Latin American countries have succeeded in reducing poverty and income inequality over the last decade thanks in part to both economic growth and deliberate social policy measures. This study provides an overview of the available evidence of the changes in income distribution that have occurred in Latin America over the past two decades and their causes. While some attribute the improvements in distribution to changes in the international economy and the positive trend in the Latin American countries’ terms of trade, others highlight the influence of changes in public policy. Both of these two sets of factors may have played an important role and may have interacted with one another in various ways.
