The Distribution of Income “God must love the poor,” said Lincoln, “or he wouldn’t have made so many of them.” He must love the rich, or he wouldn’t divide so much mazuma among so few of them. — H.

2. Who Gets What? The Distribution of Income 20 Ways of Considering the Distribution of Income Share distribution of income is the relative division of total income among income groups Socioeconomic distribution of income is the allocation of income among relevant socioeconomic groups For example, it measures how much income the top 5% or 15%, or the bottom 10% gets For example, how much do women get compared to men, old compared to young, black compared to white 20-2

3. Who Gets What? The Distribution of Income 20 The Lorenz Curve A Lorenz curve is a geometric representation of the share distribution of income among families in a given country at a given time Both axes start at zero and end at 100% It measures the cumulative percentage of families on the horizontal axis, arranged from poorest to richest, and the cumulative percentage of family income on the vertical axis 20-3

6. Who Gets What? The Distribution of Income 20 Defining Poverty Poverty can be defined as a relative or absolute concept The U.S. government definition of poverty is a combination of a relative and an absolute measure The poverty threshold is the income below which a family is considered to live in poverty Equal to or less than three times an average family’s USDA-calculated minimum food expenditures 20-6

8. Who Gets What? The Distribution of Income 20 Debates about the Definition of Poverty There are arguments that the poverty line is both too low and too high Those who feel that the poverty line is too low would multiply the food figure by roughly four rather than three since food is now about one fourth of a family’s budget Some argue that the current measure is too high because poverty figures do not include noncash assistance or assets or savings recipients may have Like most economic statistics, poverty statistics should be used with care 20-8

9. Who Gets What? The Distribution of Income 20 The Costs of Poverty Some feel that society suffers when some of its people are in poverty When poverty decreases, the incentives for crime also decrease Some people argue that poverty increased as a result of government tax and spending policies that favor the wealthy Others argue that it is the result of demographic changes, such as the increase in single-parent families 20-9

10. Who Gets What? The Distribution of Income 20 Social and Economic Mobility Concern about poverty has been lessened by the belief that the U.S. has significant economic and social mobility Individuals who work hard can escape poverty In the 1960s and 1970s, studies found that the U.S. had significant upward and downward mobility Recent studies have found that income mobility has significantly declined in the U.S. 20-10

18. Who Gets What? The Distribution of Income 20 Distributional Questions and Tensions in Society Both radicals and libertarians describe the tensions among classes in society better than the mainstream, classless analysis Mainstream economists focus on the share distribution of income Radicals focus on class and group structures Libertarians emphasize the role of special interests in shaping government policy 20-18

19. Who Gets What? The Distribution of Income 20 Philosophical Debates about Equality and Fairness Some philosophers argue that inequality creates diversity that enriches the lives of everyone Others maintain that equality is the overriding goal The Declaration of Independence asserts that “all men are created equal” Objective economists limit themselves to explaining the effect of various policies on the distribution of income 20-19

20. Who Gets What? The Distribution of Income 20 Fairness and Equality Most Americans see fairness as equality of opportunity There are great differences of opinion as to what constitutes “equal opportunity” There are three problems in determining whether an equal income distribution is fair: 1.People do not start from equivalent positions 2.People’s needs differ 3.People’s efforts differ 20-20

21. Who Gets What? The Distribution of Income 20 Three Important Side Effects of Redistributive Programs Society may decide to redistribute income from rich to poor to meet its ideal of fairness There are three side effects of redistribution of income: The labor to leisure incentive effect The tax avoidance or evasion incentive effect The incentive to appear more needy than you actually are Often politics, not value judgments, plays a central role in determining what taxes and individual will pay 20-21

22. Who Gets What? The Distribution of Income 20 Income Redistribution Policies The government redistributes income through direct and indirect methods The indirect method involves the establishment and protection of property rights The direct methods include: Taxation which are policies that tax the rich more than the poor Expenditures which are programs that help the poor more than the rich 20-22

23. Who Gets What? The Distribution of Income 20 Taxation to Redistribute Income A progressive tax is a one in which the average tax rate increases with income It redistributes income from the rich to the poor Based on ABILITY TO PAY THEORY. A regressive tax is a one in which the average tax rate decreases as income increases It redistributes income from poor to rich A proportional tax is a one in which the average tax rate is constant regardless of income It is neutral in regard to income redistribution 20-23

30. Who Gets What? The Distribution of Income 20 Public Choice Theory Politicians are following their own self-interest rather than the interests of those that elected them to office. Government decisions make sense when viewed through the public-choice theory lens. Self-interest motivates participants in both the public and private sectors of the economy. Refer to Activity 58 reading Benefits-Received Principal of Taxation A taxation concept that those who benefit more from government expenditure should pay more taxes to support such expenditure. You are only taxed for goods and services that you consume.

31. Who Gets What? The Distribution of Income 20 Elasticity and Taxes If the purpose is to raise revenue while creating only a minimal amount of DWL, an inelastic demand is preferable. If the purpose is to change behavior a more elastic demand curve is better because a relatively small tax can cause a relatively large reduction in purchases.

32. Who Gets What? The Distribution of Income 20 Moral Hazard Problem Occurs during the rehabilitation stage that involves both offsetting all the damage government has done in the triage and treatment stages and redesigning the system to see that the conditions that caused the problem are resolved Specifically, it is a problem that arises when people don’t have to bear the negative consequences of their actions For example, if a firm or individual is to be unregulated, it should be subject to the consequences of its actions.
