Introduction

Some economists find that there is less “income mobility” than there used to be, yet others are not convinced.

To understand the disagreement, we turn our attention to the distribution of income, a key topic in this chapter.

Did You Know That...

• One of every 125 U.S. residents is a “millionaire?”

• About 30,000 people possess personal wealth exceeding $30 million?

• At the other end, there are 37 million U.S. residents in poverty?

Income

• Income provides us a means of consuming and saving

Can be payment for labor

Can be payment for other factor

Can be from gifts and government transfers

Income (cont'd)

• Distribution of Income

The way income is allocated among the population

Copyright © 2008 Pearson Addison Wesley. All rights reserved. 31-9

Income (cont'd)

• Lorenz Curve

A geometric representation of the distribution of income

A Lorenz curve that is perfectly straight represents complete income equality.

The more bowed a Lorenz curve, the more unequally income is distributed.

Income (cont'd)

• Criticisms of the Lorenz curve

1. It does not include income in kind: income received in the form of goods and services.

2. It does not account for the differences in size of households or the number of wage earners households contain.

Copyright © 2008 Pearson Addison Wesley. All rights reserved. 31-12

Income (cont'd)

• Criticisms of the Lorenz curve

3. It does not account for age differences.

4. It ordinarily reflects money income before taxes.

5. It does not measure unreported income.

Example: Why it is Misleading to Examine Only Wages and Salaries

• Today, only about 52% of national income is derived from wages and salaries.

• Total compensation received has remained close to 70% of national income.

The Distribution of Wealth

• Income—a flow—can be viewed as a return on wealth—a stock.

• The distribution of income is not the same as the distribution of wealth.

• Wealth includes tangible objects and human wealth.

Determinants of Income Differences

• We know there are income differences; that is not in dispute.

• A more important question is why these differences occur.

• If we know, perhaps we can change policy, or better understand them.

Copyright © 2008 Pearson Addison Wesley. All rights reserved. 31-20

Determinants of Income Differences (cont'd)

• We will look at four determinants of income differences

1. Age

2. Marginal productivity

3. Inheritance

4. Discrimination

Copyright © 2008 Pearson Addison Wesley. All rights reserved. 31-21

Determinants of Income Differences (cont'd)

• Age-Earnings Cycle

The regular earnings profile of an individual throughout his or her lifetime

Copyright © 2008 Pearson Addison Wesley. All rights reserved. 31-22

Determinants of Income Differences (cont'd)

• Age-earnings cycle

At age 18, earnings from wages are relatively low.

Earnings gradually rise until they peak at about age 50.

Earnings then fall until retirement, when they become zero.

Determinants of Income Differences (cont'd)

• Marginal productivity

Talent

Experience

Training

Investment in human capital

Copyright © 2008 Pearson Addison Wesley. All rights reserved. 31-25

Determinants of Income Differences (cont'd)

• Inheritance 10% of inequality traced to inheritance

• Discrimination Different pay for equal MRP

Equal pay for different MRP

Determinants of Income Differences (cont'd)

• Access to education

Minorities face discrimination in the acquisition of human capital.

Copyright © 2008 Pearson Addison Wesley. All rights reserved. 31-27

Determinants of Income Differences (cont'd)

• Doctrine of Comparable Worth

The belief that women should receive the same wages as men if the levels of skill and responsibility in their jobs are equivalent

Copyright © 2008 Pearson Addison Wesley. All rights reserved. 31-28

Theories of Desired Income Distribution

• The productivity standard “To each according to what she or

he produces”Also called the contributive standard, or

referred to as the merit standard

• Equality—the egalitarian principle “To each exactly the same”

Poverty and Attempts to Eliminate It

• Throughout history mass poverty has been accepted as inevitable.

• Sustained economic growth has wiped out mass poverty in many countries.

• How can there be so much poverty in a nation of such abundance?

Poverty and Attempts to Eliminate It (cont'd)

• Defining poverty

Official poverty level in 2007 for an urban family of four around $21,000

Adjusted based on CPI

Does not include cash and non-cash transfer payments

• Absolute poverty not the same as relative poverty

In a relative sense, poverty will always exist even if absolute poverty eliminated.

Poverty and Attempts to Eliminate It (cont'd)

• Attacks on poverty: major income maintenance programs

90% of all employed persons covered

In 2007, 49 million people received checks averaging $960 a month.

• Temporary Assistance to Needy Families (TANF)

State administered program financed in part by federal grants

The program provides aid to families in need.

Poverty and Attempts to Eliminate It (cont'd)

• Food stamps

Government-issued coupons (or e-debit cards) that can be used to purchase food

In 1964, some 367,000 Americans received food stamps.

In 2007, one in nine citizens received food stamps.

Copyright © 2008 Pearson Addison Wesley. All rights reserved. 31-38

Policy Example: What are Food Stamps Worth?

• Recipients qualify for food stamps because they have low incomes.

• There are times when these recipients need cash more than food stamps.

• Diane Whitmore of the University of Chicago sought to determine value.

Copyright © 2008 Pearson Addison Wesley. All rights reserved. 31-39

Policy Example: What are Food Stamps Worth? (cont'd)

• She found 20 to 30% purchased more food (than if they received cash).

• This group placed an average cash value of 80 cents per $1 in food stamps.

• She found that stamps trade in the underground market for 65 cents per $1.

Poverty and Attempts to Eliminate It (cont'd)

• Earned Income Tax Credit Program (EITC)

Designed to provide rebates to low- income workers

Each year federal government grants $36 billion in benefits.

Over one-fifth of all tax returns claim an EITC.

Poverty and Attempts to Eliminate It (cont'd)

• No apparent reduction in poverty

1973: 11%

1983: 15%

1990: 13.1%

Since fallen to 12%

Health Care

• Health care is intimately related to the distribution of income and poverty

Copyright © 2008 Pearson Addison Wesley. All rights reserved. 31-43

Health Care (cont'd)

• America’s health care situation

Portion of national income spent on health care has risen steadily since 1965.

16% of U.S. real GDP is devoted to spending on health care.

Per capita spending greater than anywhere else in the world

Health Care (cont'd)

• Third Parties

Parties who are not directly involved in a given activity or transaction

Fees may be paid by third parties (insurance companies, government)

Health Care (cont'd)

• Price, quantity demanded, and moral hazard

Large percent of medical services payments made by third parties

Price to the consumer drops and the quantity demanded increases

An individual with a zero deductible may engage in a less healthful lifestyle

At P1 quantitydemanded is Q1

If the price falls to zero, quantity demanded increases to Q2

Health Care (cont'd)

• Moral hazard as it affects physicians and hospitals

Due to third-party payments, patients do not have to worry about the cost of operations and medical procedures.

Physicians and hospitals order more of them since they are reimbursed on the basis of medical procedures.

Health Care (cont'd)

• Medicare expenditures are one of the most serious problems facing the federal government today.

• The number of beneficiaries has increased from 19.1 million in 1966 to more than 40 million in 2007.

• Federal spending on Medicare has increased about 10% a year, adjusted for inflation.

Health Care (cont'd)

• Is national health insurance the answer?

Over 40 million Americans are uninsured at some point during the year.

Federal spending might increase from $60 to $100 billion.

Copyright © 2008 Pearson Addison Wesley. All rights reserved. 31-54

Health Care (cont'd)

• Countering the moral hazard problem: Health Savings Account (HSA)

A tax-exempt health care account

To which individuals can pay on a regular basis

And out of which medical care expenses can be paid

Copyright © 2008 Pearson Addison Wesley. All rights reserved. 31-55

Issues and Applications: Is the United States No Longer an Income-Mobile Nation?

• Past evidence supporting high U.S. income mobility.

• Is mobility giving way to more rigid income-class structure?

• Recent immigrants complicate interpreting the data.
