This report provides evidence of a fairly generalised increase in income inequality over the past two decades across OECD countries, but the timing, intensity and causes of the increase differ from what is typically suggested in the media.

Is there a tradeoff between raising growth and reducing inequality and poverty? This paper reviews the theoretical and empirical literature on the complex links between growth, inequality, and poverty, with causation going in both directions. The evidence suggests that growth can be effective in reducing poverty, but its impact on inequality is ambiguous and depends on the underlying sources of growth. The impact of poverty and inequality on growth is likewise ambiguous, as several channels mediate the relationship. But most plausible mechanisms suggest that poverty and inequality reduce growth, at least in the long run. Policies play a role in shaping these relationships and those designed to improve equality of opportunity can simultaneously improve inclusiveness and growth.

This book provides a comprehensive review of income inequality issues in the OECD in a cross-country setting. It presents a wealth of data and analysis on the formation of inequality and identifies groups of countries that share similar inequality patterns. It also reviews developments at the extremes of the income distribution, namely poverty, top incomes as well as the distribution of wealth. An important contribution of the book is the careful examination of the determinants of the income distribution, such as globalisation and technical progress as well as the effect of a wide range of economic policies that shape the distribution of income. These include in particular labour market regulations, household taxes and transfers as well as in-kind public services. It also sheds light on an under-researched issue: do policies aimed at boosting economic growth raise or reduce income inequality

This book focuses on the role of growth and employment/unemployment developments in explaining recent income inequality trends in Brazil, China, India and South Africa, and discusses the roles played by labour market and social policies in both shaping and addressing these inequalities.

This book explores income inequality across five main headings. It starts by explaining some key terms in the inequality debate. It then examines recent trends and explains why income inequality varies between countries.

This report examines how the two global mega-trends of population ageing and rising inequalities have been developing and interacting, both within and across generations.

Poverty is an important policy issue in OECD countries and the recent crisis has made it even more pressing. This paper highlights poverty rate differences across countries and reviews the various policies to tackle it. The OECD-wide poverty rate has drifted up, reaching around 11% in the late 2000s. In the majority of OECD countries, children suffer from a higher poverty rate than working-age people and poverty is more wide-spread among women than men. Albeit boosting employment is essential to reduce poverty rates durably, work alone does not suffice to eliminate it as in-work poverty is a problem in many countries The redistribution system is effective in reducing poverty. Countries achieving a greater reduction in market-income poverty tend to redistribute more towards people at the bottom of the income distribution. Policies aiming at facilitating paid work along with employment-conditional cash transfers to top-up the income of low-wage workers can offer effective ways to combat poverty. Child poverty is also a major concern because of its adverse long-term effects. Countries with low levels of child poverty combine low levels of joblessness among parents with effective redistribution policies towards children. This suggests these two policy approaches are complementary and relying exclusively on only one of them is likely to be insufficient to reduce poverty among children significantly.

Essays exploring the relationship between economic growth and inequality and the implications for policy makers.

We posit that the relationship between income inequality and economic growth is mediated by the level of equality of opportunity, which we identify with intergenerational mobility. In economies characterized by intergenerational rigidities, an increase in income inequality has persistent effects—for example by hindering human capital accumulation— thereby retarding future growth disproportionately. We use several recently developed internationally comparable measures of intergenerational mobility to confirm that the negative impact of income inequality on growth is higher the lower is intergenerational mobility. Our results suggest that omitting intergenerational mobility leads to misspecification, shedding light on why the empirical literature on income inequality and growth has been so inconclusive.
