The Fund has recognized in recent years that one cannot separate issues of economic growth and stability on one hand and equality on the other. Indeed, there is a strong case for considering inequality and an inability to sustain economic growth as two sides of the same coin. Central to the Fund’s mandate is providing advice that will enable members’ economies to grow on a sustained basis. But the Fund has rightly been cautious about recommending the use of redistributive policies given that such policies may themselves undercut economic efficiency and the prospects for sustained growth (the so-called “leaky bucket” hypothesis written about by the famous Yale economist Arthur Okun in the 1970s). This SDN follows up the previous SDN on inequality and growth by focusing on the role of redistribution. It finds that, from the perspective of the best available macroeconomic data, there is not a lot of evidence that redistribution has in fact undercut economic growth (except in extreme cases). One should be careful not to assume therefore—as Okun and others have—that there is a big tradeoff between redistribution and growth. The best available macroeconomic data do not support such a conclusion.

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

The sizeable increase in income inequality experienced in advanced economies and many parts of the world since the 1990s and the severe consequences of the global economic and financial crisis have brought distributional issues to the top of the policy agenda. The challenge for many governments is to address concerns over rising inequality while simultaneously promoting economic efficiency and more robust economic growth. The book delves into this discussion by analyzing fiscal policy and its link with inequality. Fiscal policy is the government’s most powerful tool for addressing inequality. It affects households ‘consumption directly (through taxes and transfers) and indirectly (via incentives for work and production and the provision of public goods and individual services such as education and health). An important message of the book is that growth and equity are not necessarily at odds; with the appropriate mix of policy instruments and careful policy design, countries can in many cases achieve better distributional outcomes and improve economic efficiency. Country studies (on the Netherlands, China, India, Republic of Congo, and Brazil) demonstrate the diversity of challenges across countries and their differing capacity to use fiscal policy for redistribution. The analysis presented in the book builds on and extends work done at the IMF, and also includes contributions from leading academics.

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.

Inequality has drastically increased in many countries around the globe over the past three decades. The widening gap between the very rich and everyone else is often portrayed as an unexpected outcome or as the tradeoff we must accept to achieve economic growth. In this book, three International Monetary Fund economists show that this increase in inequality has in fact been a political choice—and explain what policies we should choose instead to achieve a more inclusive economy. Jonathan D. Ostry, Prakash Loungani, and Andrew Berg demonstrate that the extent of inequality depends on the policies governments choose—such as whether to let capital move unhindered across national boundaries, how much austerity to impose, and how much to deregulate markets. While these policies do often confer growth benefits, they have also been responsible for much of the increase in inequality. The book also shows that inequality leads to weaker economic performance and proposes alternative policies capable of delivering more inclusive growth. In addition to improving access to health care and quality education, they call for redistribution from the rich to the poor and present evidence showing that redistribution does not hurt growth. Accessible to scholars across disciplines as well as to students and policy makers, Confronting Inequality is a rigorous and empirically rich book that is crucial for a time when many fear a new Gilded Age.

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.

It is widely assumed that Americans care little about income inequality, believe opportunities abound, admire the rich, and dislike redistributive policies. Leslie McCall contends that such assumptions are based on both incomplete survey data and economic conditions of the past and not present. In fact, Americans have desired less inequality for decades, and McCall's book explains why. Americans become most concerned about inequality in times of inequitable growth, when they view the rich as prospering while opportunities for good jobs, fair pay and high quality education are restricted for everyone else. As a result, they favor policies to expand opportunity and redistribute earnings in the workplace, reducing inequality in the market rather than redistributing income after the fact with tax and spending policies. This book resolves the paradox of how Americans can express little enthusiasm for welfare state policies and still yearn for a more equitable society, and forwards a new model of preferences about income inequality rooted in labor market opportunities rather than welfare state policies.
