1. Economic development as equalization of opportunities John
E. Roemer Yale University
2. 1 How to measure economic development? Classically, as GDP
per capita The normative justification: Individual Welfare = income
Social welfare is the sum or average of incomes: Can be criticized
in at least two ways: o welfare is linear in income, which ignores
the urgency of some needs over others yi 1 N yi
3. 2 o social welfare is utilitarian, and reflects no concern
for inequality
4. 3 A technological justification? You might say: GDP per
capita is not intended as a welfare measure but as a measure of
industrial capacity. But economic development must mean the advance
of human society; it cannot be a technological concept. A
productive technology run by slaves all of whose product goes to a
small elite should not be considered a highly developed economy. So
I insist the justification of an index of econ development be
corollary to a concept of social welfare
5. 4 Equality of opportunity The distribution of the social
objective (here income) should be independent of circumstances
beyond the control of individuals, but may reflect actions that are
within their control Leveling the playing field metaphor means
compensating persons for the effect on their achievments which
reflect disadvantages beyond their control. The troughs in the
playing field are these disadvantages
6. 5 Language Circumstances are those aspects of a persons
environment that influence outcomes & are beyond his control
The typology is the partition of the popn into types, where all
individuals of a type have similar circumstances With a type,
outcomes will differ because of differential effort
7. 6 Example: The distribution of income by type, defined as
level of parents education in Austria (2005)

12. 11 Inequality of opportunity in Brazil This figure presents
the cdfs of types 1,2, and 3: the red is white-male-urban, the blue
is white-female- urban, and the green is white-male-rural. In
particular, white-female-urban types are better off than white male
rural types. Indeed the white-male - rural cdf is quite a distance
from the other two. 2000 4000 6000 8000 10000 12000 Net market
income 0.2 0.4 0.6 0.8 1.0 quantile
13. 12 Next, I plot the cdfs of types 9, 10, 11. These are
exactly the same as the ones above, except for mixed heads of
household. We see exactly the same story as above: 2000 4000 6000
8000 10000 12000 Net market income 0.2 0.4 0.6 0.8 1.0
quantile
14. 13 Next, I put these two plots on the same set of axes. Now
we see very clearly that the every white head-of- household types
very clearly dominates every mixed head-of-household type. The
white types 1,2,3 are the three on the bottom and the mixed are the
three on the top of the figure.
15. 14 I believe this presents a pretty striking view of the
inequality of opportunity in Brazil with respect to being of white
or mixed race. Next, I add the black story. I compute the CDFs for
black urban male hh, black urban female hh , and black rural male
mm. The order is the same as for mixed and whites. I now add these
three cdfs, in YELLOW, to the graph of the previous six: 2000 4000
6000 8000 10000 12000 Net market income 0.2 0.4 0.6 0.8 1.0
quantile
16. 15 This is interesting. We see that the black and mixed
urban male hh have almost identical CDFs of income. The same is
true for the black and mixed urban female hh. But the black rural
male hh are better off than the mixed rural male hh! So there
appears to be little 2000 4000 6000 8000 10000 12000 Net market
income 0.2 0.4 0.6 0.8 1.0 quantile
17. 16 discrimination against blacks in particular; but whites
have better opportunities than either blacks or mixed.
18. 17 Economic development is equity World Development Report
2006 : Equity and Development . An excellent report. But suffers
confusion of implicitly assuming that development is measured by
GDP per cap, and counterposing this with equity conceived of as
EOp
19. 18 Some quotations from WDR 2006: Greater equity is thus
doubly good for poverty reduction: through potential beneficial
effects on aggregate long-run development and through greater
opportunities for poorer groups within any society (p.2) If the
opportunities faced by children like N. are so much more limited
than those faced by children like P. or S., and if this hurts
development progress in the aggregate, then public action has a
legitimate role in seeking to broaden opportunities.(p.3)
20. 19 Third, the dichotomy between policies for growth and
policies specifically aimed at equity is false (p.10)
21. 20 Growth versus equality of opportunity The conventional
dynamic measure of economic development is growth of GDP per
capita. In its place, I propose growth of the average income of the
most disadvantaged type. One might think that growth of income of
the most disadvantaged type correlates well with growth of GDP per
capita. But this is not so. We need only look at the United States
during the past 20 or so years to see this.
22. 21 We see that real GDP per capita in the US has grown 85%
in the period 1975-2009, while median household income has grown
about 15%. The growth in the US has been sharply biased towards the
most advantaged households.
23. 22 Indeed, let us compare the US and France. During the
period 1975-2006 average income in France grew by only 27%, far
less than the US growth. But now exclude the incomes of the top 1%
of households in both countries. In the US the income of the bottom
99% grew by only 17.9%, while the incomes of the bottom 99% in
France grew by 26.4%!
24. 23 In other words, growth in France was much more
egalitarian than in the US. I dont have the growth figures for the
bottom of income distribution in these
25. 24 countries, but we see that the top 1% made out like
bandits in the US, but not in France. In fact, in the US, the real
income growth went to the top 0.1% of households. Indeed, the top
1% of hh in the US took in 20.9% of total income, while the top
0.1% took in half of that : 10.3% of total income. From these
Lorenz curves, we see that the bottom 50% of households in the US
own about 4% of the total wealth. If we look at financial wealth
which excludes housing, the main form in which the middle class
holds wealth, then the bottom 50% own about 1% of financial wealth.
Indeed, the top 10% own about 80% of financial wealth.
26. 25 This is the main characteristic of a class society. Let
us compare the distribution of wealth in the US to various other
countries. Here are some Lorenz curves:
27. 26
28. 27 We see that the US has by far the most inegalitarian
wealth distribution among these countries. Japan and, remarkably,
China, have the most egalitarian distributions. Wealth, however, is
building up in a very unequal way in China, and the Lorenz curve
for 2013 would probably look much less egalitarian than this one
does. India has a more typical Lorenz curve for a poor capitalist
country very inegalitarian. Although Norways Lorenz curve is quite
inegalitarian, one must recall that the welfare state, which is
large in Norway, provides the security for ordinary households that
only private wealth can provide in a laissez-faire capitalist
economy like the US.
29. 28 Conclusions Equality of opportunity is an ethic which
instructs us to raise the economic position of those who are most
disadvantaged by circumstances beyond their control in a society. A
fairly accurate why of identifying this group is by looking at the
education and income of the parents of the individuals. The most
disadvantaged adults, in a class society, are very closely
correlated with those whose parents were poor and / or had poor
education. Development policies should focus on raising the
economic positions of this group. This means: *focusing on raising
primary-school completion rates, not on tertiary education, which
benefits
30. 29 almost always only the most advantaged in developing
countries *focusing on universal access to health care, especially
with an emphasis on diseases that affect the poor (malaria,
contagious disease) *provision of clean water and adequate housing
for the most disadvantaged *income-support for poor families to
enable them to send their children to school and not to work
*special emphasis on the education of girls *state programs to
counteract predatory private credit markets which are the only ones
the poor have access to in most countries *financing transfers to
the poor through sharply progressive taxation of the rich.
31. 30 The opposition to these policies will come from the rich
and advantaged middle class. One of the most pernicious ideas that
has gained prominence in the last 30 years is that high tax rates
on the rich will discourage innovation and development. This is
simply a Big Lie. Piketty, Saez, and Stanchekova have recently
computed that the optimal marginal income tax rate on the top 1% of
households in the US is over 80%! But the highest marginal tax rate
has fallen from 91% under Eisenhower and JF Kennedy to 35% under
G.W. Bush and B. Obama! This fall in top rates is due to successful
conservative political action, not to economic rationality. The
reason taxes paid by the rich are low in most developing countries
is not due to economic
32. 31 rationality, but due to the fact that the wealthy
control the political mechanism.
