TRENDS IN INCOME INEQUALITY AND ITS IMPACT ON ECONOMIC GROWTH [9 December 2014]

In most OECD countries, the gap between rich and poor is at its highest level since 30 years. Today, the richest 10 per cent of the population in the OECD area earn 9.5 times the income of the poorest 10 per cent; in the 1980s this ratio stood at 7:1 and has been rising continuously ever since. However, the rise in overall income inequality is not (only) about surging top income shares: often, incomes at the bottom grew much slower during the prosperous years and fell during downturns, putting relative (and in some countries, absolute) income poverty on the radar of policy concerns. This paper explores whether such developments may have an impact on economic performance.
Drawing on harmonised data covering the OECD countries over the past 30 years, the econometric analysis suggests that income inequality has a negative and statistically significant impact on subsequent growth. In particular, what matters most is the gap between low income households and the rest of the population. In contrast, no evidence is found that those with high incomes pulling away from the rest of the population harms growth. The paper also evaluates the "human capital accumulation theory" finding evidence for human capital as a channel through which inequality may affect growth. Analysis based on micro data from the Adult Skills Survey (PIAAC) shows that increased income disparities depress skills development among individuals with poorer parental education background, both in terms of the quantity of education attained (e.g. years of schooling), and in terms of its quality (i.e. skill proficiency). Educational outcomes of individuals from richer backgrounds, however, are not affected by inequality.
It follows that policies to reduce income inequalities should not only be pursued to improve social outcomes but also to sustain long-term growth. Redistribution policies via taxes and transfers are a key tool to ensure the benefits of growth are more broadly distributed and the results suggest they need not be expected to undermine growth. But it is also important to promote equality of opportunity in access to and quality of education. This implies a focus on families with children and youths – as this is when decisions about human capital accumulation are made -- promoting employment for disadvantaged groups through active labour market policies, childcare supports and in-work benefits.

Inequality hurts economic growth, finds OECD research
09/12/2014 - Reducing income inequality would boost economic growth, according to new OECD analysis. This work finds that countries where income inequality is decreasing grow faster than those with rising inequality.
The single biggest impact on growth is the widening gap between the lower middle class and poor households compared to the rest of society. Education is the key: a lack of investment in education by the poor is the main factor behind inequality hurting growth.
“This compelling evidence proves that addressing high and growing inequality is critical to promote strong and sustained growth and needs to be at the centre of the policy debate,” said OECD Secretary-General Angel Gurría. “Countries that promote equal opportunity for all from an early age are those that will grow and prosper.”
Rising inequality is estimated to have knocked more than 10 percentage points off growth in Mexico and New Zealand over the past two decades up to the Great Recession. In Italy, the United Kingdom and the United States, the cumulative growth rate would have been six to nine percentage points higher had income disparities not widened, but also in Sweden, Finland and Norway, although from low levels. On the other hand, greater equality helped increase GDP per capita in Spain, France and Ireland prior to the crisis.
The paper finds new evidence that the main mechanism through which inequality affects growth is by undermining education opportunities for children from poor socio-economic backgrounds, lowering social mobility and hampering skills development.
People whose parents have low levels of education see their educational outcomes deteriorate as income inequality rises. By contrast, there is little or no effect on people with middle or high levels of parental educational background.
The impact of inequality on growth stems from the gap between the bottom 40 percent with the rest of society, not just the poorest 10 percent. Anti-poverty programmes will not be enough, says the OECD. Cash transfers and increasing access to public services, such as high-quality education, training and healthcare, are an essential social investment to create greater equality of opportunities in the long run.
The paper also finds no evidence that redistributive policies, such as taxes and social benefits, harm economic growth, provided these policies are well designed, targeted and implemented.
The working paper, , is part of the OECD’s New Approaches to Economic Challenges Initiative, an Organisation-wide reflection on the roots and lessons to be learned from the global economic crisis, as well as an exercise to review and update its analytical frameworks.
