010
  Duration (weeks)   5 or less   5 – 14   More than 14
  % of unemployed      18%       22%         60%
                                                     13-30
Duration of Unemployment
• Long-term unemployed have been out of work
  for 6 months or longer
• Short-term unemployed have several possible
  outcomes
  – Find a permanent job after searching a few weeks
     • Economic costs are low
  – Leave the labor force
  – Short-term or temporary job that leads to
    unemployment again
     • These chronically unemployed have costs similar to
       the long-term unemployed
                                                        13-31
Other Unemployment Issues
• Discouraged workers would like to have a job but
  they have not looked for work in the past four weeks
   – Counted as out of the labor force
   – Willing and ready to work
   – Could be counted as unemployed but they are not
• Involuntary part-time workers are people who like to
  work full-time but cannot find a full-time job
   – Counted as employed
• March 2010 unemployment rate was 9.7%
   – Including discouraged workers and involuntary part-
     time workers would make the rate 16.9%
                                                      13-32
Types of Unemployment
• Frictional unemployment occurs when workers
  are between jobs
  – Short duration, low economic cost
  – May increase economic efficiency


• Cyclical unemployment is the increase in
  unemployment during economic slow-downs
  – Usually short duration
  – Economic cost is the decline in real GDP


                                               13-33
Types of Unemployment
• Structural unemployment is long-term, chronic
  unemployment in a well-functioning economy
  – Lack of skills, language barriers, or discrimination
  – Structural shifts in production create a long-term
    mismatch between workers and market needs
  – Barriers to employment such as
     • Minimum wages ■ Unions
     • Unemployment Insurance
  – High economic, psychological, and social costs
  – Example: US steel, telecommunications
    manufacturing
                                                           13-34

Structural Barriers to
             Employment
• Labor union benefits      • Labor union costs
  – Reduced worker            – Introduces
    exploitation                inefficiency into
  – Support progressive         competitive markets
    labor legislation         – May keep companies
  – Increase productivity       from competing
  – Promote democracy           globally
    in the workplace          – Increase labor supply
                                in non-union sector
                              – Decreases wages for
                                non-union workers
                                                   13-36
Structural Barriers to
             Employment
• Unemployment insurance is a government
  transfer to unemployed workers
  – Helps to reduce the costs of unemployment
  – May give the unemployed an incentive to search
    longer and less intensely
• To work efficiently, unemployment benefits
  should be
  – For a limited time
  – Less than the income received when working



                                                     13-37
Other Government Regulations
• Health and safety regulations can reduce the
  demand for labor by
  – Increasing employer costs
  – Reducing productivity
• The reduction in demand will increase
  unemployment and lower wages

    Learning Objectives 1. Discussthe four important trends that have characterized labor markets in the U.S. since 1960 2. Apply a supply-and-demand model to understand the labor market 3. Explain how changes in the supply of and demand for labor explain trends in real wages and employment since 1960 4. Define and calculate the unemployment rate and the participation rate 5. Differentiate among the three types of unemployment and the costs associated with each 13-2
  • 3.
    Trend 1: IncreasingReal Wages • Common in industrialized countries in the 20 th century 13-3
  • 4.
    Trend 2: SlowerWage Growth Since 1973 • The annual rate of real wage growth is uneven • Data on real wage growth: – 1960 – 1973 2.5% per year – 1973 – 1996 -1.1% per year – 1996 – 2009 2% per year – 1973 – 2009 0% per year 13-4
  • 5.
    Trend 3: IncreasedWage Inequality in US • Between 1960 and 2009 – Average real weekly earnings of production workers decreased • Real wages of the least-skilled, least-educated workers decreased 25 to 30% – Best-educated, highest-skilled workers' real wages increased • Income with an advanced college degree is – Three times the income of a high school graduate – Four times the income of a worker who did not graduate from high school 13-5
  • 6.
    Trend 4: Increasing Employment in US • In 2007, 146 million people in the US had jobs – 46 million new jobs since 1980 • In 1970, 57% of the over-16 population had jobs – In 2007, 63% worked • Between 1980 and 2007 employment increased 46% – At the same time over-16 population increased 38% 13-6
  • 7.
    The Labor Market •Supply and demand analysis can be used to find the price of labor (real wages) and the quantity (employment) – Analysis will consider the number of workers employed, not work-hours per year • Labor market is an input market – Firms buy labor to produce goods and services • Macroeconomics look at aggregate levels of employment and real wages – Microeconomics looks at wage determination for a category of workers 13-7
  • 8.
    Wages and Demandfor Labor • The demand for labor depends upon: – The productivity of workers • Greater productivity increases employment – The price of the worker’s output • A higher real price increases employment • Diminishing returns to labor – Assumes non-labor inputs are held constant – Adding one worker increases output but by less than the previous worker added • Value of Marginal Product (VMP) is extra revenue that an added worker generates 13-8
  • 9.
    Banana Computers (BCC) •BCC can sell all its computers for $3,000 each Number of Computers Marginal Value of Marginal Workers per Year Product Product 1 25 25 $75,000 2 48 23 69,000 3 69 21 63,000 4 88 19 57,000 5 105 17 51,000 6 120 15 45,000 7 133 13 39,000 8 144 11 33,000 13-9
  • 10.
    Demand Curve forLabor • Hire an extra worker if and only if the VMP exceeds the wage paid Wage ($000s) • If wage is $60,000, 60 BCC will hire 3 workers 50 – At $50,000, BCC hires 5 workers Labor • The lower the wage, the Demand more workers employed 3 5 Employment 13-10
  • 11.
    Shifting Demand forLabor • Demand shifts when the value of the marginal product of a worker changes • Two factors determine the demand (VMP) for labor – The price of the company’s output • An increase in market demand – The productivity of the workers • Greater quantity of non-labor inputs • Organizational change • Training and education 13-11
  • 12.
    Price of OutputIncreases • If the price of computers increases, demand for labor shifts to the right – There is a separate Real Wage ($000s) demand for labor curve for each 60 possible output price 50 Labor • An increase in the Demand (P = $5,000) price of workers' output increases the demand Labor Demand (P = $3,000) for labor 3 5 7 8 Employment 13-12
  • 13.
    Higher Productivity  Increases in productivity increase VMP  Demand curve shifts right  Employers hire more workers at any given wage Real Wage Labor Demand (after productivity increase) Labor Demand (before productivity increase) Employment 13-13
  • 14.
    Individual Labor Supply •Reservation wage is the lowest wage a worker would accept for a given job – Opportunity cost of working is your leisure activity – Work compensates you for lost leisure • If working conditions are unpleasant or dangerous, a premium for that would be included in the wage – Cost – Benefit Principle at work 13-14
  • 15.
    Aggregate Labor Supply •Macroeconomic determinants of labor supply – Size of the working age population • Domestic birthrate • Immigration and emigration • Ages when people enter and retire from the workforce – Share of working-age population willing to work 13-15
  • 16.
    The Supply ofLabor Labor Supply Real Wage The labor supply curve slopes up because at a higher real wage, more people are willing to work Employment 13-16
  • 17.
    Shifts in LaborSupply • A shift in labor supply is caused by any change in the number of workers willing to work at each wage – Increase in the working-age population • Baby Boom • Higher net immigration • Increasing age at retirement – Increase in the share of working-age population willing to work • Women's participation in the labor force has increased in the last 50 years 13-17
  • 18.
    Trend 1: IncreasingReal Wages • Industrialized countries have had sustained growth in productivity in the 20th century – Increases demand for labor – Both real wages and S employment increased Real Wage • Productivity increases W' were due to W – Technological progress D D' – Increases in capital N N' Employment 13-18
  • 19.
    Trend 2: SlowerWage Growth Since 1970 • Slower growth in real wages could be either – Slower growth in demand for labor OR – Faster growth in the supply of labor • Productivity growth and real wages move together Annual Growth Rate (%) Productivity Real Earnings 1960 – 1970 2.34% 2.90% 1970 – 1980 1.71 1.23 1980 – 1990 1.60 0.71 1990 – 2000 2.04 1.50 2000 – 2008 2.60 0.68 13-19
  • 20.
    Trend 2: SlowerWage Growth Since 1970 • Slower demand growth explains slower wage growth – Does not explain rapid growth in employment • Supply of labor must have increased as well – Increased participation by women – Baby Boom – High rates of immigration • Looking forward – Labor supply growth will slow – Partly depends on whether productivity growth continues 13-20
  • 21.
    Trend 3: IncreasedWage Inequality in US • Globalization results in an expansion of many markets to worldwide supply – Increasing ease of goods and services crossing national borders • Benefit of globalization is increased specialization and efficiency – Principle of Comparative Advantage • Globalization also means that some goods produced domestically are no longer competitive – Some domestic sectors shrink 13-21

    Trend 3: IncreasedWage Inequality in US • When wages in importing industries fall and wages in exporting industries rise, wage inequality increases – Low-skill industries in the US face the toughest international competition – Political resistance to free trade grows • Worker mobility is the movement of workers between jobs, firms, and industries – Market incentives move workers out of textiles and into software – Transition aid by government can assist workers to make the change 13-23
  • 24.
    Trend 3: IncreasedWage Inequality in US • Technological change can be a source of increasing wage inequality – Occurs if technical change favors higher-skilled or better-educated workers • Some innovation renders old skills less valuable – Addition and the calculator and computer • Skill-biased technological change affects the marginal products of higher skilled workers differently from those of lower-skilled workers – Recent changes favor higher skilled workers – Automobile production lines increasingly use robots 13-24

Editor's Notes

  • #23 Domestic market starts in equilibrium at wage W. N T workers are in the textile industry and N S workers are in the software industry. Globalization opens borders and US begins importing textiles and exporting software. Demand for domestic textiles decreases as some textiles are bought overseas. This decreases the wage in the textile idustry to W' T and employment decreases to N' T. The opposite happens in the software industry. Exports cause an increase in demand, employment, and wages. The result is a wage differential (W' S – W' T ) where none existed before.
