and the sale of assets to fund consumption and can receive income supplements such as Supplemental
Nutrition Assistance Program (SNAP) benefits and rent subsidies.
27. Evaluate and explain: “If poverty is defined as an absolute deficiency of income, the poor are far better off
today than they were four decades ago. But if poverty is viewed as relative deprivation, of being worse off
than the people to whom a poor person compares himself or herself, then poverty today may be more
painful than four decades ago.”
This statement recalls the old adage, “the poor are always with us.” If poverty is defined in relative terms,
barring total equality, there will always be a group in the lowest quintile of income earners, another in the
28. (Consider This) Define a welfare cliff.
A welfare cliff is a point at which employed welfare recipient’s overall income will fall if they earn more
29. (Consider This) Describe the “unintended consequences” of a system in which a welfare cliff exists.

benefits. The major examples of public assistance programs are Temporary Assistance to Needy Families

Income (SSI) for age or disability, and the Earned Income Tax Credit (EITC).

Families (TANF).

39. How can discrimination be viewed as resulting from a preference or taste for which the prejudiced
employer is willing to pay? What will determine whether the prejudiced employer hires nonpreferred
workers in this model?
40. Suppose an employer is considering hiring either a white worker or an African-American worker for a
position. Consider the following conditions and decide which worker the employer is likely to hire.
(a) The employer is prejudiced against African-Americans and it costs him a disutility of $3/hour to hire
the African-American. Suppose the African-American is willing to work for $9/hour, while the white
worker will work for $11/hour. Whom will the employer hire?
(b) The employer is prejudiced against African-Americans and it costs him a disutility of $2/hour to hire
the African-American. Suppose the African-American is willing to now work for $8/hour, while the
white worker will work for $11/hour. Whom will the employer hire?
(c) The employer has no preference between the white and African-American workers. Suppose the
African-American and the white workers are both willing to work for $12 an hour. Whom will the
employer hire?
(a) The employer will hire the white worker. The employer will only be willing to pay a wage of
41. How might competition eradicate discrimination? Historically, has this been observed?
42. Explain the concept of statistical discrimination and give an example of it. How can it lead to
discrimination even in the absence of prejudice?
43. Explain the two models/theories of discrimination.
The taste-for-discrimination model views discrimination resulting from preferences or tastes. This theory
explores the willingness-to-pay that people pay to avoid the nonpreferred group. The size of the payment
depends on the degree of prejudice.
44. Consider the following situations and decide which model of discrimination is being exhibited: taste-for-
discrimination or statistical discrimination.
(a) Health insurance is higher for smokers than for non-smokers.
(b) An employer prefers not to higher teenagers.
(c) An employer chooses a female to fill a position of secretary, because women tend to be multi-taskers.
(d) An employer does not hire African-American workers.
45. “Job discrimination may actually result from rational decision making on the part of firms and not because
of prejudice.” Explain this statement.
46. Describe the economic effects of occupational segregation on the wages of women and minorities. How
does this type of segregation affect the domestic output of the economy?
47. “Discrimination based on gender may cause a regrettable redistribution of income in favor of males and at
the expense of females, but it entails no loss to society as a whole.” Evaluate.
48. Suppose there are only three labor markets (A, B, and C) in the economy and each of these markets is
purely competitive. The table below contains the demand (or marginal-revenue-product) schedule for labor
in each of these three markets. Assume there are 24 million homogeneous workers in the economy and that
one-half of these workers are male and one-half are female.

(a) What would the wage rates be if the 12 million female workers could only work in labor market C
because of labor market discrimination, while half the 12 million male workers are employed in labor
market A and the other half in labor market B?
(b) Now what would happen to wage rates in each market if discrimination was eliminated and the
amounts of labor were equal in each market?
(c) What would happen to domestic output in each market and for society?
49. Describe the cost of discrimination to society. How is the cost of discrimination illustrated in a production
possibilities curve?
50. (Last Word) Discuss how wealth has changed since 1995. In particular, how did the 2007-2009 recession
effect the median wealth in the United States.
