particularly in China and India.
In 2008 earning median
income would put the average
Chinese in the top half of the
global income distribution

The horizontal axis
divides the incomes of
the world into

We now live in a world
with a bulge around the
median with significantly
rising incomes for the
entire second third (or
more) of the global
income distribution.
That is the new aspiring
global middle class.
We also see growing
wealth and probably
power of those at the
very top and,
remarkably, stagnant
incomes for both the
people just below the
“enchanted” richest 1 or
5 per cent, and those
poorest in the world.

A Global Perspective
Professor Angus Deaton
Inequality is a knotty subject. There
is little agreement on what ought to
be equal. Should it be a measurable
outcome such as income or wealth;
a hazier outcome such as power or
freedom; or a vague aspiration such
as “equality of opportunity”?
It is often said that the world is
becoming more unequal. But it is
less than clear what is meant by
that. Income inequality between
countries has grown over the past
three centuries but it may now be
narrowing between the world’s
people as a whole. (FT 11-10-13)

Economic Effects of Rising Inequality
Social unrest and civil disobedience
• Strikes and demonstrations over poor pay
and conditions at Fox con in China which
produces IPhones and IPads

Self-perpetuating poverty cycle

• Limited access to health care and education
• Volatile incomes, high debts
• Low savings

Misallocation of scarce resources
Capital investment skewed towards
preferences of the rich
Low collateral – limits entrepreneurship

Capital flight by the rich
Hon Hai Precision Industry
The company started in
the 1980s in Shenzhen,
near Hong Kong
Now Fox Conn has half a
million workers at inland
factories and half a million
at factories on China’s
eastern coast including
Shenzhen.

Shared Prosperity
Shared prosperity is defined as “fostering income growth of the bottom
40 per cent of the population in every country” (World Bank, 2013).
Poverty Reduction Strategies

“There is probably no silver bullet,
one needs to learn from
experience what has worked and
what has not worked, and what
problem what solutions can and
cannot fix.”
Esther Duflo, author of Poor
Economics
Cost of Inducing Extra Education
De-worming and
poverty reduction
One billion people in
the world are
infected with worms;
yet there is cheap,
easy mass treatment
This provides a cheap
way of achieving an
extra year of
education especially
in primary schools
Addressing rural poverty is key

Stiglitz on Inequality
I see us entering a world divided not just
between the haves and have-nots, but also
between those countries that do nothing about
it, and those that do. Some countries will be
successful in creating shared prosperity — the
only kind of prosperity that I believe is truly
sustainable. Others will let inequality run amok.
In these divided societies, the rich will hunker in
gated communities, almost completely
separated from the poor, whose lives will be
almost unfathomable to them, and vice versa.
I’ve visited societies that seem to have chosen
this path. They are not places in which most of
us would want to live, whether in their cloistered
enclaves or their desperate shantytowns.
