Income Polarization in Latin America: Patterns and Links with Institutions and Conflict

This paper presents a set of statistics that characterize the degree of income polarization in Latin America and the Caribbean (LAC). The study is based on a dataset of household surveys from 21 LAC countries in the period 1989–2004. Latin America is characterized by a high level of income polarization. On average, income polarization mildly increased in the region in the period under analysis. The paper suggests that institutions and conflict interact in different ways with the various characteristics of the income distribution. In particular, countries with high income polarization and inequality are more likely to have high levels of social conflict.
