This note will describe recent trends in income inequality in both advanced and developing economies and how tax and expenditure policies have impacted on these trends. It will discuss how tax and expenditure policies should be designed to bring about a more equitable distribution of income, as well as to protect the most vulnerable populations during periods of fiscal consolidation.
Staff Discussion Notes showcase the latest policy-related analysis and research being developed by individual IMF staff and are published to elicit comment and to further debate. These papers are generally brief and written in nontechnical language, and so are aimed at a broad audience interested in economic policy issues. This Web-only series replaced Staff Position Notes in January 2011.
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.
This paper analyzes the extent of income inequality from a global perspective, its drivers, and what to do about it. The drivers of inequality vary widely amongst countries, with some common drivers being the skill premium associated with technical change and globalization, weakening protection for labor, and lack of financial inclusion in developing countries. We find that increasing the income share of the poor and the middle class actually increases growth while a rising income share of the top 20 percent results in lower growth—that is, when the rich get richer, benefits do not trickle down. This suggests that policies need to be country specific but should focus on raising the income share of the poor, and ensuring there is no hollowing out of the middle class. To tackle inequality, financial inclusion is imperative in emerging and developing countries while in advanced economies, policies should focus on raising human capital and skills and making tax systems more progressive.
A how-to guide for assessing the impact of fiscal policy on inequality and poverty Inequality has emerged in recent years as a major topic of economic and political discussion, but it is often unclear whether governments can or should do something about it, and if so, what that something might be. This unique volume, edited by Nora Lustig, an equity expert at Tulane University, helps fill that void. Developed by the Commitment to Equity Institute at Tulane, the book examines both the theory and the practical methods for determining the impact of taxation and public spending on inequality and poverty. It provides a step-by-step guide for policymakers, economists, and social planners when analyzing whether fiscal policy has narrowed or widened inequality. The book also has user-written software for conducting a Commitment to Equity Assessment, along with several country studies of these assessments. In addition to serving as a manual, the book can be used as a stand-alone reference for those interested in the methods for assessing the impact on equity of fiscal policy. It also serves as a textbook for advanced undergraduate and graduate courses on public finance and income distribution.
This paper explores how fiscal policy can affect medium- to long-term growth. It identifies the main channels through which fiscal policy can influence growth and distills practical lessons for policymakers. The particular mix of policy measures, however, will depend on country-specific conditions, capacities, and preferences. The paper draws on the Fund’s extensive technical assistance on fiscal reforms as well as several analytical studies, including a novel approach for country studies, a statistical analysis of growth accelerations following fiscal reforms, and simulations of an endogenous growth model.
We study the effects and historical contribution of monetary policy shocks to consumption and income inequality in the United States since 1980. Contractionary monetary policy actions systematically increase inequality in labor earnings, total income, consumption and total expenditures. Furthermore, monetary shocks can account for a significant component of the historical cyclical variation in income and consumption inequality. Using detailed micro-level data on income and consumption, we document the different channels via which monetary policy shocks affect inequality, as well as how these channels depend on the nature of the change in monetary policy.
Major epidemics of the last two decades (SARS, H1N1, MERS, Ebola and Zika) have been followed by increases in inequality (Furceri, Loungani, Ostry and Pizzuto, 2020). In this paper, we show that the extent of fiscal consolidation in the years following the onset of these pandemics has played an important role in determining the extent of the increase in inequality. Episodes marked by extreme austerity—measured using either the government’s fiscal balance, health expenditures or redistribution—have been associated with an increase in the Gini measure of inequality three times as large as in episodes where fiscal policy has been more supportive. We survey the evidence thus far on the distributional impacts of the COVID-19 pandemic, which suggests that inequality is likely to increase in the absence of strong policy actions. We review the case made by many observers (IMF 2020; Stiglitz 2020; Sandbu 2020b) that fiscal support should not be withdrawn prematurely despite understandable concerns about high public debt-to-GDP ratios.
