Abstract

This study investigates the relative importance of synchronization of income inequality, measured by the Gini coefficient, using a dynamic factor model. This study finds that global factors are relatively stable, whereas regional factors have heterogeneous effects on income inequality fluctuations. Additionally, regional factors account more significantly for the future variance of income inequality than global factors, which is evidence of convergence within each continent.

Keywords: Income inequality, Dynamic factor model, Globalization, Comovement
