We analyze microdata from Mexico's survey on household income and expenditures (ENIGH) to study the evolution of income inequality in Mexico over 2004-16, identify its sources, and investigate how it was affected by government social policy. We find evidence of only a small decline in inequality over this period. The observed decline may be attributed to government transfers, notably targeted cash transfers (Prospera) and non-contributory pensions. In 2016, those two programs accounted for more than two thirds of the reduction in the Gini coefficient due to government transfers. Other transfer programs such as farmland subsidies (Proagro), government scholarships, and non-monetary transfers for medical expenditures have not been as effective.

This volume documents and explains the reduction of income inequality that has taken place in the majority of Latin American countries over the last decade.

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.

Over the past decades, inequality has risen not just in advanced economies but also in many emerging market and developing economies, becoming one of the key global policy challenges. And throughout the 20th century, Latin America was associated with some of the world’s highest levels of inequality. Yet something interesting happened in the first decade and a half of the 21st century. Latin America was the only region in the World to have experienced significant declines in inequality in that period. Poverty also fell in Latin America, although this was replicated in other regions, and Latin America started from a relatively low base. Starting around 2014, however, and even before the COVID-19 pandemic hit, poverty and inequality gains had already slowed in Latin America and, in some cases, gone into reverse. And the COVID-19 shock, which is still playing out, is likely to dramatically worsen short-term poverty and inequality dynamics. Against this background, this departmental paper investigates the link between commodity prices, and poverty and inequality developments in Latin America.

This paper demonstrates that high and rising corruption increases income inequality and poverty by reducing economic growth, the progressivity of the tax system, the level and effectiveness of social spending, and the formation of human capital, and by perpetuating an unequal distribution of asset ownership and unequal access to education. These findings hold for countries with different growth experiences, at different stages of development, and using various indices of corruption. An important implication of these results is that policies that reduce corruption will also lower income inequality and poverty.
