What’s really happening to inequality? Andy Sumner

It’s evident within-country inequality is back on the radar of some of the major international organisations including UNICEF and UNDP who are leading the wider UN body but, perhaps surprisingly, also the World Economic Forum and the International Monetary Fund.
The basic case is as follows: inequality matters because high inequality can inhibit growth, discourage institutional development towards accountable government and undermine civic and social life leading to conflict especially in multi-ethnic settings.
A number of new studies have pushed thinking forward and a new paper by Chilean Economist Gabriel Jose Gabriel Palma raises a number of questions about the middle classes in particular and their role in redistributive politics.
Five years ago the World Bank’s World Development Report on inequalities was important in that it opened a wider debate on the interaction between types of inequality and how inequality reproduces itself across generations as a result of ‘inequality traps’ or persistent differences in power, wealth and status between socio-economic groups that are sustained over time by economic, political and socio-cultural mechanisms and institutions.
Since then, the impact of inequalities on economic growth has received considerable attention. For example, Klasen and Lamanna in one paper detailed how gender inequalities have held back economic growth and Grimm in another paper that health inequalities impede growth. Recently, the IMF too published a paper by Berg and Osty outlining how high inequality impedes the sustainability of growth spells. High inequality has also been linked to fragility and conflict (see Cramer or ; Stewart et al., papers).
However, exactly what’s happening to within-country inequality isn’t immediately clear.
The new Solt database of the main measure of inequality (known as the Gini after an Italian Sociologist who developed it) was analysed by Ortiz and Cummins at UNICEF who concluded the evidence showed:
Rising inequality in Asia, 1990-2008 but falling inequality in Sub-Saharan Africa over the same time period.
And inequality in Latin America rose slightly 1990-2008 but fell between 2000-2008 and inequality was static in the Middle East and North Africa.
Ortiz and Cummins list a long set of countries where inequality significantly fell between 2000-2008. For example, inequality fell by more than 3 points in Thailand, Malaysia; Brazil, Peru, Argentina, Chile; Lesotho, Malawi, Ethiopia, Burundi, Mali, Sierra Leone, Burkina Faso, Uganda, Nigeria, Gabon.
However, a new paper by Chilean Economist Gabriel Jose Gabriel Palma does a detailed study of within country inequality between 1985 vs 2005 suggesting the gini hides as much as it reveals.
Instead we need to look at each 10% of the population and what they get.
He finds that there is now a surprising similar picture in most countries, noting:
1. The great majority of regions and countries have a relatively similar distribution of income inequality because countries with low inequality at the outset (1985) have got more unequal and countries with high-inequality have got slightly more equal.
2. The middle classes generally get half of the economic pie wherever you look and the middle classes are incredibly successful about protecting their half.
3. Politics is increasingly a fight for the remaining half between the richest 10% and poorest 40% meaning the other half of the distribution is increasingly ‘up for grabs’ between the very rich and the very poor and who can win over the middle classes.
This might begin to explain some of the recent declines in inequality in Latin America as suggested in a paper by Birdsall et al., who argue that ‘social democratic’ regimes (eg Brazil, Chile and Uruguay) are more likely to reduce inequality than ‘left populist’ (eg Argentina, Bolivia, Ecuador, Nicaragua and Venezuela) and both are more likely to reduce inequality that non-left regimes (eg Colombia, Costa Rica Mexico, Peru) and that this is largely due to more social spending and more progressive spending especially so in the social democratic regimes (eg spending on cash transfers targeted to the poorest and greater increases in spending on health and education and increases in spending on basic services – in particular in education, greater increases in spending on primary and secondary schooling rather than on public universities.
These social democrats have strong support in the middle classes and this throws up the question posed by Birdsall et al:
Might the growing middle classes in countries like Chile and Brazil help lock in leftist social democratic political regimes (whether because or despite its concentration in the top quintile of households)? There is no evidence that a large middle class is necessary let alone sufficient to these regimes. But a growing global middle class does seem likely to reinforce effective government that manages moderate redistribution while retaining investor confidence in the likelihood of continuing growth and price stability. Put another way: When is the middle class large enough to become politically salient in supporting or at least tolerating the kind of social and other distributive policies that are good for them but turn out to be good for the poor—for example universal public education?
Food for thought – the middle classes as the new revolutionaries?
















The middle classes have always been the revolutionaries. Defining middle class’s by income is as daft as defining the poor by an arbitrary $1dollar a day threshold.
The middle classes need to understood in mug broader terms: their aspirations, fears, virtues, vices, pop culture, etc. Only then do you realise that they are much larger than you think and much better connected to he rest of the world than you first thought.
Their role in development has been missed out entiry by the “international development” industry because it has focused almost entirely on the hated elites and the poor that need saving.
It seems to forget that middle classes provide services, teach, nurse, police cities, work in NGOs, give loans to smes, write in newspapers, run restaurants and shops, etc.
Without them the number of failed states (and joke states) would be much higher.
the middle classes espouse stability, even when such stability is unrealistic and unsustainable. i believe that such expectations are dangerous and yet they are upheld by institutions such as Radio 4.
such expectations are dangerous because they promote group compartmentalisation manifested in indifference to those below the breadline. Stability trumps everything indiscriminately, resulting in a kind of blinkered, tunnel vision outlook where the only acknowledgement of those in need is charity – thus keeping such unsavoury, troublesome phenomena at a comfortable arm's length.
such expectations are also dangerous because they are incompatible with a capitalist economy, characterised by booms and busts. so no, i don't believe the middle classes (in the UK at least) are the new revolutionaries. but i also don't think you can generalise the middle classes as a global homogeneous group, due to the different histories of individual nations.
Continued/……
nevertheless, actions such as targeting teachers, supposedly middle class, for (arguably passive aggressive) cuts could upset feasibly the usual complacency of this collective in Britain. but i suspect the government is trying to remould the form of the middle class, chipping off teachers and public sector workers, in line with its economic ideals – private sector growth. as long as you have bankers in the middle classes, don't expect a revolution.
so the middle classes are very vulnerable to governmental tinkering, since their values are to appear respectable at all times and these values take precedence over an unseemly self-preservation in times of stress – so normally they will retreat relatively quietly when under duress. Very ironically, perhaps what the middle classes want above all else: stability, would be better served up by a non-capitalist economy.
l'inégalité existera toujours malheureusement ça fait parti de l'équilibre "inégalitaire" mondiale
