Resumen: This paper carries out a time series analysis of the Gini coefficient for disposable income in a sample that includes both advanced and emerging economies. Our results show that, in most countries, inequality has alternated between stationary and nonstationary regimes during the period 1960–2017. These changes coincide with the implementation of structural reforms and with periods of economic and, especially, financial distress. Our findings also suggest that the persistence of income inequality seems to be related to tax progressivity, income for top earners, and working conditions.
