how is labor market discrimination related to poverty
How is labor market discrimination related to poverty?
  • Labor market discrimination depresses the earnings of minorities and women.
  • Consequently, minorities and women are overrepresented among the poor.
  • Labor market discrimination affects how many will be poor (depressed earnings) and who will be poor (members of minority groups).
what is discrimination
What is discrimination?
  • Consider the case of a taxi driver who is driving down a one-way street at night in a dangerous part of town and is hailed simultaneously by people on each side of the street. It is equally easy for her to pick up either customer. On the left side of the street is a little old lady. On the right side is a tall African-American teenage boy wearing a hood. The taxi driver unhesitatingly chooses the little old lady over the teenager. Did she discriminate? Is she a racist?
what is discrimination cont
What is discrimination?, cont.
  • Discrimination: Treating people differently on the basis of their membership in a class
    • Discrimination need not imply racism, sexism, or prejudice.
  • Prejudice: dislike, distaste, or misperception based on innate characteristics such as race or sex
    • Prejudice can but need not generate discrimination.
what is labor market discrimination
What is labor market discrimination?
  • Employment (hiring and hours worked), wage, and promotion practices that result in workers who are equal with respect to their productivity being treated differently because of their race, gender, age, ethnic group, or other characteristics unrelated to their job performance.
    • Discrimination: any situation in which individuals with identical observed characteristics have systematically different outcomes.
what is labor market discrimination9
What is labor market discrimination?
  • These practices lead to lower earnings by affecting hours and/or wage rates:

Earnings = hours x wage rate

how large is the black white wage gap
How large is the black/white wage gap?
  • The mean earnings of full-time black workers 25 years and older were 32 percent less than comparable whites in 2004.
    • The Black/White ratio is 0.68;
    • Asian/white ratio is 1.03;
    • Hispanic/White (not Hispanic) is 0.66

how large are the female male wage gap
How large are the female/male wage gap?
  • The median earnings of full-time, year-round female workers 15 years and over were 27 percent less than males in 2004.
    • The female/male ratio was 0.77.

how do we explain the wage gaps theoretically
How do we explain the wage gaps theoretically?
  • Discrimination is usually thought of as market discrimination—that is the current practices of employers.
  • Assumptions
    • Labor markets work smoothly, unless otherwise stated
    • All workers are equallyproductive innately
    • Firms are profit maximizers, unless otherwise stated
models of discrimination cont
Models of Discrimination, cont.
  • Becker’s theory personal prejudice or tastes for discrimination:
    • by employers who care about the characteristics of their employees as well as profits!
      •  leads to segregated but equally paid workforces
    • by co-workers (including unions)  leads to segregated but equally paid workforces
    • by customers
      •  leads to segregation on basis of the visibility of job, and equal pay
      •  may lead to discrimination (unequal pay) if job requires visibility
        • Example: professional sports
models of discrimination cont14
Models of Discrimination, cont.
  • Imperfect MarketsDiscrimination
    • Firms do not fill vacancies instantly and workers need time to find jobs
    • Firms do not adjust wages instantly in response to the number of applications they receive.
results of imperfect markets
Results of Imperfect Markets
  • Knowing they are at a competitive disadvantage, the persons subject to prejudice will
    • avoid applying for jobs (high-wage) that attract other workers.
    • Experience more unemployment if they do apply
    • May be willing to accept lower wages
    • Accept jobs that are poor matches for their skills unwittingly reinforcing discrimination.
models of discrimination cont statistical discrimination
Models of Discrimination, cont.Statistical Discrimination
  • Assumptions about Firms:
    • Seek to maximize profits
    • Are not prejudiced
    • Use characteristics (race, gender) to draw inferences about workers that are correct, on average.
    • Identify two types of workers, good and bad, who are present in equal numbers in all groups
    • Can observe the productivity of individuals in only one group (whites for example), and treats all members of other groups according to the groups average.
models of discrimination statistical discrimination cont
Models of DiscriminationStatistical Discrimination, cont.
  • In this model, discrimination results (workers of equal productivity earn different amounts) when the lack of information about individuals ends up reducing their productivity
  • One way productivity is reduced is when a lack of information interferes with the appropriate matching of workers to jobs.

how do we measure discrimination in the labor market
How do we measure discrimination in the labor market?
  • Decomposition of wage differentials
    • What portion of the wage gap is due to human capital factors?
    • Another way to state this is to ask what portion of the wage gap is due to differences in productivity?
      • Look for differences in education, training, and experience.
    • The portion of the wage gap not explained by these differences is attributed to discrimination.

interpretation of the graph
Interpretation of the Graph
  • Male earnings function is steeper and thus shows a greater payoff for additional investments in human capital.
  • Xf and Xm represent average levels of human capital for females and males respectively
  • wf is the average wage earned by a female with average female human capital
  • wm is the average wage earned by a male with average male human capital
interpretation of the graph24
Interpretation of the Graph
  • wm - wf is the female/male wage gap
  • wfbm is the wage women would earn if they received the same reward for additional investments in human capital as men.
  • AB or wm - wfbm is the portion of the wage gap due to differences in human capital
  • BC or wfbm-wf is the portion of the wage gap due to discrimination
how much of the wage gaps are explained by labor market discrimination
How much of the wage gaps are explained by labor market discrimination?
  • White-Black Wage Gap
    • Hyclak et al. assert thatnoneof the wage gapbetween white and minority workers is due todiscrimination! Schiller reports that one-fourth of the wage gap is due to discriminatory labor practices (p. 194).
    • This implies that human capital differences explain ¾ to all of the Black/White wage gap.
how much of the wage gaps are explained by labor market discrimination cont
How much of the wage gaps are explained by labor market discrimination?, cont.
  • Male-Female Wage Gap
    • Human capital: Education and experience explain only6 percent. Controlling for measures of education and experience reduce the gap from 29 percent to 27 percent
    • Almost theentire gapis attributed todiscrimination!
are there limitations of the decomposition method
Are there limitations of the decomposition method?
  • The decomposition method assumes
    • The differences in the observed amounts of human capital (the Xs) are not affected by discrimination.
    • The Xs represent all the relevant variables having nothing to do with discrimination. Might we have overlooked some?
    • Minority groups do not prefer work in jobs that are poorly paid.
how does nonmarket discrimination figure into this model of discrimination
How does nonmarket discrimination figure into this model of discrimination?
  • Nonmarket discrimination influences the amount of human capital investment, and hence the values of the Xs in the decomposition model
    • Black workers are much more likely than white workers, on average, to come from families with lower incomes, to live in poor neighborhoods, and to attend inferior schools.
how preferences figure into this model of discrimination
How preferences figure into this model of discrimination?
  • Preferences may lead minority members to opt for lower paying jobs.
  • Preferences are most often called into service when we think of the wage gap between men and women, but could also apply to wage differences between wages or ethnic groups.
why would the labor market preferences of men and women differ
Why would the labor market preferences of men and women differ?
  • Tastes for parenting
  • Physical attributes
  • Societal and parental expectations—How are these formed?
    • Past discrimination
    • Anticipated discrimination (Statistical discrimination becomes a self-fulfilling prophecy.)
how does recognizing these limitations affect our estimates of discrimination
How does recognizing these limitations affect our estimates of discrimination?
  • The portion of the wage gaps attributed to differences in human capital may be overstated and the portion attributed to discrimination may be understated.
how is discrimination related to earnings income inequality
How is discrimination related to earnings/income inequality?
  • Work by Juhn and others has shown that the wage differential between majority and minority workers, between men and women is connected to inequality (the overall dispersion) in the distribution of earnings.
    • An increase in inequality can result in an increase in the wage gaps.
are the wage gaps narrowing growing or staying the same
Are the wage gaps narrowing, growing, or staying the same?
  • The black/white differential has stagnated since the 1970s.
    • Blacks are over represented in lower part of the wage distribution.
    • Returns to schooling increased. Gains in more schooling among blacks offset by increased rates of return to high levels more likely to be achieved by whites.
    • Relocation of jobs to suburbs hurt blacks more than whites.
are the wage gaps narrowing growing or staying the same34
Are the wage gaps narrowing, growing, or staying the same?
  • Between 1960 and 1980, women earned 60 percent of what men earned
  • Since 1980, there has been a steady and rapid rise in the relative earnings of women.
  • In 2005, women earned 77 percent of what men earned on average.
    • Five percentage points or 1/3 of the change is due to increased schooling among women.
    • Decline in unionization and shift in jobs from manufacturing to service industries lowered male wages.
factors narrowing the female male wage gap
Factors narrowing the female/male wage gap
  • Increased experience
    • New workers represent a small share of all female workers; hence their lower earnings do not pull down the median as it did before 1980.
  • Decline in unionization (men’s wages fell)
  • Shift of women into higher paying occupations
  • Increased relative education of women.
  • Reduced discrimination in the market?
