Title: Income Redistribution
1Income Redistribution
2Should government redistribute income?
- This is a normative question.
- It involves a value judgment about whether or not
government should take income from one person or
group of persons and give it to another. - As a positive matter, every decision made by the
government, whether taxing, spending, or
regulation involves the redistribution of income.
- Some programs have unintended redistribution
effects. - Some programs of income redistribution are
intended to redistribution income from wealthy
individuals to lower income individuals. - Such programs are quite explicit in their
purpose. - Politicians take great pains to insure that the
recipients of this redistribution are aware of
the benefit.
3The politics of income redistribution
- In the case of income redistribution to the poor,
the number of recipients are quite large (lots of
voters, perhaps?) and the number of payers is
quite smallonly the fat cats in the top 2 of
income earners. - Or so the politicians would have you believe.
- But is there such a thing as income distribution
to the wealthy? - What about the sugar program?
- In this case, the number of recipients is very
small and very wealthy. - The payers are spread over the entire population
so that the cost to each consumer and/or taxpayer
is very small. - Do you think large campaign contributions from
the sugar growers have anything to do with the
enormous political support they enjoy?
4Other programs of redistribution
- The same argument could be made about dairy
producers, steel workers, certain firms engaged
in foreign trade, and farmers in Iowa. - All of these programs represent redistribution of
income away from the public at large to a very
small group of people who are not living at the
poverty line. - There are also subsidies to a wide range of
individuals who are not living at the poverty
line. - Home owners
- Students
- Recipients of health care
- Retired individuals
5What is the poverty line?
- In the early 60s Lyndon Johnson asked his
advisors for information on the number of
Americans living in poverty. - When no one could give him an answer, he went on
the warpath. - In fact, no one could even give him a straight
answer on what constituted poverty. - Word went out to the bureaucracy to get an
answer. - By the time it reached some low level bureaucrat
in the bowels of the Department of Health,
Education, and Welfare (since renamed Health and
Human Services), an answer magically appeared.
(Actually, Mollie Orshansky of the Social
Security Administration is the mother of the
poverty line) - Thus was born the poverty line.
- The definition has since scientized, but it
started out as a SWAG.
6The poverty line
- Today, the poverty line is defined as a fixed
level of real income considered enough to provide
a minimally adequate standard of living. - Today, it is scientifically measured by
- Estimating the minimum cost of a diet that meets
adequate nutritional standards. - Finding the proportion of income spent on food in
families of different sizes. - And, multiplying the reciprocal of this
proportion by the cost of an adequate diet. - In 2001, (Click here for the 2008 poverty level)
- the poverty line for a family of 4 was 18,244.
- Median income was 42,228.
- And 32.9 million people were below the poverty
line. (11.7)
7Look at some of the numbers
- This chart divides the income pie into five
parts, called quintiles. - Each quintile represents 20 of the population.
(or does it) (also see this) - In a perfect egalitarian society each quintile
would share 20 of the income. - Caution This chart may be misleading since the
numbers do not include the value of in-kind
transfers, among other things. (More on this
later.) - Do you think this might be significant?
- In addition, income inequality may reflect
differences in education.
8Poverty is uneven
- First, Rosen doesnt say whether these figures
are individuals or households. I assume
households since he includes female head of
household as one of the categories. - Second, the poverty rate among this group is
probably due to the fact that the main difference
in family income is the wage differential between
head of households. Also, with female heads,
there is only one wage earner. - Under 18 rate may reflect children of female
headed households. - The 65 and older probably reflects a true success
story.
9The poverty rate
- As for the poverty rate itself, it has been cut
in half over a period of four decades, although
the trend has been up and down. - It might be interesting to note that the poverty
rate declined during the period following the
end of welfare as we know it. - The decade of growth in the 90s may have had
something to do with the decline in the poverty
rate.
10Some Caveats
- In-kind transfers are not included in the
official poverty data. Some of the items excluded
are - Food stamps.
- Housing subsidies.
- Medical subsidies.
- One study concluded that the official poverty
rate would be reduced by more than 20 if we
included in-kind subsidies. - Why do you think we do not include them?
- There are other in-kind transfers you may not
ever think of. - The value of adult time devoted to household.
Think of the stay at home mom vs. the working
mom. - Durable goods provide in-kind transfers. Home
ownership is the major item that provides
income but is not included.
11Other Caveats
- The official figures ignore taxes.
- High income people pay higher taxes.
- Many low income people pay no taxes.
- Some low income families who work, but earn below
a certain level are eligible for the earned
income tax credit (EITC). The EITC is not
included. - Income is measured on an annual basis. What about
looking at income over a lifetime? - Using a lifetime measure, rather than a annual
measure could reduce the poverty rate by 3 or 4
percent. - And as we saw earlier, a quintile may not be a
quintile, i.e., household composition makes a
difference.
12Rationale for income redistribution
- The utilitarian approach is that if you can
increase the welfare of one person without
hurting anyone else, then you have an increase in
social welfare. - This idea is based on three somewhat heroic
assumptions - Individuals have identical utility functions that
depend only on income. - Diminishing marginal utility of income.
- The total amount of income is fixed.
- The second assumption may be the least
unrealistic, but there are serious flaws with the
first and third. (More on this later.) - Lets take a look at the implications.
- Let us assume there are two people in the
economy, Peter and Paul. - (Im not sure what happened to Mary)
13Is there an optimal distribution of income?
- Let OO' be the fixed amount of income.
- Pauls income increases from origin O, Peters
from O'. - With identical MU curves, they intersect at some
point I where each has an equal distribution of
income. - Assume the initial distribution is Oa for Paul
and O'a for Peter. - If we redistribute income away from Peter to
Paul, say an amount ab, welfare increases by area
cefd. - Do you know why?
- Welfare would increase until you reach point I.
Figure 7.1 Model of the optimal distribution of
income
Pauls gain is Peters loss!
14The assumptions
- Are individual utility functions identical?
- Even if they are identical, how can we know that
they are, since each persons utility function is
determined subjectively. - Some have argued that it is an ethical question,
and even if they are different, the government
should act as if they are the same. - Does MU of money decline?
- Suppose it is constant.
- Then redistribution from one to another means the
loss to one is exactly to the gain of the other. - The assumption that the size of the pie is fixed
is the most unrealistic of the assumptions. - It assumes that redistributing income does not
affect the behavior of either the payer or the
recipientthat they will continue to work and
produce as before. - Do you think this is possible?
15Other approaches
- The Maxmin Criterion
- Here the social objective is to maximize the
utility of the person with the lowest utility. - John Rawls argues that this approach is ethically
valid. - He starts with the idea of an original
position. - Since we do not know if we will be rich or poor,
then we would favor some sort of minimum
wellbeing, just in case. - Sort of an insurance policy against being poor.
- The spillover case
- Assume I gain satisfaction from seeing you better
off. - Income redistribution can be a Pareto improvement
in this case. - Need government to overcome free rider problem.
- Think of payments as insurance premiums.
16Other approaches
- The social stability argument.
- Much of the upheaval in South and Latin American
countries in past decades has been a result of a
lop-sided distribution of income. - Communism seemed like an attractive alternative
for people with little hope. - This is one of the reasons that people like Che
Guevara and Daniel Ortega were so popular. - Commodity egalitarianism
- Here, the idea is that only certain commodities
should be distributed equally. - Education and some of the basic necessities of
life come to mind. - Finally, there is the argument that equal
opportunity should be the goalthus, the
distribution of income that results would be
fair. - Some even argue that the marginal productivity
distribution of income is a fair way to slice
the pie. Shares are based on productivity.
Problems arise with imperfections in the market.
17Expenditure incidence
- Remember our various definitions of the word
incidence from our discussion on taxes. - Here, incidence means, simply, who gains the
benefits of the expenditure. - We assume the incidence of redistribution
programs for the poor will be those at the low
end of the scale. - But this is not always true. There are
complications - Relative price effects. Difficult to see how
price changes affect different groups. - Public goods. No way to tell how much people
value the good. - If they have high value, but low tax share,
income is redistributed to them. - The opposite results when the government provides
goods that we do not want.
18In-kind Transfers
- When the government provides goods, rather than
cash, direct to recipients, the result may be a
lower level of utility. - Let AB be the budget line.
- Initial equilibrium is at point E1.
- Assume an in-kind transfer of 60 pounds of
cheese. - Consumer moves to point F on U, a higher level of
utility. Budget line becomes AFD. - Consumer does not have to sacrifice other goods
unless he wants more than 60 pounds. - With cash, budget line becomes HFD, and consumer
would be on a higher indifference curve at E3.
Figure 7.2 An in-kind transfer results in a
lower utility level than a cash transfer
In-kind transfer results in over-consumption of
cheese.
19In-kind Transfers
- In-kind transfers such as those in figure 7.2
cause an efficiency loss. - That is not always the case.
- If indifference curves are skewed more toward
cheese, then the consumer may want to consume
more than 60 pounds. - In this case, either cash or in-kind transfers
result in an efficient solution. - Can you see how fraud might occur in the
previous case? - In both cases, the HF portion of the budget line
is not available with the in-kind transfer. - Consumer can improve his wellbeing by selling
food stamps and using the cash as he sees fit.
Figure 7.3 An in-kind transfer can also result
in the same utility level as a cash transfer
