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.

Low-income countries routinely experience exogenous disturbances—sharp swings in the terms of trade, export demand, natural disasters, and volatile financial flows—that contribute to higher volatility in aggregate output and consumption compared with other countries. Assessing Reserve Adequacy in Low-Income Countries presents the findings of an analysis of a range of external shocks faced by these countries, beginning with a discussion of the impact of external shocks on macroeconomic growth, volatility, and welfare. Although sound macroeconomic and prudential policy frameworks are the first line of defense for limiting vulnerability, international reserves constitute the main form of self-insurance against such shocks. The evidence suggests that low-income countries with reserve coverage above three months of imports were better able to smooth consumption and absorption in the face of external shocks compared with those with lower reserve holdings. The analysis also points to the importance of country characteristics and vulnerabilities in assessing reserve adequacy.
